Google最新演算法更新(Ten recent algorithm changes)

變動又來囉,Google這次不是丟一個特大號的演算法更新,而是一次宣佈了10個演算法小更新。話說小歸小,這些演算法更新還是非常重要的 …

這篇"Ten recent algorithm changes“宣佈了10個演算法更新,我們先將原文摘錄如下:

  • Cross-language information retrieval updates: For queries in languages where limited web content is available (Afrikaans, Malay, Slovak, Swahili, Hindi, Norwegian, Serbian, Catalan, Maltese, Macedonian, Albanian, Slovenian, Welsh, Icelandic), we will now translate relevant English web pages and display the translated titles directly below the English titles in the search results. This feature was available previously in Korean, but only at the bottom of the page. Clicking on the translated titles will take you to pages translated from English into the query language.
  • Snippets with more page content and less header/menu content: This change helps us choose more relevant text to use in snippets. As we improve our understanding of web page structure, we are now more likely to pick text from the actual page content, and less likely to use text that is part of a header or menu.
  • Better page titles in search results by de-duplicating boilerplate anchors: We look at a number of signals when generating a page’s title. One signal is the anchor text in links pointing to the page. We found that boilerplate links with duplicated anchor text are not as relevant, so we are putting less emphasis on these. The result is more relevant titles that are specific to the page’s content.
  • Length-based autocomplete predictions in Russian: This improvement reduces the number of long, sometimes arbitrary query predictions in Russian. We will not make predictions that are very long in comparison either to the partial query or to the other predictions for that partial query. This is already our practice in English.
  • Extending application rich snippets: We recently announced rich snippets for applications. This enables people who are searching for software applications to see details, like cost and user reviews, within their search results. This change extends the coverage of application rich snippets, so they will be available more often.
  • Retiring a signal in Image search: As the web evolves, we often revisit signals that we launched in the past that no longer appear to have a significant impact. In this case, we decided to retire a signal in Image Search related to images that had references from multiple documents on the web.
  • Fresher, more recent results: As we announced just over a week ago, we’ve made a significant improvement to how we rank fresh content. This change impacts roughly 35 percent of total searches (around 6-10% of search results to a noticeable degree) and better determines the appropriate level of freshness for a given query.
  • Refining official page detection: We try hard to give our users the most relevant and authoritative results. With this change, we adjusted how we attempt to determine which pages are official. This will tend to rank official websites even higher in our ranking.
  • Improvements to date-restricted queries: We changed how we handle result freshness for queries where a user has chosen a specific date range. This helps ensure that users get the results that are most relevant for the date range that they specify.
  • Prediction fix for IME queries: This change improves how Autocomplete handles IME queries (queries which contain non-Latin characters). Autocomplete was previously storing the intermediate keystrokes needed to type each character, which would sometimes result in gibberish predictions for Hebrew, Russian and Arabic.
  • 以上這些演算法更新並不是每個都對我們有嚴重影響,其中應該注意的有:

    (1)Snippets with more page content and less header/menu content 搜尋結果將不再只以標題或是選單來顯示網站描述。

    (2)Better page titles in search results by de-duplicating boilerplate anchors 重複樣板式的描點文字將不再會影響搜尋結果標題。

    (3)Extending application rich snippets 軟體類搜尋結果列表的複合式描述內容將擴展。

    (4)Fresher, more recent results & Improvements to date-restricted queries 新鮮內容的選取將更精準。

    (5)Refining official page detection 搜尋官方網站的查詢結果將更精準。

    這五個類別的演算法更新,有三個是關注在搜尋結果的展現方式,有兩個是關注在列表標的網站的選擇。但是「搜尋結果的展現方式」也同樣會影響「列表標的網站的選擇」,因此可以說這五個演算法更新都算是Ranking Factor (評等因素)的修改。

    我們應該如何應對來讓我們的網站適應這些演算法更新更新呢? 相關內容將持續刊登,也歡迎各位多多交流討論。
