Has anyone had any success with 'Yelp'? They hound me regularly, but I have tried pay per click and it was a nerds fantasy, lots of clicks, but no one showed up.
I told them I would pay them a months dues for anyone they get to show up and try the class - but that is not their revenue model - I refuse to participate in the science experiment, where they get paid and no one shows up.....
I'd stay far away from Yelp, but that's just me. I've heard the usual shady things about them, plus martial arts is pretty far from their usual restaurant-and-bar line of businesses.
