There are a few ways to measure traffic from your Facebook Page custom tabs:
- Use a Third-Party URL Analytics Tool – You can created bit.ly links for each URL in your custom tab. The downside with this is that you have to manage another service for this analytics.
- Create a Unique Web Page – You can also create a unique web page that only receives visitors from your Facebook Page custom tab. Although this is great from a messaging standpoint, it requires additional time and resources to build a new webpage on your site.
- Use UTM Tags – UTM tags allow you to amend an existing URL with information so you can measure traffic coming from a specific website or medium (like an email) where you’ve placed that URL.
