Hi, I do SEO for years now, so I might help, but I do not understand the question. But here are some things that come to my mind:
First of all, having properly set up Google Analytics and Google Search Console is a must. Especially for SEO, you get tons of information from Search Console.
If you want something to monitor SERP (search engine ranking position) of your website and you competitors, I suggest Serprobot. There is a free plan to try it out with small amount of keywords and the paid option is reasonably priced, advantageous to smaller projects/freelancers.
To check your on page SEO, I am recently trying out SEOprofiler. The free/demo version is relatively good for small webpages, where you can easily infer where is what problem.
If you mean some Evo extras that are good for SEO, then I use DLCrumbs to generate breadcrumbs schema syntax, and MultiTV to generate FAQ sections along with appropriate Schema syntax. Actually, the FAQ is performing quite good and it is still relatively new, so there is some first mover advantage. Let me know if you are interested in these, if so I can do some basic tutorial on Schema syntax in Evo.
