Your Shopify Pixels, Tags & TrackingAre Probably Broken
Duplicate pixels, missing funnel events, Shopify Customer Events that never reach GA4 — most stores are flying blind without knowing it. Run a free audit and see exactly what's wrong in under 60 seconds.
Detects gaps across GTM, GA4, Shopify trekkie, Web Pixels, and Customer Events — including the most-missed event on Shopify stores: checkout_shipping_info_submitted.
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.
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.
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.
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.
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.
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.
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.
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.
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.

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.
Shopify Customer Events → GA4 mapping
Detects every major pixel and tag
The audit scans for hardcoded scripts, GTM container tags, Shopify Customer Events integrations, and live network hits from every platform your marketing team actually uses.
