How to configure Crawl-budget to prevent AI crawlers from over-crawling low-value pages?

When a website needs to prevent AI crawlers from excessively scraping low-value pages, the core of configuring the crawl budget lies in using technical means to guide crawlers to prioritize scraping high-value content and restrict access to low-value pages. This can usually be approached from four aspects: robots.txt rules, sitemap optimization, internal link structure, and parameter page management. Category/Background: robots.txt settings. Clearly prohibit crawlers from scraping low-value paths (such as duplicate content pages, outdated information pages, test pages) in robots.txt, or use the Crawl-delay directive to control the crawling frequency to avoid wasting crawler resources. Category/Background: Sitemap optimization. Only include high-value pages (such as core product pages, authoritative content pages) in the sitemap and exclude low-value URLs to help AI crawlers quickly identify priority crawling targets. Category/Background: Internal link strategy. Reduce the number of internal links to low-value pages to prevent crawlers from accessing through link depth; at the same time, strengthen internal links to high-value pages to improve their crawling priority. Category/Background: Parameter page management. For duplicate pages generated by dynamic parameters (such as filtering and sorting result pages), use canonical tags to specify the main page, or block meaningless parameter combinations through robots.txt. It is recommended to regularly analyze crawling data through tools such as Google Search Console to identify types of low-value pages that are excessively crawled, and adjust configuration strategies accordingly to optimize the crawling efficiency and resource allocation of AI crawlers.
