Wordpress tag: Do you use "_" or "-" ?

When you join 2 words together in wordpress tag, do you use "_" or "-" ? Any differences from the seo point of view?

For example: online_game or online-game?

 

Shouldn't matter from an SEO standpoint. Use whatever you are most comfortable using.

 

I think "-" is more favorable. Then again, even sites like Wikipedia use underscores.

 

Domain don't really matters in SEO point of view any more. I do find - more user-friendly than _ since I would not have to press down my Shift button.

 

markn26 is correct, dashes are better, see searchenginejournal.com/google-underscores-hyphens/6010/

 

It doesn't matter SEO wise but my personal preference and for users "_" is better.

 

It doesn't matter, I use - instead of _ but that's just my preference.

 

me too think so

 

i use - for the tag.
