The robots.txt file of Amazon.com specifies various directives for web crawlers. Most of the directives are Disallow rules, limiting crawling access to specific URLs. For example, URLs like /gp/cart, /gp/sign-in, and /dp/manual-submit/ are disallowed for all user agents except for a few specific paths like /wishlist/universal*, /wishlist/vendor-button*, and /gp/dmusic/promotions/PrimeMusic. The robots.txt file clearly outlines which paths are allowed and which are restricted for crawling.
