The script offers 5 types of the redirection that you can use. Each of them are explained below.
A direct redirection method redirects the user without any intermediate page. This is done via the server redirect. When sharing the link having a direct method, crawlers will fetch directly the target page. When using a pixel with direct method, a page is shown briefly before redirection and it is required for the pixel to work.
The frame redirection method is useful when you want to cloak a website like an affiliate page. It will show bar at the top with the site information, an ad slot and some buttons to share or close the frame.
Note that some websites do not work with this method because of a security rule that forces browsers to hinder iframes.
The splash page is an intermediate page very useful to give the user a preview of the page they are about to be redirected. It serves as a measure of protection and gives the user some time to react and decide whether they want to continue or not.
Custom Splash Redirection
The custom splash redirect is a premium feature that allows customers to create their own promotional page and associate it to a short link. A user going through the custom splash page will see a promotional page briefly before being redirected.
The overlay feature is a cool feature that allows you to use dynamic lead widgets. It uses the same principal as the frame method but without the top bar. Instead it injects some cool widgets like a popup message, contact form and a poll.
