12 月 18 号开始,发现 adsense 收入下降一大截,网站的很多页面没法显示广告,全部为空白,去 adsense forum 看了看,发现老外也在抱怨: https://productforums.google.com ... place=forum/adsense , 有一个老外接收到了 Google 的回复: https://productforums.google.com ... adsense/znq0TwljSaU : 4 p& \/ |4 x1 s- C% f7 [0 K7 ]& P6 N8 A$ q. y # H: M$ M+ n/ ~3 D: c+ q) q7 A! y J“ 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. - e( \- e1 E% x( m ) X/ U- w e6 c6 gWe detected that your AdX /Adsense account is sending a significant number of ad requests from URLs that are not crawled.

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?? # W6 w; J4 j0 g4 I; K7 i% v/ g5 J1 m& u( n- O# N" K1 p
个人觉得这么做真的非常愚蠢,并不是每个页面内容都是一成不变的,比如一些列表分页,虽然 URL 都是固定的,但是内容可能随时给你冒出一张色情图片出来,难道这样也能“ increase brand safety ”???而且互联网每天新诞生千千万万的新页面,都要 adsense bot 爬了再显示,无论是 Google、广告主还是个人站长,都会损失相当大吧,我看帖子里好多站长都转向 media.net 了, @, M! c4 I: W/ i! e. V2 c& P
