About Pixel Helper Guides

Pixel Helper Guides is run by the Pixel Helper team, the developers behind the Pixel Helper Chrome extensions. More than a thousand marketers, store owners and developers use our extensions to see which tracking pixels fire on a page — and the most common question we get afterwards is: "OK, it shows an error. Now how do I fix it?"

This site is our answer. Each guide takes one real pixel problem — a pixel that doesn't fire, an event that fires twice, a conversion that never shows up in the ads manager — and walks through the causes in the order you're most likely to hit them, with the exact steps to confirm the fix.

What we cover

• Meta Pixel and the Conversions API
• Google: GA4, Google Ads conversion tracking, Google Tag Manager and Consent Mode
• TikTok Pixel and Events API
• Reddit, Pinterest, Snapchat, LinkedIn and Microsoft Advertising tags
• Shopify tracking with app pixels, custom pixels and customer events
• Fundamentals that affect every platform: consent, ad blockers, browser privacy, single-page apps and Content Security Policy

How we write guides

• Facts about each platform are checked against the platform's own documentation, and we link to it so you can confirm.
• We don't publish invented statistics or made-up case studies.
• Ad platforms change their tools often. When a menu, parameter or policy changes, we update the guide and its "Updated" date.
• If something in a guide is wrong or out of date, please tell us. Corrections are the most useful email we get.

Independence
