Audits XML sitemaps against the protocol and samples your URLs for errors, noindex and redirects, or builds clean sitemap files from a crawl.
Technical SEO
Crawlability, indexing, site architecture, Core Web Vitals, and log-file analysis.
Before a search engine weighs a single word you wrote, it has to crawl the page, render it, index it, and decide it loads well enough to rank. Technical SEO skills work that layer: the crawl traps, the noindex left on by accident, the sitemap that 404s, the hreflang tags pointing at the wrong pages. Core Web Vitals Fixer is the one to open when page experience is the problem: it reads field and lab data for LCP, INP, and CLS and names the images and scripts at fault. XML Sitemap Generator and Auditor checks a sitemap against the protocol or builds a clean one, Hreflang Network Validator untangles international setups, and Crawl-Trap & Facet Detector finds the URL spaces that waste crawl budget. Run a full-site audit first, then let what it flags decide which focused skill you reach for.
Guide: How to use Claude Code for SEO
Built by seoskills.sh
All our skillsCompares each URL's raw HTML with its JavaScript-rendered version in headless Chrome to show the content, links and metadata a crawler would miss.
Pulls real-user LCP, INP and CLS from the Chrome UX Report by URL and device, checks them against Google's thresholds, and flags regressions.
Maps the full hreflang graph across language and region versions and validates return tags, self-references, locale codes and canonical consistency.
Detects URL spaces that grow without limit, such as faceted navigation, calendar loops and session IDs, and recommends robots or canonical containment.
Diagnoses failing LCP, INP and CLS from field data and Lighthouse, names the elements, files and scripts at fault, and ranks the fixes by savings.
Follows every redirect hop for a list of URLs to find chains, loops, mixed 301 and 302 use, and redirects that end in errors or contradict the canonical.
