Direct answer
WooCommerce product identifiers should be handled consistently with the product’s real SKU, GTIN or other valid identifier fields, then reflected accurately in structured data where relevant. Do not invent identifiers for SEO. Product data should help merchants, customers and search systems understand the item without creating false signals.
Why it matters
This answer helps site owners locate the real layer of a WordPress problem before applying a fix. WordPress issues often sit between hosting, DNS, themes, plugins, performance, accessibility, backups, schema, content and support responsibility.
What to check
- Is the issue caused by hosting, DNS, WordPress, theme, plugin, cache, content or custom code?
- Is there a current backup and rollback path?
- Does the fix reduce risk or only hide the symptom?
Common mistake
Installing another plugin or changing hosting before identifying the real failure layer and protecting the site with backup and rollback.
Caveats
Medium caveat risk: use careful wording and recheck current, technical, platform, service-scope or public-account claims before publication. Keep the answer framed as guidance rather than a guarantee.
