I've been targeting a certain demo for a client for a little over a year and half now.
Up until last week my suggested bid was reaching $2.65-3.45'ish, and climbing! Now they're... $0.73-$1.05.
AWESOME!
... But WTF?
I don't get it.
Anyone else experience this?
No explanation but I hope your paid by CPA cause you profit will have exploded!
