Testing into Certainty

Marketing science has a reputation for being complicated. Between endless data points, theories, and opinions, it can feel like guesswork rather than strategy. Marketers may be advised to trust assumptions, rely on single audience definitions, or believe that one creative will carry the weight of an entire campaign, but that is not how we work at Agility.

Our philosophy is simple. Marketing should be approachable and rooted in testing, learning, and proving what actually works. That’s what we mean by Testing into Certainty.

How We Test into Certainty

Persona-First Advertising

A persona is more than a demographic label or a loose audience segment. It’s a detailed profile that reflects how real people think, act, and make decisions. At Agility, we use identity resolution to create these personas with precision, combining signals such as behaviors, preferences, and patterns across multiple channels. The result is a set of targeted personas that ARE your actual buyers.

But we don’t stop at identifying them. Advertising success comes from managing the right mix of personas for each brand. Some personas may deliver strong immediate results, while others may build long-term brand equity. Our platform allows us to test which combinations perform best and then continuously rebalance that mix as your market shifts. This means your campaigns are always aligned with the reality of who is driving growth for your brand, not just an assumed audience.

Creative Variation

A single creative ad, no matter how strong, cannot carry the full weight of a campaign, especially as your targeting becomes more specific. Buyers respond differently depending on who they are, where they are, and what matters to them in that moment. That is why Agility takes a test-and-learn approach to creative.

We develop and run multiple creative variants simultaneously, each designed to appeal to different personas or spark distinct emotional triggers. Real engagement data tells us which creative is working, which needs to evolve, and how different personas react at different points in their buying journey. Studies in 2025 show that creative quality is the single most significant multiplier for media ROI, driving a return of up to 12 times when ads are optimized for effectiveness. Recent research also demonstrates that ads with strong creative effectiveness yield a 30% greater ROI, reinforcing your strategy of testing and iterating multiple variants for different target audiences. Instead of campaigns growing stale, they grow smarter over time, delivering messaging that stays relevant, persuasive, and effective.

Merged Channels

Buyers don’t live in a single channel. They stream music on their commute, scroll through mobile apps at lunch, and watch connected TV shows at night. If advertising only speaks to them in one of those places, the brand is quickly forgotten.

Agility merges channels into one coordinated system. Current marketing analyses reveal that only 8% of consumers complete purchases in a single channel, while integrated cross-channel campaigns result in a 37% increase in retention and 23% higher revenue. With Agility, display, CTV, native, audio, and more are all seamlessly integrated, allowing your brand to follow buyers naturally across their daily media journey. This approach expands reach by introducing your brand in underutilized spaces while also re-engaging existing buyers in new contexts. When channels reinforce each other, the message carries more weight, builds stronger mental availability, and creates lasting impressions.

Right Message, Right Time, Right Moment

Relevance is not just about what you say. It’s also about when you say it. The same message that inspires action in one moment can be ignored in another. That is why Agility uses data to find the windows of opportunity when buyers are most open to influence.

By combining persona insights with media behavior and timing signals, we deliver ads that land when they matter most. The result is less wasted spend, stronger emotional impact, and a brand presence that sticks. This approach improves your brand’s mental stickiness, keeping your brand top of mind long enough to influence the next purchase decision.

Visible Impact on Marginal ROI

Ultimately, advertising must prove its value. For Agility, testing into certainty means connecting every campaign back to measurable outcomes. We track incremental improvements in brand awareness and mental availability, and demonstrate how these gains translate into long-term returns on investment.

Instead of vague reports or abstract metrics, we provide clarity on what works, why it works, and where to focus efforts. The visible impact on marginal ROI is what gives marketers the confidence to know their investment is paying off, not just in the short term but in sustainable brand growth.

Why This Matters to Me

In college, I avoided courses where the answers were subjective. I wanted clarity, a right or wrong I could learn from. Years later, I found myself in advertising, a field where certainty is elusive. What I value most about Agility is how we’re building a platform designed to cut through that uncertainty. We test, measure, and refine until the impact is proven.

The direction of the industry itself also energizes me. We have more resources than ever to understand personas, measure results, and improve strategy. We have reached a turning point, a new era where marketing science can transition from theory to precision.

At the same time, the landscape has never been more competitive. There’s more advertising real estate than at any other point in history, which creates both unprecedented opportunity and unprecedented noise. In this environment, every initiative must be more calculated, more precise, and more deliberate than before.

That’s why I believe so strongly in testing into certainty. It transforms the uncertainty of brand advertising into something approachable and actionable. It gives marketers confidence in their decisions. And it ensures that, in this new era of advertising, brands are not only visible but also positioned to grow.
