Years ago, when there was first talk of how any business could make a go of it against the big guys online, there was a saying that went something like this: "on the web, no one knows you're a dog." The point was that even a small niche shop in the middle of nowhere could compete with a mega-store like Sears or Wal-mart. That's still true and in some ways, the search engine marketing world is a great example.

Search engine marketing firms of all types and sizes bid on projects that range from the corner market to Fortune 100 firms on every day. Projects are handled in lofts in NYC and in homes in India. There's also been a bit shift lately toward SEM firms partnering up with more traditional advertising and media firms in order to reach larger clients (and for the agencies to be able to fulfill the requests without taking on internal staff.)
