What problem does it solve? Before launching a web project, teams often ship pages with missing meta descriptions, absent sitemaps, or broken Open Graph tags that hurt search indexing and social sharing. This Skill runs a structured technical SEO sweep and reports each finding as PASS, WARN, or FAIL so issues are fixed before launch. ## Core Features & Use Cases - On-page SEO checks: Validates title tags, meta descriptions, single h1 usage, heading hierarchy, internal linking, and image alt text across key pages. - Technical SEO checks: Verifies robots.txt, sitemap.xml, canonical URLs, 404 behavior, redirect chains, URL structure, and the mobile viewport meta tag. - Social and structured data: Audits Open Graph and Twitter Card tags, favicon, and JSON-LD/Microdata schemas such as Organization, Product, FAQ, and Article. - Use Case: When the /launch-check SEO row shows WARN or FAIL, run this audit to get a prioritized table of findings — for example, a missing sitemap flagged as a launch blocker while a missing og:image is a lower-priority warning. ## Quick Start Ask the agent to run an SEO audit on this web project and report any indexing or metadata issues before launch.
