dch.ie – you may have noticed a change in the web addresses used to share some content on Twitter. Beginning October 2012, the links are compressed into a custom short link dch.ie (DonegalCottageHolidays.com)
The customized short links are powered by Bit.ly, a service for trimming longer web addresses into bite-sized, easily shareable links.
It’s much easier to include the link in your facebook post or in an email or Twitter post without it breaking or taking up space.
How does bitly url shortening service work?
bitly works by issuing a “301 redirect”: a technique for making a webpage available under many URLs. When you shorten a link with bitly, you are redirecting a click from bitly to the destination URL. A 301 redirect is the most efficient and search engine-friendly method for webpage redirection, and is what bitly uses. Because bitly doesn’t re-use or modify links, we consider our redirects to be permanent.
