Pixel & Tag Checker: GA4, GTM, Meta Audit – The Growth Folks®

Check GA4, GTM, Meta, TikTok and ChatGPT Ads pixels, see what fires before consent, and send clients a polished audit report.

Is your Meta pixel firing? Is GA4 tracking purchases? Do your tags fire before visitors accept cookies? Pixel & Tag Checker answers all three in one click, then turns the result into a report you can send to a client. Instead of installing a separate helper for each ad platform, check every tag on the page at once, including tags deployed through a tag manager, server-side tagging and e-commerce custom pixels. WHAT IT CHECKS • Tags found on this page: Google Analytics 4, Google Tag Manager, Meta, TikTok, ChatGPT Ads and 11 more ad and analytics platforms (full list on our website). Firing, not firing, firing twice, or blocked by an ad blocker, with the HTTP status of every request. • Consent timeline: what each vendor sent before the cookie banner choice and after "Accept all" or "Reject all", with a pass or fail per vendor. Reads Google Consent Mode v2 and Microsoft Ads consent signals; flags tags that fire before consent or after reject. • Cookie banner test: clicks "Accept all" or "Reject all" on major consent platforms for you and compares before and after. • Global Privacy Control (GPC) test for US privacy laws. • ChatGPT Ads pixel: decodes events, amounts and the oppref click ID, checks the click ID is captured, and warns if a Conversions API key is exposed in page code. • Meta data restrictions pre-check: health and other sensitive words in URLs, UTMs, custom events and custom data that may get your events restricted, with the fix. • Purchase events: value, currency, order ID and items; duplicate purchases; values that differ between platforms; event IDs for server-side deduplication. • Personal data (email, phone) sent to ad platforms, and unhashed user data. • Cookies set on the page, by vendor and purpose (names only, never values). TOOLS FOR THE JOB • Request inspector with readable parameter names, filters, search and CSV, JSON or HAR export. • dataLayer timeline from the first line of the page. • Funnel mode across pages (product → cart → checkout → thank-you). • Multi-page scan with a coverage check for templates missing tags.
