5600+ hits on a review about applying for visas - I doubt that anyone would have predicted that.
4700+ on a restaurant; 4300 on a beauty product; 4000+ on a cinema scheme.
Those are my top ones and they don't fit the 'cars and household products' type cats that have been suggested.
Mind you, it's also possible to get on the first page of a google search with a small number of hits. I'm on a mission to publicise that crap service I got at a hotel and already both the dooyoo and ciao reviews are coming up on google searches AHEAD of the hotel's own website. Hoorah! That'll teach the bastards (until they threaten to sue dooyoo and Ciao!).
