Google’s search results change regularly, but with the impending rollout of Google Caffeine, there’s a lot of people wondering if that’s what the changes are. Google’s Matt Cutts told us today that Caffeine has not yet been rolled into the main Google.com search results.

Twitter has seen its share of questions about the Caffeine rollout:

There are even some tweets announcing that’s already launched or about to launch in a few days. When Google announced the Caffeine sandbox, the company didn’t give a firm indication when the testing would end and changes would be rolled into the main search engine. But, in reply to an email today asking if the Caffeine rollout has begun, Matt Cutts said “no.”

And when it does rollout, will it really change search results? Google’s announcement indicated that “most users won’t notice a difference in search results,” but “web developers and power searchers might notice a few differences.” ReadWriteWeb reported today on a study done by Summit Media, a UK-based online marketing company, which found that search results aren’t much different between Google.com and the Caffeine sandbox. The company studied 9,000 keywords and found that there will only be “a tiny change in ranking” after Caffeine, and that Caffeine seems to favor pages that are updated more often with fresh content.
