This post is to show that when we get too confident of ourselves, we atart making mistakes, as we all know... I have been developing SEO for three years now. I have launched a new website last month. I've been developing it, and keep improving the others. BUT... Why doesn't this last one gets ranked? Checked everything, and no matter what, this still wasn't geting any results! Finally, I found out! It really was a rookie mistake... Robots.txt! I forgot to unset it. It was blocking bots as I was building it... The most simple thing was avoiding my site of organic results... Have you had moments like this?
The best way you can avoid simple things like this is basically a checklist of all the basic things you have to do in development or use an seo program that can catch the mistakes that you don't catch since we know that it's the little things that can make or break site success in serps.
