Using more tags for a post

Hello,

I have been using more tags recently which shows up more number of pages indexed in google with those tags. Is that a minus in SEO do google really matters the tags. Should i put a nofollow to the tags or leave them as dofollow. Clarify me.

What do you mean by “tags”?

I think technically there is not harm in doing so.
But it is just that you never know how many is considered safe and after how many your page/site is considered as link farm or spam site for having too many links in the site…
so until you can maintain a balance with it(which is not always easy) ,there is no harm i guess.

If you assign too many tags for single post, then unrelated post may be displayed in search( most of them do tag search) which will annoy people and harm return visitors as well.
so play safe.
