What makes a “friendly URL”?

Question

I\'ve read a great deal of discussion recently (both on this site and elsewhere) about \"friendly URLs\" but I\'m not sure what exactly makes a URL \"friendly\" and why we r

Answer 1

To me, friendly URL means there's been some attempt to include semantic information in the URL to make it more fit for human consumption. It's an interesting example of a computer-computer interface being augmented and built upon to make a better human-computer interface.

So, in your two examples:

• www.myblog.com/posts/123/this-is-the-name-of-my-blog-post is friendly, because you've included the title in the URL - it tells you something about the page.
• www.myblog.com/posts.aspx?id=123 is unfriendly because it's cryptic and obscure: it makes perfect sense to a database, but none to you or me.

Friendly URLs are fantastic in some situations and useless in others. Basically, if a user is ever going to be exposed to it, I'd make friendly URL creation a priority, and it's not just a matter of aesthetics. It makes it much easier to get back to URLs from the address bar if you can quickly see and understand what the various options are, plus it makes it more obvious where you're about to go if you're following a link from a web page.

Combine all that with the awesome bar in Firefox 3+ (surely coming in other browsers too), and auto-complete in the address bar becomes incredibly powerful when you're dealing with friendly URLs.
