A change to the Facebook pixel will now pass a page’s click data and metadata back to Facebook.
Facebook is alerting advertisers about changes that are coming to its Facebook pixel May 20. The Facebook pixel helps track conversions, optimize ad spends and retarget users. An upgrade to the pixel was just rolled out that will now capture more information, including actions and page structure and data.
According to the Facebook for Developers page, you can also turn off this new upgrade by implementing the following instructions:
If you’d like to configure the Facebook Pixel to not send this additional information, you can add the line fbq(‘set’, ‘autoConfig’, ‘false’, ‘FB_PIXEL_ID’) above the init call in the Facebook Pixel Base code and the Facebook Pixel will no longer send this additional information.
If your pixel was created before April 20, the new functionality will be go into effect on May 20. If the pixel was created after April 20, the functionality will be active now.
