What to include
- Wrong data: the exact page URL, the figure you believe is wrong, and the source you are comparing against. Corrections are usually applied within a few days.
- Bugs: the tool name, what you entered, what you expected and what the page returned. A screenshot helps.
- Removal requests: data or content you believe should not be published, with the URL and the legal basis for the request.
- Advertising and partnerships: the site name and the format you have in mind.
