Google Adwords offers some of the best conversion tracking, if not the best conversion tracking, in the world. But guess what? Most businesses advertising on Adwords are NOT using it. They don't know how well their ads are performing on a campaign level, nor an ad group level, nor an ad level, nor a keyword level. All they know is clicks - but setting up conversion tracking will enable Adwords to tell you exactly which campaigns and which ad groups and which ads and which keywords are actually becomes leads or sales. I confess that I spent thousands on Google Adwords without conversion tracking, but now I wouldn't spend another dollar without it. I gotta give credit to Simon for helping me out with it, he can help you too if you call his phone during business hours, his number is 256-398-3835.
