The tool provides an “assumptions” tab to let you edit the assumptions the estimates are based upon. This includes things like IT manager’s hourly wage, current email inbox size, how many spam messages an employee receives per day, how many people work on a team project, etc.

“Whether your company is big or small, brand new or been around for a while, this tool will give you a sense of the benefits of going Google in an easy-to-understand way,” says Vivian Leung of Google’s Enterprise team.

When Caffeine was introduced, so was a sandbox, where people could play around with Caffeine based search results, and get a look at how rankings were altered (if at all), and try to get a feel for how it was going to go. Now that sandbox has closed up shop, it looks like the Caffeine update will be live in Google search before too long. It will start after the holidays at least though.

“I know that webmasters can get anxious around this time of year, so I wanted to reassure site owners that the full Caffeine roll out will happen after the holidays,” says Cutts on his blog. “Caffeine will go live at one data center so that we can continue to collect data and improve the technology, but I don’t expect Caffeine to go live at additional data centers until after the holidays are over. Most searchers wouldn’t immediately notice any changes with Caffeine, but going slowly not only gives us time to collect feedback and improve, but will also minimize the stress on webmasters during the holidays.”

The announcement at what used to be the Caffeine sandbox reads:

We appreciate all the feedback from people who searched on our Caffeine sandbox.

Based on the success we’ve seen, we believe Caffeine is ready for a larger audience. Soon we will activate Caffeine more widely, beginning with one data center. This sandbox is no longer necessary and has been retired, but we appreciate the testing and positive input that webmasters and publishers have given.
