Creating an adult short link with ShrtFly is very easy:
Log in to your shrtfly.com account.
Click on the 'Create Link' button.
Click on the 'Advanced Settings' option to extend the menu with additional options.
Choose your desired short link domain from the drop-down list.
In the next drop-down menu, 'Mainstream' is the default link type.
Click on 'Mainstream' and then select 'Adult' from the options.
Now paste your long link and click the 'Shorten' button.
Congratulations! You have successfully created an adult-shortened link.
You can create mainstream links using the same method—simply select the "mainstream" link type.
If you are using the developer API or full-page script, you need to adjust your account's "Ad preferences" in the settings.
By configuring this setting, all your links will be shortened using the selected link type by default.
If you have multiple types of traffic, such as mainstream and adult, you will need to create the links manually in those cases; there is no other automatic way.
