I recall that I could pause an experiment on Google Website Optimizer, but now that experiments have been moved over to Google Analytics, I don't see a way to do that (and knowing Google, there's a good chance that they just dropped that feature). Can anyone tell me how to accomplish this (short of changing the code on my site)?
It looks like the feature isn't available in Google Analytics at this stage - one of the few places it is noted is in this blog post:
... details that are currently not supported include copy a test and pause a test. Users only have the option to stop a test but, because this is a big problem for all users, I expect a quick fix after August 1. These exclusions could not have been a technical limitation but most likely were features that did not make the August 1 launch.
So hopefully it is coming soon. In the meantime you can stop the experiment, there doesn't seem to be any other work around.
