Bad tracking costs real money

Broken conversion events don't just give you bad data — they actively make your ad campaigns worse by feeding wrong signals to Google and Meta's bidding algorithms.

Your ROAS is a lie

Duplicate pixels and double-fired events inflate conversion counts. Google Ads thinks it's getting credit for sales that never happened — and your smart bidding is optimizing toward phantom revenue.

Checkout abandonment data you can't trust

If begin_checkout or add_payment_info aren't firing, your funnel reports are incomplete. You're making budget decisions with a map that's missing half the road.

Broken tracking = broken attribution

A purchase event that fires twice, or not at all, corrupts every attribution model downstream — Google, Meta, TikTok, and your own reporting all see a different story.

For Agencies

Stop inheriting tracking chaos

New client onboarding shouldn't start with days of manual tag archaeology. Run an audit in 60 seconds and walk into the discovery call already knowing what's broken.

Every new client is a different mess

Hardcoded Meta Pixel fighting the GTM version. GA4 firing twice. An old UA tag nobody turned off. You inherit chaos and you're expected to fix it before the first reporting cycle.

Hours wasted on manual tag hunting

Checking the source, opening GTM, firing test events, comparing network requests — multiply that across 10 clients and you've lost a full week before you've done any real work.

Hard to show clients why their data is wrong

Clients don't understand tag conflicts. An instant audit report with clear pass/fail results is how you prove the problem exists and justify the fix — before you've written a single line of code.

What the audit checks

Not a simple tag presence check. A real headless browser runs your page, fires network beacons, and inspects the live dataLayer — then cross-references GA4 event names against Shopify's native Customer Events naming to catch gaps that standard audits miss.

GTM container detection

Confirms GTM is installed, placed in the <head>, has a noscript fallback, and the dataLayer initialises before the container fires.

Full ecommerce funnel mapping

Checks all 11 checkout stages — from view_item_list through add_to_cart, begin_checkout, add_shipping_info, add_payment_info, and purchase — against your live dataLayer and GA4 network hits.

Shopify Customer Events & Web Pixels

Detects Shopify's trekkie library and Web Pixels API, scans loaded JavaScript for Shopify native event names (checkout_shipping_info_submitted, checkout_started, product_viewed, etc.), and flags gaps between Shopify events and GA4 mapping.

Hardcoded script detection

Scans page HTML for 14 vendors loaded outside GTM — Meta, GA4, TikTok, LinkedIn, Clarity, Hotjar, Pinterest, Reddit, X Pixel, Klaviyo, HubSpot, and more.

Real-time network verification

Runs a headless browser audit that actually fires each page and captures network beacons — so you see what Google, Meta, and TikTok actually receive, not just what the code claims to send.

Duplicate tag detection

Identifies cases where the same vendor is loaded both hardcoded in HTML and via GTM — the most common cause of inflated conversion counts and double-counted revenue.

AI-powered recommendations

Every issue comes with a plain-English explanation of the impact and a specific fix — not just a red circle next to a tag name.

Ecommerce Funnel

Every stage from browse to purchase

Most audits only check if your purchase tag fires. That's one of eleven stages where data can go missing. PayHelm maps your entire checkout funnel and tells you exactly which events are firing, which are absent, and what each gap means for your reporting.

For Shopify stores, the audit shows both the GA4 event name and the corresponding Shopify Customer Events name side by side — so you can see exactly where the mapping breaks down.

Critical events like view_item (product_viewed), add_to_cart (product_added_to_cart), and purchase (checkout_completed) feed Google Ads smart bidding, Meta's purchase optimization, and your abandoned cart sequences. If they're silent, your campaigns are guessing.

Shopify-Specific

Why Shopify tracking breaks differently

Shopify's tracking architecture — trekkie, Customer Events, Web Pixels, and the isolated checkout domain — creates failure modes that don't exist on other platforms. The audit knows the difference.

Trekkie vs. Customer Events

Shopify's legacy trekkie library and the newer Customer Events / Web Pixels API use completely different event naming conventions. The audit detects both and flags when only one side is present — so you know whether GA4 is actually receiving the data.

Checkout runs on a separate domain

Shopify checkout lives on checkout.shopify.com, not your storefront. Scripts that fire on your homepage don't automatically fire in checkout. The audit inspects JavaScript across multiple page types to catch events that are configured on the storefront but missing from checkout.

Web Pixels run in a sandboxed iframe

Shopify Web Pixels execute inside a sandboxed iframe with no direct DOM access. Events like checkout_shipping_info_submitted may appear in your Customer Events settings but never reach GA4 if the outbound mapping isn't configured. The audit surfaces this gap explicitly.

add_shipping_info is the most-missed event

Most Shopify stores configure GA4 tags for add_to_cart, begin_checkout, and purchase — but skip the shipping step entirely. This leaves a blind spot in your checkout funnel analysis and makes it impossible to measure drop-off between checkout entry and payment.
