Currently webs does not offer the Facebook pixel to your websites. Your competitors like wix do and that is a big advantage over webs as I have already made a new website at wix just for this perk. The facebook pixel is a html that you copy in your website, then facebook is able to tell all who has visited your website in which us as business owners can now pay to market to these website visitors on facebook and the millions of other websites that are are a part of facebooks ad campaigns.
This needs to be something that is available on webs if you all want to try and compete. Please add this to webs websites as I like your system better, but without the facebook pixel, I won't be able to stay with webs.
