Test My Ad in 20 seconds →Swayable has built a strong reputation for rigorous creative testing, particularly in political campaigns and brand advertising. Their methodology is genuinely sophisticated.
But rigorous doesn't always mean fast — and for many marketers, 24 hours is too long.
Swayable's platform runs randomized controlled trials (RCTs) — the same methodology used in medical trials. Respondents are randomly assigned to test groups (see your ad) or control groups (see a placebo). The difference in attitudes between groups measures your ad's "persuasion" impact.
This is a legitimate, statistically rigorous approach. Swayable has worked with brands like Airbnb, Amazon, Meta, Paramount, T-Mobile, and Uber. They've been particularly influential in political advertising, where Democrats have dramatically increased RCT testing in recent election cycles.
The tradeoff: Results take 24+ hours, require panel recruitment, and pricing requires a sales conversation.
TestMyAdvertising is trained on 18 trillion real-world outcomes — when two pieces of content competed for engagement in the real world, which one won? We learn from what actually worked in market, not opinions about what might work.
We then proved with Fortune 500 & Super Bowl advertisers that this beats all other approaches to predicting real-world outcomes, and were awarded a patent on it.
The tradeoff: We predict which ad wins, not why it persuades. Different questions, different use cases.

Swayable's RCT methodology is genuinely rigorous:
This isolates the causal effect of your creative on stated attitudes. It's the same methodology used in medical trials — which is why Swayable calls it the "gold standard."
The limitation: You're still measuring what people say after seeing your ad in a research environment. Stated attitude change doesn't always translate to real-world behavior.
TestMyAdvertising takes a fundamentally different approach:
We're trained on 18 trillion real-world outcomes — when two pieces of content competed for engagement in the real world, which one won? We learn from what actually worked in market, not opinions about what might work.
This captures revealed preference — what people actually did, not what they said they'd do. No survey environment. No artificial exposure. Just competitive outcomes at massive scale.
We then proved with Fortune 500 & Super Bowl advertisers that this approach beats other methods, and were awarded a patent on it.
Swayable delivers results in 24 hours — fast by traditional research standards. But in practice:
TestMyAdvertising delivers results in 20 seconds. That changes how you can use creative testing:
In the time Swayable completes one RCT, you could test 4,320 creative variations with TestMyAdvertising.

Different approaches to related questions. Swayable uses randomized controlled trials to measure persuasion — how your ad changes stated attitudes compared to a control group. TestMyAdvertising predicts which ad wins in market based on 18 trillion real-world competitive outcomes. Swayable measures attitude change through surveys; we predict competitive performance from revealed behavior. Swayable takes 24+ hours; TestMyAdvertising takes 20 seconds. Swayable requires sales contact; we start at $99.
We measure different things. Swayable's RCT methodology is statistically rigorous for measuring persuasion (stated attitude change). TestMyAdvertising is validated for predicting market performance — which ad wins when content competes in the real world. Our predictions have driven 3.6x acquisition improvement and 4.4x brand lift in controlled tests with statistical significance (p < 0.05). We were awarded a U.S. patent for proving our methodology beats other approaches.
Not directly. Swayable specifically measures attitude change through controlled exposure experiments. TestMyAdvertising predicts which creative performs better in market. If you specifically need to isolate persuasion impact on stated attitudes, Swayable's RCT methodology is designed for that. If you need to know which ad wins, we're faster and more accessible.
Swayable Express is their self-serve option for faster testing. It's a good step toward accessibility, but still requires 24+ hours for RCT results. TestMyAdvertising delivers in 20 seconds with no account required.
Yes — and some teams do. TestMyAdvertising for rapid screening of many concepts (which 5 of these 20 options should we pursue?), then Swayable for deep persuasion measurement on finalists. Different tools for different stages of the creative process.
No. TestMyAdvertising is pay-per-test starting at $99 with no account required. Swayable's full platform requires enterprise sales conversations; Swayable Express offers more accessibility but still requires account setup.
