PRODUCT DATA VALIDATION
Validate ecommerce listings against trusted product data.
Product data validation is the practical step of comparing the product information you trust with the title and description you plan to publish. It helps reviewers spot content that no longer matches the product record before a listing goes live.

WHY IT MATTERS
Product data quality should carry through to the listing.
A product record and its published content can drift apart as prices, attributes, and copy change. A material or colour that is correct in one place but contradicted in another makes review harder and gives a publisher less confidence in the listing.
ListingGuard does not decide whether a statement is true in the wider world. It checks the listing against the source values and rules you provide, so the result stays focused on the data available for that review.
Selected source values that do not appear in the listing content
Material, colour, and price claims that conflict with supplied product data
A waterproof claim when the supplied product data does not support it
Missing product name, material, or colour source data
A supplied product name that is not mentioned in the listing
Configured forbidden terms and description-length limits
HOW LISTINGGUARD COMPARES CONTENT
A clear comparison, not an opaque score.
For a single listing, enter the product data you trust alongside its title and description. For a CSV, choose the description column and the source columns you want to compare. ListingGuard then applies its enabled rules and returns passed checks, warnings, or errors with the expected value, listing value where available, and a suggested next step.
1. Provide source data
Use product fields in a single check, or select the source columns from a CSV export.
2. Compare listing content
Check the title and description against selected values and the supported built-in comparisons.
3. Review explainable results
See which rule found the issue and what to change or verify before publication.
Deterministic checks you can inspect.
ListingGuard uses deterministic rules, not AI validation or general fact checking. Its default rules cover required product information, specific forbidden terms, and a description-length limit. You can review and adjust the supported rule types for guest checks in your browser.
