Should links on a family bar be no follows?

[SBRMarketing]

I have a network of sites that we use a family bar for to get the user to where they want to go but as I am looking at my link profile, i keep on seeing these links everywhere. (DUH, of course)

Question is, should these links be no follow? Could these links hurt me?

Theoretically if the links make sense you should go for it but if it seems unnatural you should remove the links that are pointing to your network sites but practically i have seen that this actually hurt the SERP rankings especially when the link profile looks something like you said!

In my opinion, ideally if possible remove the links and get some quality links to those websites but if you think that  removing a link is not the option then you left with no-following the links only and you should go for it!

Hope this helps!
