SEO stands for Search Engine Optimization. It is the process of improving a website’s structure, content, and authority to increase its visibility on search engines such as Google, Bing, and Yahoo.

The primary goal of SEO is to attract organic traffic. Organic traffic refers to visitors who find your website through unpaid search results rather than paid advertisements.

For example, if someone searches for “best digital marketing services,” websites that are well-optimized for SEO are more likely to appear on the first page of search results. Since most users rarely go beyond the first page, higher rankings can significantly increase website traffic and potential customers.
