So I spent the afternoon, refactoring the variable names in my sites code (exciting stuff) and also adding some micro-format information to various pages.
Microformats provide consistant structured ways to tell Google, Bing etc about the types of information within your site. In my case, I've updated each of the sites 'manual download' pages with the ratings and product microformat. In addition I've added author information too these blog pages.
I'm expecting it to take a week or so for the changes to take hold, however it should provide everyone with clearer search information and hopefully drive content into the site. 77,000 free camera manual downloads and climbing :)
