Two new ways to get data into a GoodData project are posted on our user forums.

Google Analytics Export Tool - bring in your GA data and mash it up with any other source. We use this internally to track conversion rates (how many website visitors register for a free GoodData account).

Amazon S3 Bucket Integration - automatically retrieve data stored in an AWS S3 bucket. This is a good method to stage data and set up regular imports into your GoodData project.
