I’ve mentioned before how, rather than going on expensive training SEO courses, a self-motivated person might like to work through a really good “SEO basics” guide and then put the money saved towards some software tools and services which could really make a difference. But what sort of tools? Search Engine Journal comes to our aid with The Last SEO Tool on Earth, an article where it asked a couple of dozen experts: “If you were only allowed to have one SEO tool, what would you pick?”
Even if you don’t have money to spend, quite a few of them are free, and possibly surprising too. It’s worth a read.
