20 cities is hardly "every city". I tried 'frrole.com/mycity', expecting a page to be generated on the fly, but no such luck. Should be possible though, and then you could legitimately state that you offer results for every city.

It would also be a nice touch to use geolocation to automagically generate a city (or region) page. Right now, it presented me with the page for Mumbai, while I'm in Europe. Out of the available options on the site, London is closest to me.
