Many of our customers choose to use an external service to help them dynamically place the pixel on their website. Google Tag Manager (GTM) is a popular choice.
Using a service to automate the pixel placing process can be helpful, especially when you have many pages on your website. If your product pages all have a common string in their URLs (which is not shared by other types of pages) then you may be able to automate the pixel placement. For example, you could set up a rule to implement the pixel on all pages which contain the URL string “/all-products/”
