Does no-follow for pages affect site ranking?

[Mirian]

Hey, I have a question.  On my site, it's divided into the main site and the blog is in a subfolder of same domain.  Within the main site (same domain), there are MANY checkout pages and other internal pages we use though all with "NO FOLLOW" on each.  Despite it having "NO FOLLOW", will it affect our blog rankings in any way or domain ranking?"

Hi Maria,

I've never heard anything about the presence of nofollow affecting rankings negatively. Just be careful none of the content you want ranked is blocked!

You shouldn't use the nofollow tag property for internal links. Doing so used to preserve your PageRank, but it was changed a few years ago so that links with nofollow just result in link juice evaporation.

But to answer your original question, the nofollow tags should have no impact on your blog. But do yourself a favor and remove the nofollow tags.
