I am using a PMAX campaign with google shopping. The item id is patkit. It is the same both in my shopping cart and in my google merchant. When a user adds an item to cart, snip cart sends an add_to_cart event to analytics/adwords, but there seem to be a problem with the product id.
Specifically, Audience sources > Google Ads tag > Retail reports 0 Tag hits with feed key matching a servable feed item. This has been going on for more than 1 month. I have tried everything I can think of. I fear my campaign is wasting money because it is unable to properly connect merchant to remarking via max.
I am including a screenshot of what I see in my google account.
My snipcart code is:
<button type="button" class="btn btn-warning btn-raised shadow btn-sm snipcart-add-item"
data-item-id="patkit"
data-item-price="{{.Site.Params.patkit}}"
data-item-name="PATKIT"
data-item-shippable="true"
data-item-stackable="never"
data-item-url="{{ .Page.Permalink }}"
>
<span class="glyphicon glyphicon-shopping-cart"></span>
Add Kit to Cart
</button>
