麻烦发下您的网站地址，让我见识下
抱歉，我怕被D被C被采集， 除了小圈子不会公布网站的， 而且我的网站和搜索引擎不鸟meta元素也没什么关系
要查文献的话， google搜seo和meta keywords这类关键词能找到很多的， 比如wikipedia就有
The keywords attribute
The keywords attribute was popularized by search engines such as Infoseek and AltaVista in 1995, and its popularity quickly grew until it became one of the most commonly used meta elements.[1] By late 1997, however, search engine providers realized that information stored in meta elements, especially the keywords attribute, was often unreliable and misleading, and at worst, used to draw users into spam sites. (Unscrupulous webmasters could easily place false keywords into their meta elements in order to draw people to their site.)
Search engines began dropping support for metadata provided by the meta element in 1998, and by the early 2000s, most search engines had veered completely away from reliance on meta elements. In July 2002, AltaVista, one of the last major search engines to still offer support, finally stopped considering them.[2]
No consensus exists whether or not the keywords attribute has any effect on ranking at any of the major search engines today. It is speculated that it does, if the keywords used in the meta can also be found in the page copy itself. With respect to Google, thirty-seven leaders in search engine optimization concluded in April 2007 that the relevance of having your keywords in the meta-attribute keywords is little to none[3] and in September 2009 Matt Cutts of Google announced that they are no longer taking keywords into account whatsoever.[4] However, both these articles suggest that Yahoo! still makes use of the keywords meta tag in some of its rankings. Yahoo! itself claims support for the keywords meta tag in conjunction with other factors for improving search rankings.[5] In Oct 2009 Search Engine Round Table announced that "Yahoo Drops The Meta Keywords Tag Also"[6] but informed us that the announcement made by Yahoo!'s Senior Director of Search was incorrect.[7] In the corrected statement Yahoo! Senior Director of Search states that "...What changed with Yahoo's ranking algorithms is that while we still index the meta keyword tag, the ranking importance given to meta keyword tags receives the lowest ranking signal in our system.... it will actually have less effect than introducing those same words in the body of the document, or any other section."[7] In Sept 2012, Google[8] announced that they will consider Keyword Meta tag for news publishers. Google said that this may help worthy content to get noticed, the syntax of the news meta keyword[9] has subtle difference from custom keyword meta tag, it is denoted by "news_keywords", while custom keyword meta tag is denoted by "keywords".
[edit]
国内SEO产业化也是04～05年后的事， 其实国内纸媒早就报告过keywords没用了(03还是04年10月版的大众软件采访的google还是yahoo工程师)
