Google Caffeine

Google caffeine was under development for the past few months. It is a major update to Google infrastructure and includes no UI changes. 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. Most users won’t notice a difference in search results, but web developers and power searchers might notice a few differences. Google caffeine had been tested by many webmasters and it received positive feed backs. First it will be tested in one data center and later implemented in other data centers. The new Google caffeine will be

• Fast.
• Relies more on keywords.
• Improve indexing speed, accuracy, size, and comprehensiveness.
• Search is moving into real-time. News, information and social media results are set to be boosted by Caffeine, with this all being part of the large effort to make real-time search a reality.
• Crawling and indexing may change.
• Powerful, flexible and robust in the way pages are indexed.
• More importance will be given to the exact matching domain names.
• Local results even if you are not logged in. Your location may be detected based on the IP address or ISP.
• Caffeine provides 50 percent fresher results for web searches when compared to the old search.

Tips for webmasters

• Rankings are unlikely to fluctuate.
• Keep your site fresh to be crawled by Caffeine. If your site is not updated regularly you may lose your rankings.

Googles New Search Engine Index “Caffeine”

 Google has just unveiled a “secret project” of “next-generation architecture for Google’s web search“. This new architecture appears to include crawling, indexing, and ranking changes. For the first time, Google isn’t simply incorporating these changes into their existing infrastructure or replacing it. Instead, they’re providing a developer preview and are asking webmasters and power searchers to try it out and give them feedback. Unlike Google’s now-defunct Search Mash, which was intended for search experiments that wouldn’t necessarily be incorporated into Google’s main web search, the caffeine index seems to be an entirely new search infrastructure that will replace what exists now.

Based on the blog post, we can guess that this new infrastructure may include ways of crawling the web more comprehensively, determining reputation and authority (possibly beyond the link graph and what’s typically thought of as Page Rank), and returning more relevant results more quickly, although Google’s Matt Cutts told me that the changes are “primarily in how we index”.

While the biggest visible changes in Microsoft’s relaunched search engine, Bing, are user-interface related, Google’s new search is only infrastructure related and includes no UI changes. On first glance, however, the underlying infrastructure changes do seem to have impacted user interface as it relates to universal search (likely because universal results are influenced by ranking and relevance signals). For the sample searches I did, the first ten results were fairly similar, but the existence and location of images, video, news, and blog posts was notably different.

A search for on the new infrastructure, for instance, returns video and news results midway down the page.

A search on the existing infrastructure, however, returns news at the top, video in the middle, and images at the bottom of the page.

Undoubtedly, Google Caffeine will cause quite a kerfuffle in the web developer and search engine optimization world and many will dive in to try and figure out the changes. We’ll likely see many a speculative blog post about how best to optimize for the new infrastructure, but my guess is that it likely does what Google search does, but better. And the foundational elements of having a crawlable infrastructure and compelling content remain.
