Use title or taxonomies for META keywords:

Hi isasam,

The first question is why do you want Meta Keywords on your site? There is no search engine that uses Meta Keywords any more so there’s no reason to have them on your site.

Actually, we don’t know exact algorithm do some bots use Meta Keywords or not, but I need them since some russian search bots use them.

If there is no reason to use them, why its still used for example by such a big ebay.com or amazon.com etc ? they never removed Meta Keywords

Hi isasam,

You can use the aioseop_keywords hook to provide your own keywords. Google does not use meta keywords, whereas Yandex has not confirmed that they ignore them, but in practice it doesn’t seem to be very useful as a ranking factor even there.
