If you're reading this then you likely saw a message similar to this in your AdWords account:

Or worse a warning:

This usually comes down to two things:

  1. You have the Custom ID parameter source setup which uses "Item ID" (not to be confused with ecomm_prodid)
  2. You don't have products on every page of the site and thus are not sending ecomm_prodid on every pageview hit event.

Check for Custom ID Parameter Setup

Inside of AdWords go to your Audience Sources > Audiences > AdWords > and then click into the Item ID error like this:

Once here, check to see if you have the Custom ID parameter checked and then you'll see the Item ID is actually the dynx_itemid:

Since you're a retail store we are using the proper parameters - Retail - and sending these via ecomm_prodid shown just above the custom parameters. 

If you have the custom parameter setup and aren't sure why - it could come from a # of sources such as previous apps, developers, agencies, team members etc. 

You can't remove this setting so you'll have to wait for this false positive message to go away on its own.

ecomm_prodid is not on every page of site

We believe in most cases this is a false positive if you've set up our app in its entirety and you do not have products on every page of your site that require this to be 100% of pageviews are sending ecomm_prodid's. 

Why do we believe a false positive?

According to Google's own requirements found here only PRODUCT and CART pages should send the ecomm_prodid in the remarketing tags:

Which is exactly how our tags are created. 

And since you're an eComm site then you have many other pages that users view (home, collection, search etc) which would take up a large % of event hits.

So as long as you see some ecomm_prodid data in the graphs below this main warning message like this:

Then you are likely OK.
