...not that I know of.
It would be nice with all that friggin' money to re-tool that Overture Suggestion Tool.
Last info I got was that a guy with a big account inquired about the Tool and the info he got was...
...it was made by a couple guys a long while ago and they left Overture. Overture themselves don't know *exactly* where the data is pulled from- So they tell people.
But if ya check site stats, the order and ranking of phrases may differ but the popular OV phrases are generally the popular Google phrases.
Would be nice for Google to come out with a similar Tool though.
