Google Analytics expands custom variable capabilities
Google Analytics now allows up to 5 custom variables to be set per page. This is a significant improvement and will make Google Analytics a much more attractive option to medium to large web business.
5 is still a bit limiting (Omniture allows up to 50), but overcomes a major blocker to using Google Analytics in the past. Interestingly, Google Analytics allows 3 different types of custom metrics: Page-level, Session-level and Visitor-level Custom Variables.
To test these out, I created a page name custom variable on each page. But more advanced implementations could include tracking by author, site section, logged in status, etc. Google Analytics just changed the game again with custom variables.






You can actually get more than 5 custom variables.
