Should I used Fixed CPM instead Smart CPM to get more traffic in this case ?
I'm running a smart CPM campaign in which I bid at the highest traffic possible, 0.6$ in the figure below
However my winning rate is only 15% and I get only 10k impression per day
How can I get more traffic in this situation? My winning rate is so low, that means other people are bidding higher than me ? How they can do that, there are some possibilities I can think of:
- They also use smart CPM and bid at the highest 0.887$ as indicated in the graph. However multiple bidding tutorials/posts on this forum recommend that in POP we only need to raise the bid to the point where increasing further doesn't result in a traffic increase, which is 0.6$ in my case.
- They are not using smart CPM, so the only other choice is the fixed CPM. I've never used fixed CPM before but I guess it must have some advantages over Smart CPM but I can't figure it out. Can I use fixed CPM in this situation, and if yes how can I use it effectively ?
If you really want to know there is no way around trying it 
What you can do is to setup a separate cpm camp and choose "distributed traffic" (check the box where you set day parting).
Then Propeller only will spend 1/24 of your daily budget per hour. So with this option you can limit your losses.
Disadvantage of CPM is that you will overpay for some zones. So be careful with your budget when you play around with it.
Other options:
If you have choice to open your targeting you might have access to more traffic.
The win rate itself of course depends on your bid and how many people are bidding with you for the same traffic slice / similar bid.
As larsometer suggested, if you want to know for sure, go ahead and try it 
But, any traffic estimator is just what it is... an estimator
The figures are never 100% accurate.Keep in mind that there are multiple people bidding for traffic and its in the best interest of any source to mix the campaigns a bit, they don't want to saturate their audience with just 1 offer or campaign, so they tend to mix things up instead of sending all the traffic to just one buyer.
So look at it this way, there are about 80k impressions sold at around $0.6 CPM, but it doesnt mean one buyer is getting it all at that price. And it's not $0.6 EXACTLY, maybe it's 0.61 or 0.62... try bumping the bid just a little bit, but don't expect to get all the 80k anyways.
There are more possible reasons to consider:
Your campaign settings might be limiting the impressions too. For example the daily cap... I didn't run POPs for a while, but with banner traffic, a tight daily impression cap can really limit the volume a lot.
How about daily budget? If a network tends to distribute the traffic evenly throughout the day (or if such setting is available) it will try to spend the same amount per hour, which can limit your impressions during the peak hours.
The settings of competitors can affect your impressions too.. there might be some that run campaign during specific hours, so your volumes might go down during those hours. Such "dayparted" campaigns tend to mess the estimators up a bit too as those tools tend to present averages.
And I could go on...
For the starters, I would try to bump the bid a bit to something like $0.63 to see if it helps any.
