Google Caffine’s Jolt to the SEO System

Google has announced that it has Completed the roll out of the new web indexing system, codenamed ‘Caffine’. Caffine is designed to give 50% fresher results, meaning that it will see changes to the web faster. So whether it’s a news story, a blog or a forum post, the web page should appear in Google search results sooner than before, offering more real time and faster updates.

A public test of the new caffine search engine was rolled out in a single data centre in August last year (link to a news article about caffine) with wider deployment from November. With this announcement from Google we can presume that Google has completed the rollout to all its data centers and the new Google Caffine index is now being used in all searches worldwide.

The change has been made necessary by the speed that the web is growing. With wide adaptation of websites writing their own news items, their own blogs and adding more media based content (like videos, video blogs and you tube channels) changes were required for Google to keep up. The old engine was split into layers with main layers taking two weeks to update, but Google Research head Peter Norvig has now said "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."
