Key Takeaways
- Roughly 64% of companies now outsource lead generation, so the question is no longer if you should consider an online lead generation agency, but how to choose the right one and hold them accountable.
- Your first filter should be how an agency defines and qualifies a lead for your specific ICP; misaligned definitions are the fastest way to burn SDR time and trash internal credibility.
- Average lead-to-customer conversion rates hover around just 2.9%, which means any agency promising overnight miracles or unrealistically high close rates is selling fantasy, not pipeline.
- Before signing, push agencies to share 90-day benchmarks, channel mix, and speed-to-lead SLAs; teams that respond to inbound leads within 5 minutes are up to 21x more likely to convert them.
- Ask exactly how they build and clean lists, what data sources they use, and who owns the data; 42% of marketers complain about low-quality or irrelevant leads, and you do not want to pay for that problem.
- Treat an online lead generation agency as an extension of your SDR team: insist on CRM integration, call and email visibility, and weekly performance reviews so you can optimize cost per qualified meeting, not just vanity lead volume.
Outsourcing pipeline is mainstream now: around 64% of companies outsource lead generation in some form, but plenty still get burned by the wrong partners. This guide breaks down five critical questions to ask any online lead generation agency before you sign. You will learn how to evaluate lead definitions, realistic benchmarks, outbound process, data quality, and collaboration so your sales team gets qualified meetings instead of noise.
Introduction
If you are looking at online lead generation agencies right now, you are not alone.
Recent research shows roughly 64% of companies now outsource at least part of their lead generation, and nearly 69% of B2B firms plan to increase lead gen investment in the next year. That is a lot of budget flowing into outside vendors. Sci‑Tech Today
The upside is obvious: faster pipeline, less internal hiring drama, and access to expertise and tools your team may not have. The downside? Pick the wrong partner and you burn your domains, your brand, and your reps’ trust in outsourced leads.
This guide is written from a sales development point of view. We will walk through five questions you should ask any online lead generation agency before you sign, along with what good and bad answers look like, and how it all plays out in your SDR and AE world.
By the end, you should be able to vet agencies like a pro, structure a 90‑day pilot that actually proves ROI, and avoid the most common ways outsourced lead gen goes sideways.
Why Choosing the Right Online Lead Generation Agency Matters
Before we get into the questions, let us ground this in reality.
Lead gen is mission‑critical and getting more complex
B2B leaders are under pressure to feed hungry pipelines. In one large 2025 study, about 51% of B2B companies in the US said getting new marketing qualified leads is urgent, 30% called it mission‑critical, and only 12% felt they had enough leads. Sci‑Tech Today
At the same time, buyers are harder to reach and pickier than ever. Around 80% of B2B engagements now happen digitally, and research suggests 6-10 decision‑makers are often involved in a typical B2B deal. Sci‑Tech Today
That is a lot of noise to cut through.
Most leads are not ready, and most programs are not great
Zooming out, the average lead‑to‑customer conversion rate across industries is only about 2.9%. Sci‑Tech Today In other words, 97 out of 100 leads never turn into revenue.
It is no surprise that roughly 42% of marketers say low‑quality or irrelevant leads are one of their toughest challenges. Sci‑Tech Today
So when you bring in an online lead generation agency, you are not just buying meetings. You are betting that their process, their data, and their people will beat those averages.
Outsourcing is mainstream, but many are first‑timers
Outbound and sales development outsourcing are no longer niche. One analysis of B2B sales outsourcing found that 49% of companies say they would consider using outsourced sales development, yet 59% have never actually used it before.
Combine that with broader lead gen data showing 64% of companies already outsource lead generation, and you get an interesting picture: outsourcing is common, but a lot of leaders are still learning the ropes as they go. Sci‑Tech Today
That is where the five questions come in.
Question 1: How Do You Define and Qualify a Lead For Our Business?
If you only remember one question from this article, make it this one.
