在未來幾天內，Google會專門鎖定網頁垃圾做演算法更新，凡違反Google內容品質指導原則者都將降等。這次的更新則因語系的不同而影響3-5%的查詢結果。例如，在英語世界大約是3.1%，而德文、中文，及阿拉伯文則是3%，而波蘭文則約5%。

Google再度更新搜尋排行的演算法。這次所影響的搜尋結果比例雖然只有約3%，但值得注意的是，這波更新完全針對垃圾網頁而來，特別是以「關鍵字填鴨」（Keyword stuffing），及連結欺騙（Link schemes）等手法來提高搜尋排名的網頁。

SEO 也就是「搜尋引擎最佳化」（search engine optimization）的縮寫，適度而有效的SEO能夠讓搜尋引擎機器人更容易爬找網站內容，也讓使用者更容易透過搜尋引擎找到所需要的相關資訊，進 一步的讓更多人連上網站，有助於網站流量的提升。Google表示，所謂的「白帽」（White hat）SEO，的確能夠幫助改進網站的使用性，甚至讓網站速度更快，打造出使用經驗更佳的網站，對使用者及搜尋引擎都是有利的。而這也是Google所 歡迎的SEO。

但「黑帽」（Black hat）SEO就不是這麼一回事，Google以「網頁垃圾」(webspam)來指稱這樣的 SEO，而這也是Google一直以來努力在打壓的。在黑帽 SEO作法裡，經常利用一些不當手段與技術以取得其網頁不該得的搜尋排行與能見度，而這次Google直接點名的手法則包括了「關鍵字填鴨」，及「連結欺 騙」這兩種手法。

所謂的「關鍵字填鴨」是在網頁裡塞滿了關鍵字以提高搜尋排名。連結欺騙則是製造大量無意義的連結以提高網頁排名，例如建立連結農場，或是到處在不相關的內容上張貼連結。

一般來說，Google每一次的演算法更新與搜尋排名調整，主要目的都是要讓使用者能夠找到他們真正需要的資訊，希望讓內容業者專心為使用者做「高品質」內容，而不需去在意演算法就可得到他們應有的回報。另一面則是要能夠過濾掉「低品質」或是「不相關」的內容。

為達成這個簡單的目的，背後技術也相當複雜而多樣。為此Google也持續不斷在更新其演算法。其中去年底的更新，影響了35%的查詢結果，可以說是近期內影響最大的一次，不過該次更新的重點並不在於垃圾網頁的過濾。

這次演算法更新雖然影響不是非常大，但值得注意的是，這波是完全針對垃圾網頁的過濾而來。Google卓越工程師Matt Cutts表示，在未來幾天內，會專門鎖定網頁垃圾做演算法更新，凡違反Google內容品質指導原則者都將降等。在最初的 Panda更新 中，影響約12%的搜尋結果，而這次的更新則因語系的不同而影響3-5%的查詢結果。例如，在英語世界大約是3.1%，而德文、中文，及阿拉伯文則是3%，而波蘭文則約5%。（編譯/郭和杰）

Keyword stuffing

"Keyword stuffing" refers to the practice of loading a webpage with keywords in an attempt to manipulate a site's ranking in Google's search results. Filling pages with keywords results in a negative user experience, and can harm your site's ranking. Focus on creating useful, information-rich content that uses keywords appropriately and in context.
To fix this problem, review your site for misused keywords. Typically, these will be lists or paragraphs of keywords, often randomly repeated. Check carefully, because keywords can often be in the form of hidden text, or they can be hidden in title tags or alt attributes.
Once you've made your changes and are confident that your site no longer violates our guidelines, submit your site for reconsideration.

Link schemes

Your site's ranking in Google search results is partly based on analysis of those sites that link to you. The quantity, quality, and relevance of links count towards your rating. The sites that link to you can provide context about the subject matter of your site, and can indicate its quality and popularity. However, some webmasters engage in link exchange schemes and build partner pages exclusively for the sake of cross-linking, disregarding the quality of the links, the sources, and the long-term impact it will have on their sites. This is in violation of Google's Webmaster Guidelines and can negatively impact your site's ranking in search results. Examples of link schemes can include:

• Links intended to manipulate PageRank
• Links to web spammers or bad neighborhoods on the web
• Excessive reciprocal links or excessive link exchanging ("Link to me and I'll link to you.")
• Buying or selling links that pass PageRank

The best way to get other sites to create relevant links to yours is to create unique, relevant content that can quickly gain popularity in the Internet community. The more useful content you have, the greater the chances someone else will find that content valuable to their readers and link to it. Before making any single decision, you should ask yourself the question: Is this going to be beneficial for my page's visitors?
It is not only the number of links you have pointing to your site that matters, but also the quality and relevance of those links. Creating good content pays off: Links are usually editorial votes given by choice, and the buzzing blogger community can be an excellent place to generate interest.
