There are also cookies that remember more detailed information about you. Perhaps your interests, your web browsing patterns, etc. This means that a site can provide you more targeted content – often in the form of ads. There are types of cookies, called <em>third-party</em> cookies, that come from sites you’re not even visiting at the time and can track you from site to site to gather information about you, which is sometimes sold to other companies. Sometimes you can block these kinds of cookies, though not all browsers allow you to.

还有一些 Cookie 记录了更多关于您的信息，包括但不限于您的兴趣、Web 浏览模式等等。这意味着一个网站可以向您提供更具针对性的内容——通常是以广告的形式。有几种 Cookie 被称为<em>第三方 Cookie</em>，来自于此前您从未访问过的网站，可以做到跨网站跟踪并收集您的信息，这些信息多半会出售给其他公司。有时您可以选择拦截这类 Cookie，但并非所有浏览器都允许您这么做。