Why this matters
Nothing will torpedo your outsourced program faster than misaligned lead definitions. Marketing thinks a lead is any form fill. Sales only wants meetings with budget and pain. The agency may call anything with a pulse a lead because that is what their contract incentivizes.
Given that only a tiny slice of leads ever convert, you cannot afford to flood your AEs with conversations that never had a chance. You want a partner obsessed with lead quality, not just raw counts.
What to ask the agency
Start with some direct questions:
- How do you define a marketing qualified lead versus a sales qualified lead for a client like us?
- What specific firmographic and role criteria must be true before you add someone to a campaign?
- What information do your SDRs or systems need to capture before passing a lead or booking a meeting?
- How do you handle no‑shows and reschedules? Do they count as leads or meetings in your reporting?
Then flip it around: ask them to explain your ICP back to you. A good agency will ask about your ACV, sales cycle length, win‑loss patterns, and current best accounts before they even attempt to define a qualified lead.
What a good answer looks like
A strong online lead generation agency will:
- Talk about fit and intent, not just contact info
- Include role, authority, tech stack, and pain alignment in their qualification logic
- Treat a lead as an MQL only if it matches your ICP and shows some level of engagement
- Treat a sales qualified lead or meeting as something your AEs would actually accept, not just a calendar slot
- Offer to co‑create a qualification checklist and map it to CRM fields
They should be completely comfortable with you rejecting leads or meetings that do not meet agreed‑upon criteria, and they should want that feedback to tighten up their filters.
Red flags to watch for
- They use vague phrases like warm lead or hand‑raiser without specifics
- They lump everything together under a single lead definition
- They cannot explain how they handle leads that are outside your ICP but respond anyway
- They shy away from tying compensation to qualified meetings or pipeline created
In practice, if you get this question wrong, you will know in the first month. Your AEs will stop joining agency‑booked calls or will complain that prospects are confused about why the meeting exists. Fix the definition before you fix anything else.
Question 2: What Results Can We Realistically Expect in the First 90 Days?
You are not buying a dream, you are buying a model. And that model should come with benchmarks.
Why this matters
Average lead‑to‑customer conversion is low, buyers are busy, and your market has its own quirks. Any agency promising 20% close rates on cold outbound or 100 meetings a month without knowing your ACV is waving a giant red flag.
At the same time, you cannot manage what you cannot measure. If you do not align on realistic 90‑day expectations, every weekly check‑in becomes hand‑waving.
What to ask the agency
Push for specifics:
- For clients similar to us in deal size and industry, what does the first 30, 60, and 90 days typically look like in terms of meetings and pipeline?
- What is a realistic target for:
- Held qualified meetings per month
- Show rate
- Conversion from meeting to opportunity
- Estimated pipeline created
- What activity levels (emails, calls, touches) are required to hit those numbers?
- How do you adjust if early results lag? What dials do you turn first?
Also ask how they factor in speed‑to‑lead. Multiple studies show that responding within 5 minutes can make you up to 21 times more likely to qualify a lead, and 35-50% of deals often go to the first vendor that responds. Gitnux, Zipdo
If they are handling inbound or high‑intent leads, you want to see a concrete SLA around response time.
What a good answer looks like
A credible agency will:
- Frame months one to three as a progression: testing and list cleanup, then optimization, then scale
- Share benchmarks or ranges instead of single magic numbers
- Reference the realities of your sales cycle length (enterprise vs SMB)
- Talk about both leading indicators (reply rates, connect rates) and lagging ones (opportunities, revenue)
- Be willing to sign up for targets around cost per held meeting or cost per opportunity, not just activity volume
They may also highlight that it takes iteration to find the right combination of messaging, channels, and personas. That is not an excuse; it is how good outbound is built.
Red flags to watch for
- Guarantees that have nothing to do with your context, like promising 50 sales‑qualified meetings in month one for any client
- No mention of show rate or opportunity conversion; they only talk about meetings booked
- Vague language when you ask for references or sample baselines
- A focus on lead volume instead of lead value, even though most marketers now prioritize quality over quantity
If they dodge this conversation, you will be arguing about “performance” forever because you never agreed what success looked like.
