iZap is a free service that shortens links. This is useful in Twitter & in websites that break long links.
iZap works by issuing a 301 redirect : a technique for making a webpage available under many URLs.
When you shorten a link with iZap, you are redirecting a click from iZap to the destination URL.
A 301 redirect is the most efficient and search engine-friendly method for webpage redirection, and is what iZap uses.
Because we does not re-use or modify links, we consider our redirects to be permanent.
Certain uses of iZap are forbidden, for example use in unsolicited commercial email (SPAM).
