Today, Google officially announced their new search index, Caffeine. Caffeine is a push to keep up with the most relevant, rich content for the user. The new Google index will be searching for regularly updated content, video, images, real-time information, and anything else that can provide a better user experience. Here’s an excerpt from the Google Blog on the difference between the old and new index:

“Our old index had several layers, some of which were refreshed at a faster rate than others; the main layer would update every couple of weeks. To refresh a layer of the old index, we would analyze the entire web, which meant there was a significant delay between when we found a page and made it available to you.

With Caffeine, we analyze the web in small portions and update our search index on a continuous basis, globally. As we find new pages, or new information on existing pages, we can add these straight to the index. That means you can find fresher information than ever before—no matter when or where it was published.”

Google is continually updating their index and algorithm, looking for improved methods. From a search perspective, this simply means – give the user the best experience possible and you’re also serving the engine.
