I have a doubt...if I link my different web pages, with the no follow, Google will penalize me in the SERPS? They are topic related... Thanks!
If your pages are related then link them with dofollow. Google doesn't mind you interlinking sites if they are related. It's when you put a bunch of unrelated links in a footer that causes you problems.
So I will be Ok to put links for my other sites...let s say in the menue, and reapeting them in the whole web page?
