Keywords are not always logical

I was giving some free advice to some friends over a meal. They are having problems getting bookings for their new rental house in the South West of France, between Bordeaux and Toulouse. We were brainstorming some keywords, trying to guess what keyword people searched on when Googling. We were pretty sure that South West France would be the best one. We all thought that the most accurate name, Quercy, would not be a c good choice.

Later I checked it all out using Market Samurai. We were certainly right about Quercy. But South West France had a surprisingly low score too. In fact, it scored lower than The Lot France. Who would have guessed that?
