Many of us are losing traffic. Maybe because there's a change in the way group boards are being treated. I was just checking my account analytics and non-groups have taken over the top boards that are showing my pins. And these non-groups are small (less than 50 pins, a few dozen followers). The group boards I used to rely on are being outshined by a long shot, something like 2xxxxx to 3xxxx impressions. My traffic is not going down. It's stagnating, despite my consistent pinning to group boards. But most of existing traffic are from pins that have already gone viral. Ultimately though, success in Pinterest is making your pins go viral. Hence, testing a pin's shareability is a must. I used to drip newly created pins on group boards over a couple of weeks and get an idea of their effectiveness. With these perceived changes, it's practically impossible to do that now. Read around online and some bloggers are observing that group boards with a few dozen contributors are seeing an uptick in engagements while boards with 500 or more contributors are being hit. What are you seeing in your analytics? Traffic?
