But In the case of PHP, when you use this method to display something simple like the current page you are viewing, for example: I know there are better ways to do this, as stated just an idea. How does the search engine then see this as two pages? I thought that it would crawl your site and take the information about your pages and then store them or whatever. But this isn’t an actual page until it’s in action, so unless the crawler just so happens to see the page when someone uses it??

That way you'll always have the same link regardless of the way the content is displayed. Or have I missed something? :\ Would it not be better simply to have a form with a hidden ‘orderby’ field and POST the data so it doesn’t appear in the URL at all?
