Search Engine Optimization, or SEO, is the process of making your website show up higher when someone searches on Google, Yahoo, or any other search engine. When you type something into Google, the page that shows all the results is called the SERP — Search Engine Results Page. The whole goal of SEO is to get your website as close to the top of that page as possible.
SEO involves several key strategies: keyword research (finding what people actually search for), on-page optimization (improving your content and HTML), off-page optimization (building backlinks from other sites), and technical optimization (making your site fast and crawlable). When done right, SEO drives free organic traffic to your website and plays a critical role in business growth. Unlike paid ads, the traffic keeps coming even after you stop actively working on it.
