You can control crawler access using the following methods:
1. Configure the robots.txt File (Recommended Basic Method)
• Create or edit the robots.txt file in the website root directory;
• Restrict specific crawlers or all crawlers through rules, such as blocking access to specific directories or the entire site;
• Suitable for standard search engine crawlers, but has limited effectiveness against malicious crawlers.
2. Use Website Protection Products for Blocking
• Identify and block abnormal crawler requests through protection rules;
• Restrict access based on request frequency, IP addresses, behavioral characteristics, etc.;
• Suitable for defending against malicious crawlers or high-frequency scraping.
Kind Reminder:
• robots.txt is only a protocol-based restriction and is only effective for compliant crawlers;
• For malicious crawlers, it is recommended to combine website protection products or server firewall strategies;
• After configuration, it is recommended to monitor access logs and continuously optimize the rules.
