Ads Link to Error Pages

When you activate Analytics within AdWords, Destination URL auto-tagging is turned on automatically. This feature allows Analytics to track information about clicks on your AdWords ads by tagging your AdWords keyword destination URLs with a gclid= parameter. This parameter is displayed in your landing page URL. For example,

A small number of websites do not allow URL parameters, and consequently serve an error 404 page when a URL contains those parameters. If your site does not allow URL parameters, you can lobby your webmaster to allow them, or you can turn off auto-tagging.

To turn off auto-tagging:

  1. Sign in to your AdWords account at
  2. Click the My account tab, then select Account preferences.
  3. In the Tracking section, click Edit.
  4. Clear the Destination URL Auto-tagging checkbox.
  5. Click Save changes.
