HOW DO I SET UP A BRANDED SHORT DOMAIN?
1) PURCHASE THE BRANDED SHORT DOMAIN YOU’D LIKE TO USE. This domain can only be used for your shortened URLs. Sites like Domai.nr, GoDaddy, and 101domain are great places to begin your search.
Note: Your Branded Short Domain name needs to be 15 characters or less, including the dot.
2) CREATE A DNS RECORD FOR YOUR BRANDED SHORT DOMAIN.
The Domain Name System (DNS) is what allows a web browser to translate a domain to a website. You will need to tell DNS that your custom domain now should point to Bitly.
The way you update DNS varies depending on your domain registrar. In general, the process goes something like this:
Log into your domain registrar’s website.
Select the Branded Short Domain you want to modify.
Find the section for managing DNS entries. The name of this section varies, but is usually something like ‘DNS Configuration, DNS Records, or Advanced DNS. Links to instructions for popular hosting providers can be found here.
For a domain:
Edit the existing A records for your site. If there is one or no existing A Record, add new ones. The A Record’s host name should be either the character ‘@’ or your base domain (both mean the same thing). If you have additional A Records pointing to other IP addresses, remove all others and leave only the ones pointing to Bitly’s IP addresses.
For a subdomain (such as on.wsj.com):
Set the CNAME Record for that subdomain to point to cname.bitly.com. When entering your subdomain, enter only the portion before the first dot. For example, with ‘on.wsj.com’ you would just type in ‘on’.
Note: In your DNS, you can also add a ‘www’ entry for your domain name, which you will point to ‘cname.bitly.com’. For example, if your Branded Short Domain was ‘fred.me’ you’d point your CNAME Record for ‘www.fred.me’ to ‘cname.bitly.com.’
