TheGuideX SEO & GEO Checker

Check how well any page is set up for search engines and AI assistants — in one click, right in the side panel. TheGuideX SEO & GEO Checker audits the page you are on and grades each check against real thresholds, not vague "good/bad" labels. WHAT IT CHECKS On-page SEO • Title, meta description, canonical, robots meta • Heading structure and hierarchy issues • Internal and external links, nofollow/sponsored, image alt text Answer capsules (GEO) • Select any paragraph, right-click, and grade it as an AI answer capsule — length, directness, self-containedness AI crawler access • robots.txt audit of AI bots: which search and training crawlers are allowed or blocked, stale user agents, invalid groups • llms.txt and ai.txt detection Structured data • JSON-LD viewer with @graph support • sameAs ring and author identity checks • FAQ schema vs visible-text parity Off-site signals • Whether the site has a knowledge-graph entity, how long it has been archived on the web, community mentions, and presence in public web crawls • Optional page-speed check using your own API key HOW TO USE Right-click a page → "Run SEO & GEO check". Right-click selected text → "Check as answer capsule". PRIVACY No server, no analytics, no accounts. All analysis runs locally in your browser.
