Piwik And Analytics together

Hi everybody,

I would like to know if it is possible to keep Analytics when using Piwik.
Does that alter results?

I use both Google Analytics and Piwik (both using asynchronous tags) without any evident interference.

Since they are each based on JavaScript tags, the only interference I would expect would be a slight extra delay in page-load times. But using asynchronous tags seems to minimize that.

I would really like to get rid of Google Analytics but it provides one critical feature which Piwik doesn’t: the ability to correlate keywords with pageviews-per-visit and length-of-visit. For my site, that is the best metric of keyword success, so I can’t quite get rid of Google Analytics yet.

Great, thank you for the reply.
I will try it to compare as well.
