The XML Sitemap module is another one of the best Drupal modules for SEO out there. It makes generating, maintaining, and submitting your site’s sitemap to all of the major search engines a breeze.
The XML sitemap module allows you to setup configuration options based on each specific content type or even each specific piece of content on your site. This module provides you with a field for each content type or piece of content that allows you to rank the priority of that content to be displayed in your sitemap; rating from 0.0 to 1.0 with an additional option to completely leave out that content from your sitemap.
The XML Sitemap module gives you a couple options for how it is generated. You can allow it to be processed whenever the cron is run and limit the number of entries that are generated on that cron. This can be helpful for larger sites that need to generate their sitemap in batches so it doesn’t overwhelm your server. The XML Sitemap module also allows you to setup settings specifically for your homepage and also dynamically give content on your site additional priority based on whether or not it has been promoted to the front page of your site and the number of comments that piece of content has.
The final set of options XML sitemap gives you, and why it’s one of the most convenient and best Drupal modules for SEO, is that it can handle the submission of your sitemap to a handful of search engines all on its own. You can select how often the sitemap is to be submitted and select which of the search engines you want to submit it to (with your current options being Ask.com, Google, Moreover.com, Bing, and Yahoo!). There is also a button that when clicked, will automatically submit your sitemap to any one of or all of the search engines you wish to submit it to at that moment.
So now that you know that the XML Sitemap module is one of the best Drupal modules for SEO, go out there and add it to your site!
