Free Crawlability Checker
Find out if Googlebot, Bingbot and AI crawlers can reach your page: robots.txt rules, server status, nofollow, blocked CSS/JS, internal links and sitemap – with step-by-step fixes.
What is a Crawlability Checker?
Crawlability is the ability of search engine bots to access and read a page. A crawlability checker tests everything that can stop a crawler before it reaches your content: robots.txt rules, server errors, redirects, nofollow directives, blocked CSS/JS files and missing internal links or sitemaps.
If a page cannot be crawled it cannot be indexed or ranked – and AI search tools like ChatGPT and Perplexity cannot cite it. This checker applies Google’s robots.txt matching rules exactly (longest match wins) and shows the result for 13 search and AI crawlers.

Common problems and how to fix them
| Problem | Why it matters | How to fix it |
|---|---|---|
| Disallowed in robots.txt | Google cannot read the page. | Remove or narrow the Disallow rule. |
| robots.txt returns 5xx | Google pauses crawling of the whole site. | Fix the server error behind /robots.txt. |
| Blocked CSS/JS | Google renders a broken page. | Allow /wp-content/ and /wp-includes/ files. |
| Nofollow internal links | Pages behind them are hard to discover. | Remove rel=”nofollow” from internal links. |
| Not in sitemap | Slower discovery. | Enable the page in your SEO plugin sitemap. |
Frequently asked questions
What is the difference between crawlability and indexability?
Crawlability means a bot can access the page. Indexability means the page is allowed to be stored in the index. A page must be crawlable first; then noindex, canonicals and quality decide if it is indexed.
Does blocking a page in robots.txt remove it from Google?
No. A blocked URL can still be indexed without content if other pages link to it. To remove a page use noindex and keep it crawlable.
Should I block AI crawlers?
Blocking GPTBot or Google-Extended stops model training, but blocking OAI-SearchBot, PerplexityBot or ChatGPT-User can remove you from AI search answers.
Does Google respect Crawl-delay?
No. Google ignores Crawl-delay. Bing and Yandex respect it.
How often does Google re-read robots.txt?
Google usually caches robots.txt for up to 24 hours.
