Another slow starting week. I've noticed my Yahoo and Bing referrals are way up, to nearly 50%, Google is dropping fast. Same situation here, serps "look" ok (signed out, no plugins) yet Google traffic is few & far between. I'm not even worried about conversions anymore, we need traffic first.
One other anomaly in GA, a little over a week ago, my 30 day traffic trend was + 5% (the green/red text next to your selected account when logging into GA) a day later it was 56% and a day after that it's 100% in the green. HOWEVER, when you look at the chart, it's dead flat. Today it's showing + 102%. It's just another clear indication that either I'm misinterpreting the obvious or Google Analytics is broken.
BTW, Piwik does not concur with GA's cheery assessment of my traffic trend.
