Nice idea Rated 3 out of 5 stars

Nice idea but some erroneous SEO tests and not everything is checked.
However developer seems very proactive and I'm sure new versions will improve usefulness.
-still a better UI than most, you can install this and it doesn't get in the way of everything like some of the plugins I've tried.

This review is for a previous version of the add-on (1.5.5). 

The recommendations are based on official Google SEO guidelines but you are free to offer better suggestions
