About AdSentry — Ad QA Inspector

AdSentry is an ad-QA inspector for publishers, ad-ops teams, and agencies. Broken ad slots quietly cost real money — AdSentry surfaces the bugs so you can fix them before they eat your revenue. It attaches a live monitor in the page at load time and hooks real Google Publisher Tag events, so it can tell the difference between an ad that filled, returned a no-fill, refreshed, or duplicated — something a simple DOM scan can't do. WHAT IT DETECTS • Ad slots via Google Ad Manager (GPT) and DOM ad containers • Load state per slot: filled / no-fill / rendered / refreshed • Runaway or missing refresh on infinite-scroll feeds • Duplicate ad slot IDs • Targeting key-values (KVPs) sent on each ad call — slot-level, page-level (including googletag.setConfig), Prebid hb_* keys, and AdGrid • Ads loading on sponsored / advertorial pages • Connatix on non-article/video pages • Ad-attributed layout shift (CLS) • Ad tech present: GPT/Ad Manager, Freestar, AdGrid, Prebid.js, Connatix, Taboola, Outbrain, AdSense, Amazon TAM, GTM, GA4 WHERE YOU SEE IT • Toolbar popup — QA score, issues, slot summary, exports • DevTools “AdSentry” panel — live, sortable slot table + streaming event log, click any row to see the KVPs sent on that ad call • Export a QA report as CSV or PDF for tickets and audits PRIVACY AdSentry runs entirely in your browser. It collects nothing, sends nothing to any server, and never modifies the pages you visit. See the privacy policy for details. Built for news/media sites, ad-ops teams, WordPress publishers, and agencies managing publisher websites.
