This SEO Plugin is literally almost TOO Good

Required Plugin for most any site. Well documented, and thoroughly researched. Has more features than the majority of site owners will know how to deal with.

4 star rating is only because it may be TOO feature rich for many content editors. I would like to see some default settings changed, like exclusion of redundant content from xml sitemaps – based on standard WordPress installs.

I never launch a site without WordPress SEO by Yoast.
