Adding a Twitter Pixel to Uscreen will allow you to track page views across your Uscreen storefront that came from Twitter referrals.
In your Twitter Ads account you'll find your tracking code under Tools > Conversion Tracking. Click on View code and installation instructions.
You'll see a line in the code with your website tag ID, copy that and head back to Uscreen.
Under Settings > Integrations select Twitter and on the next page paste in your Website Tag ID. Once connected your page views in your Uscreen storefront will start sending to Twitter so you can measure the effectiveness of your twitter ads.
