如果你说的“搜索引擎”是百度的话,这种情况应该经常发生。
Google有额外的机制保证官方网站即使在PR,流量等逊于其他网站的时候也能排在最前面 |

@rawseed 我对SEO不是太了解,不过前几天在读In The Plex的时候看到的
大意是:如果很多网站用奥巴马做关键字链接到白宫首页,那么即使白宫首页里没有奥巴马这个词出现,Google也会在“奥巴马”的搜索结果里把白宫排在最前面。 Wikipedia上的相关内容在这里 http://en.wikipedia.org/wiki/Anchor_text#Search_engine_algorithms Anchor text is weighted (ranked) highly in search engine algorithms, because the linked text is usually relevant to the landing page. The objective of search engines is to provide highly relevant search results; this is where anchor text helps, as the tendency was, more often than not, to hyperlink words relevant to the landing page. Anchor Text只是一个signal而已,Google有成百上千个signals来共同决定一个网站的ranking:) |
