Reminder: Important changes to the Google Click ID (GCLID) character length

In February, we announced important improvements that will change the length of the Google Click ID (GCLID) values ( Beginning March 31, 2014, we increased the character count for GCLIDs from 26 characters, to range in length from 25 characters to a maximum of 100 characters. 

Depending on how your team captures and stores the GCLID values, this change in length might require some script and schema changes. We recommend that you share these changes with your team as soon as possible so they can determine if they need to update any of their systems.

For more details on this change, please see the detailed blog post ( from our AdWords API team.
