Hello, I have three questions 1, in the official notes of adsense，they say: The spider/bot used by Adsense is Mediapartners-Google, but I only found googlebot in the website's log and did not find Mediapartners-Google. Why? 2, in Adsense's official description, they say,the adsense/ Mediapartners-Google crawl and googlebot crawl use identical cache / Network snapshot so i want to know whether googlebot and Mediapartners-Google crawl the same content? 3， i know spider/bot also have referer and User agent , in site log,we can detect spider/bot referer, so，which user agent can spider/bot use?chrome,ie,etc?
