Data, reconciliation & reportingClient work
One product ID across Merchant Center, GA4/Ads and Meta so catalog ads match your products — plus the feed fixes behind them.
Sounds familiar?
How I solve it
I build one product identity across every system: the Shopify variant ID becomes the master, and I carry it through Merchant Center offer IDs, GA4 and Google Ads item_id, and the Meta catalogue’s content_id and the pixel’s content_ids. Then I clean the catalogue so archived, draft and duplicate products stop feeding the feed. I finish by measuring tracking quality before and after against your real orders, so the fix is proven, not asserted. Approval decisions stay with Google and Meta; I fix the technical side and say plainly when a problem is policy and not data.

A note from Daniilbefore you decide
If you sell on one platform and the IDs already match, there is nothing to align. And if your products are disapproved for a policy reason, no ID change fixes that — I will tell you it is the platform’s decision and not sell you a data fix.

Questions
The Shopify variant ID. It is the most granular, it exists for every product, and it can be carried into every platform's field.
Because the catalogue and the pixel never meet on the same product. The platform is shown one product in the feed and a different one in the event.
Not necessarily. Approval belongs to the platform. I fix the technical setup and state in writing that the decision is theirs.
Usually a collaborator role on Merchant Center plus read access to Google Ads and Meta is enough. Read-only is enough for a diagnosis.
Before and after, measured against your real orders — the same way the 29% → 80% figure above was read.
