Inside SOOMLA: Ad Waterfall Analysis

Inside SOOMLA's Ad Waterfall Analysis - an invaluable took for publishers to optimize their eCPM

As a marketer for SOOMLA, I’m often disconnected from the customers / potential clients themselves. Much of my time goes towards content writing, web design, SEO, conferences and the tons of other micro tasks that arise. However lately I’ve found myself sneaking into some of the demos our sales team gives to potential clients because.. well, it’s amazing to see.

Each customer has their own current setup, pain points, ad revenue, integrations, in-app purchases, ad types but one thing I have consistently seen is the reaction from some of the capabilities that SOOMLA brings to the table. This is why I started the “Inside SOOMLA” series to show off a bit, but also to give a sneak peak into our system for those who have yet to sign up and request a demo (which you can do here… shameless plug).

One of the most common scenarios that we see are app publishers leaving money on the table. There are a number of ways that this can occur, however specifically let’s look at the “Ad Waterfall”.

What is an Ad Waterfall?

Also referred to as daisy-chaining, simply put, the ad waterfall works as a prioritized series of ad networks or exchanges arranged from top to bottom in order of performance set by the publisher. The performance tends to be based upon the network’s history of payouts (eCPM), their fill rate, latency delays when serving ads and many more other potential reasons.

To gain some context on what makes the ad waterfall so important, we recently published a monetization benchmarks report which specifically looked at the importance of first impressions. TL;DR – Advertisers payout exorbitant eCPMs for first impressions as they understand their importance.


Waterfall Analysis Screen

The entire purpose of this feature within SOOMLA is to give publishers the ability to make more data-driven decisions rather than biased ones. Publishers often times have a strong biased towards one ad-network since they see a higher eCPM coming from that network however this has been shown to be misleading. The position of the ad network in the waterfall often dictates the higher eCPMs and not necessarily the caliber of the ad network.

There are however other key features of this screen. By giving publishers the ability to visualize the data, they can make data-driven decisions towards changing up their ad-network mix, as well as helping to leverage this information for more beneficial discussions / negotiations with the ad networks. How is this all achieved you ask? Here goes…

Feature 1 – Ad Networks per Impression

This particular section shows full details about what is happening throughout the first ten impressions broken down by ad-network. Publishers see the number of impressions, the total revenue generated by that impression and the current eCPM, all broken down by the impression # in the ad waterfall.

Feature 2 – eCPM Decay Chart

What publisher wouldn’t like to know if they are achieving the optimal eCPM and not leaving money on the table? Thanks to this feature, publishers are now able to see just that. For the first ten impressions, publishers are displayed the “Actual eCPM” (the average across all selected ad-networks) while the “Optimal eCPM” represents the maximal eCPM attainable for the given impression by one of the ad-networks. For a more in-depth explanation about eCPM Decay, check out one of our posts on it.

Feature 3 – Ad Network Comparison

This section visualizes for the publisher which ad-networks serve at which impression and how many ads they server daily. Furthermore, you can see exactly the eCPM paid by each ad-network for each impression count.

This is an invaluable tool in conjunction with the eCPM Decay feature as it allows you to break down why certain ad networks, while having higher eCPMs, are not displaying more ads as I’m sure publishers would like them to be. Low fill rate or bad choices vis a vis the mediation are often the culprits here.

Our Ad Waterfall analysis feature is unique to SOOMLA and one has one of two effects on potential clients of ours: 1) They are amazed and want to see a direct business case via their data, or 2) The stream of questions comes, asking how we achieve this, is the data credible and so on.

If you have any of these questions, or want to see a far more in-depth demo of SOOMLA (not just the Ad Waterfall feature), reach out and we’ll get one set.
