The new web indexing system from Google, “Caffeine” is now up and running. Google designed the search indexing system over 13 months ago, in order to keep up with the huge growth of the internet, as well as to meet rising user expectations. According to sources, Caffeine offers up to 50 percent fresher results for web searches than the previous Google indexing system. Google also say that Caffeine offers more indexed web content than ever before.
Caffeine allows Google to index web pages on a much larger scale than before, allowing users to find information and new pages faster than before. The main difference, is that the old indexing system was comprised of several layers, which refreshed at a much slower rate because Google would analyze the whole web before a page would be made available to the searcher. With Caffeine, Google analyzes the web in small sections, and updates the search index on a regular basis.

According to the announcement, "Caffeine takes up nearly 100 million gigabytes of storage in one database and adds new information at a rate of hundreds of thousands of gigabytes per day."

What does this mean for website owners? The bottom line, is that your new content is likely to be found and indexed faster than under the old system. The mythical ranking algorithms remain unchanged though.
