See which pixels and tags run on any site, and which are missing.
The scan opens your site in a real browser and records what every tag sends, before and after the cookie banner, so you see which pixels work, which sit silent and what’s missing.
- Detects GTM, GA4, Google Ads, Meta, Microsoft Ads, LinkedIn, TikTok and 30+ more by the data they send
- Finds server-side tracking, first-party endpoints and server-set cookies
- Checks Consent Mode v2 and which tags fire before consent
- Add your thank-you page to see whether conversions fire
Your score, the full detection grid and a link to share the report are free. Add your email only if you want the step-by-step fixes.

The scan checks what Julio checks when he audits a client’s measurement.
Julio Lopez · Founder & Head of Growth, Lux Marketing (est. 2018)
This tool checks for the same things I look at when I audit a client’s measurement setup. As former Head of Growth at Glossi, I built server-side tracking infrastructure from zero, Jitsu CDP, BigQuery, identity stitching, and bot detection. At Lux I’ve delivered 40+ analytics implementations and 50+ pixel & API implementations, managing up to $75K/mo in ad spend for a single client, with a focus on server-side tracking and recovering the conversions most sites are quietly losing.
“Julio is a top notch Google partner for us. He is up to date on all the changes that Google constantly throws at you and is fast to respond to all our needs. Highly recommended.”

The gaps your scan finds can be fixed in a 30-day Measurement Sprint.
We set up tracking that ad blockers and browsers don’t break: server-side implementation, first-party data and attribution matched to your CRM or store, so fewer conversions go unattributed. Most clients start with the 30-Day Measurement Sprint ($1,250, one time).
Applying and the first call are free. The $1,250 is paid only if you decide to start.
