Thank you very much for this plugin and the SEO training on your website!

Anyway, something could be improved:
1) it could not be enough to get the 1st page of google for 300 words written in the content;
2) keyword density for many SEOs doesn’t seem to be a ranking factor anymore.

3) if I write a keyword with an apostrophe ” ‘ ” or with a short word (like of, in, an, for, etc) and I don’t put the sign or the short word in the seo title or in the introduction, it says that the exact keyword is not there.

These 3 factors are evaluated for the green/yellow/red semaphore as writing new posts, but in my opinion these 3 factors should be better contextualized or deleted.
