Some advertisers are reporting issues with Google Ads’ GCLID (Google Click Identifier) offline conversion uploads, starting on Sept. 12.
Although uploads are marked as successful, the associated conversion actions are showing zero results.
Why we care. Conversion data is the backbone of measuring campaign effectiveness. Without accurate tracking, it’s impossible to assess ROI, optimize bids, or make informed decisions on ad spend.
Driving the news: Multiple advertisers, including Benjamin Wenner and Josiah Daves, flagged the issue on X, noting missing conversion data across several accounts. Daves reported that more than 250 of their accounts have been affected, with conversions dropping off after 2 p.m. EST on September 12.
