Robots.txt validator
Make sure search bots see exactly what you want on your site. Enter a domain or paste your robots.txt — in a couple of seconds we’ll show the rules, bot access, and confirm everything is open for indexing.
About robots.txt and this checker
robots.txt is a plain-text file at your site root that tells crawlers—search engines, SEO tools, social bots—which paths they may fetch and which they should skip. It steers indexing and crawl budget; it is an agreement with bots, not a way to make a site invisible on the internet.
Why it matters in day-to-day SEO
A syntax slip or an overly broad Disallow can quietly block categories, products, or landing pages you meant to keep open. Teams often notice only after metrics move; validating before deploy and again after go-live closes that gap early.
What SiteVisor does for you
- Load the live robots.txt from a domain or paste a draft before publishing—rules are interpreted the same way as on the real host.
- Add URLs and pick bot user-agents to see allow or deny outcomes side by side, including major search and regional crawlers available in the picker.
- Use the structural summary and issue list to spot risky directives without parsing the raw file line by line.
- Signed-in users keep per-project history of recent checks so you can compare how the file evolved over time.
After a check, it is worth confirming that
- priority URLs are not blocked for the bots that actually matter to your market;
- each User-agent group and path rule reads the way you intended—one typo can invalidate an entire block;
- you re-run the test after publishing changes so the live robots.txt still matches what you validated.
How it works
- 1
Point us at your site or file
Enter a domain and we’ll find robots.txt automatically, or paste the contents yourself.
- 2
Review the rules together
In seconds we lay out User-agent groups, allows and disallows, sitemaps, and delays — clear and organized.
- 3
Check your key pages
Enter the addresses of important pages and confirm they’re open to search engines.
What the check shows
Rules per bot
We read Allow and Disallow directives for each User-agent — Googlebot, YandexBot, and any others — so you know exactly who can access what.
Test specific URLs
Enter any address and instantly see whether it’s allowed to crawl and by which rule. A great way to check key pages before a release.
Sitemap and Crawl-delay
We highlight sitemap links and the declared crawl delay, so bots find fresh content faster and crawl your site gently.
Plain-language hints
Every rule is explained in simple words — no need to memorize robots.txt syntax, we decode it for you.
Draft or live site
Check a future robots.txt before you publish, or the live file straight from your domain — whichever suits you.