Question 3: What Does Your Outbound Process Actually Look Like?
You want a partner with a process you can plug into, not a mystery box.
Why this matters
B2B lead generation lives or dies on execution details: channel mix, timing, messaging, and tech stack. The data backs this up:
- Around 87% of B2B businesses rely on email for lead generation. Digital Silk
- Email still converts, but so does the phone. One recent sales development report found that roughly half of all pipeline is generated over the phone in many orgs.
- Multi‑channel campaigns can lower cost per lead by about 31% compared with single‑channel approaches. Sci‑Tech Today
If an online lead generation agency is doing only batch‑and‑blast email from a single domain, they are playing the game on hard mode.
What to ask the agency
Dig into their playbook:
- Which channels do you use for us and why? Email, phone, LinkedIn, retargeting?
- What does a typical outreach cadence look like over 2-4 weeks?
- How do you handle deliverability on email (domain warm‑up, list hygiene, spam monitoring)?
- How do your SDRs or systems prioritize which leads to call or email each day?
- What tools do you use for sequencing, dialling, data enrichment, and reporting, and how do they integrate with our CRM?
- Can we listen to anonymized call recordings or see example email threads from similar programs?
You are looking for signs of sophistication: AI‑assisted personalization, thoughtful testing plans, and serious attention to sender reputation and compliance.
What a good answer looks like
A mature agency will describe:
- A multi‑channel sequence strategy, not just “we send five emails”
- A clear separation between experimentation and scaled sending
- Use of personalization beyond first name and company, ideally pulling in role‑specific pains or recent news
- A call strategy that targets best‑fit accounts, not random dialing
- A tech stack that plays nicely with your CRM and provides real‑time reporting on activity and performance
They should also be able to talk about how they adapt outreach for different buyer personas, regions, or segments.
Red flags to watch for
- Single‑channel outreach (email only) with no mention of phone or LinkedIn
- No answer when you ask how they manage deliverability and domain health
- Reliance on generic templates with minimal personalization
- No way for you to review calls, emails, or sequences during the engagement
Remember, your buyers are already inundated. One Gartner survey in 2025 found 61% of B2B buyers prefer a rep‑free buying experience and 73% actively avoid suppliers that send irrelevant outreach. Bad process does not just fail; it damages your brand. Gartner
Question 4: How Do You Build, Validate, and Maintain Prospect Lists (And Who Owns the Data)?
Great copy on bad data is still bad outbound.
Why this matters
List quality is one of the biggest levers in lead generation. Yet more than 40% of marketers complain about low‑quality or irrelevant leads. Sci‑Tech Today
If your online lead generation agency cannot explain exactly where contacts come from, how they are validated, and how often they are refreshed, you are one bad list away from high bounce rates, damaged domains, and frustrated reps.
Data ownership is just as important. You do not want to spend six months funding pipeline only to realize the agency owns all the prospect data and you cannot reuse it.
What to ask the agency
Get very concrete here:
- What data sources do you use to build lists for clients like us (third‑party providers, in‑house research, intent data, etc.)?
- What criteria will you use to select accounts and contacts for our campaigns?
- How do you validate emails and phone numbers before outreach?
- How frequently do you refresh or clean lists for a long‑running program?
- How do you handle bounced emails, invalid numbers, or do‑not‑contact requests?
- Do we own all the data and activity history in our CRM, even if we stop working together?
Also ask if they can incorporate your existing account lists, target ABM accounts, or enrichment data. The best partners will improve what you have, not throw it away.
What a good answer looks like
A solid agency will:
- Combine multiple data sources and human research for coverage and accuracy
- Use verification tools to check emails and phone numbers before sending
- Enforce bounce and complaint thresholds to protect domain health
- Refresh data regularly for longer programs, especially in fast‑changing industries
- Contractually agree that you own all prospect records, notes, and history in your CRM
They may even show you example list build criteria and sample account lists from similar segments (with sensitive details removed).
