The Huffington Post sold for $315 to AOL this week, and Demand Media recently completed an IPO. In many ways, these events validate the strategy of gaming the system. Google is a beast that can be gamed, and both these operations did it very well.

HuffPo is notorious for hysterical headlines and their lefty slant, but they were also very well organized and filled a void in the marketplace. In many ways they deserve their success. But, a big part of their success has to do with gaming Google’s search results. Their editors find interesting stories, do a post on it with a link back, but HuffPo usually gets all the search traffic. The other sites usually don’t complain, because links from HuffPo provide really good traffic as well.

Demand Media also fills a void, as they use their own algorithm to find potential search results that need to be filled with content. Then they pay know-nothing writers (well, I guess some of them know what they are writing about) to create a short article covering the topic. AOL is even trying to copy the strategy. Many now refer to sites like Demand Media as content mills, and Google might be addressing the issue, but Demand Media has already scored their IPO and Google’s search results are littered with lame content at the top.

Gaming the system pays.

BusinessWeek has a great profile on Henry Blodget and how he’s fighting back with his web properties after his disgraceful exit from Wall Street after the tech bubble burst.

Henry Blodget is a man who will be neither easily riled nor insulted. When, in March, he learned that a blog had labeled a section of The Business Insider, the gossipy financial website he founded three years ago, “The Hooters of the Internet,” Blodget waited a couple hours before tweeting: “The Hooters of the Internet. I like that.” In May, Blodget predicted on his website that within just a few years, The Huffington Post will take in over $100 million in advertising revenue—more than triple the $30 million the site says it will bring in in 2010—and that by 2015 or so, it would be generating more from advertising than The New York Times. In an endnote, he disclosed that Kenneth Lerer, a co-founder of The Huffington Post, is also an investor in The Business Insider, or TBI as it is known by its readers. “Thank you for the disclosure,” someone called The Truth typed in the piece’s comments section. “Unfortunately, it invalidates everything you write. You’re a mouthpiece.” It took Blodget less than a minute to post his response: “Thank you!,” he wrote, like a fraternity pledge embracing his hazing.

Blodget was busted back then by then-New York Attorney General Eliot Spitzer, who has since had his own problems. Spitzer now has a TV show premiering soon on CNN, so it looks like everyone can get a second chance.

The Business Insider, along with niche areas like Silicon Alley Insider, is an excellent online magazine and news resource, so Blodget appears to be on his way.

I agree that HuffPo will keep growing as well, though at some point they might want to scale back those ridiculous and often misleading headlines.
