Please explain overture references

[CrazyGuy]

I see references to things I don't understand, like:

"domains listed in overture"
Overture is PPC - what value is being listed there on a domain purchase.

"overture +ext = xxx"
What is this refering to - I guess it's to do with the domain name as keywords and the number of searches for that keyword being performed at overture, but I can't get an exact correlation between the numbers quoted and what I'm trying.

Can someone please clarify how overture is used to assess domain values?

Thanks

the higher the OVT the more people that searches it thus the higher the uniques it'll get and possibly get more clicks with more uniques thus higher price.

however, it is not exact science since some lower OVT perform better than higher OVT.

Yeah - I kinda understood it was that kinda idea, but I still don't understand the specific metrics people are quoting. 2 recent examples of domains sold here as "OVT domains":

donsdivas.com (26)
webmsnmessenger - OVT score of 70 apparently

26 and 70 whats, as demonstrated where?

if you search for these at overture you get 0 and 3 results respectively, if you use the suggestion tool it says they get searched for 0 and 300+ times/month respectively.

Not understanding this at all.
