Hmm. Maybe. They do say, of course, that the data supplied is for proof of concept only. Maybe they have the ability to enlarge the sample at some point?
To me, though, take off the ".com" on those and look at the query and I think you get more logical results.
Also, it may well be that more women look at the tractor site itself - whilst their husbands are on the tractors, the wives are doing the admin!
