While I checklist of parameters can be important
@GiGiNetix, I would be careful about relying too heavy on any few parameters. Almost every single day there are sales that break several of the 'standard advice rules'. I check carefully the NameBio daily sales (I do a tweet each day of my take on that day) and I think what surprises me most is the diversity of what sells, even for good amounts.
- Short usually sells better of course, but a number of sales are longer too.CrosswordPuzzles sold for $250,000 last year.
- Hyphens sometimes sell for a lot, especially in Europe, so while agree no hyphens as generally valid, not an absolute rule. For example blackjack-vegas and sci-fi both sold for $50k plus during the past few years.
- Most sales in .com these days are 2 words, but longer names sell too. For example in all time sales AsSeenOnTV, a 4 word domain, sold for $5 million.
- While Google search stats are important for some types of end uses, for others they are largely irrelevant. It depends on the name if that is important.
If you are developing a list, I would add the following.
- Generally (obviously many exceptions) names that emote positive feelings are better.
- Great names need to find that perfect balance between common and fresh, memorable and unique.
Your question re noun/verb etc. is an interesting one. Clearly huge sales in all. I would say nouns maybe preferred, but many many exceptions. Like generally most probably somewhat discount names ending in ed and ing yet two 6 figure names ending in ing sold last year. The suffix feature in NameBio can be helpful in doing your own research.
Thanks for an interesting thread. But alas, I would say there is no formula for success. Or if there was one it would be buy domain names that would add significant value for many potential end users. As simple as that.
