Conversion Tracking Broken?

[luke175]

So I'm giving conversion tracking another go...

Anyone else find it totally worthless?

I sell a downloadable software product so I know people have to hit the page with the tracking code on it to get their product.

I use MSN and Overture and their conversion numbers always match mine.

Yesterday, 7 Google sales but conversion tracking shows only 2.

This happens almost every day with Google.

Anyone else see this?

I see it a lot when initial user entry to my site is from AdWords, but the user does not convert until after they start another browser session, perhaps with a different IP address being assigned by their ISP, or the next day, after the user has browsed the site awhile, maybe saved or printed a product page to show the spouse, and then comes back to convert, starting with a saved url or from the home page.
