Tracking Health Check: GA4, Tag Manager and Pixel Checker

Tracking check for GA4, Tag Manager, Meta pixel and Google Ads tags on any public page. A Google tag checker with fixes. 2 credits per run.

Most marketing teams make budget decisions from numbers they've never verified. GA4 shows one conversion count, Google Ads shows another, Meta shows a third, and nobody can say which is right. A tracking health check looks at what is actually installed and firing on your site, so you know what is missing or doubled before you move more budget on bad data.

The Tracking Health Check from Dynamic Growth is fully automated software. You enter your website URL and our system scans your public pages. It detects GA4, Google Tag Manager and ad pixels, looks for key conversion events firing on your pages, and returns an issues list with a severity on each item. We never connect to or log in to your Google, GA4 or Meta accounts.

The check costs 2 credits, and you download the report from your dashboard. Because the scan only sees your public website, it can't read your account settings or your backend numbers, so read the report with that in mind. Ad spend is always paid separately to the platforms and never comes out of your credit balance.

What you get

Report on detected tags, missing events and tracking issues.

GA4 and Tag Manager detection

The scan looks for GA4 measurement tags and Google Tag Manager containers on your pages. It reports what it found and where, and flags pages where a tag you'd expect is absent or appears more than once.

Ad pixel detection

The scan checks for ad platform pixels such as the Meta Pixel and Google Ads tags. It notes which pages load them and whether the same pixel shows up twice, which is a common cause of inflated counts.

Key conversion event check

The report lists the conversion-style events it saw firing on your pages, such as page views, form submissions or purchases, and points out important events that never appeared. Events behind a login or a payment step may be out of reach of a public scan.

Duplicate and broken tag warnings

Tags loaded twice, tags that fail to load and tags that look misconfigured are listed with the page where each one turned up. These are the usual reasons for double counting or missing data.

UTM and consent banner notes

The report adds notes on UTM handling and on whether your consent banner seems to affect how tags load. These are observations from the public site, so treat them as prompts to check your own setup.

Issues list with severity

Findings arrive as one list, each with a severity rating, so you can see what distorts spend decisions today and what is housekeeping.

Why a tracking health check matters

Every optimization decision rests on conversion data. Smart bidding in Google Ads learns from the conversions you send it, and Meta's delivery system does the same. If those signals are duplicated, delayed, missing or attached to the wrong action, the algorithms optimize toward the wrong outcome and you pay for it in higher acquisition costs.

Tracking also decays without anyone noticing. A site redesign changes a button class and a click trigger stops firing. A developer removes a data layer push. A consent banner update blocks tags on some pages. None of it throws an error, so reports keep arriving and look plausible while the underlying data drifts away from reality.

A scan of your live site gives you a baseline to work from. It helps separate real performance problems from measurement problems, which matters when a campaign looks like it's failing. Sometimes the campaign is fine and the tracking is broken, and sometimes it is the other way round. Checking what the site actually does is the first step to telling them apart.

How it works

1. Enter your website URL

   Type the address of the site you want checked and confirm the credits. There's nothing to connect or install, and no one needs access to GA4, Tag Manager or your ad accounts.

2. The system scans your site

   Our software loads your public pages, records which analytics tags and ad pixels are present and which events fire, and compares that against common tracking problems. No person is involved at any stage.

3. The issues list is generated

   The system turns what it found into a list ranked by severity, with each issue written in plain language so a marketer and a developer can both read it.

4. Download your report

   The report appears in your dashboard. Read it before acting on it, since it is generated automatically from a scan of the public site and a developer should confirm anything that depends on your accounts.

5. Apply the fixes yourself

   Make the changes in your own site, Tag Manager or ad accounts, or pass the list to your developer. Nothing in your accounts changes unless you change it. Run the check again afterward to see what's resolved.

Common problems the scan looks for

Duplicate conversion counting

A purchase fires once from a hardcoded tag and again from GTM, so revenue appears doubled. You see inflated ROAS and conversion counts that exceed actual orders, and budget ends up misallocated. Keep one source per event and verify the count against your backend.

Key events that never fire

A form submission or call click was configured once, then a site change broke the trigger. Reports show zero or very low volume and the campaign gets blamed. Repair the trigger, then test in GTM preview and GA4 DebugView.

Pixels loaded twice or on the wrong pages

The same pixel sits in the page code and in Tag Manager, or fires on pages where it has no business. Counts inflate and audiences fill with the wrong people. Choose one route for each pixel and remove the other.

Inconsistent UTM tagging

Links use utm_source=Facebook in one place and facebook in another, or leave email links untagged. Traffic splits across multiple rows or lands in Direct. Agree one naming convention and give everyone a short link builder.

Missing tags on some pages

A template change drops the tracking snippet from checkout, a landing page or a blog section. Visits and conversions there never get recorded. Compare page types and restore the tag wherever it's missing.

Consent settings blocking tags

A cookie banner may block tags more broadly than intended, or Consent Mode may be only partly implemented, and less data comes in than you expect. Align consent signals with tag behavior and confirm what loads before and after consent.

What the report looks at

• Event firing. Whether each tracked event appears when the matching action happens on the page. A key event that fires inconsistently often points to a trigger or page-load timing problem.
• Tag presence by page. Which pages carry GA4, Tag Manager and ad pixels, and which don't. Gaps usually trace back to a template or a plugin.
• Duplicate tags. How often the same tag or event shows up more than once, whether from double installs or from a hardcoded tag next to a Tag Manager one.
• Broken or failing tags. Tags that fail to load or return errors. A tag that silently fails is the same as no tag at all.
• Campaign link tagging. What the scan can see about UTM handling on your public pages. A large Direct or Unassigned share in your analytics often has this cause, but the scan can't see your analytics, so confirm it there.
• Consent behavior. Whether your consent banner appears to delay or block tags. Check the details in your own consent tool.

Do it yourself or run the automated check?

A manual check is reasonable if you have one site and time to work through GTM preview mode, GA4 DebugView and Meta's Test Events tool. Free tools such as Tag Assistant and the Meta Pixel Helper show what fires on a page. You also get to see inside your accounts, which a public scan can't do. For a simple lead form site, a careful afternoon may be enough.

The automated check suits you when you have many pages to cover, when you inherited a site nobody documented, or when you want a quick second opinion before a decision. It costs 2 credits and covers the common failure points on every page it scans. It won't see account-level settings or your backend numbers, so a manual look is still the way to confirm anything that depends on those.

Who it's for

A Google tag checker for GA4, Meta pixel and conversion tracking

The Tracking Health Check is a Google tag checker and a quick GA4 audit for what is visible on the public page. It detects GA4, Google Tag Manager, the Meta pixel, Google Ads, TikTok and other tags, flags tags that appear twice or not at all and notes whether a cookie consent signal is present. People who search for a Meta Pixel Helper or a Google Analytics checker are asking for the same first look.

It cannot see inside your analytics or ad accounts, so it cannot confirm that conversion tracking records every event. Treat it as the first check before you test conversions with your own tools. The consent notes matter most for sites that serve visitors in the UK and Europe, and the tag checks apply to advertisers in the USA, the Middle East and Latin America as well.
