I've been seeing more random international clicks coming through to 528 clicks today, out of around 14k. I can live with the 4% although I'd like not to. Good to see people putting it back out there in the open.
Application traffic is really killing me right now. Seeing 5x less conversions with a app referral than with regular facebook browsing. Shitty, especially when 1/2 of the traffic right now is app.
I wish Facebook would give us an option to disable Application traffic.
I'm already paying high CPC rates for this specific campaign (>50c, my ctr is 0.01%-0.02%; don't ask lol), and my ROI for facebook.com referral is 300%. So even if I did have to pay more, it would still benefit this campaign.
