A feature that automatically adds a parameter to your URLs to help you track offline conversions and report on your ad performance using website tracking programs like Google Analytics.
- Auto-tagging will attach the “Google Click Identifier” (GCLID) parameter to the URL your customers click, and that will help you tell which ad was clicked for each visit to your site.
- Google Analytics and similar programs can use the information from auto-tagged URLs to tell you which AdWords keywords brought a visitor to your site, which campaign that keyword was from, and how much that click cost. You can also use this information to import complex conversions into AdWords, whether online or offline.
If you use an API, the GCLID parameter can also send more information from each click to the Click Performance report of the AdWords API.
