If you're switching your link management provider from another service to Bitly and you want your previously made custom links to continue to work you'll need to reshorten them in the Bitly platform.
First you'll want to make sure you add your custom domain to your account. Make sure you configure your DNS settings to point at Bitly and have the domain added and verified in your account.
Once your domain is verified create new links in your account by pasting the same long URLs from your previous links and customizing their backhalves to the same keywords from your old link. (Please keep in mind all links are case sensitive.)
Once you generate the links they will resume working wherever posted and will direct to your desired location while tracking your clicks.
