What is the difference between robots.txt disallow and noindex?
Robots.txt disallow blocks crawling: Googlebot will not fetch the page. Noindex (in meta robots or X-Robots-Tag) allows crawling but tells Google not to index. Critically, if a page is disallowed in robots.txt, Google cannot see its noindex tag, so the URL may still appear in search results without a snippet. To remove a page from the index, remove the disallow first, let Google crawl and see the noindex, then re-block if desired.
Does blocking a page in robots.txt prevent it from ranking?
Not always. If other sites link to a blocked URL, Google may still index it without crawling, showing only the URL and anchor text in results. This is the famous URL appears with no description issue. To truly remove a page from search, allow crawling and add noindex, or use the Search Console URL removal tool. Robots.txt is for crawl budget control, not absolute index suppression.
How specific should my robots.txt rules be?
Use the most specific path that achieves the goal. Disallow: / blocks the entire site, which is catastrophic if accidentally pushed to production. Patterns like Disallow: /search? or Disallow: /*?sessionid= target only crawl-wasting URLs. Always test rules in the robots.txt tester before deploying. The longer matching rule wins in Google's parser, so a specific Allow: /important.pdf can override a broader Disallow: /pdf/.
Should I block JavaScript and CSS in robots.txt?
No. Google explicitly recommends allowing JS and CSS so its renderer can see the page exactly as users do. Blocking these resources causes Google to render a broken layout, which hurts mobile-friendly classification and can suppress rankings. The old practice of blocking /assets or /js to save crawl budget no longer applies. Allow all rendering resources and use Disallow only for genuinely low-value paths like internal search or filtered URLs.
How often does Google re-fetch robots.txt?
Google caches robots.txt for up to 24 hours typically, longer if the file returns errors or is unreachable. After deploying changes, expect a delay before they fully propagate. If you accidentally disallow your entire site, the damage continues until Google refetches. Monitor Search Console for crawl errors after any robots.txt change, and avoid pushing changes on Friday afternoons where issues might run unnoticed through the weekend.
Can I use robots.txt to hide sensitive content?
No. Robots.txt is publicly readable at yoursite.com/robots.txt, so listing sensitive paths there is essentially advertising them to anyone curious. Use HTTP authentication, server-side access controls, or noindex meta tags on protected pages. Robots.txt is a politeness convention for well-behaved crawlers; malicious bots ignore it entirely. Treat robots.txt as a public crawl-management file, never as a security mechanism.
