Look, I know that being ranked 28 is pretty much near invisible in terms of traffic you’ll get from search engines. But then again, to go from nowhere to the 28th top page in Google out of 755,000 matches? I’m sorry — don’t tell me that being in Knol doesn’t give your page some authority. Yes, I understand that individual backlinks will likely make the difference in how high you rank for a particular term. But the bottom line is that Knol feels like a trusted domain to Google, and content hosted on trusted domains will do better, in my opinion.
