• See our best practices for what’s working right now with Google App campaigns, SKAN Discrepancies, Modeling Delays (pre/post iOS 14.5) and Firebase Events.
  • According to Google, bidding on Firebase (FiB events) resulted in a median +13% increase in installs and a +20% increase in in-app events with no significant change to cost per conversion.
  • Advertisers benefit by understanding sources of discrepancies between SKAN data and Google Ads reporting, which may include views, web-to-app, cross-network attribution, attribution windows, and reinstalls.
  • For iOS campaigns, advertisers should expect at least a 5-day lag in-app campaign modeled conversions and should avoid assessing performance in the first two weeks or before the campaign has generated at least 100 conversions (purchases, events, installs, etc.).

How To Optimize Google App UA Right Now

As mobile app advertisers adjust to an evolving ad ecosystem with the loss of IDFA and increasingly automated media buying across networks, Consumer Acquisition brings you the most up-to-date recommendations for Google App UA Campaigns. As a Google App Preferred Creative Partner Agency, we have market insights and creative expertise from managing over $3 billion in creative and social ad spend for the world’s largest mobile apps and web-based performance advertisers.

Here’s how to better understand, measure, and optimize your Google App UA campaigns right now.


Bidding on Firebase (FiB) events increases performance

App campaigns bidding on FiB events performed better than app campaigns bidding on non-FiB events. Google reports that the median campaign that switched to using Google Analytics for Firebase conversions for bidding saw a +13% increase in installs and a +20% increase in in-app events with no significant change to cost per conversion.

Understanding Google Ads Reporting vs. SKAN 

Adjust and Appsflyer dashboards now show Google SKAN data. Below are the sources for common discrepancies between SKAN data and Google Ads reporting, including views, web-to-app, cross-network attribution, attribution windows, and reinstalls.


Google Ads Reporting vs. SKAN

What’s working for us right now on Google: 

  • Strongest performance from English language targeting Germany, UK, France, Canada & Netherlands
  • French and German language campaigns targeting tier 1 countries in Europe show promise
  • The key performance lever is the bid, adjusted periodically based on 7D ROAS
  • Targeting only Android devices; iOS campaigns, when tested in Q1, had low yields

Best Practices For Optimizing Google App Campaigns


  • Use a target CPA (tCPA). If you haven’t tested this bidding strategy yet, start now. We’ve found it to be a very efficient use of ad budget.
  • Use a target return on ad spend (tROAS). This feature isn’t out just yet, but it will be available in June for App Campaigns on iOS and Android. Once it’s live, you’ll be able to, say, specify that you want Google to find users who will spend three times what it cost you to acquire them. What advertiser wouldn’t want to do that?


  • Set your daily budget caps at least 50X target of CPI or 10X of target CPA.
  • Don’t change target CPI/CPA bids by more than 20% in 24 hours until your campaign is generating 20-30 targeted in-app events per day.
  • Target CPI campaigns’ bids should start at least $4-5, even if your CPI goal is lower.
  • Target CPA campaigns’ bids should start at least 20-30% higher than the goal.
  • Don’t wait until your app has launched to start building your user base: Pre-launch campaigns are available, and they work.


  • Be generous with creative assets. Google App Campaigns work best with a variety of creative – both creative formats and messaging approaches. The algorithm will figure out how to mix and match your images, text, and videos… but you’ve got to give it enough assets to find the ideal combination.
  • Always include video creative. We’ve found that if a campaign hasn’t been using videos, adding just two videos to their creative asset mix can increase the campaign’s conversions by 25%. So yes, maybe videos are a bit more expensive. Maybe they do take a bit longer to create. But they punch above their weight when it comes to ROAS. And besides – if you don’t want to make videos, we can do it for you.
  • When you get your videos made, make sure they can “flex,” as in that they can appear in different views and devices, and still look good.
  • Think beyond user acquisition. We’re seeing some really nice returns with retention campaigns. If you do it right, it absolutely pays to advertise to all those people who downloaded your app but then either didn’t use it or never bought from it. They’ve already done the hard part of installing the app – often they just need a little nudge to activate or to make their first purchase.
