Cro

This analyzes marketing pages and forms to improve conversion rates using a structured framework that prioritizes value proposition clarity, headline effectiveness, and CTA optimization. It checks for product marketing context first to avoid asking redundant questions, then evaluates everything from visual hierarchy to friction points. The output gives you quick wins, high impact changes, and specific A/B test ideas rather than vague suggestions. Works across homepages, landing pages, pricing pages, and lead forms. The framework is opinionated about what matters most (clarity over cleverness, benefit focus over feature lists) and includes page-specific guidance plus form optimization rules. Good if you want actionable CRO feedback instead of generic best practices.
