Reporting a Data Error
A precise report is the quickest to check. Please include:
- The page address (URL) where you saw the error.
- What is wrong, quoted or described exactly.
- What it should say, with a public source that shows it.
- When you saw it, since rankings change with each daily snapshot.
On a use-case page, the Report a Problem form sends the page reference for you.
Reporting an Accessibility Barrier
We aim for WCAG 2.2 level AA. If something blocks you, please tell us:
- The page address and what you were trying to do.
- What happened instead, and where on the page.
- Your browser and device, and any assistive technology or zoom level you use.
- Any workaround you found, if one helped.
Writing to Us Safely
- Include only what is needed to answer you.
- Never send passwords, access tokens, payment details or identity documents. We will never ask for them.
- Leave out other people’s personal data unless the request is about it.
- For a deletion request, say which data you mean, for example the address you used for a newsletter sign-up.
