I am still unsure whether the site was hit by Panda or the ATF update, as traffic was lost on January 20th, which is extremely close to both ATF and Panda refresh. But here are the stats of 2 large websites, 1 hit by Panda, one not.
Panda hit site (25,000 - 30,000 uniques a day before, 15,000 after)
Bounce rate: 32%
Time on page: 0.45
Time on site: 7:45
Pages per visit: 11.36
Site not hit by Panda (80,000 uniques a day)
Bounce rate: 63.5%
Time on page: 1.52
Time on site: 3:35
Pages per visit: 2.92
I'm not convinced that user metrics are being used as much as some claim. But that is based off my own experiences. Improving user metrics had no effect on traffic for me.
