On Wednesday, March 5th from approximately 9am to 2pm PST, some web pages containing the AdWords Conversion Tracking code snippet presented visitors with a browser message indicating a Google server certificate had expired.
This issue has since been fixed. We apologize for any inconvenience that this may have caused.
Please note that conversion tracking data collected during this brief period may under-report the number of actual conversions achieved.
