Decisive: CPM vs SmartCPM (Volume Stops) (13)
I see everyone running SmartCPM and it seems like the efficient way to start campaigns but I have had much better results with CPM. When I run SmartCPM either my CPCs are extremely high or i end up getting no volume but by running CPM I could be missing out on some traffic due to high placement CPMs.
Does anyone know when the traffic from a placement slows down/stops because of it having no conversions? How does this relate to the CPA Goal?
I'm experiencing similar problem. Having SMART CPM camp on slowly growing CPM with CPA goal 0.51. Today I cloned it and switched to manual CPM, bidded $1,5 then $2 then $5 and almost no volume there with exact same targeting. Not even on $5 when my overall bid for Smart CPM camp is around $0.80?
Hi guys!
Smart CPM needs different amounts of exploratory time for different CPAs. For low CPAs it needs longer and higher CPAs it needs less time.
What amount of time/clicks did you allow it for the data collection period?
In my case it's 14000 clicks and 630 conversions at 0.51 CPA for that SMART CPM campaign. When I clone this campaign and use Manual CPM at $5 CPM I get very low impressions and changing bid does nothing.

I have a campaign with thousands of conversions where I am bidding a flat CPM.
The campaign is profitable and all looks good. However some sites I see I can just bid higher and get more volume since ROI is great.
The issue is that when I switch to SmartCPM CPCs go 3x-4x higher and eCPA 3x of CPA.
Since obviously the campaign has enough data, isn't there a way to just force the eCPA from going higher than the CPA I set?
I am targeting Malaysia with smart cpm. CPA goal is at $5.00. Target iphone and broad category.
But how come there's so few impressions/clicks? Almost 24 hours after launch, I only spent around $10.00 for 4 campaigns (each campaign budget per day is at $8).
Should i increase my cpa goal for smartcpm?
If I crease higher goals, will that increase my cost per impression?
Any help? Thanks.
Based on your win % it looks like there simply isn't that much traffic there. It's quite common in Asia for Android to predominate the market but you'd have to do some research - perhaps there just isn't much iPhone traffic in the targeting window you have.
Hi zeno,
When you see the win column, how do you tell whether it has good traffic or not? I still can't tell whether it is good or bad other than no conversions.
Thanks in advance.
I think he means whether there is a significant amount of traffic available for your targeting, not whether it is traffic that converts. In your case, you have won around between 25% to 50% of the total traffic for your targeting, so it means even if you win the total amount (100%) it wouldn't be that much traffic anyway...

If you had a 2% CTR that would give you 1600 clicks daily. With a $0.40 CPM that's $32 spend...
Let's say the offer has a payout of $0.75. If it converts at 5% then you're only going to get $60 revenue per day.
Ergo, that specific campaign is one with low potential for revenue or scale.
Hi zeno and ricmed,
Thanks for replying.
Sorry my maths not that good.
Just not sure how you come out with this numbers.
a) How do you see this CTR? I assume from
b) For the $0.40 CPM, how do you come out with $32 spend?
Thanks again.
a) I just made it up. You can see it at Decisive. Your CTRs are much lower....
b) $0.40 per 1,000 impressions. If you have 80 thousand impressions, 80 x $0.40 = $32.
c) 5% = 0.05 x 1600 clicks = 80 conversions. 80 x $0.75 = $60.
