Measuring the ROI of Creative Ad Campaigns

‍

A lot of clients go into marketing campaigns with a pure performance mindset. They have a set of KPIs that they use to measure the success of their creative. Nailing these is all that matters. 

This can lead to some foggy thinking, though. If you aren’t looking at a comprehensive range of KPIs, you could end up missing the mark. And a tunnel-vision approach can lead to sacrificing quality at the altar of metrics that might not even be giving you the full picture to begin with.

Obviously, there’s nothing wrong with prioritising growth. In fact, reports show that companies who put growth at the forefront of their strategies are more naturally inclined to embrace creativity. This means that, as a mindset, eschewing quality creative in pursuit of instant, measurable success can be counterproductive. 

If you’re focused on performance, you need to care about your creative. Instead of thinking of it as an indulgence, it should be viewed as the revenue magnet it is, especially when augmented by the appropriate use of value trackers. Fortunately, there are now more ways than ever to do just that.

Why measuring ROI matters more today

Creative can seem abstract, or at least hard to quantify in terms of performance. But in 2025, every part of the funnel is being scrutinised. 

High-quality creative content improves the metrics that matter:

• Lower CPAs.
• Higher ROAS.
• Stronger retention.
• Lower churn.

Better creative leads to better business outcomes. Simple as that.

Beyond Impressions: key metrics that reveal your creative's true impact

Measuring impressions is a handy finger-in-the-wind measure of how your creative’s performing. But alone, it can measure as much engagement as counting flyers handed out in the street. What performance clients need is evidence of outcomes:

• Click-through rate (CTR): Is the creative making people act?
• Cost per acquisition (CPA): Is the creative making each customer cheaper to convert?
• Return on ad spend (ROAS): Is the creative contributing to profit?
• View-through conversions: Is your creative doing its job, even when it doesn’t get the click?

These are the numbers worth tracking, and they all respond to quality creative.

Finding the right fit for your campaign

If you’re going to invest in creative, make sure the attribution model doesn’t hide the truth about where your creative is paying off.

Popular models include:

• Last-click: This gives all the credit to the very last ad someone clicked before buying. It’s easy to set up and understand, but it often misses the bigger picture, e.g., disregarding the video that got someone interested in the first place.
• First-click: This model credits the first ad someone interacted with. It’s useful for spotting which creatives pull people in. But it ignores what actually sealed the deal.
• Linear: This spreads credit evenly across every touchpoint. It’s fair, in theory, but in practice it treats every piece of creative as equally important, which usually isn’t the case.
• Time decay: Gives more credit to ads that were seen closer to the moment of conversion. It’s great if you’re running time-sensitive offers or want to understand what helped tip people over the edge.
• Data-driven attribution: This one uses machine learning to figure out which creatives actually made a difference. It looks at patterns across your campaigns and assigns credit based on real influence rather than assumptions. For the last few years, analysts have largely moved away from the other models and concentrated on data-driven attribution to make sense of their conversions.

Smart attribution tells you what’s working about your creative. Once you know that, you can only make it better.

A/B testing creative elements: A scientific approach to optimization

You don’t have to gamble on one idea. Use A/B testing to run controlled experiments and continuously optimize. Modern platforms let you test faster and in more detail than ever:

Test variables like:

• Hooks in the first 3 seconds
• Visual formats (illustration vs. live-action)
• Voiceover tone
• CTA wording and placement
• Text overlay styles

Brands who consistently test creative elements report improvement in ROAS over those who don’t.

Even quality creative doesn’t just come out oven-ready. It has to be refined, like any performance lever.

The Long-Term Value of Brand-Building Creatives vs. Performance Ads

Creative doesn’t have to be short-term or long-term. It can do both. You can run a conversion campaign today and build brand value tomorrow. Performance ads are still your bread and butter, but they perform better when backed by strong brand-building content.

What to track over time:

• Reduced CPA as trust builds
• Higher LTV
• Lift in branded search
• Better retention from better first impressions

TikTok, YouTube, and Meta now offer brand lift and recall tools. Use them. The results will back your creative investments.
