Domain verification is easy to overlook because an unverified domain may appear to work normally at first. The problems often become visible later, when several people or ad accounts are using the same website. Verifying a domain confirms which Business Manager has authority over the links, editing permissions, and conversion settings associated with that website. Meta's own domain verification documentation explains the available verification methods and the control they provide. Without verification, people who have access to a Page may be able to change link previews or destinations connected to the domain. Verification also affects conversion event management. When several teams or ad accounts share one domain, the correct Business Manager needs control of the event configuration. Otherwise, one team's changes may interfere with another team's reporting. Marketing 360 walks through in detail how verification connects the domain with its conversion events. Content teams can run into problems as well. Meta may limit editing for links used in organic or unpublished Page posts when the domain has not been verified. Complete domain verification before installing the pixel and launching campaigns. The process usually involves adding a DNS record or uploading a verification file to the website. Doing this early can prevent hours of investigation when permissions or conversion reports do not behave as expected. bm2500 provides instructions for both methods if direct DNS access is unavailable.
