Popup CRO
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
