How it works

Merchant Center feed audit in three steps

No spreadsheets, no manual checks. Paste your feed URL and get a complete health report in under a minute.

1. Paste your feed URL
Enter the public URL of your Google Merchant Center product feed — XML, TSV, or CSV, up to 200 MB. The same URL you submit to Merchant Center works here.
2. We analyse every product
The engine streams your feed in a single pass and runs 40+ checks across required attributes, title quality, GTIN checksums, variant groups, and structural integrity.
3. Get your scored report
You receive a 0–100 quality score, an A–F grade, a breakdown by severity (Blocker / Major / Minor / Opportunity), and per-product fix recommendations you can act on immediately.
What the audit covers

Six layers of Merchant Center feed health

A single streaming pass over your product feed audits every dimension that affects Google Shopping eligibility, approval status, and ad performance.

Required Attribute Coverage
Measures coverage across all 7 required and 11 conditional Merchant Center attributes. Products missing title, image_link, or availability are flagged as Blockers that cause disapprovals.
Title & Description Quality
Checks title length against the recommended 70-150 character range, flags titles under 30 characters as critical, marks the 30-69 band as weak and worth improving, and treats titles above 150 characters as low-priority notices because they may be truncated. It also reviews titles and descriptions for excessive capitalisation, keyword stuffing, missing copy, and policy-heavy text that can hurt Shopping performance.
GTIN & Identifier Validation
Validates UPC, EAN, ISBN, and GTIN-14 check digits using the GS1 algorithm. Rejects all-zero GTINs and coupon barcodes (prefix 98/99). Also catches missing or placeholder brand values that prevent Merchant Center approval.
Variant Group Integrity
Checks that variants sharing an item_group_id are differentiated by at least one standard axis (color, size, material, pattern, gender, age_group) and flags single-member groups, duplicate IDs, and undifferentiated variants.
Feed Structural Integrity
Detects duplicate product IDs, empty feeds, invalid availability values, malformed price formats, and URL errors — all of which prevent Google from parsing your Merchant Center feed correctly.
Enrichment Opportunities
Surfaces optional attributes — custom_label_0–4, product_type, google_product_category, and additional_image_link — that improve PMax campaign segmentation and Shopping ad relevance without triggering disapprovals.
FAQ

Frequently asked questions

Everything you need to know about Google Shopping feed audits and Merchant Center feed errors.

What is a Google Shopping feed audit? ›

A Google Shopping feed audit is an automated analysis of your Merchant Center product feed that checks every product for required attributes, format errors, title and description quality issues, invalid GTINs, and variant integrity problems. The audit assigns a quality score from 0–100 and a letter grade (A–F) so you can prioritise fixes that prevent product disapprovals and improve Shopping ad performance.

Which attributes does Google require in a Merchant Center product feed? ›

Google requires seven core attributes in every product feed: id, title, description, link, image_link, price, and availability. Additional attributes become required depending on product type: brand and gtin (or mpn) are required for most products; condition for used or refurbished items; gender and age_group for apparel. Missing any required attribute causes the product to be disapproved or receive limited impressions.

What does the A to F feed quality grade mean? ›

The feed quality grade summarises your overall score on a 0–100 scale: A (90+ with ≤2 major issues) means your feed is healthy; B (80+) is good but has room for improvement; C (70+) indicates noticeable gaps; D (60+) means significant problems are limiting performance; F (below 60, or any blocker present) means the feed has critical errors likely causing disapprovals. Blockers such as an invalid GTIN checksum, a missing required attribute, or a malformed availability value always result in an F grade.

What causes products to be disapproved in Google Merchant Center? ›

The most common feed quality and Merchant Center approval issues are: an invalid GTIN (wrong check digit or all-zero value), missing required attributes (title, link, image_link, price, availability), an invalid availability value (must be exactly in_stock, out_of_stock, preorder, or backorder), a price of 0.00, titles under 30 characters, titles in the weaker 30-69 character band, and a landing page that does not match the feed data. Titles above 150 characters are still surfaced as notices because they may be truncated. The Adsage feed audit surfaces these with the exact attribute name and a recommended fix.

How does GTIN validation work? ›

GTIN validation verifies the numeric check digit of each Global Trade Item Number (UPC, EAN, ISBN, or GTIN-14) using the standard GS1 Luhn-style algorithm. The audit also rejects all-zero GTINs and coupon barcodes (prefix 98/99) that are invalid for Shopping use. An invalid GTIN is a Blocker-severity issue and results in product disapproval in Merchant Center.

Which feed formats does the audit tool support? ›

The Adsage feed audit supports all three Merchant Center feed formats: XML (Google's standard Shopping feed schema), TSV (tab-separated values), and CSV (comma-separated values). The format is auto-detected from the URL or file content. Feeds up to 200 MB are supported, and the tool streams the feed in a single pass to handle large catalogs efficiently.

Is the feed audit free? Do I need to create an account? ›

Yes, the Google Shopping feed audit is completely free and requires no login or account. Paste your public feed URL and click Audit My Feed — your feed data is not stored after the audit session ends. For ongoing performance analysis that connects Google Ads spend, Merchant Center, and GA4 revenue data to identify which products waste budget or hide revenue potential, Adsage offers a free dashboard tier with no credit card required.
