Quis breviaret ipsos breviares – who shortens the URL shorteners?

March 27, 2009 One Comment

Inspired by a comment from Christian Schenk (@christianschenk), I've tested which URL shorteners make themselves longer when self-applied (if they're in my URL shorteners review but not listed here, then they won't generate a URL for themselves). Just for something to do.

URL
Shortener
URL length 'Short' URL length Increase % increase
Ow.ly 12 17 5 41.7
Bit.ly 13 18 5 38.5
Short.to 15 20 5 33.3
Snurl.com 16 22 6 37.5
Twurl.nl 15 22 7 46.7
Tinyurl.com 18 25 7 55.6

Headings explained

  • URL length Length of original URL (including http://)
  • Short URL Length of the shortened URL each service generates for itself
  • Increase How many characters bigger this is
  • % increase What the % increase is

  • It's amazing that some services haven't got more sophistication here. You could expand the table above with a column for "accepts invalid URL" - and you could write a "yes" in all six rows! Try shortening "foobar" and it'll work; IMO this should throw an error.

    Anyway, as always nice research and a good read.
