title: What is the ideal length of an URL slug
body: <p>To make pretty URL's from article titles I am using a simple function. However lately I an concerned about the ideal length of these "slugs". It is said that too many dashes are bad.</p>
  
  <p>However some article titles can be long and a too long URL may not be liked by google. Of course that defeats th whole idea of having URL slugs.</p>
  
  <p>So does anyone have any idea how long a URL slug should be. Should there be a limit on the "dash" charecters used? </p>
