The issue. Impressions and spend have dropped in Smart Shopping for many UK advertisers starting around August 20, 2021. “A high proportion of UK-based advertisers have seen a drop in impressions, cost and revenue for their PLA campaigns since Friday 20th,” tweeted PPCer Liam Wade. Google Ads Platinum Product Expert Emmanuel Flossie posted in the forums that it’s a known issue.

Update: “Our team uncovered a technical issue that prevented some products from being served via Shopping Ads, since 8/20. As a result, corresponding impressions & clicks may have been impacted. The issue is now completely resolved as of 8/24,” tweeted Google Ads liaison Ginny Marvin on Tuesday afternoon.

Some seeing returns to normal. While advertisers initially saw drops as high as 70% to 90%, some are seeing a return to normal in the past week. Wade reported a 75% increase in impressions from the dropped numbers previously.

Why we care. “Assuming it gets fixed, bear in mind that bid strategies will likely be affected and may re-enter learning phases,” tweeted Wade in the initial thread. If your accounts or campaigns have been affected by this issue, it’s critical to communicate to clients and stakeholders that this change is a glitch in their metrics, and not indicative of other issues. It’d also be beneficial to annotate this change in Google Analytics so any KPIs can be caveated in future reports. The bug is also causing advertisers to question the machine learning and automation happening behind the scenes in ads.

This report will continue to be updated as we gather more information.
