Some clients want to run ads on Instagram, must link with a page. Never link your Instagram with shared pages, as others using the same page can run ads on your Instagram.
Best to create a new page with your preferred name.
Then go to https://web.facebook.com/settings?tab=linked_instagram and start linking with Instagram.
Or, you can buy a private page from us, for your exclusive use.
If your Instagram account was linked to another page before, you’ll get a notification to confirm and re-login.
