Gamelight Growth Guides | Creative Optimization

In user acquisition, creativity is key. Budgets, bids, and targeting matter, but the single biggest factor that can make or break performance is your ad creative. The right video or playable can double your click-through rate, decrease your CPI, and make the difference between a campaign that scales and one that dies in testing.

This installment of Gamelight’s Growth Guides breaks down how to approach creative optimization with structure, not guesswork:

Why Creative Testing Matters

No amount of targeting or bidding strategy can save a bad creative. However, this also means a winning ad can outperform everything else by driving higher engagement and installs.

Good creative does three things:

Communicates value clearly and quickly
Grabs attention in the first seconds
Drives action with a strong CTA

I believe creative is the most essential way to introduce a game and communicate its core message to users. While campaign optimization focuses on metrics such as ROAS, CPI, and LTV and determines who to target and how efficiently to deliver impressions, creative focuses on how effectively we communicate the game’s unique value and appeal. As media algorithms become increasingly automated, creative has become the most powerful and differentiating lever for growth. A single well-crafted creative that captures attention and achieves a low CPI can significantly boost overall campaign performance. When CPI decreases, ROAS naturally improves, providing a strong foundation for scaling campaigns. In my experience working with hyper-casual games, I have seen campaign volumes triple purely through creative optimization. The same trend continued even in IAP-driven mid-core and hardcore titles. A lower CPI allows us to reach more users, expand the target audience, and accelerate UA growth. By refining creative messaging, we can also attract players from other genres beyond our core audience. Ultimately, I see creative optimization not just as a way to improve ad efficiency but as a core driver of scalability and sustainable UA growth.

Strong creative doesn’t just drive installs; it defines how your game or app is perceived. As Kyuyoung Kim, Global UA Manager at 111퍼센트, explains:

Creative Testing: The Right Way

Testing isn’t about producing dozens of random ads, but about learning systematically.

Start with a hypothesis
For example:
Would showing gameplay in the first 3 seconds lift CTR vs. character art?
Does adding a reward mechanic improve install rates?

Test small, then scale

Run low-budget tests to validate concepts.
Don’t decide after just a few hundred impressions; give algorithms time to learn.

At this stage, what matters most is clarity: knowing exactly what you’re testing and why. A well-defined creative hypothesis makes the difference between useful insights and wasted spend.

As Nehir Usta, Co-Founder at PlayableX, puts it:

Creative Optimization strategies are becoming a crucial point to drive UA spend more profitably, because of the first interaction of audiences and related engagements under the CTR, CPC, IPM and CPI metrics.

I recommend running creative tests with at least a $50 daily budget for a minimum of three days to gather statistically meaningful data. Rather than testing across multiple platforms at once, it’s more effective to focus on a single platform and build consistent testing data there. If playable creatives are available, I usually recommend testing on Unity, while for video creatives, Facebook tends to be the most efficient platform. To use the testing budget as efficiently as possible, a well-structured testing setup is essential. You need to clearly define what variable you want to test and how many variations you will include within that element. A good starting point is to include the game’s USP but test it through different creative concepts and formats that highlight distinct angles. By running concept-level tests like this, it becomes much easier to identify which concept and format perform best, and you can establish a faster and more data-driven iteration process moving forward.

Kyuyoung Kim points out:

Not all channels behave the same, and knowing each platform’s creative strengths helps maximize testing results.

Meta Ads → Fast feedback, great for A/B testing concepts.
Google App Campaigns → Broad reach but less control; feed it your best performers.

Isolate variables

Change one thing at a time (hook, CTA, color scheme, format).
If you change too much, you won’t know what drove the difference.

To get the most out of your testing budget, structure and focus are everything.

Platforms: Where to Test

Each platform has its own creative logic. As Nehir Usta explains:

The creative strategy should align with each platform’s strengths: TikTok favors fast, authentic, UGC-style videos; Meta rewards variation and iterative testing; Google benefits from broad concept diversity and automated asset optimization. Videos and statics are still powerful tools for reach and storytelling, but playable ads bring an extra layer of interactivity that many networks, like AppLovin, value highly. They don’t just show the game, they let players feel it, and that richer engagement data helps both the platform’s algorithms and the creative strategy to perform better. That’s why we see playables not as a replacement but as a priority format to maximize impact alongside video and static ads.

Modern UA is getting incredibly standardized, driven by algorithms and AI. Your creatives have to be one of the biggest growth drivers of your UA campaigns: it’s where data meets emotion, where you'll have the freedom to test as many angles as your imagination allows to convince your audience that your product is the one for them.

To close, Julien Daver, User Acquisition Team Lead at SplitMetrics, captures why creativity remains the human edge in a world of automated campaigns:

Ad Iteration Strategy

The real secret to creative optimization is iteration. Winning ads eventually fatigue, so you need a pipeline.

Step 1: Identify winners
Use CTR and IPM (installs per mille) as early signals.
Confirm performance with CPI and ROAS.

Step 2: Build variations
Keep the winning concept, but change elements, like the headline,
music, CTA or characters.
Build on what works instead of redoing everything.

Step 3: Refresh regularly
Rotate in new variations every 1–2 weeks to stay ahead of fatigue. 

Archive underperformers but keep learnings documented.

Step 4: Systematize
Treat creative like a production line:

Start with a clear question
Test one variable at a time
Validate before scaling

CTR & IPM → early signals
CPI & ROAS → confirm winners Watch fatigue indicators

Scaling on little data
Testing too many variables
Ignoring cross-platform adaptation

Align ads with store assets
Rotate creatives across platforms
Localize for key geos

Identify winners
Build variations
(CTA, music, visuals)
Refresh every 1–2 weeks

Meta → A/B concepts
Google → Broad reach

To wrap up, Günay Azer, founder of Gamelight, points out:

Creative is often treated as an asset, but it should be treated as a system: constantly tested, iterated, and improved. What works today will eventually stop working, and that’s normal. The teams that succeed in UA are the ones that treat creativity as a continuous process of testing, learning, and evolving their message as their audience changes.

Final Thoughts

Creative optimization is an ongoing process. The ads that work today will burn out tomorrow, but with a structured approach to testing and iteration, you’ll always have the next winner ready.

If UA is the machine, creative is the fuel, and the teams that treat creative testing as a system, not an afterthought, are the ones that scale the fastest.
