Pixel Auditor

Pixel Auditor is a real-time tracking pixel inspector for marketers, analysts, and developers. Open the side panel on any website and instantly see every tracking tag on the page, watch events fire live, and audit your implementation — no extensions, no browser DevTools, no technical setup required. ────────────────────────────────────── WHAT IT DETECTS ────────────────────────────────────── ✦ Google Tag Manager (GTM) ✦ Google Analytics 4 (GA4) ✦ Google Ads Conversion Tracking ✦ Google Merchant Center ✦ Universal Analytics (with retirement warning) ✦ Meta Pixel (Facebook Pixel) ✦ LinkedIn Insight Tag ✦ Microsoft Clarity ✦ Bing UET (Universal Event Tracking) ────────────────────────────────────── KEY FEATURES ────────────────────────────────────── ▸ Live Event Stream Watch pixel fires appear in real-time as you browse. See the event name, method (gtag, dataLayer, network), payload parameters, and exact timestamp for every fire. ▸ Health Assessment Automatically grades your tag implementation from A to F. Flags duplicate tags, retired pixels (Universal Analytics), missing consent signals, and other issues with plain-language explanations. ▸ Tag Forensics Goes beyond just "found it." Shows how each tag was installed — direct script, Google Tag Manager, CMS plugin — and surfaces duplicate init calls or misconfigurations. ▸ Consent Mode Timeline For sites using Google Consent Mode v2, displays the full consent signal history: default state on page load, and any updates when the user accepts or declines cookies. ▸ Tracking Cookies Lists all known tracking cookies set by detected platforms (_ga, _fbp, _gcl_au, _uetsid, _clck, and more) with the platform name, purpose, and value prefix. ▸ DataLayer Inspector Browse every dataLayer.push() call made on the page in chronological order. Perfect for auditing GTM container pushes and custom event payloads. ▸ Watch for Event Set a pixel + event name to watch for. Pixel Auditor sends a browser notification the moment it fires — useful when testing conversion tags or purchase events. ▸ Snapshot & Compare Take a snapshot of the current tag state, keep browsing, and instantly see a diff showing which tags were added or removed and how many events fired since the snapshot. ▸ Export HTML Report Generate a self-contained HTML audit report with a single click — tags detected, health score, event log, consent timeline, cookies, and server-side tracking signals. ▸ Server-Side Tracking Detection Identifies signals of server-side GTM (sGTM) setups, custom transport URLs, and Meta Conversions API usage. ────────────────────────────────────── WHO IT'S FOR ────────────────────────────────────── • Digital marketers verifying tag implementations • Analysts checking GA4 event data quality • Developers debugging tracking integrations • CRO and paid media teams auditing conversion pixels • Agencies auditing client websites before go-live ────────────────────────────────────── PRIVACY ────────────────────────────────────── Pixel Auditor collects zero data.
