Using hyphens opposed to underscores with in page URLs

Question

Someone told me the other day that Google likes url's with hyphens (e.g. a-page-title) opposed to url's with underscores (e.g. a_page_title).

Assuming this is correct is there a way to make Expression Engine use hyphens in it's page url's opposed to the underscores it uses by default?

Answer 1

Admin > Channel Administration > Global Preferences > Word Separator for URL Titles > Dash

Or, in your config.php file (or your bootstrap equivalent):

$config['word_separator'] = 'dash';
