Where do you have your links pointed to in your google ads? Your home page? Other pages within your web site? Both? Is Urchin collecting the data on the same pages that you have your Google ads pointing to? With our analytic tool (we don't use log files to track your traffic), we actaully put a piece of javascript on each of your web site's pages that will collect the data from the incoming Google url.

To do this: we set up a tracking string at the end of your Google destination URLs that point to your web site. Then we set up that same tracking string within our tool, so that when somebody clicks on your google ad, we'll be able to pick up all of the info.

But if you had a google url pointing to a page on your site that didn't have our code on it, we wouldn't be able to pick up the referring keyword.

Did this help or did I confuse you?
