The same as real property appraisals, they're worthless. in the real estate industry we use a word, a particular word. It's an opinion of value versus an estimation. A computer or software can estimate but it cannot give an opinion. There are too many factors to arrive at a fair opinion of value. Software cannot see everything. Do not rely on any automated program for your house or domain property.
Hi acronym007
I agree with you on the fact that you can not base a selling price only based on an script result. What ever the result can be accurate compared to market price, it will always have to be talked with domain expert.
Domain appraisal tool are not made to replace experts.
Let me give you a concrete example of how a wise use can be :
Let's say you a snapnames addict, always searching for good opportunities.
Snapnames among other, gives you every day huge list of expiring domain.
Example:
https://www.snapnames.com/file_dl.sn?file=snpexpingexclusive1list.zip
There is juste too many domain to go on a forum a say, "please, appraise those 50 000 domains for me"
At that point, you need scripts.
An appraisal tool can help you find the 20 good domains out of 50 000 within seconds.
Now, you made a selection, the good method is to ask expert for a review, that will takes into account all parameter a script just can't handle.
There is other way a domain appraisal tool can help.
Example 2.
You are thinking about a business about delivering flower, and, of course, all best domain are already taken.
A appraisal tool can help to provide domain list and sort then by potential value (based on limited factor, of course).
That will make the job easier.
