There isn't any limit on the number of links you can include on your Link-in-bio page, but your account does have a monthly limit on the total number of links you can create in Bitly. This limit applies to (and includes) any links you create specifically for your Link-in-bio page.
For example, if you're on our Free plan with a limit of 50 links per month and you've already shortened 47 links this month, you can create three more before the end of the month—whether you're creating them for your Link-in-bio page, a QR Code, or a short link. Your monthly limits reset at the start of each month.
You can also use any of the links you've already shortened on your Link-in-bio page without any limitations.
