@tedster: Did you learn anything detailed about your zombie traffic? Any technical reasons why it was so unresponsive and poor for your site, for instance?
Whether it's intentional or not, google makes it hard to analyze. Zombies were never on for the majority of a day and the analytic tools I have work on a daily basis. Plus all of the "keyword not defined" stuff doesn't help.
As I've said before, the main thing I noticed just watching traffic was that the zombies were mostly informational queries. (Which is why I finally relented and split my informational pages to a sub-domain.)
I don't know about mobile traffic. I seem to get a lot of mobile traffic that converts (albeit with smaller sales), so I don't think that's it in my case. Sorry, but as with most things google, there may be no one-size-fits-all answer.
If zombies are real people, I hope that we can all agree that they are "mismatched" with the page/site they were referred to. Maybe mobile users to a non-mobile-friendly site. Or informational users to an ecomm page/site.
The question then becomes: "Why is google sending mostly mismatched users to a page/site for hours and days at time?"
