Best HANDS OFF Wordpress SEO Plugin?

What is the best wordpress plugin that automatically optimizes posts and pages without you having to do anything?

Titles, Meta, etc. Preferably the ability to include a keyword on all pages.

For example, I upload 400+ spun PLR articles but do not want to go to each one and check the SEO config. Does Yoast do this?

Don't put spun content on your own website if you want it to rank well. 100% original only.
