I’ve written before about some of the many ways that local businesses spam the yellow pages.
Google Maps has now ‘arrived’. Local businesses are now spamming Google Local (Maps). Surprisingly, many of the techniques that are being used to spam Google, have been used for many years to spam the Yellow Pages.
Mike Blumenthal has several great examples, including my favorite example: 0 & 0 24 Hr Locksmith (and their 1699) listings for a locksmith in Philadelphia (why does the locksmith profession attract spammers?).
While local business spammers won’t have the sophistication of your typical web spammer, what they lack in sophistication, they make up for with sheer numbers.
