It actually began late June 5, early June 6 and something that happened, at least to me, is that my peak traffic days have shifted, again.
Eons ago: Thurs to Sunday were the weekly peak traffic days.
3-4 years ago: Sat to Monday became the most trafficked days.
Last year: Sun to Tuesday was the peak.
As of June 5/6: Monday to Wednesday is the new peak, from Google.
Now, I know the entire internet didn't shift how often they use the internet on June 5/6, or likely any other of the times above, so something Panda can do is place your site on a different traffic "schedule". (unless Panda isn't the only "change" Google just made)
We've been thinking of rankings as static, you get x% of the searches for your keyword based on your rank, but that's NOT how the internet works anymore. The rankings are in flux depending on site type (informational vs transactional vs locational) and day of week, keep that in mind with any report you make here... please.
I think this may be relevant. It wouldn't explain traffic shaping to the degree some people are seeing it, but what if we're not only competing for rankings these days, but rankings at prime times of day and week? Like, the value of a TV ad spot goes up depending on the time slot. What if Google's starting to view the SERPs that way? Then their choice for #1 would get the top spot at the top time of day/week, and other top choice sites would get it during less prime times.
If that's the case, then one of my sites (which has not been hurt by any animal updates so far) has just recently developed an odd pattern with the number of Google searches I get per day:
Sunday, June 3: x
Monday, June 4: x-1
Sunday, June 10: x+98
Monday, June 11: x+98
I'll have to see how the rest of the week shakes out, but this struck me as very odd, those flat lines in almost exactly the same place on the graph.
I wish, too, that we knew what traffic shaping MEANS, and whether there's some action we should take when we see it happening. Whatever it is, I wonder if it happens to some sites we're not hearing from, because they come out of it with a higher level of traffic, so they don't feel the need to come in here and wonder what's going on.
