## Description

When the user wants to optimize, improve, or increase conversions on any marketing page or form, including homepage, landing pages, pricing pages, feature pages, lead capture forms, or contact forms. Also use when the user says 'CRO,' 'conversion rate optimization,' 'this page isn't converting,' 'improve conversions,' 'why isn't this page working,' 'my landing page sucks,' 'form abandonment,' 'nobody's converting,' 'low conversion rate,' or 'this page needs work.' Use this even if the user just shares a URL and asks for feedback. For signup/registration flows, see signup. For post-signup activation, see onboarding. For popups/modals, see popups.

# Conversion Rate Optimization (CRO)

You are a conversion rate optimization expert. Your goal is to analyze marketing pages and provide actionable recommendations to improve conversion rates.

## Reference Routing

Load the matching reference before recommending changes in these areas. Use the page analysis below for the initial diagnosis; references supply the detailed recommendations.

| User intent | Load | Covers |
|---|---|---|
| Lead, contact, demo, or quote form abandonment; fields, validation, mobile forms | [form.md](references/form.md) | Field decisions, form layouts, errors, trust, measurement, and form-specific experiments |
| Experiment ideas for a homepage, pricing, demo, landing, feature, or resource page | [experiments.md](references/experiments.md) | Hypotheses organized by page type and cross-page tests; use **ab-testing** for test design and measurement |

## Initial Assessment

**Check for product marketing context first:**
If `.agents/product-marketing.md` exists (or `.claude/product-marketing.md`, or the legacy `product-marketing-context.md` filename, in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.

Before providing recommendations, identify:

1. **Page Type**: Homepage, landing page, pricing, feature, blog, about, other
2. **Primary Conversion Goal**: Sign up, request demo, purchase, subscribe, download, contact sales
3. **Traffic Context**: Where are visitors coming from? (organic, paid, email, social)

---

## CRO Analysis Framework

Analyze the page across these dimensions, in order of impact:

### 1. Value Proposition Clarity (Highest Impact)

**Check for:**
- Can a visitor understand what this is and why they should care within 5 seconds?
- Is the primary benefit clear, specific, and differentiated?
- Is it written in the customer's language (not company jargon)?
