Most of us think of WhoIs first when researching a domain, but there is a domain service more elegant and ultimately more useful, DomainColeta.com. Besides reverse WhoIs search, this service will research information about server location, backlinks information, outgoing links, hosting service, reverse IP lookup and more. It also searches for domains with the same Adsense ID. Just like other services that provide website information, traffic and visitor numbers are wildly inaccurate for sites with less than 100,000 visitors per month.
