With this post, I start a series of SEO related articles where I'm going to share my 11+ years experience in SEO to help you understand better how it works. The top-rated comment on Reddit in the post I saw last week What do you wish developers knew about SEO? was: «The most dangerous thing in SEO is a developer that thinks he understands SEO. They so rarely do». So this article is for developers who want to deliver a better SEO for clients and SEO beginners, as well as for the entrepreneurs, who are about to hire an SEO agency. You need to understand, why some sites are on top in search results and some will never be there.
