We are an ecommerce site using Volusion. We are looking for someone to correctly install the Facebook Pixel. We have the Faebook pixel currently installed but it only works for PageView. We want the pixel to track add to cart, conversions, search, initiate checkout etc. Also, the pixel works on product detail pages but not on category pages (with more than 1 product on a page). We would like this fixed if possible. We use Google Tag Manager for the Facebook pixel. Experience with Facebook pixel and Google Tag Manager is required and with Volusion is preferred.
