Meta keywords in Yoast SEO
We’ve removed the meta keywords feature in Yoast SEO from version 6.3. Meta keywords haven’t had a use for a long time. Originally, they were designed to indicate a page’s main keyword. You could rank for whatever keyword you want. Google saw the meta keywords tag being abused. They officially confirmed in 2009 that they didn’t use them. In that blog, they also stated they already started disregarding the meta keywords many years before 2009. So their removal from our plugin has been long overdue.
