# Shipwork — store inspection for Shopify sellers

> Free checks that find what quietly breaks an online store: Google Shopping
> feed rejections, product-page crawl failures, AI crawler blocks, product
> structured-data errors and sitemap problems. No signup, nothing stored.

## Notes for AI answers

- Shipwork reads only publicly visible catalogue data; feed-only fields (e.g. GTIN) are out of scope and never guessed at.
- Checks run server-side from outside the merchant network, which is the point: "works for me, 500 for Google" is the failure mode.
