Curious How To Establish A Web Site's Value?

For starters, you can use this excellent tool, http://www.dnscoop.com.

Simply enter the domain address and you get a nice laundry list of key information from various source, in just one click such as; Domain age, IP Information, PageRank Value (if it's real or fake), Alexa Ranking, BackLinks, Domain List on same Server and a Text Link Ads Value.

I just stumbled upon this tool while searching online one day, it saves time and gives a great start point if you are considering the purchase of a web site to assist with search engine marketing, Internet marketing objectives or to establish a link value for web site monitizing.

I would love to hear about other web site tools that assist with determing a value for a website.
