Why you shouldn’t be scared of paid user acquisition

If you’ve spent time in game dev communities, you’ve probably seen some uncertainty around paid user acquisition. We understand why. If you’re an indie developer or you’re running a small studio, spending money to buy installs can sound like a risky move, and you may be concerned about getting a negative reputation from mobile ads.

However, when done strategically and measured properly,  paid user acquisition is one of the most effective growth levers for apps and games.

In this article, we’ll break down what paid user acquisition is, why it’s nothing to fear, and how you can use it to grow your game sustainably.

‍What is paid user acquisition?

At its simplest, paid user acquisition means investing money to get new users for your app or game. Instead of waiting for players to find you organically through word of mouth referrals, social media, or online communities, you can give your game a boost with targeted paid acquisition campaigns that put your titles in front of users most likely to be interested.

Think of it as the difference between opening a new shop in the city center and hoping passersby notice it, versus orchestrating a grand opening with flyers, social media ads, ribbon-cutting ceremony, and even local influencers to make sure people actually show up.

In mobile marketing terms, this means paying for installs or app interactions through channels like social ads, app store ads, offerwalls, or influencer sponsorships.

The key point is that you need to think of paid UA as an investment. When measured properly, it can bring in high-value players, generate positive  return on ad spend (ROAS), and unlock growth that organic strategies simply can’t match. In other words, paid user acquisition is less about “buying downloads” and more about accelerating your game’s path to visibility and profitability.

3 reasons why developers fear paid UA (and why they shouldn’t)

While paid user acquisition is such a powerful growth lever, there are still developers who hesitate to invest, and this is mainly due to  common misconceptions. 

Here are the most frequent reasons we hear around mobile app developers being hesitant to adopt paid user acquisition strategies: 

‍

“It’s too expensive”

Many indie developers assume you need a six-figure budget to even start. Though it’s true that big companies invest heavily in paid user acquisition, in reality, you can launch small test campaigns with just a few hundred dollars to see what works before investing more money. Plus, the goal of paid UA is to generate ROAS – which means if you find the right channel with the right users, you’ll be earning back more money than you’re spending on your campaigns. 

‍

“It only works for big companies”

It’s true that giants like Supercell or Scopely spend millions, but that doesn’t mean smaller studios can’t compete. With smart targeting, creative ad formats, and a clear KPI framework, even a smaller budget can bring high-quality users.

“There’s no way to know if it’s working”

This one might have been true years ago, but today, paid user acquisition is one of the most trackable strategies out there. You can measure every install, track retention, and calculate your return down to the decimal. That means that when you launch campaigns, you’ll have the detailed data you need to understand what channels, creative, messaging, and more is working (and which is not) so you can optimize for ROI. 

Paid user acquisition campaigns explained

Now let’s take a look at what paid acquisition campaigns actually include. Like many things in mobile app marketing, there’s no one-size-fits-all approach, and you can (and should!) design campaigns around your budget, goals, app type, unique brand identity, and the type of players you want to reach. However, there are some consistencies across the mobile UA landscape to keep in mind when planning your paid acquisition strategies. 

Here are the most common paid UA channels: for mobile

• Social ads: Facebook, Instagram and TikTok, remain powerful for targeting specific audiences with engaging creatives.
• Ad networks: Programmatic networks give you scale and automated optimization.
• Search ads: Apple Search Ads or Google App Campaigns  put your app in front of people already looking for something similar.
• Offerwalls: Reward-based ads where users opt in to try your app in exchange for in-game rewards. This format is especially effective for driving engaged players.
• Influencer marketing: Collaborating with creators who can authentically showcase your game to their communities.
• CTV: Connected TV ads are those that play on any TV or device that streams digital video, like the interstitial ads you might get on Netflix or Roku. 

But it’s not only about where you run paid acquisition campaigns, but also how you set them up:

• Targeting options like regions, interests, and lookalike audiences help you reach players most likely to stick.
• Creative optimization means testing multiple versions of ad visuals and copy to see which message resonates best.
• Iteration and testing are crucial: launch small, analyze the data, then double down on what’s working.

A good paid user acquisition campaign is part art, part science: you combine creativity with data-driven decisions, making sure every dollar spent moves you closer to sustainable growth.

‍ASO vs paid user acquisition

One thing that keeps developers from investing in paid user acquisition is thinking that app store optimization (ASO) is often enough. 

Though this has been true in some cases, paid UA has now become essential. You can think of ASO as setting the stage, and paid UA as turning on the spotlight. The answer isn’t one or the other, but both:

• ASO is the foundation: A well-optimized app store page helps you get discovered, improves conversion rates, and builds a steady flow of organic installs.
• Paid UA is the fuel: It accelerates visibility and ensures you’re not waiting months for organic growth to kick in. Paid campaigns can push your app into the charts, which in turn strengthens your organic traffic. It’s a win-win loop.

Key metrics & KPIs to track for UA

Here’s the part that turns paid user acquisition from “scary expense” into “predictable growth engine.” In fact, the most successful campaigns track a set of clear metrics that show whether the money spent is paying off.

The key ones are:

• CPI (Cost Per Install): how much you spend to acquire a single user. A low CPI looks nice, but it only matters if those users keep playing over time.
• ROAS (Return on Ad Spend): usually tracked at D7, D30, and D90 to see when your investment breaks even or turns profitable.
• LTV (Lifetime Value): how much a user is worth to you over time. If LTV is higher than CPI, you’re on the right track.
• Retention rates: users who come back on D1, D7, or D30. High retention means your UA campaigns are bringing in quality players.
• Incremental revenue: the extra money your app makes thanks to UA, beyond what you’d earn from organic installs alone.

By monitoring these KPIs closely, you know exactly when to keep investing, when to adjust, and when to stop underperforming campaigns.

Of course, tracking all this data can feel overwhelming at first. So, relying on a Mobile Measurement Partner (MMP) can help you here. MMPs are designed to help app developers measure campaign performance across multiple channels. They act as a single source of truth: they attribute installs to the right campaigns, prevent double-counting, and give you the full picture of your UA ROI.

And this is where the fear around paid UA usually fades: once developers see the results tied directly to the spend, it stops feeling like “throwing money away” and starts feeling like an investment they control.

Conclusion

Paid user acquisition doesn’t need to be intimidating. By defining clear KPIs, starting with manageable budgets, and combining your campaigns with strong ASO, you can build a steady pipeline of high-value users.

The key is to treat paid UA as an investment in your app’s future. So if you’ve been holding back, start small. Test one channel, track the results, and let the data guide your next step. Because once you see the numbers working in your favor, you’ll realize: there’s nothing to be scared of.
