I have 4 sites that I was going to redirect to a brand new site. But im wondering if it would be ok to redirect them to a site I already have ranking instead. It is sitting on page 2 and I think it just needs a push but im not sure if redirecting to it will cause it to get pulled. It is about 5 years old and a good domain but its just not quite strong enough to go to page 1. Should I use a fresh domain i have which is 2 months old with nothing on it or would it be ok to redirect to the established site?
