" C( {" P1 x5 e/ {7 p6 A“ As part of Google ’ s efforts to increase brand safety for advertisers, Google is making changes to the way it buys impressions on URLs that are uncrawled. More specifically, starting on December 15th, AdWords and DoubleClick Bid Manager will adopt more restrictive bidding on ad requests coming from URLs that are uncrawled. This is necessary to avoid the risk of ads running on sensitive content. 0 P/ k z8 ~, W" n8 Z9 O6 W " R! m- G. h. t* |4 N+ oWe detected that your AdX /Adsense account is sending a significant number of ad requests from URLs that are not crawled.

以前是只要页面放了 adsense，广告就会显示，违规了再给你警告，现在 Google 变了政策了，adsense 页面需要经过 adsense bot 爬了验证了合格再显示广告。 0 l1 r! A6 c. m& N' k7 `$ F" [/ b2 s
为了验证，以 V2EX 首页为例，https://www.v2ex.com 右侧会显示 adsense，但是我们随便加一个参数： https://www.v2ex.com?sdf ，右侧 adsense 广告没了（后续 adsense bot 可能会爬取这个网址后显示广告，你们可以把 sdf 换成随机字符串）， 感觉 Google 真的为了“ increase brand safety ”而不惜断了自己的血本啊，这么做自己也会损失一大截吧，股票还不下跌？？, @" A$ k9 P, K* T1 V; e2 G
