landing-page-review — Claude Code skill: CRO audit of a landing page

What landing-page-review does

The skill loads a URL and breaks the page into pieces: headline and subheadline, button copy and placement, how clear the offer is, what sits above the fold, how sections are ordered. Each element gets a 1-10 score — headline clarity, how specific the value proposition is, CTA strength, social proof, urgency. Trust signals are checked separately: customer logos, testimonials, security badges, published pricing, contact details, links to policy and terms.

When a form is present, the skill counts its fields, reads the labels and the submit button text, and looks for a privacy note nearby. For mobile it can only read the viewport meta tag and inline CSS. Tap target sizes and the position of the CTA on the first screen need a rendered page, so run the URL through PageSpeed Insights or open it in device mode at 375px wide. Load speed the skill measures itself with curl: time to first byte, HTML size, and a rough total across referenced assets. A TTFB above 1 s or roughly 3 MB of weight costs points.

With Cogny MCP connected, heuristics get backed by numbers: conversion by device and source from GA4 or Plausible, friction points from Microsoft Clarity, past A/B tests from GrowthBook. Every one of those tools is read-only. Without a connection the skill still produces a heuristic score and names what each source would add. Clarity allows 10 requests per day, so get_api_quota runs first.
