I have 2 Google Shopping Ads Campaign for 2 counties: AUS, UK.
Aus data is correct: Google Ads shows the clicks is like 99, Shopify shows 105 from Aus. Thats no problem.
But UK data is significantly different. Google Ads shows the clicks is 97, But, Shopify only shows 17 UK customer sessions?
Other infomation:
1)GA4 data is similar with Shopify (GA4 also indicates UK session is low).
2)Before October 4, everything was normal. The data from Google Ads and other sources was accurate. However, starting on October 4, the data began to become anomalous. On October 5, traffic from the UK was halved. On October 6, traffic continued to decline sharply. Until now, there seems to be almost no traffic, but Google Ads still shows clicks.
