About 10 years ago when I made my website using wordpress I would add tags to every post I wrote and would spam it with keywords like every noob does, just like I would do with meta keywords. I even had one of those tag clouds on my footer. Anyway, I havent used tags for years and when I did they were a bit spammy. So, do they still matter? Should I go back and 'clean up' my old post tags? I could noindex the tags if that helps? Or is it just not important enough?
