I get asked this question every day “Is Google caffeine live or was it a publicity stunt?” The honest answer is that I don’t know. I am however beggining to believe what I am reading in forums such as the thread at Webmasters World that indeed Google caffeine is live. Here is a little taste of what people are saying.

FWIW, I’m doing slightly better in main SERPs now than I was before the rolling update. And while it seems trivial, my traffic is way up, and converting well too.
Relative to the main SERPs, I’m barely up or down in the Sandbox. However, looking at the results, there are less amateur sites in the mix, and sites seem to be rewarded for what I would call “structure”.

I’ve already mentally moved away from thinking the sandbox impacts SERPs, or that direct inferences from one can be applied to the other, now or in the future. As far as I’m concerned, the Caffeine architecture was “on display” in the sandbox, and will be eventually underpin the main results, once the infrastructure investments are in place.

As an off the wall suggestion, the dataset fold-in could have been G figuring out how to utilise both architecture/infrastructure set ups (caffeine and decaff) within one dataset, rather than as discrete entities. This would allow incremental datacentre upgrades without any perceivable disruption to main SERPs.

and another post…

Just did a test search: I got slightly different SERPS, but not more different than if you sometimes hit another server (eg. when using a different geolocation IP).

This time the www.google.com gave me six more images and one more video than “sandbox”. The top 3 listings are identical, then 2 videos on “sandbox” compared to 6 images+three videos on “google.com”.

Between the two, only 3 listings are changed in the top 10 – one change is due to images/videos replacing a text listing.

The “Show options” tool to the left stays the same, and the drop down search box with the large text is also the same.

This minor difference is probably related to hitting another datacenter. Search quality is very high, both for text, images and video, meaning that results are not only relevant, but spot on.

So my question is what are your thoughts is Caffeine live, Was this a publicity stunt. Is Google giving you the silent treatment again?
