I'm looking for an app that would pull data from multiple different google analytics accounts for multiple different websites and show key information (like #visitors/day, #uniques/day, etc) in a "dashboard" kind of way -- so you could see how all your sites are doing at a glance without having to click in and out of lots of different sites and accounts. Does anyone know if anything like this exists? If it doesn't, if I built it would anyone want it? I can't be the only person with 100+ websites to keep track of...
You can do that by using your own open source analytic application on your webserver. It is like those CMS which are installed on your webserver for websites. There you just need to add code on your web pages and you will get detailed reports. For example PhpMyVisites is the best one. Now they are upgrading it to be an alternative for google analytics. check out their official website. I am using its old version which is still the best. Gives you all the details you would want. You can trac your partners traffic, newsletter traffic, etc
