As you look to snip your URL's using a free service, there are several items to investgate.

First, do the links expire? If they expire, you may want to look to another service.

Second, is there a direct redirect? If, upon selecting the short Non Woven Mask URL, you are sent to a transition or intersitial page, this page may change in the future to display an advertisment of the free service. The preferable redirection is a direct link to your short URL.

Third, the service should check the URL and determine is is valid. Everyone makes typos, this simply check for valid URL format.

Fourth, how long has the service been in business? Longevity and reliability are crucial when you are snipping hundreds of affiliate links.

Fifth, is there any Terms of Service that you do not agree with? If there are, look for another service.

An alternative to the free services is your own snipping service, running from your server. This ensures your links are available until you decide to delete them.

Generally speaking, the short URL generators are php/MySQL driven scripts. You would need php installed on your server, your site administrator could tell you if it is. You would also need a MySQL database, again your site administrator could tell you if this is available to you.

Another item to check is the control panel page. It should be a php template that can be edited for color, position etc.

If you are using a shared hosting situation you may not be able to run a script that requires will not allow Mod Rewrites to be on, It should be a webmaster settable configuration.

What's the difference Mod Rewrites On/Off? As you compare the resulting snipped URL's, if has a ? in the URL; such as, http://snippedurl/?a then the script is set for Mon Rewrites off. This is probably not the preferable URL format. If there is no ? in the snipped URL then it may only be run with Mod Rewrites on.

As you look to snipping your URL's you may want to bring the service in-house to your server. This will give your site added stickyness as your customers, return time and time again to snip their URL's.
