例如:facebook使用非常长的变量进行广告链接。这有什么特别的目的吗?

a.php?
表示它是Facebook上的广告。
如果您查看u
查询字符串,它等于http://goo.gl/NkCrsK&__tn__=...
它是一个带有更多查询字符串值的编码链接。
如果您导航到http://goo.gl,您会看到它是谷歌提供的网址缩短服务。因此u
可能代表URL,而其余的URL都是编码的。
它链接到的特定网址为http://goo.gl/NkCrsK,会将您重定向到http://46.20.14.130/~inanilma/uzmanlari/
这是一个医生网站。其余的查询字符串参数可能与医生在Facebook上注册的广告系列相关,因此他可以跟踪他的点击等。
