Understanding Technical SEO

The realm of SEO is vast, but often, it's the technical elements that make the most significant difference. Unlike traditional SEO, which focuses on content creation, keyword research, and link building, technical SEO focuses on a website's backend aspects, such as structure, coding, and metadata. Think of it as working under the hood of a car, fine-tuning everything so that the engine (or, in this case, your website) runs smoothly and efficiently.

However, technical SEO requires a specialized skill set, including the ability to read and edit code and utilize advanced website analysis tools. This is where Technical SEO Specialists come into play.

Key Components of Technical SEO

Having defined what technical SEO is, it's time to explore its fundamental components. These include;

  • Website architecture
  • Site speed and performance
  • Mobile-friendliness
  • Site Security

Website architecture refers to the overall structure of a website (how well or poorly your website is organized). To improve your website structure, technical SEO agencies organize your website's content into categories and subcategories, use an internal link structure that connects related pages, and an easy-to-understand URL structure. This also improves website performance and helps search engines rank your website better.

The other fundamental aspect of technical SEO is site speed. A study conducted by Google revealed that bounce rates increased by 32% when loading time exceeded 2 seconds. To help improve your website's loading speed, a technical SEO partner conducts advanced speed checks and implements counter strategies such as image optimization. This helps improve server response time.

Third on this list is mobile-friendliness. With the increased use of smartphones, ensuring an optimal experience on mobile phones is vital. It not only influences Google rankings but also aligns with mobile-first indexing. To improve their website's mobile performance, a business owner can use a responsive design that adjusts the website layout to the device's screen size.

P.S. Incorporation of structured data markup, technical search engine optimization, Google Search Console, and performing a technical SEO audit are other essential components of technical SEO.

Benefits of Hiring a Technical SEO Company

Engaging a technical SEO company is a strategic move because these specialized agencies not only conduct technical site audits but also identify issues with your site and then create strategies to resolve these issues.

Some of these strategies include;

  • Getting rid of duplicate content and broken links
  • Improving loading speed and website performance by optimizing images
  • And adding meta tags and title tags to increase your site's visibility

And that's not all. A technical SEO consultant will also help improve the user experience on your website, get you higher rankings, and improve your content strategy.

How to Choose the Right Technical SEO Agency

Selecting an appropriate technical SEO agency might seem challenging. Here are some steps to help you make the right choice:

  1. Evaluate the agency’s expertise. It is safer to go for an agency with a proven track record.
  2. Look for agencies with niche experience.
  3. Assess the skills of their team.
  4. Examine testimonials and case studies.
  5. Understand the specific SEO techniques and strategies that the agency plans to implement.
  6. Ensure they align with best practices and your unique goals.

Also, communication is key when working with an SEO agency. Establish clear expectations for the frequency and detail of progress updates.

Lastly, research the agency’s pricing structures, which may include monthly retainers, project-based pricing, or hourly rates. This will help ensure they fit within your budget and service requirements.

Mistakes to Avoid When Working with a Technical SEO Company

Although partnering with a technical SEO company can yield significant benefits, it’s important to stay cognizant of potential pitfalls. One common issue to avoid is duplicate metadata, especially prevalent in large sites and e-commerce platforms, which can hinder technical SEO performance.

It’s crucial to evaluate a technical SEO agency’s effectiveness through their past results and case studies, and be wary of those that guarantee specific rankings. Be attentive to technical errors like 404 pages, as they indicate that a webpage does not exist and can negatively impact the user experience. Also, understand the impact of unnecessary redirects on user frustration and conversion rates, and how clearing cookies and evaluating third-party plugins can resolve these issues.

DIY Technical SEO vs. Hiring a Professional Agency

Choosing between DIY SEO and outsourcing to an agency isn’t a straightforward decision. On one hand, DIY SEO can be significantly less expensive, particularly because some tasks can be executed for free or with the use of low-cost tools. However, learning the basics of SEO can be achieved within a few hours, but the ongoing time commitment for effective implementation can be substantial.

On the other hand, outsourcing to an agency or specialist with technical SEO expertise has several advantages:

  • It saves time, as professionals can efficiently resolve technical SEO issues.
  • Agencies can provide monthly reports that track progress, making it easier to analyze data and measure success.
  • Hiring a professional can be more cost-effective in the long run, especially for competitive keywords.

Ultimately, the decision should take into account the individual or business’s time, budget, and willingness to learn and apply SEO techniques.

Industry Trends: The Future of Technical SEO

Looking ahead, several emerging trends are influencing the future of technical SEO. One of them is generative AI, which is reshaping search behaviors by introducing AI-generated summaries directly in response to queries. This emerging AI capability minimizes the necessity for users to visit websites from search results, potentially impacting website traffic.

Another critical trend is the rise of AI copywriting tools, enabling more efficient content creation and increasing SEO competitiveness as businesses generate content with greater ease. Notably, the rise of AI copywriting tools has led to:

  • More efficient content creation
  • Increased SEO competitiveness
  • A shift in SEO strategies to account for a wider range of search engines beyond Google, such as Microsoft Bing’s adoption of ChatGPT and its user growth.


In conclusion, technical SEO is a crucial aspect of digital marketing, responsible for optimizing a website’s backend elements to improve search engine rankings and overall performance. Whether you opt for DIY SEO or hire a professional agency, it’s essential to understand the key components of technical SEO, the benefits of professional services, and the common mistakes to avoid. As we look towards the future, be prepared for the rise of generative AI, AI copywriting tools, and the diversification of search engines that will continue to shape the SEO landscape.
