Result Click Tracking

Take bnet as an example, when we search for the keyword "haha", the search result link looks like this:

https://www.baidu.com/link?url=X02KNEaEhaHM-7eY_i6OWGWBZ9_KEYvIlMec91jStRWvcg4uyumrhdefe-ZzdrLKk7iewh9aTfCA1ot-3DbVKq&wd=&eqid=ff666e2e0005fb3e00000006640c00d2

If we click in, the page opening process looks like this

1. accesshttps://www.baidu.com/link
   1. The bnet extracts the url parameters and knows which website we want to visit
   2. bnet extracts other parameters (if carried), and knows which websites we have searched and visited through bnet

      Do not believe? You can use different terminals to search for the same keyword and view the same link line. You will find that the link is a long list of different. The search time is not the only thing that is different, is it? Ha ha

   3. bnet extracts the request header information and knows your terminal information. If you log in as a member of bnet, there will naturally be cookies

      Do you think that bnet got the information and discarded it directly? Or find a place to store it?
      After the storage, it is just stored, and it becomes the company's liability? Or do you want to make money?
      Search 搜索关键词 APIthis keyword may answer you

2. After a comprehensive inspection of "Who are you? Where are you from? Where are you going?", bnet will return you a connection address that you really want to visit and let you redirect it.
   

Well, that's what it takes to click through to a b-net search result. Is not it simple?
