Can I use underscore in url instead of hyphen?

I would like to use underscore in my url instead of hyphen. I mean like this wikipedia link

My Current url:

www.example.com/2013/01/hello-this-is-a-test-post/

Desired url

www.example.com/2013/01/hello_this_is_a_test_post/

But one good programmer in wordpress stackexchange advised me, Google treats - as word separator, but not _.

He also mentioned that rule doesn't apply for MediaWiki sites.

Is it true?

Solution

  • Google treats hyphens as word seperators is TRUE.

    The reasoning behind it I recall is based on programmers searching for functions which usually (if not always) have underscores in them. So instead Google treats underscores as word joiners.
