Using statistics to improve the usefulness of our sites
One nice thing about publishing documentation on a Drupal or WordPress site is that it is easy to instrument the site to find out which which topics are being read and searched for by the users. Here is what we have seen in the last few month's activity on our content-rich model sites.
We have seen daily search requests from people looking for samples and examples. Both the garage and grocery shopping topics are popular.
People are interested in the basics of getting started with DITA. The various planning, tutorial, and "how-to" topics are also popular.
More advanced users look for technical information and examples on XML, the DITA Open Toolkit, Python programming, and the Drupal publishing and blog APIs.
We restructure the sites periodically to make it easier for users to find the topics that are the most useful to them.
