How do page views work across sub accounts?

Do page across sub accounts add up to total views?

Yes, all views on sub accounts will be added to the total views on the master account.

You can see the total amount of views when signed into the master account by going to the billing section in your settings.

When the master account has a custom or unlimited pageview allowance, each sub-account will have the expected number of pageviews for the plan type:

Starter - 5k pageviews per month
Essentials - 10k pageviews per month
Business - 50k pageviews per month
Professional - 20k pageviews per month
Enterprise - 40k pageviews per month

Can you see page view per sub account?

You can only see page views as a total number
