I have a new campaign that has the conversion code placed on the confirmation page, I'm only seeing about 1/10th of the actual leads generated by google... Any ideas why it would be so far off?
Maybe your other leads are coming from organic results? Remember that the conversion shows for the ad and keyword on the date the visitor clicked on your ad. So if I clicked your ad last week but bought only today, the conversion is shown on the ad I clicked last week. It won't show a conversion today. Maybe that's partly the source of your confusion.
might be you are getting few sales from adwords ads, and few from direct website landing or organic search result
