In August Google revealed the “next-generation architecture for Google’s web search” which the world’s been calling ‘Caffeine’. So they didn’t disrupt businesses over the holidays, Google did not plan on rolling out the new system until the end of this month, but with no official word yet, bloggers can only speculate as to whether the new system is live or not.
So what is Caffeine? Well, the new architecture is to include crawling, indexing, and ranking changes. What’s makes this different from the other changes, is that for the first time, Google provided a developer preview and asked webmasters a to try it out and give them feedback before it was launched. Caffeine won’t just be a set of new features, but is to be an entirely new search infrastructure that will replace the existing one.
In Google’s own words:
“The new infrastructure sits ‘under the hood’ of Google’s search engine, which means that most users won’t notice a difference in search results.”
So why do we need it? Judging by what Google have written, Caffeine is being designed to crawl the web more comprehensively, determining reputation and authority more effectively, and returning more relevant results quicker. If you notice changes on how Google has been indexing your search results over the last few days, let us know.
