If you work in eCommerce SEO, make sure you're getting the credit you deserve.
Misattribution is common with free listings within Google Search due to sites misusing old tagging methods within their feeds.
This can apply to features such as product grids, product knowledge panels, the shopping tab, AI Mode, and more. All being organic surfaces that generally have a higher conversion rate compared to non-free listing surfaces.
While auto-tagging within Merchant Center generally does the job for attribution in GA4 (in terms of tracking sales for specific URLs), what can happen is a misuse of the [link] and [mobile_link] attributes being assigned to "google" and "cpc" for all results within the feed itself.
The correct approach should be to use [link] and [mobile_link] for free listings for "google" and "organic" instead. This would mean that the parameters within the example provided would then be attributed to SEO.
Otherwise, it is also completely fine to use the standard autotagging settings within Merchant Center for tracking free listings. With this approach, this traffic is automatically categorised as ‘Organic Shopping’ in GA4, which can be refined even further to ensure the data is clear (such as only filtering by PDPs).
Note: the only downside to enabling auto-tagging is that your standard organic listings will likely start to show with the auto-tagging parameters in search results. This isn’t something to be concerned about from a ranking perspective, but it is a consideration.
If your settings are incorrect, then I would suggest getting this fixed. Clicks on these organic features should be attributed to SEO, not Paid Search activities.
