So I thought I'd look at those bumps and see which areas of the site are specifically being "tested" by Google on those days. In particular it does seem that our forums come off badly in the metrics. Time on site only at about 1 min for traffic landing there (compared to other areas where it's more like 5 minutes). And pages/visit also well below site average.
Forums specifically have a hard time absorbing any traffic bumps, not the least because for any meaningful engagement the visitor needs to register (if they aren't already). If they are still finding that forum site via Google, then it's almost a guarantee that they aren't registered yet. So, a forum site can only grow slowly in time, regardless of any sudden traffic increases. If Google engineers spent any time whatsoever analyzing the results of such stress tests, I think they would find that they are not working well on forums.
You have to be proud of your time on site. Mine averages in only 24 seconds. I have obsessed about it before but it has been stable like that for years, all through various Pandas (except 21.5 of course). Besides, I find that I can get in and out of most sites these days in under 10 seconds myself. 5 minutes visit is incredibly long these days, what are they, falling asleep mid-page?
What kind of time on site do you all see specifically for traffic coming in from Google?
But Google's traffic is the worst among major SEs and averages at under 20 seconds. The only traffic that's worse than Google's is from large ISP affiliated search engines - AOL, Comcast, Verizon and the like, each powered by different major SE.
