- 12. Robot detection by HTTP user agent Page Search robot HTTP request 66.249.66.1 - - [04/Mar/2008:00:20:56 -0500] “ GET /2007/11/13/game-plan-what-marketers-can-learn-from-strategy-games/ HTTP/1.1″ 200 61477 “ -” “ Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)” “-” A very simple robot detection technique
- 13. Robot detection by HTTP cookie test Page Search robot HTTP request 66.249.66.1 - - [04/Mar/2008:00:20:56 -0500] “ GET /2007/11/13/game-plan-what-marketers-can-learn-from-strategy-games/ HTTP/1.1″ 200 61477 “ -” “ Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)” “ Missing cookie info ” Another simple robot detection technique, but weaker

- 17. Robot detection by visitor behavior Page Robots differ substantially from regular users when visiting a website Your text
- 18. Combining the best of all techniques Page Maintain a cache with a list of known search robots to reduce the number of verification attempts Label as possible robot any visitor with suspicious behavior Label a robot anything that identifies as such Confirm it is a robot by doing a double DNS check. Also confirm suspect robots User Behavior Check User Agent Check IP Address Check Double DNS check
Notes de l'éditeur
- Hi, My name is Hamlet Batista. Some of you know me from my blog, Hamlet Batista dot Com. I’m sure that everybody here has been taught that cloaking is bad. Today I am here to tell you otherwise. I am here to convince you that you should cloak. Now, before you leave the room for fear of castigation by Google, let me share some practical scenarios where good cloaking makes sense. I will contrast cloaking to other recommended alternatives and show why cloaking is still a better option. Hopefully, at the end of my presentation I will have convinced the search engineers in my panel as well.
