SEO, Search Engine Optimization, is a method of writing pages in a way that search engines such as Google will consider your article worth the while. Often SEO merely involves sticking to a few simple rules. For contributors we have installed a WordPress plugin to help check all the rules.
Naturally, we want our information to be spread as well as possible. Sticking with the SEO rules is therefore very important. Better SEO means that your articles will show up higher in the search results. Showing up higher in the search results means more people will see our information.
As the SEO plugin is somewhat complicated, more experienced contributors will be asked to go through newly published articles and edit them. Often this will be as simple as breaking up long sentences, checking pictures for proper ALT-tags etc.