Red flags to watch for
- Vague answers like “we have our own databases” with no further detail
- No mention of verification or data hygiene processes
- High dependence on scraped lists from questionable sources
- Any hint that you must pay extra or stay on retainer to keep access to data you funded
In B2B sales development, your prospect database is a strategic asset. Treat it that way.
Question 5: How Will You Work With Our Team and Protect Our Brand?
You are not buying a separate machine; you are plugging something into your existing revenue engine.
Why this matters
Even the best agency will fail if they are misaligned with your internal team. Poor knowledge transfer, weak communication, and mismatched workflows are some of the top reasons outsourced lead gen underperforms. Multiple industry analyses point out that when onboarding is rushed and collaboration is thin, most of the failure has nothing to do with channel tactics and everything to do with how the partnership is structured.
On top of that, outreach is brand exposure. Every email and call shapes how prospects see you. With 73% of buyers saying they still prefer to hear from sellers by email, you cannot afford to let a third party wing it with your logo on the line. Sci‑Tech Today
What to ask the agency
Drill into how they operate day to day:
- What does your onboarding process look like? How long does it take, and who needs to be involved from our side?
- How do you learn our product, positioning, objection handling, and competitive landscape?
- How will we communicate? Weekly calls, shared Slack channel, joint dashboards?
- How do you route leads and meetings into our sales process, and what SLAs do you expect from our reps?
- How can we review messaging, sequences, and call recordings on an ongoing basis?
- How do you handle complaints, unsubscribes, or brand‑sensitive issues that come up in the field?
Also ask about contract flexibility: month‑to‑month vs annual, performance reviews, and exit options if it is not working. Long, inflexible contracts create vendor lock‑in that can make agencies complacent.
What a good answer looks like
A strong partner will describe:
- A structured onboarding process that covers ICP, personas, value props, and sales process in detail
- Clear collaboration rhythms: weekly performance calls, shared messaging docs, and fast feedback loops
- Full transparency into outreach activity, including access to email templates, live sequences, and call recordings
- Joint responsibility for results, not a “throw it over the wall” mindset
- Flexible terms with defined performance checkpoints at 60 and 90 days
They should also encourage your AEs and marketing team to be involved, not just leadership. The people taking the meetings should have a say in whether lead quality is improving.
Red flags to watch for
- Minimal onboarding: “Just send us a deck and we will take it from there”
- No access to calls or actual emails, only summary reports
- One‑way communication where you get a monthly PDF and that is it
- Long contracts with no performance review or opt‑out clauses
If you would not hire an internal SDR leader who works like that, do not hire an agency that does.
Red Flags When Evaluating an Online Lead Generation Agency
Beyond the five questions, here are some quick patterns that should make you slow down or walk away.
- Guaranteed results that ignore context. Promises like “we guarantee 40 SQLs a month” without asking about your ACV, niche, or brand awareness.
- Overemphasis on vanity metrics. They brag about total leads, open rates, or dials, but cannot map activity to opportunities and revenue.
- No industry relevance. Zero case studies, references, or examples in anything remotely close to your space or price point.
- One‑size‑fits‑all playbooks. Everything sounds generic. No mention of persona‑specific messaging, competitive differentiation, or your existing channels.
- Cheap for a reason. Rock‑bottom pricing usually means scraped lists, no real SDR training, and minimal oversight. You end up paying the true cost later in reputation and repair.
Take your time. With outbound, it is far cheaper to spend an extra few weeks vetting than to fix a broken program six months in.
How This Applies to Your Sales Team
So how do these questions translate into day‑to‑day reality for your SDRs, AEs, and RevOps?
For sales leaders (VP Sales, CRO, Head of SDR)
Use the five questions as your evaluation framework and build your business case around cost per qualified meeting and pipeline, not top‑of‑funnel vanity numbers. Pull your historical data: how many meetings per month per SDR, what your current show rates and meeting‑to‑opportunity conversion look like, and what your fully loaded SDR cost is.
