Is Estibot more or less reliable for the valuation of your domains?
Estibot appraisals are generally best when used as relative values to its other appraisals. It is based on other sales, but generally estibot takes into consideration many statistics, including keyword frequency in general, and how often the exact keyword phrase is searched for, how many ads are being put up for the domain, how much clicks are paying out, etc...
Domains that get high appraisals from estibot generally have very strong statistical strengths. Whether you can get someone to pay you that is a way different story. Probably not. But estibot has information under the 'estibot power' link that discusses the evolution of algorithms and shows what domains it appraised sold for.
The estimates have value if you take them in context with the other statistics and use some common sense and don't take the estimates *too* literally.
The appraisal plus the statistics give you a rough idea of a domain's strengths and how you can best leverage it for profit, if at all. Whether it's better to park, brand, direct market (flip), etc...
If a domain appraises at some high number of thousands of dollars by estibot, you know it has *something* going for it... something that give it traffic/ranking/profit potential. Doesn't mean you don't need to work or develop a domain to see any of that potential.
You have to be careful that you don't reg trademarks, and that you also consider the competition. Estibot cannot figure out what is trademarked, etc...
Also be careful of getting a good estimate on a domain that still cannot compete for traffic very well in it's niche (little fish in big pond syndrome). Study the niche before you clicks
