Market share refers to the percentage or proportion of sales a company captures in a specific market. This metric is important because it can provide insight into a company's competitiveness and position within its industry. One way to increase market share is through list building, which involves actively compiling and managing a list of potential customers. By targeting these leads , a company can expand its customer base and ultimately increase its market share.

There are four main types of market share: unit, value, customer, and channel.

1. Unit Market Share: This is the percentage of units sold by a company compared to the total number of units sold in the market. For example, if Company X sells 100 widgets and the total widget market sells 1,000 widgets, then Company X has a 10% unit market share.

2. Value Market Share: This is the percentage of revenue generated by a company compared to the total revenue generated in the market. For example, if Company X generates $10 million in sales and the total widget market generates $100 million in sales, then Company X has a 10% value market share.

3. Customer Market Share: This is the percentage of customers that buy from a company compared to the total number of customers in the market. For example, if Company X has 100 customers and the total widget market has 1,000 customers, then Company X has a 10% customer market share.

4. Channel Market Share: This is the percentage of sales made through a particular channel (e.g., retail, online) compared to the total sales in that channel. For example, if Company X sells 10% of all widgets sold online, then it has a 10% channel market share for online sales.
