Do you like free things? Do you want to learn how to do SEO for free? It is possible.
Just go out there and read a lot of things, but be wary that the people who are writing blog posts are usually wanting to sell you something. It’s quite difficult to get completely objective, free SEO information.
The best way to learn doesn’t necessarily have to be free, but it doesn’t have to cost you a lot of money either. Try a trial subscription to something like SEMrush or sign up for Neil Patel’s Ubersuggest or Moz or any SEO tool that offers an audit.
The onboarding process for these SEO tools should help you learn some quite key things about SEO. But if you’re going to take this route, bear in mind that a lot of the SEO tools mostly focus on auditing and the world of SEO is far bigger than having a well-audited website.
