Simulate search engine spiders to crawl web pages. Check HTTP crawl status, response headers, and view the raw HTML page source online.
This tool uses the selected search engine bot's User-Agent to request the target page and shows you what the bot actually sees.
During website optimization, it is often necessary to verify whether search engine spiders can properly crawl your pages. The Spider Crawl Simulator can emulate mainstream search engine bots like Googlebot, Bingbot, and Baiduspider to send requests to a target URL and return the crawl results. This helps webmasters diagnose website accessibility and spider crawling issues.
Example: Enter https://www.example.com, select Baiduspider, and it returns a 200 status code. The response headers will include Server, Content-Type, etc., and the content will show that the page was successfully crawled.
The entered URL must be publicly accessible; intranet addresses cannot be crawled. There are limits on the frequency of simulated crawls. Please do not send a large number of requests to the same domain in a short period to avoid being blocked by the server. Crawl results are for site analysis purposes only; please respect the target website's robots.txt protocol. This tool does not store your submitted URLs or crawl results.
Spider simulators are commonly used for SEO diagnostics: checking a website's search engine friendliness, verifying if spider IP ranges are mistakenly blocked, or identifying unexpected HTTP status codes. We recommend regularly testing your important pages with different spider types to ensure proper indexing. Common spider User-Agents include: Baiduspider "Baiduspider+(+http://www.baidu.com/search/spider.htm)" and Googlebot "Googlebot/2.1 (+http://www.google.com/bot.html)".
