更多的在这里,我只关心这一句:

问:Google曾经用过Keywords元字段来决定搜索结果排名吗?

答:简单的说,不。Google在销售的Google Search Appliance确实有使用元标签匹配的功能,且包括Keywords,但这是用于企业内部的搜索,跟我们的互联网搜索完全不同。我们的网页搜索是完全无视Keywords的,你在Keywords里做的所有努力都是徒劳的。

原文如下:

Q: Does Google ever use the “keywords” meta tag in its web search ranking?
A: In a word, no. Google does sell a Google Search Appliance, and that product has the ability to match meta tags, which could include the keywords meta tag. But that’s an enterprise search appliance that is completely separate from our main web search. Our web search (the well-known search at Google.com that hundreds of millions of people use each day) disregards keyword metatags completely. They simply don’t have any effect in our search ranking at present.
