Best place to determine the sort of names that MAY make you money don't look in the appraisal section.
Look instead in the for sale section - the names that have SOLD can give you an idea of what people are buying.
Also read, listen to the various forms of media (TV, RADIO, MAGAZINES) to get an idea of the latest trends/fads.
Don't make these mistakes most newbies make.
1/ Too many abbreviations or Leet Speak names
2/ If the name needs explaining , usually not good name.
3/ never buy Useless .ext's just because the keyword is available i.e. Tourism.ml will never sell
4/ CelebrityNames and TM's are Poison Don't touch
5/ Don't buy based on Appraisal site valuations. Nearly 100% of all newbies make that mistake.
6/ Names that can be developed will always sell for higher prices than novelty / gimmick names
7/ Remember the all important rule. Domains are like lottery tickets. Most that are purchased are not winners.
