Recommended Drupal modules for SEO

Pathauto Module: The Pathauto Module creates custom URL aliases based on configurable rules.
Global Redirect Module: The Global Redirect Module automatically redirects Drupal's internal URLs (e.g., http://example.com/node/123) to their URL aliases.
Page Title Module: The Page Title Module allows you to create cusom <title> elements for each node (page) of content.
Front Page Module: There are several ways to make a custom front page in Drupal, but this is the easiest one. Making a custom front page helps prevent duplicate content problems. More about that later.

Content Construction Kit (CCK): This module is one of the reasons that Drupal is great. Drupal provides several basic content types like "page", "story", "blog post", "forum post", and it gives you the ability to create new content types. The CCK module takes it a step further by allowing you to add custom fields to your custom content types (beyond the default "title" and "body"). A CCK tutorial is coming soon.
Views Module: The Views Module allows you to list nodes (pages) in custom ways. For example, if you created a custom content type called "business" for a business directory, you could use the Views Module to display lists of businesses in various ways. You might choose to list 25 business per page, or maybe a photo gallery of business photos arranged in a grid pattern.
