Sites and migrations
Site limits and installation status
Understand plan allowances and the difference between detection and incoming data.
Starter currently includes one site; Growth increases the allowance. Near-limit warnings begin before the limit so you can upgrade or remove an unused site without interrupting setup.
Detected means PageDuel recently received the snippet heartbeat. Receiving pageviews confirms event data is arriving. A site can show detection but no data when the page is opened by a blocked/test browser, the selected domain is wrong, or event requests fail. Run Verify and inspect the deployed page when the states disagree.
