I have added custom pixel codes to my website. As an example, a page has the following code: <script> fbq('track', 'try-heromask'); </script> I want to quantify how many people entered to that page by adding a column about that pixel in the PowerEditor. Is that possible? If not, what workaround do you use? Notice I have tried to add it as a column, but I don't see custom pixels, only default ones.
