I've just bought a domain last week, put a few quality backlinks on it and it didn't get indexed by google. I checked archive.org (should have done that before I know) and saw that the domain was used as a link farm before. Ok. I thought that maybe this is the reason why google doesn't index it, so I bought another aged domain. I checked the archive.org and saw nothing fishy. I know it's only 3 days since I bought the domain but there should be around 100 quality backlinks on it already and google still didn't index it. Usually I get my sites indexed within 48h. Any ideas why it won't index?