Compare that to proposed agency economics. If an agency can beat your internal cost per qualified opportunity with equal or better win rates, you have a strong case. If not, you either need to renegotiate the scope or keep building in‑house.
For SDR and AE managers
Your job is to make sure agency‑sourced leads fit your team’s workflow. Get involved early in defining qualification criteria and handoff rules. Set clear SLAs for how quickly your reps must follow up with agency‑booked meetings and inbound leads they surface.
Given that being first to respond can win you 35-50% of deals in many markets, speed‑to‑lead is not optional; it is a key coaching KPI. Zipdo
For RevOps and Sales Ops
You are the connective tissue. Own the CRM integration, routing logic, and reporting. Make sure every agency‑generated record is tagged with a consistent source and that activities, meetings, and opportunities are all trackable back to specific campaigns.
Build dashboards that let you compare:
- In‑house vs outsourced cost per meeting and per opportunity
- Opportunity win rates and average deal sizes by source
- Performance by segment or region
When (not if) you iterate on ICP or messaging, you will need this data to make smart decisions.
For founders and small teams
If you are pre‑SDR or still founder‑led on sales, this framework keeps you from betting the farm on the wrong partner. Start narrow: one product, one region, one ideal customer profile. Set a modest but clear 90‑day target for qualified, held meetings and pipeline, and treat the engagement as an experiment.
Use the five questions to stay out of trouble:
- Are we aligned on what a good lead looks like?
- Are targets realistic for our stage and price point?
- Do we know exactly what outreach will look like and how it will hit our brand?
- Do we own the data, and can we keep learning from it?
- Are we working as one team, or are we outsourcing and hoping?
If you can answer yes to those, you are in a much better spot than most first‑time outsourcers.
Conclusion + Next Steps
Online lead generation agencies are not magic. They are force multipliers.
Used well, they can help you ramp new markets faster, stabilize pipeline when hiring is tough, and let your AEs focus on deeper discovery and closing instead of endless prospecting. Used poorly, they can burn time, money, and reputation while leaving you with nothing reusable when the contract ends.
The difference usually comes down to discipline in the buying process.
If you start every conversation with these five questions:
- How do you define and qualify a lead for our business?
- What results can we realistically expect in the first 90 days?
- What does your outbound process actually look like?
- How do you build, validate, and maintain prospect lists (and who owns the data)?
- How will you work with our team and protect our brand?
…you will filter out 90% of the wrong fits before they ever touch your CRM.
From there, structure a 60-90 day pilot with clear, revenue‑tied KPIs, full CRM integration, and weekly performance reviews. Treat the agency like a virtual SDR pod, not a black‑box vendor, and you will get far more value out of the relationship.
And if you want a benchmark for what a modern, transparent B2B lead generation partner looks like, study how specialists like SalesHive structure their programs: multi‑channel outreach, AI‑powered personalization, US‑based and offshore SDR options, no annual contracts, and a track record of 100K+ booked meetings for over 1,500 clients. That kind of model is what you should hold any online lead generation agency up against.
The bottom line: the right partner will not just get you more leads. They will give your sales team more of the right conversations, with the right people, at the right time-and that is what actually moves revenue.
📊 Key Statistics
Expert Insights
Start With Lead Quality, Not Lead Volume
When you talk to agencies, make the very first conversation about how they define a qualified lead for your exact ICP, deal size, and sales cycle. Push them to describe their qualification criteria in enough detail that your AEs would actually be happy to take those handoffs. If they talk mostly about volume and not buying intent or fit, keep shopping.
Demand Transparency Into Their Process and Tech Stack
A good online lead generation agency will happily walk you through their channels, cadences, and tools, and show how they plug into your CRM. Ask to see sample sequences, reporting dashboards, and call recordings before you sign. If they cannot show you what is under the hood, you will not be able to manage performance once the campaign is live.
