I notice this is a lot: some domains make no sense whatsoever, so sellers end up having to come up with all sorts of complex explanations as to what the domain in question stands for.

In my opinion, if the domain itself doesn’t automatically make people come up with possible uses (in other words, if the seller has to come up with complicated explanations as opposed to letting the domain speak for itself), it’s probably not that great.

That’s the mistake a lot of people make. Instead of buying domains with obvious reseller as well as end user market value, they settle for “this kinda-sorta might make sense” alternatives and, needless to say, the domains in question are often worthless.

As a general rule of thumb, remember what I wrote in the second paragraph:

In my opinion, if the domain itself doesn’t automatically make people come up with possible uses (in other words, if the seller has to come up with complicated explanations as opposed to letting the domain speak for itself), it’s probably not that great.

I think that’s a fairly reasonable approach.

And remember: cheap domains aren’t necessarily bargains. If you buy a cheap domain that has no reseller market value whatsoever and no end user potential then no matter how cheap the acquisition price was, you threw money out the window.
