What do you say is a good overture score?
If a keyword has 1000 searches in the past month, then is it good enough?

What if a keyword (say website builder) has a score of 100. Then will people buy it? What price can I expect to get?

A good overture score is not just the sign for buying the domain name related to it. It must have less competition if possible and is the .com version of the query keyword available?

Do some research and then you can make a guess yourself if that domain name would be good enough or not.

Once my friend got some domain names with overture around 13500+ and the very next month it went down to 50. Now that was because the domain name was related to cats and one of the cat did harmed someone and it was all over in news. So people were searching for it. Next month all the buzz was going down. The overture data he saw was of previous month when the searches were made and the month he purchased that domain names it was already falling down.
