Hey everyone, I've noticed that some of my campaigns on Propeller ads don't spend as much as I'd like even with an average bid and large audience. It seems to depend a lot on the GEO, for example US always spends like crazy even with a low bid. But other countries that still have a fair sized audience (more than 10,000) don't spend my budget. Any thoughts on why this is happening?
It's likely related to your bid... others are bidding more and taking up larger part of the traffic. In smaller markets where propeller doesn't have that much traffic, it's quite common, it just takes 1 or 2 higher bidders to get large part of the clicks and there is not much left for the others.
It's also possible that the traffic estimator is not showing the right numbers, that happens a lot. So in reality, there is less traffic to be had.
Try to raise the bid to see if it helps, if not, the traffic is limited and you need to stay realistic with your expectations.
Well, there are a few factors that need to be considered.
First one is the competition.
The available traffic that you see is the traffic that is available for all and not only for you.
This means when there´s a high competition and more people want to buy the traffic it will be a smaller cut for everyone.
When you have high volume geos then chances are good that you still receive good volume but the lower the total traffic and the higher the competition the lower the volume that you receive.
The next thing is the bid, higher bids open more placements for you.
Often you just need to bid higher to get access to some placements.
Higher bids can also increase the traffic from the placements that you run already when you pay more than others.
But one very important factor is the creative CTR.
When your creative CTR is too low it doesn´t matter how high you bid, you won´t receive any traffic.
The trafficsources don´t only send traffic to the highest bidder, they send traffic to the people who get them the highest CPM.
Here is an example:
Affiliate A has a creative CTR of 2% and a bid of $0.04 CPC.
Affiliate B had a creative CTR of 0.4% and a bid of $0.10 CPC.
When the trafficsource sends 1000 impressions to affiliate A it would result in 20 clicks x $0.04 = $0.80 CPM
When the trafficsource sends 1000 impressions to affiliate B it would result in 4 clicks x $0.10 = $0.40 CPM
You see, even when the bid from affiliate B is 2.5 times as high as the bid from affiliate A the trafficsource would still make double the money on affiliate A so this is where they would send more volume.
In the end it´s not only 1 factor that decides how much traffic you receive, there are few factors to consider and when you have a good combination of lower competition, high creative CTR ad competitive bid you will receive most volume.
Ok thanks for the help guys. In this case, does it make sense to cut creatives with low CTR to get more spend?
Here is what I'm working with so far (iPhone sweeps cc submit offer in Italy):

Maybe cut out creatives 6183341 and 6183339?
Okay, I was wondering if the CTR is from traffic to lander or lander to offer on tracker so thanks for clearing that up for me. sorry I'll insert image correct next time
