TierUp Feed Doctor

Understand Google Merchant Center rejections. Fix the cause.

Feed Doctor diagnoses common product-data and landing-page issues behind Google Merchant Center disapprovals. It explains each cause and applies only the safe fixes you approve, with AI used only when rules are not enough.

The problem

Feed tools generate feeds. They don't fix rejections.

Disapproved products pile up in Google Merchant Center. Every rejected item is a product nobody sees in Shopping, and no feed generator solves that for you.

Missing GTIN

Without a GTIN/brand the item is rejected. Feed Doctor spots the gap and suggests the correct identifier.

Wrong category

A mis-mapped Google product category drags down entire product groups. We map it correctly, with AI when needed.

Price ↔ landing page

If the feed price differs from the price on the page, Google rejects it. We find the mismatches before Google does.

Drafts & policy

Draft products leaking into the feed, and risky promotional claims (policy): flagged and cleaned up.

How it works

Feed in, clean feed out.

Three steps. No account required, no theme changes. Feed Doctor works from a feed file, whatever store system you're on.

01

Upload feed

Upload your product feed (Shopify, WooCommerce, Etsy, any file). It stays a file: no store connection, no token.

02

Diagnosis by reason

Feed Doctor groups every rejection by cause (GTIN, category, price mismatch, drafts, policy) so you see the pattern, not just isolated errors.

03

Download corrected feed

One click, and you download the corrected feed, ready for Merchant Center.

AI last: Most fixes are deterministic, so they're fast and cheap. AI only kicks in where rules aren't enough (e.g. category mapping for a messy catalog).

Why us

From rejection reason to a clear next step.

Feed Doctor focuses on diagnosis, explainable fixes and merchant approval.

Cause, not just symptom

Each finding is grouped by its likely cause, so you can review the relevant products and decide the right correction.

Compliance-aware checks

Checks can flag fields related to EU selling requirements, but they are not legal advice and still require merchant review.

Your data can stay in the EU

On request, processing stays in the EU. In basic operation the feed is just a file: no store connection, no data leak.

Platform-agnostic

Shopify, WooCommerce, Etsy or a custom export: Feed Doctor works from the file and isn't tied to any store system.
