Backing up a Drupal site has always been a tedious process. I've just learned about an easier way.
I've added this site to Twitter at http://twitter.com/webmastertips.
Drupal has a Twitter Module, but it doesn't come with any documentation. This post is a first test of Drupal's Twitter Module on this site. If it works, I'll follow up on this post.
The old Drupalzilla.com site had a database of Drupal modules with tips for SEO. I've copied some of the information into the pages below.
The Spam Module filters content and comments for spam, as well as lets users flag contents for review by the administrators.
The Image Module allows users to upload images as nodes.
It creates duplicate content on sites—at least two duplicate URLs for every image node created.
The Forward Module adds a link to each teaser and full node that allows users to email the node to people.
The Abuse Module allows users to flag content as spam. It outputs an extra link at the bottom of teasers and full nodes.
The Tracker Module creates "track" pages for each user.
The Forum Module is part of Drupal core. If you enable the Forum Module, there are some things to be aware of.
Drupal's Paging Module is a popular way to break up nodes across multiple pages. This module does create some problematic SEO issues though.
