I want to buy an old expired domain name which had expired 3 years ago. (checked using wayback machine). It was used in 2000 until 2005 and expired after that. I've check on Google and no SERP result, of course no PR as well. So how can i know that this domain being banned from Google and also Adsense. Information: I can't check the appearance with wayback machine because it show an error. However, if it show something and i think that's not a spammy site. How can i ensure it? Thanks for the advices!
you don't. Buy it and see afterwords if it gets indexed again or not. If it doesn't put a reconsideration request and tell them you just bought it.
