Google Ads for Mobile Apps: App Campaign Setup, Tracking, and Scaling

Question 1

What Google Ads campaign type should I use to promote my mobile app?

Accepted Answer

The article states Google App Campaigns (formerly Universal App Campaigns) are the primary way to advertise a mobile app through Google Ads. According to groas, the format automatically combines text, image, video and HTML5 assets with app store listing data and distributes ads across Search, Google Play, YouTube, Gmail, Discover and Display Network apps and sites. Advertisers do not select keywords, choose placements or write individual ads for each network, but optimize toward installs, in-app actions or pre-registrations.

Question 2

Should I use Target CPI, Target CPA or Maximize Conversions for my app campaign?

Accepted Answer

The article describes Target CPI as setting a target price per install for early-stage volume, Target CPA as setting a target cost for a specific in-app event such as registration, purchase or subscription, and Maximize Conversions as spending the full budget without a target for learning-phase data collection. According to groas, Target CPA generally requires at least 10 conversions per day to become reliable and Maximize Conversions can produce volatile CPIs. The article recommends starting with Target CPI or Maximize Conversions to accumulate install data, then shifting to Target CPA once in-app event volume is sufficient.

Question 3

How much daily budget does an App Campaign need and how should I handle the learning phase?

Accepted Answer

The article states App Campaigns have a learning phase that typically lasts several days while performance fluctuates. According to groas, advertisers should set daily budget to at least 50 times target CPI, for example at least $100 per day if target CPI is $2. The article recommends not making significant changes to bids, budgets or assets during the learning phase because adjustments reset the learning process.

Question 4

What text, image and video assets do Google App Campaigns require?

Accepted Answer

The article lists up to five headlines (30 characters each) and five descriptions (90 characters each), up to 20 images prioritizing 1200x628, 1200x1200 and 480x800, and up to 20 videos in portrait (9:16), landscape (16:9) and square (1:1). According to groas, missing a format means missing inventory, and if advertisers do not upload video Google will auto-generate video from app store listing assets which almost always underperforms custom creative. The article states thin asset libraries are one of the most common reasons app campaigns underdeliver.

Question 5

How does iOS attribution with SKAdNetwork affect Google App Campaigns in 2026?

Accepted Answer

The article states iOS attribution remains constrained by Apple's privacy framework with SKAdNetwork providing aggregated, delayed data. According to groas, conversion data arrives 24 to 48 hours after the install, sometimes longer, with a restricted set of conversion value combinations and more limited remarketing because most users decline ATT opt-in. The article recommends investing proportionally more in Android campaigns where data is richer while running iOS campaigns with broader optimization targets and accepting wider performance variance.

Question 6

When should I increase budget versus adding a second App Campaign or expanding geos to scale?

Accepted Answer

The article states increasing daily budget by more than 20% at a time risks resetting the learning phase and destabilizing performance. According to groas, advertisers should add a second campaign targeting a different conversion event, geo or creative angle to preserve stability while expanding reach, and keep new geos in separate campaigns so their learning phase does not disrupt established campaigns. The article notes CPI benchmarks vary dramatically by country and mixing geos gives the algorithm conflicting signals.
