As answered by people managing CodePen and Tracking Auditor.
Tracking Auditor's answer:
It audits the whole tracking stack in one scored pass. Most tools check one layer: a tag scanner checks what fires, a consent tool checks the banner, GA4 add-ons check events. Tracking Auditor connects to GA4 and Google Tag Manager together, cross-references them against 30 days of real traffic data, and grades the setup A to F across five weighted dimensions: consent, GTM governance, GA4 event quality, cookies and conversion integrity. That cross-referencing catches the problems single-layer tools miss, like a key event with no working tag behind it, or a purchase event counted twice.
Tracking Auditor's answer:
The enterprise tools in this space (ObservePoint, TagInspector) start at hundreds to thousands per month and are built for compliance teams. Tracking Auditor produces a comparable audit in about two minutes for £120, or unlimited audits at £199 a month, and the output is built to be handed to a client: plain-English findings, a prioritised fix plan, and white-label Google Doc and Sheet exports. The first audit preview is free with no card, so you can see your grade before paying anything.
Tracking Auditor's answer:
Digital marketing agencies and consultants who audit client GA4 and GTM accounts, and in-house marketing or analytics teams who want an independent check on their own setup. Typical trigger moments: taking over a new client account, a site rebuild, a consent banner change, or numbers that stopped matching the order system.
Tracking Auditor's answer:
It came out of agency work. Auditing a client's GA4 and GTM setup by hand takes the better part of a day, the checklist lives in someone's head, and the same problems come up every time: tags firing before consent, duplicate tracking, conversions that quietly stopped recording. Tracking Auditor turns that manual process into a repeatable, scored audit so the finding-and-explaining part takes minutes and the time goes into fixing things instead.
Tracking Auditor's answer:
Next.js on Vercel, with the official Google Analytics and Tag Manager APIs for read-only data access, Anthropic's Claude for generating the written findings and fix plans, Postgres for audit history, and Stripe for billing.
