CPA Goal is an auto-optimization tool that helps driving conversions at the target price you set. The algorithm is able to predict what traffic slices are most likely to drive quality conversions at the desired price (slice=Zone+GEO+OS in Onclick and Survey Exit campaigns and slice=Zone+GEO+OS+Creative in Push and Interstitial).
It largely increases campaigns efficiency while saving the time you would normally spend analyzing and optimizing your results.

With the CPA Goal bidding enabled you will still pay for impressions/clicks, while the system will automatically optimize your campaign in order to deliver conversions with the CPA you set.

How does it work?

The testing period

CPA Goal is a new generation of auto-optimization tools, based on machine learning and big data. So each CPA Goal campaign goes through the testing period, during which the algorithm tests ad placements and analyzes their conversion rate (CR) data. The algorithm does it to set up an efficient CPM bid. That means, in real time, the system decides on the most effective CPM bid based on similar campaigns' CPM bids and expected traffic volumes.

Please note that during the testing period the cost of traffic per conversion may exceed the CPA Goal. Once this period is over, the cost will be close to the required CPA Goal.

Βid optimization and billing

Based on the test results, the system optimizes auto-bidding strategy in order to get conversions at the desired price, drive more relevant traffic and cut off inefficient traffic.

While called CPA Goal, the algorithm is actually built on the CPM/CPC bidding. This means that you’ll be billed by CPM/CPC but the system will select the most effective traffic based on the desired CPA.

The necessary traffic for your campaign is selected according to several factors such as GEO, zone, OS version, browser, and so on. The system does it precisely, so there is no need to manually remove poorly performing zones from your campaign (but you can still launch the campaigns with your black list).

Traffic price changes dynamically. So, if there are too few conversions from the zone, the system will place a lower bid on it and buy less of such traffic (or not buy it at all). Accordingly, if there are many conversions, the algorithm will place a higher bid to buy this traffic out.

Before you start

To start using CPA Goal you should check that your S2S (postback) tracking is set up. Without it the algorithm won't be able to get the conversion data.

How to set up and launch the CPA Goal campaign?

  1. Login to your PropellerAds account or register if you don’t have any.

  2. Click on the Create Campaign button.

  3. Enter your campaign name, choose Onclick, Push Notifications, Interstitial or Survey Exit ad format and CPA Goal as the pricing model.

4. Fill in your Target URL (for all formats) and creatives (for push notification or Interstitial campaign). Target URL is the landing page (or URL provided by a third party system) that users will be directed to.

5. Choose your GEO and set the CPA Goal (conversion price)

6. Fill in the details about your campaign's Budget

Daily Campaign Budget - amount of money you’re willing to spend per day on this campaign.

Total Campaign Budget - amount of money you are planning to spend on this campaign for the entire working period. If your campaign runs out of its total campaign budget, it stops.

7. Schedule your campaign

You can set the running period manually using the calendar or choose one of our presets: working days or weekends only. Also you can set up a time zone for your campaign according to UTC and choose the dates of the display period (start date and end date).

8. Learn your audience and target your campaign properly so it will work cost effectively.

You can target by:

  • Platform

  • Device

  • OS and OS version

  • Graphics card

  • Mobile ISP

  • Browser and browser language

  • Connection type

You can also include or exclude Ad Zones (if you already have collected some white/black lists), Subzones and Audiences.

9. You can also collect an audience for retargeting. More info is in this article.

10. Once you complete all the steps, you should check our Quality Guidelines and click on the Start Campaign button to send it to moderation or Save as Draft for later editing.

FAQ

What is the budget needed for a test period?

Advertisers usually allocate around $50 for tier-3 GEOs, $100 for tier-1 and tier-2 traffic in daily testing.

The bottom line is, test budgets depend on the offer and targeting. If there is concrete success data about the performance of the offer, many advertisers tend to just launch campaigns with unlimited budgets.

1. Difficulty of the funnel – the harder it is to convert, the bigger budget needs to be allocated in order to get proper testing and draw conclusions. Usually, ‘difficulty’ is reflected in the payouts, so you can use them as a guideline to set a proper test budget.

2. Traffic segment is what matters. The wider your targeting settings are, the more ad placements they include, the more budget testing will need.

3. Keep in mind traffic prices for the geos – whilst $50 may be enough in India, due to how cheap the traffic is, it won’t bring as much traffic in the US since the competitive prices are much higher.

How long is the CPA Goal test period?

You can expect it to last up to 24 hours. But it might require more time. Here’s why.

1. Your CPA goal (conversion price) and your budget affect the testing period and the amount of tested zones which makes your testing period longer.

2. Your funnel (easy or complicated) affects the testing period. Our system needs to get the information about conversions for proper optimization and traffic delivery. So the longer it takes for conversion to happen (deposits, cc-submits, etc), the longer your test period will be.

However, clicks are also used as an additional factor in auto-optimization. So campaigns with a complicated flow can still be successfully auto-optimized with CPA Goal.

Why is my conversion price higher than the desired CPA Goal during the test period?

The auto-optimization is based on the “click” and “conversion” information. To get this info our machine learning algorithm tests your campaign on the best traffic in the system.

1. There can be high competitiveness and higher traffic prices. This results in the CPA price exceeding your CPA Goal during the test. However, after the test period CPA will drop.

2. It may also happen because of your creatives’ or the offer’s low performance. Low CR and CTR lead to fewer clicks & conversions. The algorithm has to lower the bids and keep the test running, trying to get more conversions.

Try re-adjusting your CPA goal and work on your creatives to improve CTR and post-click activity.
