For some odd reason every time I duplicate a campaign it's CPC is always ends up being a lot higher (targeting is untouched). CTRs are pretty similar to the original campaign yet CPC remains high.
Anybody have any idea what's going on?
I have noticed this as well. Although not always, but often this happens. If you check the stats the reason is because CPMs for this adset are also higher.
Its either because FB shows the ad to a different subset of users or shows it in a different impression slot. Also check your relevance score, if mine drops by 1-2 points, the costs go through the roof.
Solution would be to use FB pixel and run not cpc campaigns but optimized towards conversions. Or clone many times and leave only those that start with low cpc, kill all other adsets.
Another point I noticed is if there is a lot of negative feedback, the costs could go up, as relevance score goes down. So no matter how many duplicates you make, they all have high cpc. But this seems to be affected only on campaign level, so making another campaign could help fix this.
If you're not launching at midnight they will mostly always be higher.
Midnight is not too big of a deal.
If your running out of audience reach then it will be higher for sure.
If you notice a huge difference just delete that one and clone it again. The next ad could be much cheaper, it's hard to predict...
Personally I clone it more than once right off the bat, and delete the ones with a high cost and keep the low cost ads
Also to weigh in, I have some adsets whose CPCs will be twice what other adsets are, BUT the cost conversion is still lower (targeting seems to be better). So keep in mind the EPC each adset is getting. Best of luck!
Do you guys keep the interest/targeting same on duplicated adsets?
