I have been wondering for quite some time what effect page naming has on SEO. Lets say you have a website http://www.xxx.com/ Which one (if any) page naming standards does Search Engines Prefer? http://www.xxx.com/Free_Quick_Download http://www.xxx.com/FreeQuickDownload http://www.xxx.com/Free-Quick-Download This of course assuming that other Keyword/meta/header work is done. Will search engines care of how a page/directory is named?
