Page layout algorithm improvement
一直以来,我们都致力于帮助您在搜索结果中找到更多优质网站,最近我们对算法做出了新的调整,旨在改进网页布局以及您在点击搜索结果后能够看到的网页内容的数量。
正如
此前提到
的那样,有些用户抱怨说,点击搜索结果后很难找到实际的网页内容,他们对此感到很不愉快。用户希望点击后就能直接看到内容,而不是不停地下拉滚动条,冒出一条接一条的广告。因此,那些没有提供首屏(above-the-fold)内容的网站可能会受到本次算法调整的影响。点击一家网站后,如果您第一眼看到的网页上没有大量的直观首屏内容,或者广告占据了很大的网页版面,这很难称得上良好的用户体验。因此,此类网站的搜索排名也不会很高。
我们知道,对于许多网站而言,在首屏投放广告是一种极为常见的做法;这些广告通常能够收到良好的效果,帮助广告主通过在线内容获利。这次算法调整不会影响到那些以适当的方式在首屏投放广告的网站,但会影响到在主页过度投放广告、以至于用户很难在网页上找到实际内容的网站。此外,改进后的新算法还会影响此类网站:首屏上仅有少量可见内容,或实际内容始终隐藏在茫茫广告之中。
只有不到1%的搜索结果会受到此次算法调整产生的实质性影响。也就是说,在每100次搜索中,普通用户会在不到一次的搜索中注意到搜索结果有所变化。如果您认为您的网站受到了页面布局算法调整的影响,请思量在您的网页使用首屏的方法,以及您网页上的内容是否不够醒目,或很难被用户迅速发现。您可以使用我们的
Browser Size工具
以及
其他工具
,查看您的网站在不同分辨率下的显示结果。
如果您决定更新网页布局,我们的网页布局算法将在重新抓取时自动反映出布局上的变化,并处理足够多的网页,以评估此变化。这一过程所需要的时间取决于多种因素,包括网站上的网页数量、以及Googlebot抓取网站内容的效率。对于普通网站而言,Googlebot可能需要几周的时间抓取并处理足够的网页,以反映网站的网页布局变化。
总而言之,我们建议广告主继续专注于为用户提供最佳的网络体验,而不要执着于具体的算法调整。本次调整只是今年计划推出的总计500项改进中的一项。与以往一样,欢迎您在

This affects less than 1% of searches. Website owners should ensure primary content is easily viewable. Changes to layouts will be reflected after Google re-crawls the site, which may take weeks. The key recommendation is to prioritize the user experience.\n"],null,["# Page layout algorithm improvement\n\n| It's been a while since we published this blog post. Some of the information may be outdated (for example, some images may be missing, and some links may not work anymore). Check out our documentation about [page experience](/search/docs/appearance/page-experience).\n\nThursday, January 19, 2012\n\n\nIn our ongoing effort to help you find more high-quality websites in search results, today we're\nlaunching an algorithmic change that looks at the layout of a webpage and the amount of content\nyou see on the page once you click on a result.\n\n\nAs\n[we've mentioned previously](https://searchengineland.com/google-may-penalize-ad-heavy-pages-100601),\nwe've heard complaints from users that if they click on a result and it's difficult to find the\nactual content, they aren't happy with the experience. Rather than scrolling down the page past a\nslew of ads, users want to see content right away. So sites that don't have much content\n\"above-the-fold\" can be affected by this change. If you click on a website and the part of the\nwebsite you see first either doesn't have a lot of visible content above-the-fold or dedicates a\nlarge fraction of the site's initial screen real estate to ads, that's not a very good user\nexperience. Such sites may not rank as highly going forward.\n\n\nWe understand that placing ads above-the-fold is quite common for many websites; these ads often\nperform well and help publishers monetize online content. This algorithmic change does not affect\nsites who place ads above-the-fold to a normal degree, but affects sites that go much further to\nload the top of the page with ads to an excessive degree or that make it hard to find the actual\noriginal content on the page. This new algorithmic improvement tends to impact sites where there\nis only a small amount of visible content above-the-fold or relevant content is persistently\npushed down by large blocks of ads.\n\n\nThis algorithmic change noticeably affects less than 1% of searches globally. That means that in\nless than one in 100 searches, a typical user might notice a reordering of results on the search\npage. If you believe that your website has been affected by the page layout algorithm change,\nconsider how your web pages use the area above-the-fold and whether the content on the page is\nobscured or otherwise hard for users to discern quickly. You can use our\n[Browser Size](https://browsersize.googlelabs.com/) tool, among\n[many others](https://chrome.google.com/webstore/search/screen%20resolution),\nto see how your website would look under different screen resolutions.\n\n\nIf you decide to update your page layout, the page layout algorithm will automatically reflect the\nchanges as we re-crawl and process enough pages from your site to assess the changes. How long\nthat takes will depend on several factors, including the number of pages on your site and how\nefficiently Googlebot can crawl the content. On a typical website, it can take several weeks for\nGooglebot to crawl and process enough pages to reflect layout changes on the site.\n\n\nOverall, our advice for publishers\n[continues to be to focus on delivering the best possible user experience](https://www.youtube.com/watch?feature=player_detailpage&v=R7Yv6DzHBvE#t=1186s)\non your websites and not to focus on specific algorithm tweaks. This change is just one of the\nover 500 improvements we expect to roll out to search this year.
