Best practices

To keep your Facebook account healthy and avoid spam flags, stagger identical posts across multiple Pages. Publishing many identical posts at the exact same time can be flagged as spam or bot-like behavior, which may fail posts and revoke your access token. In rare cases, Facebook may temporarily restrict the account. Example staggered schedule across five Pages:
  • Page 1: 09:30
  • Page 2: 09:34
  • Page 3: 09:39
  • Page 4: 09:42
  • Page 5: 09:47
