I've been doing SEO as a digital marketer for some time now. Please dump other tools for SiteGuru... I did struggle with technical SEO. I used SEO Frog Premium, but now Site Guru gives you everything you need to optimize any page for SEO.

I have nothing to complain about, and the UI is simple and straightforward. 
If you've read my review, best luck with your purchase. This is my first review of Appsumo.
