words.ca and estibot appraisals

Sedo.com has posted on its homepage the sale of words.ca for $1800.00 USD.

A great price for a great generic domain name. The domain is currently being parked but hopefully the buyer has a development plan for this name. What this post really is about is the convoluted way ESTIBOT appraises domain names. Below is their appraisal values for words.TLD for the .com, .net, .org, .info, and .ca TLDS.

words.com – $69000.00
words.net – $1000.00
words.org – $600.00
words.info – $6000.00
words.ca – $150.00

I find it very interesting that words.info is appraised at $6000.00. I guess that’s because it sold for $5200.00 on 7/6/2007. So I guess words.ca will now be appraised at over $1800.00 once ESTIBOT finds out about the sale. Evaluations based on previous sales doesn’t make any sense to me since I don’t personally care what someone else values the name at. A fair appraisal should be based on keywords, backlinks, PPC values, etc. Now obviously most seasoned domainers know that ESTIBOTs appraisals should not be solely used to valuate their domains but a lot of new domainers seem to use them to justify their pricing.
