How to use the Crawl-delay directive to reasonably control the crawling frequency of AI crawlers?

When it is necessary to balance server load and AI crawler crawling needs, the Crawl-delay directive in the robots.txt file can be used to reasonably control the crawling frequency, which can clearly specify the time interval between two crawler requests. The specific operation needs to be configured in the robots.txt file in the root directory of the website: first specify the User-agent of the target AI crawler (such as specific AI crawler identifiers like Google-Extended, Bard, etc., or use User-agent: * to cover all crawlers), then add Crawl-delay: [value] (in seconds), for example, "Crawl-delay: 15" means the crawler needs to wait 15 seconds before发起 the next request. When setting, it is necessary to consider the server's carrying capacity (to avoid overload caused by high-frequency crawling) and the content update frequency (highly time-sensitive pages can appropriately shorten the interval). It is recommended to regularly monitor the actual crawling frequency of crawlers through server logs and dynamically adjust the interval value; if it is necessary to optimize the accurate crawling of brand content by AI crawlers, you can consider Starreach's GEO meta-semantic optimization service to improve the relevance and efficiency of content in AI crawling.
