今天从John Chow的Getting Out Of The Google Supplemental Index读到他的Supplemental有1790页是重复内容的。
让ㄚ琪很好奇也想知道工作达人的Supplemental是多少页？
首先，先跟大家说明Google Supplemental Index是什么东西？英文的维基有Supplemental Result的说明：‘Supplemental Result is a URL residing in Google’s supplemental index, a secondary database containing pages of less importance, as measured primarily by Google’s PageRank algorithm.
The importance of a page is measured by the number and quality of links pointing at it.The degree to which Google trusts a site’s inbound links also influences the importance of a page. If Google detects paid links, for example, it will devalue the links or nullify them completely so that PageRank will not pass to the target page.
A supplemental page will still rank in search results, but only if there are not enough pages in the main index that are returned within the search.’在SEO 部落格 : 网路行销及网路赚钱也有对Google Supplemental Index的介绍，‘Google 的补充索引 (supplemental index) 是 Google 在它的主要索引 (main index) 之外的一个索引。’
对网主来说，网页在补充索引内是不好的，因为在补充索引内的网页排名会比较后面。
我们可以在Google 的网站打入 ‘site:[网站名]‘ 的指令，然后看结果。如果一个网页的URL之后有标明 ‘补充资料’，那就代表这个网页是在补充索引之内。
ㄚ琪大概知道这些意思就迫不期待的下载SEO for Firefox plugin来测测看，
这下可好，工作达人上没有Supplemental，不过总让人感觉有点不妥，所以注意看看维基的说明，‘Google used to place a “Supplemental Result” label at the bottom of a search result to indicate that it is in the supplemental index; however in July 2007 they discontinued this practice and it is no longer possible to tell whether a result is in the supplemental index or the main one.’原来在2007年七月Google已经停用了这项服务了，难怪找不到，呵呵，本来想说藉由这个指标可以作为工作达人处理一些比较差的页面或文章的一个方法，现在没有了，只能说Google把ㄚ琪视为宝的工具都一一拿掉了，像之前的字典也是如此。
再这样搞下去，可能就会逼得ㄚ琪亲自来写程式了，不过ㄚ琪现在还没有迫切性，有比我迫切的朋友请先上，我随后就来。
