Using Facebook Pixel Helper

30/11/2019

In this article, you'll learn what the Facebook Pixel Helper is and how to use it to make sure your pixel's set up correctly. If you're a developer, take a look at the Pixel Helper guide for developers.

Basics

The Facebook Pixel Helper is a troubleshooting tool that helps you find out if your pixel is working correctly. Once you install the Chrome plugin, you can see if there's a Facebook pixel installed on a website, check for errors and understand the data that's coming from a pixel.

Install the Pixel Helper

Before you start, you'll need to have the Chrome web browser. If you don't have it yet, install the Chrome browser then follow these steps:

  1. Go to the Chrome web store and search for the Facebook Pixel Helper.
  2. Click + Add to Chrome.
    3. "
  3. Click Add extension.

Once you have successfully installed the extension, you'll see a notification that the plugin has been added to Chrome and a small icon will show in your address bar.

Check that your pixel is working

  1. After you've installed the Pixel Helper, click the Pixel Helper icon in the address bar.
  2. Check the popup to see any pixels found on that page, and whether they've been set up successfully.

If the Pixel Helper finds a pixel on your site and there are no errors, then you're ready to start creating Facebook ads with your pixel.

If you see a notification that no pixels were found on your site or that there's an error, then have a look at the troubleshooting section below for more help.

Troubleshooting pixel errors

The Facebook Pixel Helper reports common errors that can happen when you install a pixel on your website. These errors mean that the person who manages your website will need to fix something for your pixel to start working correctly.

See how to fix some common pixel issues:

No pixel found
If you click the Pixel Helper icon in the address bar and see a message that no pixels were found on that page, it means that you will need to place the Facebook pixel code on your site. See how to set up your Facebook pixel.
Pixel did not load
This means that the Pixel Helper may have found Facebook pixel code on your site, but the pixel isn't passing back data from your site. There are two reasons this might be happening:
  1. If you've set up your pixel to fire on a dynamic event (like when someone clicks a button on your page). If that's the case, try clicking the button where you've attached your pixel code and clicking on the Pixel Helper again to see if this fixes the problem.
  2. There could be an error in your pixel base code. If this is the case, you can try deleting the Facebook pixel code you've placed on your site and adding the code again. Learn how to find your pixel base code in Facebook and put it on your site.
Not a standard event
This means that the Pixel Helper found event code on your site that doesn't match one of our nine standard events. This could be a typo, for example, if the event is named "Purchased" instead of "Purchase". Find Facebook's standard event names and the exact code you'll need to place on your site to make sure this matches with the event names in your website's code.
Pixel activated multiple times
This means that your pixel sent the same signal multiple times to Facebook (which would affect the accuracy of your site's reporting). To fix this, make sure that you've only included the Facebook pixel base code on your site once, and that if you have event code on your site you avoid placing the same event code multiple times on the same page.
Invalid pixel ID
This means that the pixel ID in your Facebook pixel base code isn't recognised by Facebook. To fix this, you'll need to replace the pixel ID in your pixel base code with the pixel ID assigned to an active ad account. Learn how to find your pixel ID.

Improve your pixel's performance

The Facebook Pixel Helper can offer suggestions on how to improve your pixel's performance, including:
  1. Track more actions on your site
    2. Place your Facebook pixel base code in the header of your website to help best track the actions you care about. If your pixel code is placed too far down on your page, then it's possible that some customer actions may not be tracked if they happen before your pixel fires.
  2. Opt in to tracking
    3. If you see the error below, then you've opted out of tracking from Facebook. This means that Facebook might not be able to detect if there's a problem with your pixel. To opt back in, you can go to your Facebook settings. You may also need to update your device's settings.

  3. Place one conversion event per page
    4. Facebook recommends placing no more than one conversion event per page, unless additional conversion events on the page only fire when a customer takes a certain action, like clicking on a button. This will help improve optimisation and tracking for your events.

Uninstall the Facebook Pixel Helper

If you'd like to uninstall the Facebook Pixel Helper, type "chrome://extensions" in the address bar of your Chrome web browser. Then click the bin icon next to the Facebook Pixel Helper extension.
