First of all, hello everybody this is my first post here. I've been lurking around but recently decided to join and become an active contributor to the forum. Anyways, I've got this option to buy a good expired domain with lots of diversified backlinks and it a pretty good domain name as well. My only concern about this is that I want to build an authority site on an unrelated niche with the previous one. So I was wondering what kind of effect would this produce on the longterm? I plan to monetize the website with Google Adsense, so anyone who has got a certain experience with this one is welcomed to offer me his opinion. Thanks in advance.
