Corrections, questions about our method, and press or partnership enquiries.
One address reaches the editor. We answer corrections first, then reader questions, then everything else.
Reporting a correction
Include the page URL, the sentence or figure you believe is wrong, and if you have one, the source that contradicts it. Corrections that come with a source get fixed fastest, and the correction is noted on the page.
Something broken
If a link leads nowhere, a table fails to display, or a page is unreachable, tell us the URL and what you saw. Commercial outbound links pass through a redirect page on this site; if that page tells you a destination is not approved, the link was likely mistyped or has since been removed from our list.
What we do not accept
- Paid placements, sponsored posts or bought conclusions
- Guest posts carrying commercial links
- Link insertion requests
Affiliate partnerships are handled separately and are not a route to editorial coverage.
