    The world is your oyster. The sun is shining, the birds are singing and you’re ready to start your digital marketing journey. Then, something weird happens that promises to leave you feeling sick: you’re assaulted by an array of utterly complex acronyms and abbreviations. Trios of letters such as CPA, CPI, CPL, CPC start haunting you in your dreams. It’s enough to make your head ache for a while, am I right?

    No worries! Your troubles will soon be gone! Guess what? This article has a clear objective: to define, differentiate and explain in as detailed a way as possible one of the terms that you’ve surely been attacked by: CPI, which means Cost per Install.

    This specific term deals with the model of cost calculation that will be considered in the contract you have with the advertiser, which is the company that owns the offers. On a CPI basis, you'll be compensated per each install.



    Cost per Install – CPI

    As you may have already guessed, the CPI model deals mainly with apps and games. To put it as simply as possible: each time an app is installed, you get paid. You’ll see that it’s not as straightforward as that and that advertisers are always making demands and imposing tougher regulations to this model.

    Most CPI offers promote free apps. Wondering how that’s even possible? The advertiser is paying for an install that was free. Does that really mean he didn’t get any cash from it? Well, yes. Nevertheless, that’s obviously not the whole story, or else you could say that advertisers are not being rational, and this is surely not true.

    The thing is: advertisers need volumes, especially at the beginning of new campaigns. This means that an advertiser’s first concern is obtaining the highest number of installs possible. Why? Because he already knows that only a fraction of the total number of installs will become active users and an even tinier fragment will become actual, trustworthy, paying users. What does that mean? It means that, the higher the total, the higher the advertiser’s probability of acquiring more paying users. Simple math, right?

    Advertisers are always concerned with the churn rate. This is the rate in which customers leave a specific service. This is true for both models alluded to in this article, but it’s even more relevant for CPI, since it translates to the proportion of users that install the app but never become active. This term is actually the main point behind the explanation I gave in the previous paragraph. Due to the fact that’s such an important parameter, we’re proud to offer you the highest quality traffic possible, which implies lower churn rates.

    There’s another step after the user becomes active: ideally, he should become a paying user, which is the guy that makes in-app purchases. This is the one that’ll make the model worth it and, for the advertiser to be profitable, he has to compensate for all the others that installed for free and didn’t generate revenues at all. Do you know what that means? That both margin calculations and breakeven points have to be sharp!

    Another way an advertiser can make money is by promoting other apps in his own products. In this specific case, he’d take advantage of the traffic he has in order to gain money advertising other apps that can either be from his own company or from third parties.

    Furthermore, here’s another acronym for you to become acquainted with: ARPPU. This funny-looking group of letters stands for Average Revenue per Paying User. This is a crucial parameter because, when considered along with the users’ retention periods, it gives you the important LTV, the lifetime value. The latter is the essential element you need in order to be able to measure real performance on both models – even more relevant on CPI. At the end of the day, you can never forget about an advertiser’s main concern: guaranteeing their LTV is higher than their CPI. This is the holy grail. It’s what successful campaigns are made of.



    Traffic Quality - CPI

    It's important to understand that CPI is quite susceptible to fraud, especially when considering free apps.

    Why? Well, as you may have guessed, there can be some dishonest people that make use of bot traffic, for example. How? By setting up a “robot” – hence the term bot – that keeps installing the app over and over again, as it will gain from each install. It’s a brilliant idea, right? It can be, but only for a short period of time. Sooner or later, the advertiser will realize something’s up: he’ll see thousands of offers that don’t bring active users and he’ll also analyse IPs. That’s when it hits him. He knows what’s going on. It’s fraud. Remember the churn rate? Yup. His rate will probably go through the roof!

    There are other forms of fraud on CPI, such as forbidden traffic, which has a lot to do with incentivized traffic. This kind of traffic comes from users that will gain something by performing an action. For example, if he or she installs your app, they’ll win some benefit in a game, such as lives or a special item. This kind of traffic is considered to be of low quality, since the user will usually perform the action just to gain the benefit and then leave. This is why advertisers don’t generally allow this practice.

    Due to this greater fraud vulnerability, business models on CPI are becoming stricter. Now it’s common to hear the terms CPI + KPI or CPI + CPA as cost models, where you have to combine the install of the app with some performance indicator. In the case of KPI, Key Performance Indicators, it can be something like reaching level 10 in the game in the first month.

    This is a way advertisers have found to protect themselves against low quality traffic. It’s simple to grasp that the costs of these kinds of models will be higher than the standard model, in which the user just needs to install and open the app for a conversion to be accounted for. If you can choose, the standard model is obviously the best choice. This is not to say that the other cost models can’t be profitable, particularly if you’ve got a very good offer. Even so, it’s definitely harder to make such models get those huge profits you know you love!

    You’ve read the explanations. You’ve been taught this very important term and have been able to grasp the meanings.

    You’re ready to go for it! Expand your investment profile and see how CPI can really change your life!
