Field notes on ad fraud, MCM, and the economics of publisher monetization.
One in five ad impressions is fake. Here is the machinery behind the biggest invisible tax on the open web — and why it is not going away.
Time zones, currency, gross-versus-net, unfilled impressions, IVT deductions and overdelivery. Every line of the difference between what your dashboard says and what arrives.
AI crawler traffic grew fourfold in eight months while referral traffic back stayed near zero. What it costs you, why your analytics are lying, and the reframe from cost to line item.
Synthetic Echo, DreamScheme and Papyrus: three schemes that stopped hiding from measurement and started gaming it, until the fraud outperformed legitimate inventory on every dashboard.
A file at yoursite.com/ads.txt proves who may sell your inventory — and is only as honest as the chain behind it. What the standard does, what it cannot do, and how both get exploited.
The clause in Google's Partner Guidelines that keeps MCM operators awake: the parent carries liability for its children's inventory, including for things neither of them did.
The fraud that is not technically fraud. Why MFA defeats every tool buyers rely on, what the arbitrage arithmetic actually looks like, and where aggressive publishing ends and MFA begins.
One fires millions of clicks and hopes. One fires a single click at exactly the right millisecond. One skips clicks entirely and forges the payload. Telling them apart is the whole job.
Ten operations, six years, and one repeating pattern: every takedown produces a more distributed sequel. What Methbot, VASTFLUX and BADBOX 2.0 each taught us.
Appeal success on invalid traffic is reported under 10%. The three enforcement stages, the behavioural signals that trigger them, and the practical work that lowers your risk.
