CPI

CPI (Cost Per Install) is a payment model in affiliate marketing where the advertiser pays only for the actual app installation. This scheme works well when promoting games, related services, and other app offers.

CPI is a key metric in mobile traffic. The webmaster receives a fixed payment for each install, which a tracker or SDK registers. The model attracts users quickly during the launch of new apps or promotional campaigns, enabling rapid campaign scaling.

How is compensation calculated in the CPI model?

It starts with a user clicking on an ad. Then, the system redirects the user to the App Store or Google Play. To get an install in an affiliate meaning, the app must be installed and launched. A tracking system (AppsFlyer, Adjust, Branch, and others) records the fact of the action and sends a postback to the affiliate network. The affiliate will receive a reward only if all offer conditions are met. Usually, it's just installation and launch. Yet, sometimes GEO, device type, and OS are also crucial. The verification works in real time, too.

Where is the Cost Per Install model used?

CPI is in high demand in the gaming (arcade projects, slots, strategy games) niche. Most often it's gambling and betting, as push traffic is highly effective there, thanks to a motivated audience. The financial sector also benefits from CPI. It helps the affiliates to promote banking apps, payment systems, and credit services.

CPI is suitable for promoting utility apps and VPN solutions, where the main goal is to maximize installs rather than encourage further activity. In legal apps, CPI is often used as a tool to quickly boost the number of downloads and improve rankings in app stores.

How to achieve higher CR in CPI offers?

It's best to tailor the creatives to the specific GEO and platform (iOS or Android). Warm up users with pre-landing pages that clearly explain why they should install the app. Calls to action should use the most straightforward phrases like "Download for free" or "Open now."

In addition, optimizing target events within the app can help secure bonuses for user retention. It's important to closely track conversion throughout the entire funnel to identify and fix weak points. The higher the engagement and relevance, the more stable the conversion.
