I am running a campaign targeting a small demo (around 30k people) and click prices have been all over the place.
I am bidding auto CPM. I had my account under review and when they activated it, I was paying around 0.50-0.60 cents a click. I paused the ad and waited till the next day at 8am to run it. That was last Friday. Turned on the camp at 8am and got a ton of traffic the entire day, paying around 17 cents a click. I raised the budget and on Saturday I am now paying 0.50-0.60 cents again. I paused it and waited till 8am Sunday to run and now I am paying 0.80 cents a click??? Today I turned it on again and some ads were over $1.50 a click. WTF happened? My CTR is around 0.5-0.8 which is good?
Should I switch over to auto CPC? Manual bid CPC is showing range of 0.14-0.35.
Also when I raised the budget I got way less impressions. Maybe I shouldn't have touched anything. Damn
1) don't pause and play your campaign, you will get higher CPC by doing that
2) Auto CPM is good if you let it run for 3 days to let FB optimize it
3) For manual bid. I rarely do CTW campaigns. But I use website conversion, bid $30 (as facebook default) and the campaign run well I low down the bid.
What's your current reach? 30k is too small, and that's the only reason your cpc are going high after a day.
Yea, at 30k people, after spending say $100, you may have already hit most eyeballs > banner blindness sets in.
For tiny audiences you really need potent ads if you want them to live long, and <1% CTR doesn't qualify at least in the eyes of FB who want to maximise their EPM.
Of course, your conversion rates and revenues may compensate greatly, but I take it that's not the case.
What is a good ideal demo size for FB?
