For a specification correction, include the platform, placement, card URL, the value you believe is incorrect, and a direct link to the official documentation that supports the change. Screenshots can help when a requirement appears only inside a signed-in product interface.
Useful Reports
- Data accuracy: Dimensions, ratios, file limits, durations, safe zones or source links that no longer match the platform.
- Missing formats: A current organic or advertising placement not yet represented in the directory.
- Website issues: Broken filters, search results, direct links, templates, dark mode or mobile layout problems.
- Editorial feedback: A guide or tool explanation that is unclear, incomplete or out of date.
What Happens Next
Reports are reviewed against the most direct available source. A suggested correction may not be applied if the source covers a different placement, account type or region, or if the platform documentation is ambiguous. Verification dates indicate when a source was checked; they are not a promise that the platform has not changed since then.
Before Reusing the Data
You may use the directory for creative briefs and production work under the Terms and Conditions. Check the linked source before making a time-sensitive publishing or media-buying decision, and credit the original platform documentation when it is the source of a requirement.
