Typically, this gives URLs like the following, telling the relevant script on a site to load product number 7. Search engines and users alike get no useful information about the content of a page from that URL. Compare that to this URL: But we can do more: Search engines can split that URL into words hyphens in URLs are treated as spaces by search engines, whereas underscores are notand they can use that information to better determine the content of the page.

Unfortunately, the last URL cannot be easily understood by a server without some work on our part.

Time for another example — we wanted earlier to be able to indentify this URL and rewrite it: That rule will now match anything in the parrots directory or any other directory whose name is comprised of at least one or more letters and hyphens.
