Hello jonaz,

Here's the short answer: dashes are best.

Next best might be underscores.

For the long answer, check this post out: http://www.seomoz.org/q/hyphens-v...

Hope this helps!

Hi jonaz, I think I was editing my post when you were replying. Dashes are best, yes. I'd say underscores would be second-best. If your developers can't work with dashes, then my suggestion would be to use underscores.

Using a plus sign (+) isn't bad. The plus sign represents a space character I believe.

Hey Jonaz, use the plus (+) sign. I think it's your best bet.
