Pathauto is a module that automatically generates URL/path aliases based on categories, content types, dates, and more, instead of the generic “node/[nid]” format Drupal uses. Take advantage of tokens for fine grain control.
Path
Path is actually built into Drupal core and lets you define a custom path for any node. This is especially useful when converting a site and retaining previous URLs that are indexed and rank well in search engines. You can even add page “extensions”, like “.html” or “.php”, or even “.asp”.
Global Redirect is a utility module that helps avoid duplicate content which may get you penalized in search engines. The module works “out of the box” and requires no configuration, but you can tweak the settings if desired.
