SEO refers to Search Engine Optimization, a practice that helps to make a website ranked in front pages of Google. Search Engine Optimization is not the only process to create a site listed on SERP rather Google Ads can also serve this thing, but that would be paid. SEO helps permanent and long-lasting rankings on SERP, and that would be paid less.
