Remarketing Google Ads

Hello,

I want to launch remarketing campaigns on Google ADS. I followed the tutorial in order to properly configure the parameters for the implementation of the remarketing code using google tag manager.

However, I have a problem that I go to the “Audiences” part of Google Ads, I have a message like:

Fix your audience source that’s sending a required parameter that doesn’t match your feed
Your campaigns can’t tailor dynamic ads based on user activity when the required parameter doesn’t match your feed. Make sure the audience source is sending the required parameter correctly and your feed has the right items.

The values received from your audience source for the required parameter for your business type may be formatted differently than in your feed or missing from your feed. Click “Download” to see the top values received for the required parameter that aren’t matching your feed. Note that Google Analytics refers to parameters for remarketing as Dynamic Attributes. Download

Issue: 100% of ecomm_prodid values received don’t match your feed

Can you help me please ?
