The cookies report shows what cookies a site pushed to the crawler during the crawl
Modern cookie law and requirements is a problem for website owners because it's difficult to know exactly what cookies your website is pushing. You've probably installed a cookie manager to get permissions but how do you know that the website still isn't pushing cookies when, for example, a CDN like cloudflare can push cookies without you knowing?
During a crawl with The Crawl Tool, it logs all cookies that a web browser would have been asked to store. It doesn't agree to cookie manager permissions, so it shows you the cookies that are being pushed outside of that. Giving you that picture of what is going on.
The name of the cookie.
The value that the cookie contains
The domain for which this cookie is in scope (applies to). There could, for example, be multiple cookies with the same Cookie name but on different domains.
The path the cookie applies to.
The expiry date of the cookie. When the crawler starts it has no cookies stored, so when taken relatively to the crawl time this can give you an idea of how long a cookie is set to last for.
