Google 搜尋檢索和索引作業常見問題
本文整理了 Google 最常收到的檢索和索引作業相關問題,並一一提供解答。
該如何讓 Google 顯示我的網站?
檢索和建立索引都是需要一些時間才能完成的程序,且過程取決於許多因素。一般來說,我們無法預測或保證系統檢索網址或建立索引的時間點,也無法保證系統一定會檢索您的網址或為其建立索引。在 Search Console 中查看網站索引時,請確認您已驗證「www」和「非 www」(例如「www.example.com」和「example.com」) 這兩種網站版本。提醒您,雖然 Sitemap 檔案有助於我們瞭解網站內容,但無法確保網站一定能建立索引或提升排名。
瞭解如何讓 Google 顯示您的網站。
為什麼我的網站沒有建立索引?
一般來說,網站未建立索引最常見的原因就是網站太新,因此請耐心等候,並要求 Google 檢索網站及建立網站索引。
以下是網站或網站部分內容尚未建立索引的其他常見原因:
- 網路上其他網站連至該網站的連結可能不夠多。
- 網站設計造成 Google 不易檢索及建立索引,也有可能網站本身禁止檢索或建立索引。
- 在我們嘗試檢索時,網站可能暫時無法使用。如果遇到這種情況,Search Console 中會顯示檢索錯誤。
- 請確認網站遵守搜尋基礎入門相關規定,且並未遭到入侵或遭到第三方修改。
- 在極少數情況下,造成問題的原因可能是先前在網域名稱中代管的內容。遇到這種情況時,建議您提交重審要求,並詳細說明內容和擁有權異動情形。
- 如果您最近將網站移至其他網址,請務必遵守我們的網站遷移規範。
- 可能因為先前的擁有者或其他擁有網站存取權的人透過 Search Console 要求移除網站。您可以使用移除工具取消這些要求。

我同時在兩個網域提供相同內容,如何讓 Google 知道這兩個網域是同一個網站?
您可以使用 301
重新導向,將替代網域 (example2.org) 的直接流量導向至偏好的網域 (example.com)。這樣一來,Google 就會一律在同個位置查看您的內容,這也是確保 Google (和其他搜尋引擎) 能正確檢索您網站並且建立索引的最佳做法。系統也會透過 301
重新導向正確傳遞排名信號 (例如 PageRank 或連入連結)。如果您打算變更網域,請參閱有關遷移作業的最佳做法。
我是否提供重複內容?這會使我遭到懲處嗎?我該怎麼辦?
一般來說,重複內容「並不」違反 Google 的垃圾內容政策。詳情請參閱揭開「重複內容懲處」的神祕面紗一文。如果您仍有疑慮或想進一步瞭解相關資訊,請參閱以下文章:
使用子資料夾還是子網域比較好?
選擇您最方便整理及管理的做法即可,這不會影響 Google 建立索引及網站排名結果。
驗證網站的程式碼 (譬如使用 W3C 驗證工具) 是否有助提升網站在 Google 中的排名?
否,至少沒有直接影響。不過,將 HTML 中的錯誤清除乾淨,能讓網站在各種瀏覽器中都能順暢呈現,且更容易存取。
我的網站使用的代管服務採用了「遮罩重新導向」或「遮罩轉址」框架。這是否會影響我網站的檢索作業、索引作業或搜尋結果排名?
建議一律直接使用您的網域名稱來代管內容。如果網站使用了採用框架的轉址服務,通常會造成 Google 無法使用網域名稱檢索內容並建立索引,也無法對該內容進行排名。
我變更了網頁中的部分文字,為什麼搜尋結果沒有反映這些更新?
系統需要一些時間檢索網站中的網頁並建立索引。雖然無法強制更新搜尋結果,但以下做法能夠加快更新速度:
我的網站使用 PHP、ASP、CGI、JSP、CFM 等技術製作網頁,Google 仍會為這類網頁建立索引嗎?
會!如果透過這些技術製作的網頁可以顯示在瀏覽器中,且無須另外安裝或啟用特殊外掛程式,那麼 Google 就能順利檢索這類網頁、建立索引及進行排名。只要網頁可供檢索,不論使用哪種技術,都不會影響網頁的檢索、索引及排名結果。
我最近購買的網域曾經與垃圾資訊網站有關聯,該怎麼做才能確保過往的垃圾資訊記錄不會影響我現在的網站?
