Which one rank better with SE? green-diet or green_diet ? (hyphen vs underscore)

Hi, i wonder if this will affect my page ranking with SE?

should I use hyphen or underscore in naming my pages?

 

Use always hypens if you want keyword rich URLs. Otherwise using allinur:keyword experiment would show you the solution

 

I have already published all my underscored pages, how should i correct that?

 

frontpage has a function of editing ur links automatically on all webpages when u rename a file. u might want to try that. create a new web in frontpage (unless u are already using frontpage), den rename the files in frontpage. they will prompt u to update the hyperlinks.

 

I don't use frontpage..i use xsitepro

 

can i delete the files with my webhost and reupload the new files with hypens?

 

You will need to 301 redirect the old files to the new files.

 

I would go with the hyphen over an underscore anyday...and you can rename the files....the easier thing is to make sure you do it from the start from now on.
