Okay, so here's the deal, I have a lot of websites and the +1 button works for every one of them, except one. Does anyone have experience of Google +1 button not working for their site. I mean, it shows and everything, but when I (or my visitors) +1 it, the button count is always staying on 0. I did participate in some +1 exchanges early on, but I ditched the effort, since i realized it could somehow blacklist my site. Can anyone tell me what should I do now?