Align on 90-Day Benchmarks, Not Month-One Fantasy
Most outbound engines need 30-60 days to test messaging, clean data, and hit stride, so your focus should be on realistic 90-day targets for qualified meetings and pipeline. Ask agencies for typical ramp curves by ACV and industry, and how they pivot when early results lag. Anyone promising dozens of SQLs in the first couple weeks is either guessing or cutting corners.
Treat the Agency Like an SDR Pod, Not a Vendor
The best results come when you treat your agency like a virtual SDR team: shared Slack channel, weekly standups, and tight feedback loops on lead quality. Give them visibility into win/loss notes and deal stages so they can refine targeting and messaging instead of operating in a black box.
Make Speed-to-Lead and Data Ownership Part of the Contract
Put specific expectations around response times to inbound or high-intent leads into your agreement, because being first to respond often wins the deal. Also lock in that you own all prospect data and activity history in your CRM so you are not starting from scratch if you ever switch providers.
Common Mistakes to Avoid
Choosing an agency based purely on price or logo sheet
Going with the cheapest option or the one with the flashiest homepage often means generic lists, templated outreach, and a mismatch with your market complexity. That leads to burnt domains, annoyed prospects, and reps who stop trusting any outsourced meetings.
Instead: Prioritize agencies that show depth in your segment, share clear playbooks, and are willing to walk you through realistic economics. Compare partners on cost per qualified meeting, show rate, and pipeline created, not just retainer size.
Never aligning on a clear definition of a qualified lead
If marketing, sales, and the agency all define a good lead differently, you end up with bloated pipelines full of junk that AEs quietly ignore. That destroys trust in the program and masks the true ROI of outbound.
Instead: Co-create a qualification checklist that includes firmographics, role, pain, timing, and buying power. Bake it into scripts, email logic, and CRM fields so everyone knows exactly what an MQL and SQL look like for your team.
Letting the agency run on their own tools without CRM integration
When the agency lives in their own siloed platform, you get exported CSVs and vanity reports instead of real pipeline visibility. That makes it impossible to track attribution, forecast accurately, or see how leads progress to revenue.
Instead: Insist that all activity syncs into your CRM with clear source tags and that you have admin-level access to any external dashboards. Your operations team should be able to see the full path from first touch to closed-won inside your own system.
Signing long-term contracts without performance checkpoints
Multi-year or rigid annual contracts can make agencies complacent and leave you stuck with an underperforming program. You lose leverage to demand changes when meetings are not converting or list quality is weak.
Instead: Favor month-to-month or short-term agreements with clear performance reviews at 60 and 90 days. If a longer term is required, negotiate opt-out clauses tied to agreed-upon KPIs like cost per held meeting or qualified pipeline generated.
Ignoring how the agency will represent your brand in market
Bad outreach does real damage: 73% of B2B buyers say they actively avoid suppliers that send irrelevant outreach, so sloppy messaging can close doors you have not even knocked on yet.
Instead: Review and approve messaging, subject lines, and call talk tracks before launch, and ask for ongoing visibility into emails and call recordings. Make brand protection and relevance non-negotiable parts of the engagement.
Action Items
Document your ICP and qualification criteria before you talk to agencies
Write down target industries, company sizes, geos, tech stacks, and the job titles you care about, plus non-negotiable qualification questions. Share this during discovery so agencies can propose a realistic plan and you can quickly spot generic approaches.
Create a standard list of questions to ask every online lead generation agency
Base it on the five core questions in this guide so you evaluate vendors on the same criteria: lead definition, results and benchmarks, outbound process, data and ownership, and collaboration model. Capture answers in a comparison sheet to make selection more objective.
Set 90-day success metrics tied to revenue, not just meetings
Define targets for qualified meetings, show rate, conversion from meeting to opportunity, and pipeline value created. Use these to structure your contract, performance reviews, and any variable compensation or bonuses for the agency.
Require CRM integration and reporting access during onboarding
Make sure the agency can push contacts, activities, and opportunities into your CRM with clear source codes. Have RevOps or Sales Ops verify the setup and build dashboards that compare outsourced vs. in-house performance.
