I'm not seeing any changes in my niches. West Coast US, informational sites.
Not really seeing a LOT of increase in traffic though (weekend?) despite some new top 3 ranks.
Maybe, maybe not. I have a site that's been #1 for several phrases consistently for years. Despite this, a decrease in Google traffic of around 85-90%. No ads above it, nothing like that. It's like people just aren't searching the term.
And ironically, none of THOSE URLs are the ones I got sent a "big drop in traffic" notice for in WMT. No, that was one was a term that had actually shifted in rankings and seen maybe a 30% decrease in clicks.
