Hi there, hope you are all fine. I own 4 websites , one of them is 4 years old (have about 9000 unique), pr 2 with many backlinks, some of them are crap some of them are good, rest 3 sites are younger, also pr 2, with less backlinks. Now I stop to work in the niche and the sites are useless for me. However I was wondering what to do with the sites. I should redirect them to any of my new sites ? Even if they are totally different niches? I will get penalised? Anyone have experience with this issue? Or I should just throw them and thats it?
