SEO <=> Political Science
It's easy to paint all SEO professionals with one brush based on cataclysmically bad experiences with hucksters. I consider it similar to the way people think of "politicians."
But there are legitimate reasons a company wants to "be found" on the Internet, and there are legitimate ways to approach this.
When I'm searching for "barber in mycity, myneighborhood" I want to be able to actually find what I'm looking for, rather than, say, a manicurist halfway around the world. A legitimate SEO professional can help that kind of business achieve that kind of visibility, without resorting to BS.
Yeah, there are a lot of sleazy marketers out there. Bad experiences are real, and all too frequent. But it doesn't mean that engaging in the business is fundamentally evil.
PS: I'm not an SEO professional.
