HI I am trying to active the meta keywords for categories in my Yoast SEO plugin. All of my pages and posts have this option but not my categories. Does anyone know how? I found an article that said I could under general settings I don't see to do this. I am running wordpress 3.4.2. This is what I see in dashboard option under SEO Yoast:
General
Introduction Tour:Start Tour
Take this tour to quickly learn about the use of this plugin.
Default Settings:Reset Default Settings
If you want to restore a site to the default WordPress SEO settings, press this button.
Tracking
Allow tracking of this WordPress installs anonymous data.
To maintain a plugin as big as WordPress SEO, we need to know what we're dealing: what kinds of other plugins our users are using, what themes, etc. Please allow us to track that data from your install. It will not track any user details, so your security and privacy are safe with us.
Security
Disable the Advanced part of the WordPress SEO meta box
Unchecking this box allows authors and editors to redirect posts, noindex them and do other things you might not want if you don't trust your authors.
Thanks!
