I found siteguru to be very insightful. Got a precise evaluation of the on-site SEO of my website with step-by-step recommendations to improve it.

I've bought and trialled lots of SEO tools in the past but SiteGuru is the one I'll be sticking with. I've always struggled with SEO because I've found it confusing and didn't understand what all of the data meant but SiteGuru is simple enough that I can understand it and makes it easy to see what I need to improve. A solid tool for SEO that most people would find useful.

What I really like about SiteGuru is that it not only covers all the SEO tools you need to improve your website, but it also is such a clean tool which works very intuitive.
