<\/span><\/h3>\nYou won\u2019t be able to check this for every kind of Facebook Pixel Events, but the Facebook Pixel PageView can be definitely checked against Google Analytics PageViews metric.<\/span><\/p>\nTo see the number of Pixel PageView events, you can check that by going to the Overview tab of the specific Facebook Pixel and under the Events section, check the PageView Event row. Here the number you will see as \u2018Total Events Received\u2019 will tell you how many PageView events this FB Pixel recorded.<\/span><\/p>\nIn Google Analytics you can check the same metric by going to Behavior\u2192 Overview page and look for the Pageviews metric.<\/span><\/p>\nThe two numbers don’t have to be exactly the same, but if there is a big difference between the two, it shows that there is an issue with either your Facebook Pixel or your Google Analytics tracking.<\/span><\/p>\nUpdate: with the iOS14 update unfortunately this is only worth checking for Android devices.<\/p>\n
<\/span>6. Which websites are sending data to Facebook via the Facebook Pixel?<\/b><\/span><\/h3>\nAnother thing that is worth checking before starting to audit the specific Standard and Custom Events is which domains send Pixel data to Facebook from this particular FB Pixel.<\/span><\/p>\nIf you find that other websites that are not related to your site are sending data to Facebook via this Pixel, then you should remove or block the Pixel from those websites as it will lead to inaccurate tracking.<\/span><\/p>\nTo find out which websites send data to your website, you should click on this link: https:\/\/business.facebook.com\/events_manager2\/list\/pixel\/, choose the FB Pixel you are currently auditing and click on the \u2018number+ more\u2019 link on the right side of the screen.<\/span><\/p>\n<\/span>Standard Pixel Events Audit<\/b><\/span><\/h2>\nThe second part of this Advanced Facebook audit, is the Standard Pixel Events Audit that is is the most important part of this audit. <\/span><\/p>\nEvery website will have at least the PageView event set up if they install the Facebook Pixel on their website. For an ideal FB Pixel Setup, almost every site should have at least a couple of Standard Events active on their website so they can also run FB ads campaigns with a conversion objective.<\/span><\/p>\nWe have a 4-point checklist that will help you to evaluate each of these Standard Events that are currently set up for your website and see if there are Standard Events that are missing from your current implementation. <\/span><\/p>\nKeep in mind that one of the Facebook audit checkpoints is related to the Object Properties of the Standard Events but not all the 17 Standard Events have required Object Properties.<\/span><\/p>\n<\/span>7. What Standard Events are set up right now?<\/b><\/span><\/h3>\nAs we mentioned, there are 17 Standard Events predefined by Facebook at the time of writing this article. In most cases, you will have less than 10 Standard Events set up for your website which is totally okay as it is very rare that it makes sense to set up more than 10 Standard Events. With the iOS 14 update Facebook will only allow 8 Events anyway.<\/span><\/p>\nYou can check all of your Facebook Pixel Events that are receiving activity on the Overview tab of your Facebook Pixel<\/span><\/p>\n<\/p>\n
<\/span>8. Are there important Standard Events missing from your implementation?<\/b><\/span><\/h3>\nBefore you would audit the Pixel Events that have been set up an important question to ask if there are any Facebook Pixel events currently missing from the website. <\/span><\/p>\nIf there is an important user action that is currently not tracked by the Facebook Pixel, then you should definitely set that up.<\/span><\/p>\n<\/span>9. Are the Standard Events having any implementation issues?<\/b><\/span><\/h3>\nFrom this point, you should go over each Pixel Events and analyze checkpoints 9 and 10 for each of them.<\/span><\/p>\nFirst, we want to check if the specific Pixel Event is recording data when it should be recording data and if the number of Pixel fires is accurate. You can check this in multiple ways as well, we will share two methods for it.<\/span><\/p>\nThe first method is the one we have already mentioned. Let\u2019s say you want to check a Purchase Standard event. In this case, you can compare the number of Purchases recorded in Google Analytics with the number of Purchase Events firing in Facebook Events Manager. If the two numbers are close to each other, we can assume that the general setup of the Purchase event is correct.<\/span><\/p>\nA second way is to check on which pages the Pixel Event has activated on your website. You can do this by going to the Overview tab of your Facebook Pixel, then click on the Pixel Event you are analyzing and then click \u2018View Details\u2019.<\/span><\/p>\n<\/p>\n
Here you will be able to see on which URLs the Pixel Event activated and how many event parameters were sent in to Facebook:<\/span><\/p>\nTo continue with the previous example, if you see that the Purchase event is not only firing on a \u2018thank-you\u2019 page, that might indicate that the setup is incorrect.<\/span><\/p>\n<\/span>10. Are the necessary Object Properties\/parameters sent in with the Standard Event in the right format?<\/b><\/span><\/h3>\nIf you are sending in the Pixel Event at the right user interaction, the next things you should check are Object Properties or as also called Event Parameters. With the right event parameters and values, you will be able provide additional information to Standard Events that both you as the advertiser and the Facebook algorithm can take advantage of.<\/span><\/p>\nThere are Standard Event parameters that are required for certain Standard Events, there are certain Standard Events where there are no predefined event parameters so we cannot provide you.<\/span><\/p>\nAs a best practice, it is recommended to send in all the predefined event parameters as then Facebook can also use them. You can also use the event parameters and values to set up more segmented Custom Audience which will translate into better targeted retargeting and lookalike audiences.<\/span><\/p>\nTo see the full list of predefined Object Properties of FB Standard Events, check out our article on the 17 Facebook Standard Events.<\/span><\/p>\nWhen you are auditing the Standard Events, you should not only check if the event parameters are set up, but also see if the event values are sent in the right format. We have written extensively about how you can check id the Standard Events are having issues in our Standard Events guide.<\/span><\/p>\n<\/span>Facebook Pixel Custom Events Audit<\/b><\/span><\/h2>\nUnlike Facebook Standard Events, as the name implies, Custom Events are not predefined by Facebook, so it is more difficult to give you a standardized template that you can use to audit the Facebook Custom Events implemented for your Facebook Pixel.<\/span><\/p>\n
