Everything reaches the same place: [email protected]. There is no contact form on this site, deliberately, because a form would collect data the privacy policy promises not to collect.
Corrections and factual disputes
These get priority over everything else. If a figure here is wrong or has moved since it was checked, say which page and which sentence, and point to the source that supersedes it. A network correcting its own entry is treated exactly like a reader correcting it, and the same evidence standard applies to both — the tiers are set out in the review methodology. Confirmed errors are fixed and the page's review date is updated, following the process in the editorial policy.
Networks and platforms
Advertising networks are welcome to submit updated deposit minimums, payment terms, format lists and documentation links. Send the platform page or advertiser documentation that states the figure rather than a summary of it. What cannot be arranged: a position in a comparison table, a review in exchange for a commercial relationship, or sight of a draft before publication. Those are ruled out by the affiliate disclosure and the independence rules behind it.
Press, research and republication
Quoting a passage with attribution and a link needs no permission. Republishing a full article does. Requests to reproduce the native ads reference in whole or in part, and interview or comment requests, go to the same address; the conditions are on the terms of use page.
What to expect
Mail is read by Christoph Trappe, who also writes the pages, so a reply comes from the person responsible rather than from a queue. Corrections are usually acknowledged within a few working days. Sales pitches, link exchange offers and guest post proposals are not answered, and the reasons are on the about page.
