I have purchased 4 Adsense sites. One of these 4 sites makes significantly more money than the other 3. But since this site was listed as the primary URL of the previous owner, I'm not sure if I should apply with this site to Adsense (I don't have an Adsense account yet). Also, the previous owner's Adsense account is still live because he has other sites. Just right now the ads on the 4 sites that I purchased are taken down. So I was initially planning to apply to Adsense with one of the sites that makes less money. But I'm not sure if it will look strange if I don't list the main money making site first.
