Google has launched a site focused on providing support to those needing measuring their sites in a more sofisiticated way.
What can you find in Google Code? Lot of information about how to implement custom Analytics Installation on your site like “Change the longevity of your marketing campaigns“, “add a new search engine” to the list of those Analytics recognizes and “configuring tracking to use both Google Analytics and Urchin Software from Google“.If you are a Beta tester you can also find an entire section dedicated to Beta-testing event tracking. You can also find an E-commerce overview and E-commerce API reference. The sections “tracking code execution” and “how Analytics uses cookies” are just great.Great to hear that Google Analytics is getting smarter
