Overview
Conversion Rate Optimization (CRO)
This skill analyzes marketing pages across seven CRO dimensions - value proposition, headline, CTA, visual hierarchy, trust signals, objections, friction - producing quick wins, high-impact changes, and test ideas by page type. Use it when optimizing conversions on a homepage, landing page, pricing page, feature page, or lead-capture form.
What it does
This skill analyzes marketing pages and provides actionable conversion rate optimization recommendations, first checking for existing product-marketing context, then identifying page type, primary conversion goal, and traffic source before analyzing. The analysis runs across seven dimensions ordered by impact: value proposition clarity, checking whether a visitor can understand what this is and why to care within five seconds, in customer language rather than jargon, and flagging feature-focused rather than benefit-focused copy, or copy trying to say everything instead of the most important thing; headline effectiveness, checking whether it communicates the core value proposition, is specific enough to matter, and matches the traffic source's messaging, favoring outcome-focused, number-specific, or social-proof framing; CTA placement, copy, and hierarchy, checking for one clear primary action visible without scrolling, value-communicating button copy rather than generic labels, and a logical primary-versus-secondary structure repeated at decision points; visual hierarchy and scannability, checking whether a scanning visitor gets the main message and whether images support or distract from it; trust signals and social proof, checking for recognizable customer logos, specific attributed testimonials, case-study numbers, and review scores placed near CTAs and after benefit claims; objection handling, addressing price concerns, fit doubts, implementation difficulty, and reversibility worries through FAQs, guarantees, and comparison content; and friction points, covering excessive form fields, unclear next steps, confusing navigation, unnecessary required fields, mobile issues, and slow load times.
Recommendations are structured into quick wins that are easy and immediately impactful, high-impact changes that need more effort but pay off significantly, test ideas worth A/B testing rather than assuming, and copy alternatives offering two to three options with rationale for key elements like headlines and CTAs. Page-type-specific frameworks cover homepage CRO, focused on clear cold-visitor positioning and a quick path to the most common conversion; landing page CRO, focused on message match with the traffic source and a single CTA with navigation stripped where possible; pricing page CRO, focused on clear plan comparison and addressing which-plan-is-right-for-me anxiety; feature page CRO, focused on connecting the feature to its benefit with concrete use cases; and blog post CRO, focused on contextual inline CTAs at natural stopping points. It suggests experiment categories covering the hero section, trust signal placement, pricing presentation, form optimization, and navigation, with companion reference material for detailed experiment ideas by page type and for form-specific CRO guidance.
When to use - and when NOT to
Use it when optimizing, improving, or increasing conversions on any marketing page or form - homepage, landing pages, pricing pages, feature pages, or lead-capture and contact forms.
Inputs and outputs
Given a page and its conversion goal and traffic context, it produces a seven-dimension analysis with quick-win, high-impact, test-idea, and copy-alternative recommendations tailored to the specific page type.
Integrations
Companion reference files for detailed experiment ideas and form-specific CRO guidance, plus related skills for signup-flow issues, popups, full copywriting rewrites, and A/B testing to validate recommended changes.
Who it's for
Marketers and product teams optimizing a specific marketing page or form who want a structured, prioritized set of conversion improvements rather than ad hoc guesses about what to change.
