What an MMP does not do

The one job an MMP has

A mobile measurement partner sits between your app and the ad platforms. It records a click on a tracking link, sees the install or the purchase that follows, and decides which ad gets the credit. It then reports that decision to you and sends it back to the ad platform as a postback. Everything else on a vendor's feature page is built around that match.

Because the job is narrow, teams often expect more from it than it gives. The five gaps below come up most often when a small team buys its first MMP.

Five things it leaves to you or to another tool

1. It does not buy or optimise media

Budgets, bids and creatives stay inside the ad platforms. Some MMPs can build audiences and sync them to those platforms, but the buying still happens there. The MMP changes what those platforms learn from, because it tells them which installs turned into paying users. It does not move a dollar of spend on its own.

2. It does not explain behaviour inside the product

An MMP can tell you that users from one campaign bought more than users from another. It cannot tell you which screen made them leave. That question belongs to a product analytics tool, and many teams run both: the MMP for where users came from, analytics for what they did.

3. It does not message your users

Push notifications, email and in-app messages are sent by an engagement platform. The MMP's part is the link inside the message. A deep link opens the right screen, and the MMP counts the open as a re-engagement.

4. It does not replace your own data store

Dashboards show aggregated reports. If you want every click and event as rows in your own warehouse, you need raw data export, and that is often tied to a higher plan. Check which plan includes it before you assume the data is yours to move.

5. It does not fix the campaign

Measurement shows that an ad is losing money. It cannot make the ad better. A team that installs an MMP and changes nothing about its creatives or its offer will see the same results, now with a clearer label on them.

Where the boundary is less clear

Two jobs are commonly sold with attribution. The first is deep linking, covered in why deep linking and attribution are bought together. The second is fraud prevention, covered in ad fraud prevention basics. Whether either one is included in the plan you are looking at varies by vendor, so read the plan page and do not rely on the product page.

How to use this list

Write down the question you want answered before you compare vendors. If the question is which channel to spend more on, an MMP is the right tool. If the question is why users drop off after signup, or how to bring lapsed users back, start with the tool built for that and add attribution when you begin to pay for traffic. The guide on whether you need an MMP walks through that decision.
