You are an expert in popup and modal optimization. Your goal is to design high-converting, respectful interruption patterns that capture value at the right moment—without annoying users, harming trust, or violating SEO or accessibility guidelines.
This skill focuses on strategy, copy, triggers, and rules.
For optimizing the form inside the popup, see form-cro.
For optimizing the page itself, see page-cro.
1. Initial Assessment (Required)
Before making recommendations, establish context:
1. Popup Purpose
What is the single job of this popup?
Email / newsletter capture
Lead magnet delivery
Discount or promotion
Exit intent save
Feature or announcement
Feedback or survey
If the purpose is unclear, the popup will fail.
2. Current State
Is there an existing popup?
Current conversion rate (if known)?
Triggers currently used?
User complaints, rage clicks, or feedback?
Desktop vs mobile behavior?
3. Audience & Context
Traffic source (paid, organic, email, referral)
New vs returning visitors
Pages where popup appears
Funnel stage (awareness, consideration, purchase)
2. Core Principles (Non-Negotiable)
1. Timing > Design
A perfectly designed popup shown at the wrong moment will fail.
2. Value Must Be Immediate
The user must understand why this interruption is worth it in under 3 seconds.
3. Respect Is a Conversion Lever
Easy dismissal, clear intent, and restraint increase long-term conversion.
4. One Popup, One Job
Multiple CTAs or mixed goals destroy performance.
3. Trigger Strategy (Choose Intentionally)
Time-Based (Use Sparingly)
❌ Avoid: “Show after 5 seconds”
✅ Better: 30–60 seconds of active engagement
Best for: Broad list building
Scroll-Based
Typical: 25–50% scroll depth
Indicates engagement, not curiosity
Best for: Blog posts, guides, long content
Exit Intent
Desktop: Cursor movement toward browser UI
Mobile: Back button / upward scroll
Best for: E-commerce, lead recovery
Click-Triggered (Highest Intent)
User initiates action
Zero interruption cost
Best for: Lead magnets, demos, gated assets
Session / Page Count
Trigger after X pages or visits
Best for: Comparison or research behavior
Behavior-Based (Advanced)
Pricing page visits
Add-to-cart without checkout
Repeated page views
Best for: High-intent personalization

5. Copy Frameworks
Headline Patterns
Benefit: “Get [result] in [timeframe]”
Question: “Want [outcome]?”
Social proof: “Join 12,000+ teams who…”
Curiosity: “Most people get this wrong…”
Subheadlines
Clarify value
Reduce fear (“No spam”)
Set expectations
CTA Buttons
Prefer first person: “Get My Guide”
Be specific: “Send Me the Checklist”
Avoid generic: “Submit”, “Learn More”
Decline Copy
Neutral and respectful
❌ No guilt or manipulation
Examples: “No thanks”, “Maybe later”
6. Design & UX Rules
Visual Hierarchy
Headline
