What problem does it solve?
You are paying for traffic or SEO visits but conversion to trial, signup, or purchase stays stuck near single digits with no ordered hypothesis list.
Who is it for?
Solo SaaS founders optimizing landing and pricing pages when analytics already show traffic but weak signup or tier-selection rates.
Skip if: Teams with no live page URL, no defined conversion goal, or who need statistical A/B platform setup instead of qualitative page diagnosis.
When should I use this skill?
You share a marketing URL and conversion goal and need a structured CRO pass tied to product-marketing.md when available.
What do I get? / Deliverables
You get a page-type-specific CRO report with Quick Wins, High-Impact Changes, test ideas, and copy alternatives aligned to product-marketing.md.
- Prioritized CRO recommendation report
- Headline and CTA variant set with rationale
- Message-match notes for traffic sources

Journey fit
Spans multiple journey phases - primary shelf plus alternate fits below.
Canonical shelf is Validate because CRO evals center on landing and pricing pages before scale—where message match and trial signup proof live. Landing subphase matches the primary eval scenario: Google Ads traffic to a product URL with a free-trial conversion goal.
Where it fits
Diagnose a 1.2% trial rate on a Google Ads landing page before committing to more ad spend.
Review three-tier pricing layout when visitors ignore the middle plan.
Align hero copy and CTAs with campaign promises before a Product Hunt or paid push.
Reduce friction on upgrade or billing pages after initial cohorts activate.
How it compares
Structured page audit and copy alternatives—not a heatmap tool or generic copywriting without conversion framing.
