SEO to many people seems like this big mystery and this very technical skill, but in reality it's just using content to drive traffic.

Years ago there was a lot more gamesmanship to SEO. You could essentially lazily trick your way into the search rankings. If you're curious to learn more about this look into Made For Adsense or MFA as it was called. Essentially people could throw up poorly written one page web pages with keywords stuffed in and get to the top of Google.

Over the years algorithms and AI have become much more advanced, they can tell if something is readable and written in a quality manner. It's also much more about user engagement and if people are actually finding that content helpful.

SEO these days is less about backlinks and on site page structure and tags and more so just about creating quality content.

Sure it will help to learn a bit about SEO. Learn about H1 and H2 tags, link structure, how to get backlinks, but don't spend too much time getting hungup on the ins and outs and just create quality content.

If you're a business trying to drive traffic try to think of questions a potential customer may have or ask and write content that addresses those questions.
