Find out your tracking is broken before your ad budget does.

PixelAlert is a Chrome extension that walks your Shopify store's purchase funnel and checks whether your Meta, GA4, TikTok and Google Ads tracking actually fires — and whether the data it sends is usable.

The problem it solves

Tracking breaks quietly. A theme update, a checkout change, a consent banner, an app you installed last month — any of them can stop a pixel from firing, or make it fire with the wrong data. Nothing errors. Your ad platforms keep showing numbers. They're just wrong, and they stay wrong until someone notices.

What you get

Free — the full diagnosis

Walk your own store with the extension on and get every finding we can see right now, in full detail: which events fired, which didn't, duplicate events, missing order values, broken currency codes, unhashed customer data, checkout events firing on the wrong page.

Pro — the time dimension

We check your store once a day from our servers and tell you when something that used to work stops working. Plus history, Shopify order matching, and multiple stores.

Pricing and the full feature list are on the pricing page.

What it checks

Whether each tracking vendor fires on each funnel step — home, product, cart, checkout
Whether the purchase event carries a usable value and a valid currency
Duplicate events, duplicate account IDs, and reused event IDs
Checkout events firing on the purchase-confirmation page (which inflates your funnel)
Customer email or phone sent without hashing
Meta server-side deduplication (Conversions API) consistency
Requests that failed to complete, and whether an ad blocker made the result unreliable

It reports, it doesn't repair. PixelAlert is a diagnostic tool. It tells you what is wrong and where to look; it does not change your theme, your pixels, or your store. And when it hasn't measured something, it says so rather than calling it clean — see how it works.

What it can and can't see

PixelAlert observes requests your browser makes to known tracking domains while you browse your own store. It does not read page content, form fields or customer data. Shopify's hosted checkout pages are outside what any browser extension can observe, and real customer purchases happen in your customers' browsers, not yours — so those are covered by the daily server-side check, not the extension.
