無料オンラインRobots.txtジェネレーター

robots.txt is a file in your site's root directory that gives instructions to web crawlers about which pages they should and shouldn't visit. It follows the Robots Exclusion Standard — crawlers that respect it will follow your rules.

No. Disallowing a URL in robots.txt prevents crawling, but the URL can still appear in search results if other sites link to it. To prevent indexing, use meta robots "noindex" on the page itself.

Common exclusions: /admin/, /wp-admin/, /login/, /private/, /cart/, /checkout/, /account/, /thank-you/, duplicate content paths. Never disallow CSS and JS files — Googlebot needs them to render your pages.

User-agent: * with Disallow: / blocks all compliant crawlers from your entire site. This will cause your site to be de-indexed. Only use this on staging or development sites, never on production.

No. Any non-compliant crawler (malicious scrapers, content thieves) will ignore your robots.txt. Never rely on robots.txt to protect sensitive URLs — use server-side authentication and access controls instead.
