I recently setup a small python script to dish out site metrics for expired domains in a neat little csv file. I am amazed at what I am finding, but most of the expired domains are not relevant to my niche. I just found a few expired domains with PA/DA both above 30 and non spammy link profile. This website is in the pharmaceutical niche, and most of my sites are confined to tech and gaming. Should I use this domain and build a gaming/tech blog on it? Or should I keep looking for relevant domains? What is your opinion about using expired domains from different niche?
