I'm running a code learning site (Scrimba.com) that has tons of interactive tutorials created by us and our community. We've heavily underinvested in SEO, so I believe we're leaving lots of traffic "on the table". We have about 130-150K people visiting the site per month, 17% comes from organic search.
I'm curious to hear from other indie hackers how they've improved their SEO, and what results they got. Any checklist I should go through to make sure I've got the basics covered? Any specific approaches that usually works better than others?
I know, of course, that content is king. But we already have amazing content. However, I think it's underutilized when it comes to SEO.
