Jennifer beat me to it by posting at the SEW blog a WebmasterWorld thread named Spying on your competition (requires paid subscription). Basically, when you set up your Google AdWords conversion tracking code, it asks you for an optional "cost of conversion" value. That value is stored in JavaScript, visible to anyone, as;
var google_conversion_value = 15.0;
The 15.0 represents a $15 cost of conversion, entered in by the advertiser.
The cost of conversion value can be attributed to how much a product costs, how much each lead or sale is worth for a company. You can learn a lot about a company with this metric. The question is, why isn't this metric encoded some how? An oversight?
Excellent find and excellent thread, forum discussion at WebmasterWorld (requires paid subscription).
