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
