上周，为了摆脱垃圾搜索结果的困扰，谷歌（Google）调整了其搜索算法。谷歌表示，大约12%的搜索会受到此次算法改变的影响。

    那么这次调整对eHow等Demand Media旗下的站点有何影响？据Sistrix统计，eHow完全没有受到影响。而且由于eHow的许多竞争对手，例如Mahalo等内容农场（content farm——一些网站通过搜索优化技术提高排名，但其本身内容质量却很差——译注）网站均受到了冲击，所以Demand Media实际上反而可能从谷歌这次调整中获益。

    经过这番调整，Ehow.com的SISTRIX值甚至还得到了提升（从270升至310），关键字数量也有所上升（从317,320升至324,021）。从上图中的ehow.com搜索结果页分布图中，我们可以看到算法调整前后的差别。这可以算是谷歌对Demand Media网站内容质量的表态吧。

    这对Demand而言是个好消息，但不少人曾期望谷歌彻底清除搜索结果中的低质量内容，看来他们要失望了。

    Last week Google (GOOG) changed its algorithm in an attempt to rid itself of spammy search results. According to Google's post on the matter almost 12% of all searches would be affected by the change.

    So how did Demand Media(DMD) sites like eHow fare? According to results from Sistrix, eHow didn't get hit at all. Furthermore, many of its content farm competitors, like Mahalo, did get hit, meaning that Demand may actually benefit from Google's changes.

    Ehow.com even gained SISTRIX value (from 270 to 310) and Keywords (from 317,320 to 324,021) during the algorithm-change. Looking at the SERP-Distribution chart from above for ehow.com, you'll notice the difference. Quite a statement from Google regarding the quality of Demand Medias' content, isn't it?

    Good news for Demand but maybe a little a bit disappointing for those who expected a wholesale removal of lower quality content.
