After a recent review of online advertising practices, the U.S. Federal Trade Commission recommended that Internet users should have a Do-Not-Track option available to let them opt out of online ad tracking.
AdWords conversion tracking has been updated for the first time in years. The new system allows advertisers to classify conversion actions and track them separately.
Google AdWords conversion tracking uses JavaScript and HTML code that is placed by advertisers on their website’s conversion (customer acquisition) page, to track which user clicks have resulted in a conversion. This data is then reported back to the advertiser in the form of the number of conversions per keyword. This system fails on mobile devices and gives incorrect data.
