There was a noticeable drop in traffic to my information site on 30th November. Was there an update? Indexing issue seems to be solved, at least for my site. The newest post appeared on SERPs in a day and this time it did not disappear.

HUGE Drop in traffic today in Europe !

So far I’m seeing a global drop in traffic today, strange, no SERPs change I think!

I’ve had a few short burst of traffic today, at 2pm EST I was up >100% then down -10% at 4pm, back up >40% at 5pm. No real sign of anything special on my website, just the normal mix of users. This looks similar to a short burst I had on Nov 25 around 5am, with one notable difference 100% of 2pm traffic in a lot more user than 100% burst of 5am traffic.

25% drop in USA traffic today…Canada -20%, Australia -6%, UK +22%. I’ve gained new top three and top ten terms today, so why such a huge USA drop is mystifying.
