AI CTA Roaster
Get honest, AI-powered feedback on your Call to Action. We audit your microcopy, urgency, and design to see if your buttons actually convert or just take up space.
The Psychology of the Click
Heurilens’ AI CTA Roaster is designed to perform a brutal but necessary audit of your conversion points. It scans for Call to Action (CTA) elements to evaluate their linguistic intent, visual prominence, and psychological pull. It detects issues such as passive microcopy, insufficient visual contrast, missing urgency signals, and poor spatial relationship with the primary value proposition.
A Call to Action is the climax of the user's journey. It is where cognitive interest transforms into measurable business value. When a CTA is visually weak or linguistically vague (e.g., 'Submit', 'Learn More'), the user's brain defaults to inaction. Our AI analyzes these elements through the lens of Loss Aversion, Reward Anticipation, and Decision Fatigue, ensuring your buttons do more than just exist — they persuade.
This roaster doesn't just check for 'best practices'; it measures the emotional resonance of your interface. It evaluates the 'Commitment Cost' of your labels against the 'Perceived Value' of your offer. Because in high-performance UX, every word on a button is an investment in user trust. If your CTA doesn't promise a transformation, it's just a rectangle with text.
High-Intent Microcopy
We audit your button text for 'Active Value' verbs. Ensuring that your labels focus on the user's gain rather than the effort they must expend.
Visual Saliency Audit
Using attention heuristics, we verify if your CTA stands out in the visual field. If it doesn't pass the 'Squint Test', it doesn't convert.
Masterclass: The Fogg Behavior Model for Buttons
Effective CTAs exist at the intersection of Motivation and Ability. Our AI uses the following conversion framework:
- The Spark (Trigger): A CTA is a trigger. It must be timed exactly when the user's motivation is at its peak (immediately after a value prop).
- The Path (Ability): We evaluate how easy it is to act. High friction (long forms, confusing labels) kills even the most motivated users.
- Micro-Urgency: Adding 'Today', 'Now', or 'Instant' increases the likelihood of an immediate click by reducing the 'Think-it-over' window.
Common Questions
What color should my CTA button be?
There is no 'magic' color. The best CTA color is the one that has the highest contrast relative to your brand palette. It should be the 'Action' color used nowhere else.
How many CTAs should I have on one page?
Ideally, one primary CTA per viewport. Multiple competing actions cause 'Decision Paralysis', where the user ends up choosing nothing at all.
Is 'Click Here' still effective?
Never. 'Click Here' describes a physical action, not a result. Use 'Get Started', 'Join Now', or 'Save My Spot' to focus on the outcome.
Does the size of the button matter for conversion?
Yes, to an extent. It needs to be large enough to be easily hit (min 48px), but making it 'huge' can often trigger defensive responses in users who feel they are being pushed too hard.
