Analytics Tag Checker Tool Build

I built an analytics and lead tracking tag checker that detects common marketing tags and lead-capture signals on a page while making one caveat impossible to miss: tag presence does not prove conversion events are configured correctly.

A lot of marketing reporting problems start with a false assumption: the tag is on the site, so tracking must be working. In reality, a GA4 tag can load while zero useful conversion events are configured.

For service businesses, tracking and lead capture need to be reviewed together. A page with analytics but no phone link or form is measuring visits it cannot convert. A page with forms but no analytics cannot trace leads back to marketing channels.

The core product decision was honesty. The tool acts as a first-pass check before a deeper analytics audit. It can tell a user whether obvious signals are present, but account-level verification is still required to prove events, conversions, and GTM triggers are firing correctly.

This created a useful QA workflow for launch checks, audit intake, and conversations where a business owner says they have analytics but cannot tell which marketing is producing leads.
