Bot FAQ for this IP


Why is baiduspider visiting my website?

Baiduspider is visiting websites as part of its function as a web crawler for the Baidu search engine. The recent activity from IP address 220.181.108.91 shows requests to various pages, using the user agent 'Mozilla/5.0 (compatible; Baiduspider/2.0; +http://www.baidu.com/search/spider.html)'. This crawler indexes publicly accessible content to include it in Baidu's search results. Visits typically occur automatically and are not targeted at specific sites for malicious reasons. To verify the crawler's identity, check the reverse DNS for the IP (should resolve to a baidu.com domain), review server logs for consistent user agent strings, and monitor request frequency. If unwanted, consider updating your robots.txt file, implementing rate limiting, or adding the IP to a blocklist.
