Hi depaw,
If you are referring to Moz Pro, you need to connect the Google Analytics account and confirm that it is active and properly set up. If you're still not seeing traffic data in Moz Pro, it might be worth reaching out to Moz support for further assistance.
With Google Analytics connected to Moz Pro, your Campaign will gather even more insights for your site within the Site Traffic and Landing Pages sections of your Campaign.
Remember, the traffic data in Moz Pro is a reflection of what's in Google Analytics, so ensuring that data is being accurately collected there is key.
Hope that helps