Align your internal team on how to handle agency-generated leads
Coach AEs and internal SDRs on SLA windows, follow-up sequences, and how to provide feedback on lead quality. If your team ignores outsourced leads or responds days later, no agency on earth can save your ROI.
Pilot with one product, region, or segment before going all-in
Start with a focused program where you can measure lift clearly, then expand if the economics check out. This reduces risk, speeds up learning, and gives you real data to justify a larger outsourced motion.
Partner with SalesHive
On the email side, SalesHive’s eMod engine uses AI to research prospects and personalize every message at scale, turning proven templates into highly tailored outreach that earns replies instead of spam complaints.

❓ Frequently Asked Questions
What is an online lead generation agency in a B2B context?
In B2B, an online lead generation agency is a specialist firm that uses digital channels like email, phone, LinkedIn, and paid media to identify, contact, and qualify prospects for your sales team. The better ones act like an outsourced SDR function: they build lists, run outbound sequences, qualify interest, and book meetings directly on your reps' calendars. Their job is to create predictable, sales-ready pipeline so your internal team can focus on discovery and closing, not list building and cold prospecting.
When does it make sense to outsource lead generation instead of hiring SDRs in-house?
Outsourcing makes a lot of sense when you need to ramp pipeline quickly, you lack internal SDR management experience, or your market is new and you want to test it before building a full team. Recent research suggests that fully loaded SDR costs often run into six figures annually when you include salary, tech stack, and management, and many internal teams still miss quota. In contrast, a good agency can spin up in weeks, bring proven playbooks and tools, and run a structured pilot so you can validate ROI before committing headcount.
How long should I expect before seeing results from an online lead generation agency?
You can usually get some early meetings in the first 3-4 weeks, but realistic evaluation should happen over a 60-90 day window. The first month is often about message testing, data cleanup, and warming up domains and callers. By months two and three, you should see steadier weekly meeting volume, clearer conversion rates from meeting to opportunity, and good signal on whether the channel mix and ICP are right. Any agency promising full pipeline transformation in the first couple weeks is overselling.
What KPIs should I use to measure an online lead generation agency?
For B2B sales development, focus on cost per held qualified meeting, show rate, conversion from meeting to opportunity, and pipeline value created, not just meetings booked. Also track deliverability metrics (bounce rates, spam complaints), connect rates on calls, reply rates on email, and speed-to-lead for inbound or high-intent prospects. Over time, compare opportunity win rates and deal sizes from agency-sourced leads vs. your other sources to ensure the quality is truly there.
How do I protect my brand reputation when an agency is doing outbound on our behalf?
Start by reviewing and approving all core messaging: email templates, subject lines, call talk tracks, and LinkedIn connection messages. Require the agency to prospect only into accounts that fit your ICP, enforce sending limits and warm-up process on email domains, and get access to call recordings and email logs. Given that most B2B buyers prefer digital, rep-light experiences and 73% say irrelevant outreach makes them avoid suppliers, brand-safe outreach is not optional; it should be baked into your contract and QA process.
Should I give the agency direct access to my CRM?
In most B2B environments, yes, with the right guardrails. If the agency cannot log activities, update lead statuses, and create opportunities in your CRM, you will be stuck reconciling spreadsheets and manually stitching together performance. Work with RevOps to create roles, permissions, and fields that keep your data model clean while allowing the agency to operate efficiently. Make sure all agency-generated records are clearly tagged so you can report on their performance separately from other channels.
How do I know if an online lead generation agency is a good fit for my industry or ACV?
Ask for case studies and references from companies that look like you in terms of deal size, sales cycle, and target personas. Selling a 500-dollar SaaS tool into SMB is very different from selling a 250-thousand-dollar platform into enterprise, and you want proof the agency understands that motion. Have them walk you through sample sequences, list criteria, and expected activity volumes for an account that resembles your ICP, and make sure their expectations align with your sales process and capacity.
