Hey guys recently i bought three domains and the seller says it not dropped , but some says it dropped. I used domain tools it says not dropped. Created 2001 and Exp 2010 Here the list of domain. Are they dropped or not.. http://www.hallmp3.com http://www.houstonservice.com http://www.stockdrill.com thanks
how did you check that .. http://web.archive.org/web/*/http://www.houstonservice.com - it has not data for 2006 2007
Agreed. That's a start. And like others have said, there's not simply ONE tool that will enable you to see what a domain is worth. There's many,many factors that determine value, and at the end of the day, a domain is only worth what someone is willing to pay you for it.
The downside of the dropped domain is that it will affect the SERP and the backlink it associate with before the drop.
