Okay, I've been running a set of campaigns for about 3 months now consistently. On average I've been paying about .30 to 35 per click for all of my keywords. Well, all a sudden this 2 weeks my click prices have started to decline. Daily CPC prices 1-Feb tue $0.35 2-Feb wed $0.37 3-Feb thu $0.20 4-Feb fri $0.19 5-Feb sat $0.18 6-Feb sun $0.20 7-Feb mon $0.20 8-Feb tue $0.20 9-Feb wed $0.19 10-Feb thu $0.20 11-Feb fri $0.19 12-Feb sat $0.17 13-Feb sun $0.17 14-Feb mon $0.18 15-Feb tue $0.19 16-Feb wed $0.11 17-Feb thu $0.08 Can anyone explain this. I've not done anything differently in my account. Everything has been the same for the past 3 months.
