What impact does the priority field in the Sitemap have on the crawling order of AI crawlers?

When a website submits content via a Sitemap, the priority field is typically used to indicate the relative importance of pages to AI crawlers, but it is not an absolute factor in determining the crawling order. The field ranges from 0.0 to 1.0 (with 1.0 being the highest) and essentially serves as a subjective label of a page's value by the website. AI crawlers will comprehensively judge crawling priority by combining this with other factors. When processing Sitemaps, AI crawlers primarily use the priority field as a reference signal rather than an executive instruction. The actual crawling order depends more on the page's actual value, including content update frequency, user access data, internal link structure, and semantic relevance. For example, a high-priority page that has not been updated for a long time may be crawled later than a low-priority page that is frequently updated. Different AI crawlers vary in their sensitivity to this field; some systems may downplay its weight and focus more on judging page value through content quality and user behavior data. It is recommended that website operators set priorities reasonably: core pages (such as the homepage and product pages) can be set to 0.8-1.0, and regular content pages to around 0.5. Avoid overusing 1.0, as this can render the signal ineffective. Additionally, it is necessary to enhance the actual attractiveness of pages to AI crawlers by regularly updating content, optimizing internal links, and other methods.
