Christoph Trappe is a content strategist and author who has spent more than a decade advising brands on how to publish material people actually want. He was named to the Content Marketing Institute's Top 100 Content Marketers list and was recognised as Internet Marketer of the Year by the Internet Marketing Association in 2015. He founded the Authentic Storytelling Project and hosts the Business Storytelling Podcast.
What he covers here
The push ads guide is his work: the definition of the format, the RFC 8030 delivery chain, the difference between classic and in-page push, why iOS barely appears in push inventory, what Chrome's 2025 enforcement did to subscriber bases, and what the traffic costs across eight networks. He also wrote the pricing comparison and the campaign troubleshooting table on that page.
How he approaches the subject
His background is content strategy rather than media buying, and that shapes the guide in a specific way. The recurring question in his work is whether a piece of content earns the attention it interrupts — which turns out to be the exact question a push ad raises, since the format's entire value proposition is interruption. Chrome's spam classifier reading notification titles is that question enforced in code.
It also shapes what he will not write. Estimated CPCs, invented test results and unattributed benchmarks are absent from this site because a claim you cannot check is worth less than no claim. Where a number needed a live campaign to verify, the guide says so and stops. The review methodology spells out that boundary.
Sources and corrections
Technical claims here trace to Chromium, WebKit, Mozilla, the IETF and the W3C rather than to ad network blogs, and every dated figure carries its date. That standard is set out in the editorial policy, which also describes how corrections are handled and how quickly.

His work outside this site spans content strategy consulting, speaking and the Business Storytelling Podcast. Facebook and Instagram, linked above, are the accounts verified as his and are the ones referenced in this site's structured data.
The about page explains why push-ads.io publishes one guide properly instead of forty thinly, and the terms of use state the limits of what any of it guarantees. Data handling on the site is covered by the privacy policy.
