Best way to make my filenames Search Engine Friendly

[Web 3.0]

I am concerned about how to make my filenames as Search Engine Friendly as possible.

Let's say that I have a page about the Los Angeles olympics.

Does it make any difference if I use underscores to separate words in my page filenames

http://www.OlympicCentral.com/1984_los_angeles_olympics

or dashes

http://www.OlympicCentral.com/1984-los-angeles-olympics


I do know its generally a good idea to stay all lowercase with the file names.

But, Which is better with the Search Engines? Underscores or Dashes?

Or, Does it really matter?

Thanks! :)

Re: Best way to make my filenames Search Engine Friendly

Some se analysts will say one, some will say the other and some will say no difference. It seems at the moment they are leaning towards the dashes. Since I optimize my pages with the words correctly done, I do my names with no spaces. You'd be amazed how many people search that way and I then come up first :)

The page name is important, but only one of many things to use. So, use which one you prefer in this instance.
