SEO Landing Page Generator

Generates, audits and fixes dependency-free static HTML landing pages built for 100/100 PageSpeed with full JSON-LD markup.

Marketing & SEOIntermediate★ 131⑂ 11AI score 9/10Last updated: Aug 30, 2026

What it does

  • Turns a brief (domain, target keywords, CTA, contacts, business type) into a single-page static HTML landing: inlined critical CSS, AVIF/WebP/JPEG image sets, full schema.org JSON-LD, zero third-party requests on first load.
  • Ships a whole project folder, not just one file: index.html, robots.txt, sitemap.xml, favicon.png, images/, ASSETS.md (asset rights & provenance) and SERVER-SETUP.md (caching, compression, security headers).
  • Routes every request into one of three modes: generate, audit-only (read-only, never touches project files) and fix-existing (targeted fixes only).
  • Enforces an executable validation contract: W3C Nu validator, existence check for every referenced local asset, JSON-LD parsing, responsive screenshots at 320/768/1280/1920px, Lighthouse (3 runs, median, ≥90), and manual WCAG 2.1 AA accessibility checks — with a hard rule that unmeasured scores must never be reported.

Who it's for

  • Marketers, small business owners and freelancers who need a fast, search-friendly one-pager.
  • Frontend developers working to a strict performance budget (LCP < 2.5s, CLS < 0.1, ≤15 KB JS).
  • Anyone who wants an evidence-backed audit of an existing landing page.

Example uses

  1. "Build a landing page for a dental clinic from this brief" → it asks for the missing domain, keywords and verified address/phone, then produces a project folder with LocalBusiness/Dentist JSON-LD.
  2. "Audit https://example.com against the performance checklist" → per-check pass/fail with the exact command used, BLOCKER: for anything that can't run, and no files modified.
  3. "The hero image shifts on load — fix it" → a targeted fix to the relevant markup, followed by re-validation with measured evidence only.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the SKILL.m folder from the GitHub repo aleksandr-alhoff/seo-landing into my ~/.claude/skills/seo-landing/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/aleksandr-alhoff/seo-landing.git ~/.claude/skills/seo-landing

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Create the skills directory if needed: mkdir -p ~/.claude/skills
  3. Clone the repo into it: git clone https://github.com/aleksandr-alhoff/seo-landing.git ~/.claude/skills/seo-landing
  4. Verify that ~/.claude/skills/seo-landing/SKILL.md and the references/ folder exist (if SKILL.md sits in a subfolder, move that subfolder's contents up one level).
  5. Restart Claude Code and ask something like "build an SEO landing page for…" or "audit this landing page".
  6. Optional but recommended: install Node.js plus Lighthouse (npm i -g lighthouse) and image encoders (cwebp, avifenc or ImageMagick) so the validation gates can actually run.
