What it does

Once installed, the agent reviews a landing page, homepage, pricing page, or lead form (often from a URL or pasted copy) and diagnoses why visitors aren't converting. It checks value proposition clarity, headlines, call-to-action wording and placement, trust signals, objections, and friction, then returns quick wins, bigger changes, test ideas, and alternative headline or button copy. It also loads detailed reference guides for form design and experiment ideas when relevant.

Great for

  • Marketers or founders whose landing page or signup form gets traffic but few sign-ups
  • Product or growth teams planning A/B tests on pricing, hero sections, or forms
  • Designers or copywriters who want a structured critique of a page before redesigning it

Skip it if

  • Teams needing a full copy rewrite from scratch; the skill points to a separate copywriting skill for that
  • Pages with no real traffic or data, since the advice is heuristic and cannot replace measured test results
  • Signup flows, post-signup onboarding, or popups, which the skill says belong to other skills

Try asking

  • “Here's my pricing page URL, why isn't it converting and what should I change first?”
  • “My lead capture form has high abandonment on mobile, what should I fix?”
  • “Give me three alternative headlines and CTA button texts for my landing page and test ideas to run.”
  • “CRO review of this homepage copy for a B2B SaaS product aimed at small agencies.”

Get better results

  • Provide the page type, primary goal, and traffic source up front so the agent can prioritize correctly.
  • Share any existing product marketing context file or analytics data so recommendations are grounded in real numbers.
  • Treat the suggested changes as hypotheses and validate them with A/B tests before rolling out wholesale.
