Google Caffeine: The new Search engine index
Google announced launch of it's new search engine this June 2010. It's time to be happy for all those who update their website contents frequently and willing to appear in Google search as soon as they publish. Google has made this possible with it's brand new search engine index.
The new search engine Caffeine is Faster, Accurate, Relevant and with huge index. It also means that websites and contents which were holding hire positions in Google will be punished somehow and black-hat SEO tack-ticks will be found and punished much faster now.
Following screen-shot describes it's effect on Blogs@DiGiTSS; we are happy to know that impact is positive if one updates content frequently. (The large red-dot represents period when Caffeine went live)
If you are not updating your blog frequently it's alarm to wake up..! 🙂
Today this is 100th post for Blogs@DiGiTSS and I want to confess that we are not able to update it as frequently as possible and not able to push up every idea and thought on this blog as we wanted. But I am sure introduction of Google Caffeine will boost our blogging rate..! Hope that works for you too.
I would like to highlight and emphasize some statements from The Official Google Blog here, read them carefully, it would introduce you to some facts if you haven't read that already.
Today, we're announcing the completion of a new web indexing system called Caffeine. Caffeine provides 50 percent fresher results for web searches than our last index, and it's the largest collection of web content we've offered. Whether it's a news story, a blog or a forum post, you can now find links to relevant content much sooner after it is published than was possible ever before.
Some background for those of you who don't build search engines for a living like us: when you search Google, you're not searching the live web. Instead you're searching Google's index of the web which, like the list in the back of a book, helps you pinpoint exactly the information you need. (Here's a good explanation of how it all works.)
So why did we build a new search indexing system? Content on the web is blossoming. It's growing not just in size and numbers but with the advent of video, images, news and real-time updates, the average webpage is richer and more complex. In addition, people's expectations for search are higher than they used to be. Searchers want to find the latest relevant content and publishers expect to be found the instant they publish.
To keep up with the evolution of the web and to meet rising user expectations, we've built Caffeine. The image below illustrates how our old indexing system worked compared to Caffeine:
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.
Caffeine lets us index web pages on an enormous scale. In fact, every second Caffeine processes hundreds of thousands of pages in parallel. If this were a pile of paper it would grow three miles taller every second. 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. You would need 625,000 of the largest iPods to store that much information; if these were stacked end-to-end they would go for more than 40 miles.
We've built Caffeine with the future in mind. Not only is it fresher, it's a robust foundation that makes it possible for us to build an even faster and comprehensive search engine that scales with the growth of information online, and delivers even more relevant search results to you. So stay tuned, and look for more improvements in the months to come.
So don't be surprise if you see your recent twitter update right on top some day while you're searching something..!
