Fix Pinterest Catalog feed issues

Pinterest Catalog requires google_product_category — it uses Google's published taxonomy directly. Items without it can't enter the catalog. Pinterest is stricter than Google on this; what's optional for Google is required for Pinterest.

Affects: google_product_category

Pinterest can't fetch the image at image_link. Common cause for Pinterest specifically: tall-format requirements (Pinterest prefers 600×900+) combined with thumbnails being served.

Affects: image_link

Pinterest's crawler can't reach the product page. 404, redirect to non-product page, blocked by robots.txt, or HTTPS issues. Items with broken landing pages can't serve as shopping pins.

Affects: link

Pinterest verifies feed prices against landing-page prices. Mismatches block the item from shopping pin distribution. Pinterest's check is slightly more forgiving than Google's but still tight.

Affects: price

Pinterest Catalog requires availability on every item. Without it, the item can't enter the catalog. Pinterest treats missing availability stricter than missing-but-invalid availability — the latter at least makes it into the catalog as 'out of stock'.

Affects: availability

Pinterest Catalog requires brand on every item. Without it, products can't be matched against Pinterest's brand registry and don't serve in branded-pin placements.

Affects: brand

Pinterest expects condition (new, refurbished, used) for catalog items. Missing condition defaults to 'new' in some surfaces but suppresses filterable visibility.

Affects: condition

The product falls under Pinterest's restricted-content policy. Pinterest's policy is stricter than Meta's on some categories (weight loss, body image, financial products, alcohol).

Pinterest requires merchant verification before catalog products can serve as shopping pins. Unverified catalogs can be created but products don't appear in shopping placements.

Item is missing the link field. Pinterest can't surface as a shopping pin without a destination URL. Items with no link don't enter the catalog.

Affects: link

Pinterest can't process the image format. Supports JPG, PNG, WebP — but not GIF (Pinterest treats animated content separately), BMP, or SVG.

Affects: image_link

Pinterest's image policy is stricter than Meta or Google on body imagery, suggestive content, and certain wellness claims. Items with policy-violating imagery don't serve.

Affects: image_link

You've submitted for the Verified Merchant Program but Pinterest hasn't approved yet. Catalog products still serve (if otherwise valid) but without the Verified Merchant badge and associated placement benefits.

Multiple feed rows share the same id. Pinterest keeps the first match and drops the rest. Hidden inventory gap because the dropped rows don't appear in error reports.

Affects: id

Pinterest can't parse the feed XML. Schema validation failed — could be malformed tags, encoding issues, or invalid characters in field values.

Item exists in the catalog but the Shopping Pin feature is disabled — likely because of category restrictions, verification gaps, or trust-signal issues. Items appear as regular pins but without buy functionality.

Item's availability field is set but doesn't specify region-level inventory state. Items targeting multiple regions need per-region availability for accurate placement.

Affects: availability

Feed file exceeds Pinterest's size limits — typically around 1GB uncompressed or 200MB compressed. Items can't sync until file is split.
