Google announces Caffeine web search index

Search giant Google on June 8th (June 9th in the Philippines) announces the completion of a new web indexing system called Caffeine. According to Google, Caffeine was built 'to keep up with the evolution of the web and to meet rising user expectations.'

"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," Google software engineer Carrie Grimes posted at the official blog.

So this is why during the past few days, our post titles can be seen on Google search engine results pages (SERPs) just seconds after they are published. Feels like it's hours faster than before, which is actually best for search engine optimization (SEO). Google has an explanation.

"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," Grimes added.

Our source disclosed that 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.

Thanks Google...and good job!
