Hey.
I used the Seo Plugin from
http://www.marketingop.us long time for my blogs and was happy with it. But since that guy stopped working on it (quite long ago) i changed to all in one seo plugin.
Now i noticed that that plugin does only use the things i add myself in meta keywords and desciption and title in its options.
All these things were done by the other seo tool automaticaly , using the Tags i entered on all posts( for example it used 20 or 30 tags as meta keywords).
Is there any plugin that does this also automaticaly or is using tags as meta keywords generally not a good idea?
