your opinions about website seo score tools

Good morning all

I launched a few months ago my site:

https://seositechecking.com/

it is a site that can help to calculate the reinforcement score of other websites through forms containing several information and solutions and then a final score.

in relation to the structure of the website (the appearance, the functionality, the pages) if there are tips or opinions... because we have professionals here in the field I have put my project here and I like that you test it and write down your opinions and tips here and I want to determine and develop it.
