Google Caffeine

Earlier this month, Google invited the public to take their next generation of web search, code named Caffeine, for a test drive.

According to Matt Cutts of Google, Caffeine is essentially a rewrite of the search index and it roughly compares with the Big Daddy index of late 2005/2006. In other words, it's a BIG change to Google search.

Here's a couple of grabs from Mike McDonald's video interview with Matt Cutts on the subject:

"We're shooting to get results identical to previous version. We'll open up a few datacenters with it first and then roll it out."

"Caffeine will be more powerful, flexible and robust - allowing Google to index faster."

"(Caffeine) builds a powerful foundation for including any changes we want to do with indexing. Not so much for taking advantage of semantic, real-time indexing, but for getting good infrastructure in place for growth and unlock more power."

"Webmasters shouldn't be concerned. Caffeine does not affect your site architecture".
