Analyze the page across these dimensions, in order of 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)?
Evaluate: - Does it communicate the core value proposition? - Is it specific enough to be meaningful? - Does it match the traffic source's messaging?
Primary CTA assessment: - Is there one clear primary action? - Is it visible without scrolling? - Does the button copy communicate value, not just action? - Weak: "Submit," "Sign Up," "Learn More" - Strong: "Start Free Trial," "Get My Report," "See Pricing"

Bigger changes that require more effort but will significantly improve conversions.
Hypotheses worth A/B testing rather than assuming.
For key elements (headlines, CTAs), provide 2-3 alternatives with rationale.
When recommending experiments, consider tests for:
