You can track 5 sources on the Small plan, 40 on the Medium plan and 100 on the Large plan. On the Large and Premium plans you can purchase additional sources if you wish. Please note we cannot add extra sources to Small and Medium plans.
Sources are counted across your team. This means, for eg., that teams on a Large plan can track 100 unique sources in total.
To see how many sources you and your team are following check out the Manage Sources page.
