3个月前(2008年7月3日)USPTO(美国专利商标局)发布了Google的一个美国专利(专利号20080162260,或见这里),题目是"网络节点的广告定向(NETWORK NODE AD TARGETING)",就像在搜索中利用网页的内容、链接等因素进行重要性的PageRank评级一样,这个专利方法是利用社会化网络成员的帖子、好友等因素进行影响力(Influence)的评估,也许可以称之为UserRank或InfluenceRank。
商业周刊以"让社会化网络有利可图(Making Social Networks Profitable)"为题,对这个Google专利做了报道和分析,并指出这为广告主取得梦寐以求的在线社区提供了新途径——Forrester Research的分析师Jeremiah Owyang说:“[Google]的搜索按最高影响列出网页,他们也就完全有理由把这种做法扩大到在线社区和人群”。有了成员的影响力排序及其共同兴趣,广告主就可以通过Google的广告服务收放自如地进行广告定向。
另一篇报道题为"Google打算对社会化网络的用户进行排序(Google plan to rank social networking users)":社会化网络的用户会被按照他们的影响力来排序——有多少人访问他们的个人页面、他们有多少朋友、他们活跃度怎样、他们属于哪个兴趣组等。社区里最受欢迎的用户被Google称为“影响者”,广告就显示在这些人的个人页面上。“显示在个人页面上的广告数量,取决于成员在社区中的排序”。 (该报道还说,今年以来USPTO已经发布了69个Google的专利,思路很广,从显示邻近商店商品的智能广告板,到漂浮在海面上海浪发电的数据中心。)
