Google Instant Preview

酝酿已久的带网页预览功能的Google搜索结果页终于上线了,谷歌取名“Google Instant Preview”。如下图:

鼠标点击搜索结果后面的放大镜就可以开启或关闭Google Instant Preview功能。当此功能开启时,只要鼠标滑过搜索结果,在右侧就可以显示网页预览结果。此功能关闭时,鼠标单击搜索结果块,也可以打开或关闭网页预览。

据Google统计,Google Instant Preview功能的出现,使得谷歌用户的满意度提高了5%。看来用户对这个功能还是很满意的。从用户的角度来看,当鼠标滑过的时候,出现网页预览,可以让用户在点击进入网页之前对网页有个预先的判断,到底是不是自己希望打开的网页,避免了打开一堆网页而影响用户体验。

作为一个网站站长或SEOer,如何才能更好的利用Google Instant Preview这一功能呢?


  • Keep your pages clearly laid out and structured, with a minimum of distractions or extraneous content. This is always good advice, since it improves the experience for visitors, and the simplicity and clarity of your site will be apparent via Instant Previews.
  • Try to avoid interstitial pages, ad pop-ups, or other elements that interfere with your content. In some cases, these distracting elements may be picked up in the preview of your page, making the screenshots less attractive.
  • Many pages have their previews generated as part of our regular crawl process. Occasionally, we will generate screenshots on the fly when a user needs it, and in these situations we will retrieve information from web pages using a new “Google Web Preview” user-agent.
  • Instant Previews does not change our search algorithm or ranking in any way. It’s the same results, in the same order. There is also no change to how clicks are tracked. If a user clicks on the title of a result and visits your site, it will count as a normal click, regardless of whether the result was previewed. Previewing a result, however, doesn’t count as a click by itself.
  • Currently, adding the nosnippet meta tag to your pages will cause them to not show a text snippet in our results. Since Instant Previews serves a similar purpose to snippets, pages with the nosnippet tag will also not show previews. However, we encourage you to think carefully about opting out of Instant Previews. Just like regular snippets, previews tend to be helpful to users—in our studies, results which were previewed were more than four times as likely to be clicked on. URLs that have been disallowed in the robots.txt file will also not show Instant Previews.
  • Currently, some videos or Flash content in previews appear as a “puzzle piece” icon or a black square. We’re working on rendering these rich content types accurately.

这些英语不难,有兴趣的自己翻译一下看看,顺便提高一下英语。大意就是说,良好的网站结构和布局能让网页预览显示的更好,尽量避免广告页和弹出窗口。Google Instant Preview不会影响Google的网站排名,用户预览了网页不会被算作是用户对网站的一次点击。用nosnippet标签可以避免网页预览的出现。

另外,11月1号的时候,Google站长管理员博客里发了一篇文章:Best Practices For Running Multiple Sites

We suggest not spreading out your efforts too broadly, though. It can be difficult to maintain multiple sites while keeping the content fresh and engaging. It’s better to have one or a few good sites than a multitude of shallow, low value-add sites.
