关于 Google 搜索抓取和编入索引的常见问题解答
本文汇总了 Google 最常收到的关于抓取和编入索引问题的解答。
如何让我的网站显示在 Google 搜索结果中?
抓取和编入索引的过程需要一段时间,具体取决于多种因素。一般来说,我们无法预测或保证何时或是否会抓取您的网址或将其编入索引。在 Search Console 中查看某个网站的索引时,请确保同时验证了“www”版本和“非 www”版本(例如“www.example.com”和“example.com”)。请注意,尽管站点地图文件有助于我们了解您的网站,但它并不能保证将您的网站编入索引或提高网站的排名。
了解如何让您的网站显示在 Google 中。
我的网站为何未编入索引?
一般来说,网站未编入索引的最常见原因是网站过新;请耐心等待,并请求 Google 抓取该网站及将其编入索引。
以下是导致网站或网站的某些部分可能尚未编入索引的其他常见原因:
- 网站可能未通过多个链接与网络上的其他网站紧密关联。
- 网站的设计可能使抓取和索引编制难以进行。也许是网站本身明确阻止抓取或编入索引?
- 或许是网站在我们尝试抓取时暂时无法访问?在这种情况下,您可能会在 Search Console 中看到抓取错误。
- 您需要验证并确保网站不仅符合我们的搜索要素指南,而且既未被黑客入侵,也未被第三方以其他方式修改过。
- 在极少数情况下,可能是以前托管在某个域名上的内容导致出现问题。在这种情况下,您可能需要提交重新审核请求,并详细说明内容和所有权变更。
- 如果网站最近迁移到了其他地址,请确保遵循我们的网站迁移指南。
- 可能是前任所有者或能够访问该网站的其他人曾通过 Search Console 请求移除相应网址。您可以使用“移除”工具取消这些请求。

我在两个网域中提供的内容相同,那么该如何告诉 Google 这两个网域是同一个网站?
使用 301
重定向可将来自备用网域 (example2.org) 的流量定向到首选网域 (example.com)。这样可以告知 Google 始终在一个位置查找您的内容,而且是确保 Google(和其他搜索引擎)能够正确地抓取您的网站并将其编入索引的最佳方式。排名衡量因素(例如 PageRank 或入站链接)将通过 301
重定向进行适当传递。如果您要更改网域,请了解迁移网站的最佳做法。
我有重复的内容吗?我会因此而受到处罚吗?我该怎么办?
一般来说,重复内容并不违反 Google 网络垃圾政策。有关详情,请参阅“重复内容处罚”揭秘这篇文章。
如果您仍有顾虑或想了解更多信息,请阅读如下文章:
使用子文件夹或子网域是更好的方法吗?
您应该选择对您来说最轻松的组织和管理方式。从编入索引和排名的角度来看,Google 一视同仁,不会区别对待。
(使用 W3C 验证器等工具)验证网站的代码是否有助于提高我的网站在 Google 中的排名?
不会,至少不会起到直接帮助作用。不过,清理 HTML 能让网站在各种浏览器中获得更好的呈现效果,并且更易于访问。
我的网站使用的托管服务采用了框架、“屏蔽重定向”或“屏蔽转发”,这会影响我的网站的抓取、索引编制或排名吗?
我们建议您始终使用您的域名直接托管您的内容。如果您使用的转发服务采用了框架,则通常会导致我们无法使用您的域名抓取您的内容、将其编入索引并对其排名。
我更改了我的网页上的一些文字,为什么这些文字没有在搜索结果中更新?
抓取网站中的网页并将其编入索引可能需要一段时间。虽然无法强制完成更新,但以下几点提示可能有助于您加快此过程:
我的网站使用通过 PHP、ASP、CGI、JSP、CFM 等制作成的网页,这些网页仍然会编入索引吗?
会!如果这些技术提供的网页在浏览器中可见(未安装或启用特殊插件),Google 通常就可以顺利抓取这些网页、将其编入索引并对其排名,而不会遇到任何问题。只要我们可以抓取这些网页,就会对它们采取完全一样的抓取、索引编制和排名方式。
我最近购买了一个之前曾与垃圾内容网站相关联的网域。如何才能确保垃圾内容历史记录现在不会影响我的网站?
在 Search Console 中验证您的网站,然后检查“人工处置措施”报告中是否存在人工处置措施。

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)."]]
