In today’s digital-first world, mobile apps are everywhere: entertainment, shopping, education, payments, and more. Behind every successful app, however, there is a smart backend system which collects and tracks performance, user activity, and marketing effectiveness. This is where a Mobile Measurement Partner (MMP) comes in.

If you’ve ever wondered if it’s with the ad campaigns that app developers know which campaign gives them the most users or how they decide which feature to improve next, the answer is often with a MMP mobile measurement partner.

What Is an MMP Mobile Measurement Partner?

A mobile measurement partner (MMP) is a third-party service or tool to assist mobile app developers and marketers to see where their users are from, and what behavior they are exhibiting in their mobile app. Specifically, it ties together all the channels of advertising, such as Google Ads, Facebook, and Instagram ads, influencer campaigns, to determine which of these is performing best.

Whenever a user clicks on an ad and downloads an app, MMP mobile measurement partners will track the entire user journey, starting from the first click all the way up to in-app purchases and usage, so that a business can make more informed marketing decisions, improve their user onboarding experience, and minimize unnecessary ad spend.

Why Are MMPs Important?

Without proper tracking, mobile marketers are throwing darts in the dark. With the growth of mobile users in India (with over 1.2 billion mobile subscribers) and more than 80% of internet traffic coming thru mobile devices, accurate tracking isn’t just nice to have, it’s a need to have.

A mobile measurement partner (MMP) helps mobile applications to:

  • Track installs and user sources
  • Understand what users do after installation
  • Identifying fraud and fake installs
  • Measure Return on Investment (ROI)
  • Optimize marketing budgets

In actual fact, apps that use a mobile measurement partner (MMP) get significantly better performance out of their ads. With accurate data, business owners can focus on channels that generate real business results.

Key Functions of an MMP Mobile Measurement Partner

1. Attribution Tracking

This is the primary purpose of any MMP for mobile apps. Attribution is the process of determining which ad or campaign resulted in a particular user action. For example, if a user sees a Facebook ad, clicks on the ad, and installs the app, the MMP mobile measurement partner would attribute that install to Facebook.

2. In-App Event Tracking

Once the user has installed the app, we need to know what they do thereafter–do they sign up? do they watch a video? do they make a purchase? App measurement partner tools track in-app events and help businesses understand their app experience.

3. Campaign Optimization

One benefit of working with an MMP mobile measurement partner is they show you which ads are bringing in the highest-value users to discover which ads are worth optimizing. Instead of spending money willy-nilly, marketers can invest in the best-performing channels and improve their return on ad spend (ROAS).

4. Fraud Detection

Ad fraud is a real issue. Fake installs, click spamming, and bots can cause wasted dollars and extra headaches. The best mobile app tracking partners have built-in fraud detection tools that can filter out invalid activity.

5. Real-Time Data

Timely decisions require timely data. An MMP mobile measurement partner provides real-time dashboards, so businesses are always looking at the freshest data.

How Does an MMP Work?

The process begins when a user clicks an advertisement or sees an advertisement. The MMP mobile measurement partner collects this information and assigns the user a unique identifier. After a user downloads and opens an app, the MMP associates the install with the original source.

From this point, MMP tracks what the user does inside the app, whether that is signing up, purchasing, or completing a level in a game, before returning the information to the marketing team in detailed reports.

The tracking described above lets marketers see everything about their advertising performance and user behavior with one system, the MMP mobile measurement partner.

Who Should Use an MMP?
