FB CTR based price adjustment mechanism?
I have done some small time experimentation, the last one was for a novel physical product (yea wasn't really looking for roi is this experiment)
I'd appreciate any insights into their cost adjustment machanish, the FB version of Gs quality score.
Initial Suggested Bid was .50 to .60 tried .20 bid (heards suggested was BS)
In < half a day it hit my $4 daily budget and stopped with
152,794 imp, 29 clicks, giving a 0.019% ctr.
Raised the daily limit to $10, got no new impressions for > 6 hrs
******
This is the curious point it completely stalled after hitting the daily limit to first time and couldn't bring it back to life.
Does raising the daily limit mid-day not unpause things as expected?
I'm wondering if there's an elapsed time factor in their Suggested Bid adjustment that continued to raise it during the couple of hours the ad was paused at the daily limit.?
******
After 7 hours a new ad was approved, it got 55 imp, no clicks, the original one got 13 more imp. (still with .20 bids) then it all stopped again.
Upped bids to Suggested .52
Tried a couple of higher bids, still got no impresions for 2 more days.
Suggested Bid: went from an initial .50-.60 to a final 1.13 - 1.33 USD when i shut it down.
Sorry if I dribbled too long...
