One of the things I like about both Drupal and WordPress is that creating SEO-Friendly URLs is very easy. Instead of having your URL be http://www.mysite.com/page/1 (or worse, http://www.mysite.com/PageServer?id=1), you can have http://www.mysite.com/page/seo-friendly-url
With WordPress, it’s basically out of the box with permalinks, though I don’t usually pick the default format. Drupal requires an additional module called pathauto, but once you add it, it works pretty painlessly. I’m sure there’s some tweaking involved somewhere, but it works fine for me on a few Drupal 6 and Drupal 7 sites.
Working with Rails, it’s not quite as easy. I’m using ActiveAdmin as a back-end (instead of ActiveScaffold or RailsAdmin), so I wanted to make sure anything I picked would work with it. Friendly_id was my first choice after taking a look at a few contenders.
Installing it was pretty straightforward, just following the directions, and adding a new migration for my “slug” column. In Friendly_id, slugs are tokenized versions of any other column, in my case name. Ran into one weird problem by not specifying the exact version of the gem in my Gemfile, but once I added that, things worked.
One nice thing is that I didn’t have to muck with my routes at all for this to work with Rails 3.1.
