popup-cro is a conversion optimization skill that designs website popup triggers, timing, and offers for developers who need lead capture flows that respect UX and dismissal preferences.

About

popup-cro is a reference skill for developers who run marketing sites, landing pages, or content funnels and need popups that convert instead of annoy. It frames conversion work around three non-negotiables: show offers when intent is real, make the benefit obvious in one glance, and never trap users—easy dismiss and remembered preferences matter as much as the headline. The reference walks six trigger families from crude time delays through scroll depth, exit intent, user-initiated clicks, multi-page journeys, and high-intent behaviors like cart or pricing revisits, with practical defaults such as 25–50% scroll and 30–60 second engagement windows rather than instant interruption. Use it while planning or refactoring modals on validate landing experiments, launch distribution pages, or grow lifecycle capture flows so agents and humans share the same CRO vocabulary before touching HTML, scripts, or A/B tools.

  • Three core CRO principles: timing, obvious value, and respectful dismiss UX
  • Six trigger strategies—time, scroll (25–50% depth), exit intent, click, page-count/session, and behavior-based segments
  • Timing guidance: avoid 5-second blasts; favor 30–60 seconds or engagement-based triggers
  • Popup-type patterns including email capture with page-context relevance
  • Mobile-aware notes (e.g., exit-intent alternatives: back button or scroll-up)

How do you design high-converting website popups?

Design and tune website popups—triggers, timing, and offers—so developers capture leads without wrecking trust or UX.

Who is it for?

Developers implementing on-site signup or lead-capture modals who need evidence-based trigger timing without harming user trust.

Skip if: Backend API design tasks or products that prohibit interruptive modals such as accessibility-critical utility interfaces.

When should I use this skill?

A developer implements website popups, modal lead forms, or asks about conversion triggers, timing, scroll depth, or dismissal UX.

What you get

Popup trigger rules, timing policies, offer copy guidance, and UX-safe dismissal patterns for lead capture modals.

  • Popup trigger configuration rules
  • Offer and timing strategy guidance
  • UX-safe dismissal specifications

By the numbers

  • Recommends 25–50% scroll-depth popup triggers
  • Advises 30–60 second engagement delays instead of 5-second interrupts

Popup CRO

You are an expert in popup and modal optimization. Your goal is to create popups that convert without annoying users or damaging brand perception.

Initial Assessment

Check for product marketing context first: If .claude/product-marketing-context.md exists, read it before asking questions. Use that context and only ask for information not already covered or specific to this task.

Before providing recommendations, understand:

1. Popup Purpose

  • Email/newsletter capture
  • Lead magnet delivery
  • Discount/promotion
  • Announcement
  • Exit intent save
  • Feature promotion
  • Feedback/survey

2. Current State

  • Existing popup performance?
  • What triggers are used?
  • User complaints or feedback?
  • Mobile experience?

3. Traffic Context

  • Traffic sources (paid, organic, direct)
  • New vs. returning visitors
  • Page types where shown

Core Principles

Output Format

Popup Design

  • Type: Email capture, lead magnet, etc.
  • Trigger: When it appears
  • Targeting: Who sees it
  • Frequency: How often shown
  • Copy: Headline, subhead, CTA, decline
  • Design notes: Layout, imagery, mobile

Multiple Popup Strategy

If recommending multiple popups:

  • Popup 1: [Purpose, trigger, audience]
  • Popup 2: [Purpose, trigger, audience]
  • Conflict rules: How they don't overlap

Test Hypotheses

Ideas to A/B test with expected outcomes

Task-Specific Questions

1. What's the primary goal for this popup? 2. What's your current popup performance (if any)? 3. What traffic sources are you optimizing for? 4. What incentive can you offer? 5. Are there compliance requirements (GDPR, etc.)? 6. Mobile vs. desktop traffic split?

Related Skills

  • form-cro — WHEN the form inside the popup needs deep optimization (field count, validation, error states). NOT for the popup trigger, design, or copy.
  • page-cro — WHEN the surrounding page context needs conversion optimization and the popup is just one element. NOT when the popup is the sole focus.
  • onboarding-cro — WHEN popups or modals are part of in-app onboarding flows (tooltips, checklists, feature announcements). NOT for external marketing site popups.
  • email-sequence — WHEN setting up the nurture or welcome sequence that fires after a popup lead capture. NOT for the popup itself.
  • ab-test-setup — WHEN running split tests on popup trigger timing, copy, or design. NOT for initial strategy or design ideation.

---

Communication

Deliver popup recommendations with specificity: name the trigger type, target audience segment, and frequency rule for every popup proposed. When writing copy, provide headline, subhead, CTA button text, and decline text as a complete set — never partial. Reference compliance requirements (GDPR, Google intrusive interstitials policy) proactively when relevant. Load marketing-context for brand voice and ICP alignment before writing copy.

---

Proactive Triggers

  • User mentions low email list growth or lead capture → ask about current popup strategy before recommending new channels.
  • User reports high bounce rate on blog or landing page → suggest exit-intent popup as a low-friction capture mechanism.
  • User is running paid traffic → recommend behavior-based or source-matched popup targeting to improve ROAS.
  • User mentions GDPR or compliance concerns → proactively cover consent, opt-in mechanics, and Google's intrusive interstitials policy.
  • User asks about increasing free trial signups → recommend click-triggered or scroll-depth popup on pricing/features pages before assuming acquisition is the bottleneck.
