No, it's just a website of mine that indexes quickly. But again, this was more of an experiment to see what was possible. For a keyword worth anything, it's never been anywhere near that fast for me. Not even close. But I have seen some keywords (relatively low search volume) appear in the Top 30 range in just a couple days when the competition is low enough and Google feels like being nice to me. Most of the time, however, I'm pushing out too much content to really notice. I don't typically pay attention to these sorts of things like I once did, as it seems Google has been changing things. I think Google has a stronger focus on relevancy and so keyword rankings for me are coming and going, mostly. Many stick around, but quite a few pop in and pop out, seemingly at will. Google knows what it's doing, and while I may not understand entirely, I just focus on publishing really good content.
