Drupal Modules You Should Know About

This is a list of Drupal modules that are pretty much indispensable to me. If it's in this list, and you make websites with Drupal, then you should probably know about these.

Global Redirect

Essentially makes sure that each page on your site has one and only one URL that points to it, which can be important for SEO.

Markdown Filter

Implements an input filter for Markdown, which is a kind of shortcut language for generating HTML.

Mollom

Spam-blocking for all of your content on a Drupal site, including your comment forms, contact forms, sign-up form, etc. And, it does so without having to resort to making visitors fill out a CAPTCHA (most of the time).

Page Title

Gives you better control over what goes in the <title> tag of your pages.

XML Sitemap

Automatically builds a sitemap for you, and optionally submits the sitemap to a number of search engines. Sitemaps are used by Google and other search engines to more efficiently crawl your content and display search results.