請在 Search Console 中驗證您的網站,接著查看人工判決處罰報告,瞭解網站是否受到人工判決處罰。

In general, we cannot make\npredictions or guarantees about when or if your URLs will be crawled or indexed. When\nlooking at your site's indexing in Search Console, make sure that you have both the \"www\" and the\n\"non-www\" versions (like \"www.example.com\" and \"example.com\") verified. Keep in mind that while a\n[sitemap file](/search/docs/crawling-indexing/sitemaps/overview) can help us learn about\nyour site, it does not guarantee indexing or increase your site's ranking.\n\n\nLearn how to [get your site on Google](/search/docs/fundamentals/get-on-google).\n\nWhy isn't my site indexed?\n--------------------------\n\n\nIn general, the most common reason that a site is not indexed is because it's just too new; be\npatient and [ask Google to crawl and index it](/search/docs/crawling-indexing/ask-google-to-recrawl).\n\n\nHere are the other common reasons why a website or parts of a website might not be indexed yet:\n\n- A website might not be well connected through multiple links from other sites on the web.\n- The design of the website might make crawling and indexing difficult. Maybe the site itself is even explicitly [blocking crawling or indexing](/search/docs/crawling-indexing/control-what-you-share)?\n- Perhaps it was temporarily unavailable when we attempted to crawl? You might find [crawl errors](https://support.google.com/webmasters/answer/7440203) in Search Console in this case.\n- Verify that the website complies with our [Search Essentials](/search/docs/essentials) and hasn't been [hacked](/search/docs/monitor-debug/security/malware) or otherwise modified by a third party.\n- In very rare cases, it might be that content previously hosted on a domain name is causing issues. In this case, you may wish to submit a [reconsideration request](https://support.google.com/webmasters/answer/35843) detailing the change of content and ownership.\n- If the website recently moved to a different address, make sure that you follow our [guidelines for moving a site](/search/docs/crawling-indexing/site-move-with-url-changes).\n- It's possible that a previous owner or someone else with access to the website [requested removal through Search Console](https://support.google.com/webmasters/answer/156412). You can cancel these requests by using the [Removals Tool](https://support.google.com/webmasters/answer/9689846).\n\n\nFor more information, check out [Why is my page missing from Google Search?](https://support.google.com/webmasters/answer/7474347).\n\nI have the same content available on two domains. How do I tell Google\nthat the two domains are the same site?\n--------------------------------------------------------------------------------------------------------------\n\n\nUse a `301` redirect to direct traffic from the alternative domain (example2.org) to your\npreferred domain (example.com). This tells Google to always look for your content in one\nlocation, and is the best way to ensure that Google (and other search engines) can crawl\nand index your site correctly. Ranking signals (such as PageRank or incoming links) will\nbe passed appropriately across `301` redirects. If you're changing domains, read about the\n[best practices for making the move](/search/docs/crawling-indexing/site-move-with-url-changes).\n\nDo I have duplicate content? Am I being penalized for it? What should I do about it?\n------------------------------------------------------------------------------------\n\nGenerally, duplicate content is **not** a violation of\n[Google's spam policies](/search/docs/essentials/spam-policies). For more\ninformation, read our article on\n[Demystifying the \"duplicate content penalty\"](/search/blog/2008/09/demystifying-duplicate-content-penalty).\nIf you're still concerned or want to know more, read these articles:\n\n- [Dealing with duplicate content](/search/blog/2006/12/deftly-dealing-with-duplicate-content)\n- [Duplicate content caused by URL parameters](/search/blog/2007/09/google-duplicate-content-caused-by-url)\n- [Duplicate content caused by scrapers](/search/blog/2008/06/duplicate-content-due-to-scrapers)\n- [Reunifying duplicate content on your website](/search/blog/2009/10/reunifying-duplicate-content-on-your)\n- [Duplicate content and multiple site issues](/search/blog/2009/09/duplicate-content-and-multiple-site)\n- [Define a canonical page for similar or duplicate pages](/search/docs/crawling-indexing/consolidate-duplicate-urls)\n- [Handling cross-domain duplication](/search/blog/2009/12/handling-legitimate-cross-domain)\n\nIs it better to use subfolders or subdomains?\n---------------------------------------------\n\n\nYou should choose whatever is easiest for you to organize and manage. From an indexing\nand ranking perspective, Google doesn't have a preference.\n\nDoes validating my site's code (with a tool such as the W3C validator) help my\nsite's ranking in Google?\n--------------------------------------------------------------------------------------------------------\n\nNo, at least not directly. However, cleaning up your HTML makes your site\n[render better in a\nvariety of browsers](/search/docs/advanced/guidelines/browser-compatibility) and more accessible.\n\nI'm using a hosting service for my site that uses frames,\n\"masked redirects\", or \"masked forwarding\". Will this affect my site's crawling, indexing,\nor ranking?\n----------------------------------------------------------------------------------------------------------------------------------------------------------------\n\nWe recommend always hosting your content directly using your domain name. Using a\nforwarding service that uses frames will generally make crawling, indexing, and ranking\nof your content using your domain name impossible.\n\nI changed some text on my pages. Why isn't it updated in search results?\n------------------------------------------------------------------------\n\nCrawling and indexing of pages within a website can take some time. While there's no\nway to force an update, here are some tips that may help to speed this process up:\n\n- Ask Google to [recrawl your URLs](/search/docs/crawling-indexing/ask-google-to-recrawl).\n- If you are using a [sitemap file](https://sitemaps.org/), make sure to update the [last modification date](https://www.sitemaps.org/protocol.html).\n- If your site's content is indexed with multiple URLs, [resolving the duplicate content issue within your site](/search/blog/2009/10/reunifying-duplicate-content-on-your) will generally allow crawlers to find updated content quicker.\n\nMy website uses pages made with PHP, ASP, CGI, JSP, CFM, etc. Will these still get indexed?\n-------------------------------------------------------------------------------------------\n\nYes! Provided these technologies serve pages that are visible in a browser, without\nspecial plugins installed or enabled, Google will generally be able to crawl, index,\nand rank them without problems. We have no preference; they're all equivalent in terms\nof crawling, indexing, and ranking, as long as we can crawl them.\n\nI recently purchased a domain\nthat was previously associated with a spammy website. What can I do to make sure that\nspammy history doesn't affect my site now?\n--------------------------------------------------------------------------------------------------------------------------------------------------------------\n\n[Verify your site in Search Console](https://support.google.com/webmasters/answer/9008080),\nthen check to see if there's a manual action in the\n[Manual Actions report](https://support.google.com/webmasters/answer/9044175)."]]
