Anyhow, i will document my findings in more detailed fashion with separate posts – but something just popped up in my facebook ads account that made me think of this specific item:

What was it? This:

Facebook Ad CPC Too Low

So i see this message : 

Your bid on this ad may be too low. In order to get more impressions, we recommend that you increase your bid to at least $0.18. For more information about how bids work, please see our help page. Note that your ad is not paused and it is possible that you will continue to receive some impressions.

Now im thinking what, am i losing my mind? i know i read the minimum cpc is $0.01 – and i tried to set my ad to a 0.15 bid — but Facebook Ads is telling me no the minimum cpc for this ad is  $0.18. Now im guessing this has to do more with the history of the ad than any “system wide min cpcs”. But just as google loves to tell you the min cpc is 0.01, but you find me some terms that i can get an impression when my max cpc is at $0.01 (forget about a click…). Now i am almost sure that if i delete the ad (instead of lowering the cpc) and re-add it exactly the same – with a CPC of 0.15 it would have gone through and got impressions/clicks.

btw, since i was only lowering my bid to $0.15 & they only suggested a bid of $0.18  ”in order to get more impressions” & bec the ad was making money even at the old higher CPC i raised the CPC back up to $0.18. Although, i will be testing this in detail with other ads at which time i wont comply with their “suggestion” and see what happens. Ill report my findings here. 

This will be an interesting trend to track, if anyone gets this message when lowering a CPC or (gasp.) when starting a new ad – pls let me know in the comments.
