What should every robots.txt file include?
At minimum: a User-agent line targeting all bots (User-agent: *), Allow rules for content you want indexed, Disallow rules for admin areas and duplicate content, and a Sitemap directive pointing to your XML sitemap. Avoid blocking CSS and JavaScript files because Google needs to render pages fully to evaluate them. A clean robots.txt is short, deliberate, and contains only rules you understand; long, tangled robots.txt files cause more SEO problems than they solve.
Why should I never use robots.txt to hide pages from Google?
Disallowing a URL in robots.txt prevents crawling, but Google can still index the URL based on inbound links and show it in search results without content. To truly remove a page from search, use a noindex meta tag or HTTP header, and keep the URL crawlable so Google can see the directive. Blocking sensitive URLs in robots.txt actually advertises their existence to anyone who reads the file, which is publicly accessible. Use proper authentication for truly private content.
What are the most common robots.txt mistakes that hurt SEO?
Top mistakes are blocking CSS, JavaScript, or image folders (which prevents Google from rendering the page), accidentally blocking the entire site with Disallow: /, using robots.txt instead of noindex for canonical control, and listing sensitive URLs that attackers then target. Always test rules with Google Search Console's robots.txt Tester before deploying, and audit the file after every CMS or theme change because plugins frequently rewrite robots.txt without warning.
Can I use wildcards and regex in robots.txt?
Limited support: use * to match any character sequence and $ to match the end of a URL. For example, Disallow: /*.pdf$ blocks PDF files. Full regex is not supported. Major search engines all support these wildcards but smaller crawlers may not. Keep wildcard rules simple to avoid unexpected matches that block valuable URLs. Always test with the Search Console robots.txt Tester after writing wildcard rules to confirm they only block what you intended.
Should I have different rules for different bots?
Sometimes. You might allow Googlebot full access while blocking aggressive crawlers like AhrefsBot or SemrushBot to save server resources. Use multiple User-agent blocks. However, blocking SEO tools cuts off your own competitive intelligence options and your competitors will still scrape via cloud IPs that ignore robots.txt. Generally allow major search bots (Google, Bing, DuckDuckGo) and only block bots that demonstrably harm your server performance or scrape malicious data.
Where should robots.txt be located and how is it cached?
It must be at the root of your domain (https://example.com/robots.txt) and accessible via HTTP/HTTPS. Subdirectories or other paths are ignored. Google caches the file for up to 24 hours, so changes can take a day to propagate. To force a refresh after major changes, resubmit through Search Console. Use a CDN cache TTL of 1 hour or less to avoid stale rules during edits, especially during site migrations or temporary maintenance modes.
