Well, my rankings don't really fluctuate - but clearly others do, and I know there's some weird stuff that gets thrown up into the serps sometimes. This is one of the weirdest examples I've seen to date. I've seen this stuff before, but this is on a competitive term - a trophy term. And it's ranking like #2. It's beating my site.
Possibly the affiliate has thrown a bunch of backlinks at that page that's causing it to rank. Certainly the blog owner hasn't done that. And I doubt it's ranking due to any type of user experience measurement, the article is actually garbage, a step above a poorly spun article.
