In this chapter we've looked at how you can add modules to your site to enhance search engine optimization. We focused our attention on the modules available free of charge through the official Drupal site.
This chapter identified the top SEO extensions for Drupal 7.x and described what they can do for you. We then showed you how to install and configure a specific set of those modules to create a solid foundation for your SEO efforts.
In the next chapter we will discuss what you need to do to get ready to launch your site; that is, the hands-on SEO work you should do in the lead up to launching (or re-launching) a site.
