Troubleshooting errors that happen while working with Facebook Pixel and Facebook Pixel Helper

We recommend downloading the Facebook Pixel Helper to troubleshoot implementation problems.

• Keep in mind you have to be using the Google Chrome browser for it to work. Once the Pixel Helper is installed, a small icon  will appear next to your address bar. Navigate to your website in your Chrome browser and click the Pixel Helper icon.
• The pop-up will tell you what pixels/events were found on the page, and whether they have loaded successfully.
• If you added standard events to your pixel code on certain pages, you'll need to complete a test conversion for each (example: add an item to your cart to test an “AddToCart” event) in order to confirm that each event loads on the desired page or action.

It works!

If your pixel's PageView event loads on every web page, and each of your standard events load successfully (on the desired pages only), you're ready to attach the Facebook pixel to your ads.

There are errors...

In order to resolve most Pixel Helper errors you'll need to check the HTML code on the web page where you received the error.

To check the HTML code:

• go to the desired web page;
• right-click on the screen;
• select “Inspect”; then
• search for your pixel ID (you can usually use “Control + F” or “Command + F” to bring up your browser's search bar).

I don't have the pixel ID in the code...

• If you don't find the pixel ID anywhere in the code, it may have not been placed on that page.
• If you installed the pixel using a tag manager then you won't see the code on the actual web page, so you'll have to troubleshoot within your tag manager.

I see the pixel ID!

• If you do find the pixel ID, check the code carefully against your code in your pixel dashboard (under Actions > View Pixel Code) to make sure everything between the <script> and </script> tags is exactly the same and that the pixel wasn't placed in the middle of another code block on your web page.
• You should find two instances of your pixel ID on each page where you placed the pixel (one in the <script> portion of the code and one in the <no script> portion. If you find more than two, it's likely that the code has been placed multiple times, so you can delete any additional instances.
• When troubleshooting standard event implementation, make sure the the event code (ex. fbq('track', 'Purchase', {value: '0.00', currency:'USD'}); for a Purchase event) is placed either:

  1. Directly between the “;” after the PageView event and the </script> tag, or;
  2. Directly below the entire base code (in which case you'll need to add <script> directly before the event code and </script> directly after the event code).
