The bank can appraise the value of my home without knowing how badly I want to sell it, how good my real estate agent is, or whether or not there is someone that absolutely has to have the property at 46 Walnut St. There will be outliers in home sales transactions, but ultimately the value and sale price across all home sales will be statistically correlated but probably not equal.
Domains are often depicted as virtual real estate but it's not a very good comparison.
A domain name is more like a unique piece of art.
- The reseller market is liquid and stable compared to the end user market.
Domain names are a great investment, but liquidity is a problem. There is a stable reseller market for certain types of domains like LLL.com or strong generics where value
on the reseller market is predictable. But for pretty much anything else, liquidity is very low. Unless you're willing to liquidate decent domains at very low prices. Domain names are not commodities, not everybody needs one. Even those who need one will most often handregister an available domain.
In domaining supply by far exceeds the demand, in fact the vast majority of domains are worthless in terms of resale value.
If you compare that to real estate, even in the current depressed market every home has a minimum value. Everybody needs housing.
My feeling is most confound value and sell price.
These tools use to provide a statistically fair estimation of value of generic domains.
There is something else that a bot cannot do: estimate the likelihood of a sale.
You can attempt to deliver a more or less meaningful appraisal price but if there are no end users in sight it means very little.
I think that only human experience and analysis of the market can answer that question. You have to know who and where your potential customers are.
An appraisal is just theory, it doe not mean the domain is likely to sell. That is a critical factor that the bots and the newbies ignore.
The point is that in order to appraise a domain, you also need to look at the market as a whole.
You can have a decent domain with encouraging metrics but no end users. For example adult webmasters are notoriously cheap. So you may have a great domain but nobody willing to pay fair value, whatever the reasons: tight wallets, lack of funding or bias against resellers. For the purpose of selling domains you have to pick the right industries and niches, and avoid those where demand is probably limited. Value and demand go hand in hand.
There is a real need to can quickly estimate the value of domains
I know that some people use appraisal tools to filter through droplists. But it's a very raw form of filtering that is completely different than an accurate appraisal of a given domain. Perhaps it's the only valid use for a bot. I would never use a bot to buy, sell or even renew or drop domains.
