Check every major county in any state with Overture's tracking tool. You will see a similar pattern. I doubt everyone searching all those county.com domains owns WebP.O.S.ition.
That people search "Location".com isn't hard to accept. Los Angeles County, population 10 million, is one of the largest counties in the U.S. The Overture numbers - a few hundred searches for LosAngelesCounty.com for the month - are rather modest, but I think they are likely more accurate than your software's "0".
Not to miss the forest for the twig, I'd be more than happy to own LosAngelesCounty.com, wouldn't you? Let's see.... business listings, real estate, dining. Probably 1 billboard, for 1 month, on the L.A. freeway would create enough mindshare to launch the site forever in the minds of a few million people.
Ya. Local search. Score 1 for David in the battle of the behemoths.
