How does SEO work exactly?

Search engines like Google look at two things when evaluating your website and deciding where to rank it – RELEVANCE and TRUST. RELEVANCE is the content of a website and the code behind the scenes. If your code is optimized and the content on your site is relevant to a search, Google will move you up in the rankings. TRUST refers to how many other sites on the internet are linking back to your site. If a large number of high-quality sites are pointing to you, Google will start to trust you and move you up in the rankings.
