Random SEO success

In November, I put some tools written in JavaScript on here. These are mostly conversion tools, things like pounds to kilograms, kilometers to miles, etc.

I had the idea of coding and hosting some random JavaScript things on here, but since then I haven't added anything.

Then I forgot about them.

Now, I get most of my traffic on these conversion tools. As of recently, if you search millimeters to inches on Yahoo!, my site is #1. Because of this, I've gotten a whack of traffic just on this one page.

I wonder what it is about that page that Yahoo! considers so special. There aren't even any sites that link to it. It's really some kind of SEO marvel.
