Ad-fraud / click-tracker test page
A self-served ad unit + click-tracker URL. Clicking the ad fires a request to /ad/click, which 302-redirects to / — the shape real click trackers use (302 to the advertiser's landing URL). No real ad network is paid; no advertiser is harmed.
(routes through /ad/click tracker)
An ad impression beacon would normally fire here on page-load. The click link fires a GET to /ad/click?….
Programmatic click test
To simulate ad-fraud through an intermediary: load this page through it, then fire the click URL N times. Each click returns a 302 to / (real click trackers redirect to the advertiser's landing). The sink records each click in the server's request log with the request's IP and headers.
GET /ad/click?creative=<ID>&placement=<slot>&campaign=<name>
Note on real AdSense
A future iteration could embed a real Google AdSense unit on this page. That would test against Google's IVT (Invalid Traffic) detection — the same anti-fraud system that protects real advertisers. Wiring this up requires AdSense publisher approval for the domain. Not enabled here.
