What Is SEO?
Search Engine Optimization (SEO) is the process of improving a website so that it ranks higher on search engines like Google, Bing, and Yahoo. The main goal of SEO is to increase organic (free) traffic by making your website more relevant and useful for users.
For example, if someone searches for “best running shoes”, Google displays the most relevant websites at the top of the search results. SEO helps your website become one of those top-ranking results.
