Three surfaces describe the same product: the ad, the page, and the feed.
They are often owned by three people, updated on three schedules, and optimized for three goals. The product ends up with three identities.
The hard failures
Price, availability, currency, structured data, and variant selection must agree across surfaces or products can be disapproved.
The soft failures
Promo language stays in the ad, titles are optimized for the wrong system, variant names diverge, and collection renames never propagate.
Feed titles are not SEO titles
Your PDP title and feed title serve different systems. Supplemental feeds let you keep storefront titles while writing ad-facing titles for shopping intent.
The consistency checklist
- Price
- Availability
- Variant
- Title
- Offer language
- Currency and language
Decide where truth lives for each field, then make every other surface read from it.
