Check if your pixel is working

Once you've clicked Save at the top of the tag page, you should check if your pixel is firing correctly. To check that your pixel is working properly:

1. Navigate to the web page that the pixel was placed on. If it's working, the pixel will send information back to Facebook and you'll be able to see activity on the Facebook pixel page in your Adverts Manager. Your pixel's status will also be set to Active. Bear in mind that the activity column reports all conversion events regardless of whether or not these events are associated with an advert.
2. If it didn't work (No activity yet, No recent activity), use the Facebook Pixel Helper to troubleshoot the problem. Bear in mind that you have to be using the Chrome browser for it to work. Once the Pixel Helper has been 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 which pixels were found on the page and whether they have loaded successfully. If not, it will give you tips on why it may have failed. Learn more.
