Google Increases Their "Caffeine" Intake

Google has a team of engineers that have been secretly working on a complete over haul to their search index. Google calls this over haul their Caffeine update. If you'd like to try out the new version of Google's index you can get a preview of the results by searching at http://www2.sandbox.google.com and see how the search results will change over the next few weeks and months.

Users won't notice much of a difference to the way that the results page looks as this update is more about rewriting the infrastructure and core indexing code beneath Google's hood, so there are not so many changes for things like ranking. Some of the search results do change though so you should try out the preview to see where your website and your competitor website's stand in the results.
