To repeat what is in the posted link above:
This is an issue with Shopify's Google Shopping Channel: When the Shopify App uploads the product feed to Google Merchant Center, it appends the following UTM tags to the product url:
You can confirm this by going to your Merchant Center > Products > All Products > and click on one of your products that was uploaded via the API. Look at the product url / link and you will see the utm tags in there.
To remove the UTM tags using Feed Rules:
Hope that helps!
The paid & organic report (available for Google Ads engine accounts only) shows the search terms that either triggered your ads to appear on Google, triggered Google to display unpaid (organic) search results for your site, or both. This information helps you understand how paid and organic search work together to reach people searching online.
To add a big more to this topic:
After digging into it some more, I've come to these additional conclusions:
If you use tracking parameters in your link attributes, it is recommend that you use the canonical_link attribute to provide a canonical URL. Use the canonical_link attribute to ensure that products are associated with the correct URL in the Google Search index.
Does this cause the mixing of paid/free google shopping?
If I strip out those paramaters (sag_organic, product_sync. . .) - will auto-tagging then start acting as I would expect? (Paid ads would show as google/cpc)
@Czarto unless I am wrong, stripping out all the parameters would actually prevent Google from seeing them, no? I tested the changes on Merchant Center and nothing would be seen aside from the remaining parameters (including currency). I have tested @Endlesslearning solution and it seems to work for what I need to do. (Mostly see which ad is generating a sale via Shopify + Google Analytics) I am personally using "Content API.title"
@Puda Google Analytics can usually properly categorize stuff without the need of explicit UTM tags, in particular for "search" traffic. Any Shopping traffic coming from Google Ads (paid) will be properly categorized due to GCID being passed (UNLESS your GA account is set to allow UTM tags to override GCID parameters). Any untagged organic Shopping traffic will be categorized in whatever way GA decides (I **assume** as organic search, but I'm not sure).
I don't think there's a single "right" way to do this, so if you're implementation works for you, then that's probably good enough!
The same happens to me.
I mean I got a purchase from Sag_organic, and I wonder if it is the result of any of my google campaigns or not?
I am only running google campaigns at the moment
Nope, it would be from the free listings. However, they can only happen if you have a feed set up already. I count the free listings as overall paid efforts. Same with Buy on Google sales.
