What’s the Best URL Shortener out There?
The guys over at WatchMouse did a really interesting comparison: The set a bunch of URL shorteners against each other to see how good they really are. WatchMouse monitored 14 popular URL shorteners for a month and took a long, hard look at availability and speed. Interestingly enough, only goo.gl and twt.tl were always available during the testing period. In terms of speed, Facebook’s fb.me ist by far the slowest of them all and goo.gl reigns supreme.
Also, it seems that only a few of the shortening services optimized their DNS servers for international use. If you’re in the same country as some of the services have their servers stashed, you can look up the IP address half a second faster than an international visitor. In addition to these findings, WatchMouse figured out that bit.ly’s pro service – a paid version offering more options – is slower on average than the free counterpart.
Personally, I don’t use URL shorteners because I like to see where a link gets me. There are a few add-ons and/or userscripts for Firefox to keep you on the safe side though, by expanding shortened URLs. Anyway, if you can’t avoid the use of such a service check out the new website the guys from WatchMouse have set up: the site provides real-time status reports for URL shorteners.
