Check what's really tracking on your website.

A website tracking checker scans a site from the outside and reports what analytics and marketing tags are actually running. Sonar checks GA4, Google Tag Manager, ad platform pixels, dataLayer events and consent setup, then scores your tracking health and only reports problems it can prove from the crawl.

Paste your URL into the scan above. Sonar crawls your site the way a visitor's browser sees it and reports whether GA4 is present and firing, with the evidence attached. Nothing to install, no access to grant.

Every tag and pixel it finds live on your site: GA4, Google Tag Manager containers, Meta and other ad platform pixels, dataLayer events, and how your consent setup interacts with them. It tells you what's firing, what's broken and what's missing.

Yes. The scan is free and needs no account. An email address only unlocks the full report.

Yes. Sonar works from the outside, exactly the way a visitor's browser sees your site, so there is nothing to install and no account access to grant. Form inputs are never recorded.

Tag Assistant inspects Google tags in your own browser, on the pages you visit, while you watch. Sonar scans the whole site from the outside, covers non-Google pixels too, and turns the findings into a scored report you can act on or hand to whoever looks after your tracking.

Yes, as the automated first pass of one. Sonar covers the ground a manual tracking audit starts with: what's installed, what's firing, what's broken and what's missing, with evidence for every finding. If the report surfaces problems worth a deeper look, the free audit is the natural next step.

You get the findings, and what you do next is up to you. If the report surfaces problems you want fixed, the free audit is how a Dolphin Analytics engagement starts, and Sonar's findings give that conversation a running start.
