What MerchantPreflight does well
It packages store readiness into one place: a misrepresentation checker, a policy checker and builder, a product-feed checker and a product-page auditor, with saved reports. If you want a guided Merchant Center readiness workflow, that is the value.
Where it stops
It is a paid subscription and focused on Merchant Center readiness, so it does not cover the general SEO surface — indexation, canonicals, structured data, AI crawler access, TLS and DNS — and it does not run on a schedule to tell you what changed.
What Shipwork does instead
- Free and account-free for every check, including the feed-file check.
- The full technical surface: indexation, canonicals, structured data, sitemaps, AI crawlers, TLS, DNS and email auth.
- A feed-file check (CSV, TSV, XML) for GTIN, category, condition and identifiers.
- A daily watch that emails you the day a check changes.
Which should you use?
Use MerchantPreflight if you want a paid, guided readiness workflow with saved reports. Use Shipwork for the free checks, the wider technical surface, and to watch a store over time.
