Facebook catalogs fail on the same four holes as Merchant Center.

Blank id, empty title, $0 price, no image_link, two rows sharing an id. Commerce Manager uses the same product-data columns. Drop the TSV in the browser. Nothing is uploaded.

How

1. Meta Commerce Manager → Catalog → Data sources → download or export the product file (TSV/CSV with id, title, price, image_link).
2. Open gmc-check.html and drop the file. ShopGaps does not receive it.
3. Fix rows that ads will reject. A ranked Monday list of 20 is the Store Audit (USD $149) — email the same file to info@shopgaps.com.

ShopGaps is not a Meta app and does not connect to Business Manager. TikTok catalogs: tiktok.html. WooCommerce merchants who want an on-site plugin can use Catalog Audit.
