Rank Math scores posts out of 100, based on categories Basic SEO, Additional SEO, title readability and content readability. The readability suggestions all seem more practical (with the exception of "Your SEO title doesn't contain a number" - now I know why so many blog posts are titled" 20 ways to ..." etc).I only have that as the transition words as the problem and the face is still green so I will ignore. I'll be interested to hear if Rank Math gives different responses though. To be honest I found the SEO bit more useful than the readability... I'll be the judge of that!
It uses traffic light colours for the score out of 100, then ticks and crosses for the suggestions. It isn't compatible with Yoast, but you can import your stuff from Yoast (keyword, snippet) and Rank Math deactivates Yoast when it's installed. Also, it appears on the right of the page with the score at the top so you don't need to scroll to the bottom of the post to keep checking your score.
Another thing to add to the list!Tell you one thing which rankmath is good at which is schemas

Rank Math looks good so far anyway, although if you like to know if your writing style is passive etc then Yoast would be best. My most passive post according to Yoast isn't being flagged up by Rank Math.
