在搜索中找寻更多高品质网站

原文：Finding more high-quality sites in search

Our goal is simple: to give people the most relevant answers to their queries as quickly as possible. This requires constant tuning of our algorithms, as new content—both good and bad—comes online all the time.

我们的目标很简单：尽快地给人们提供最相关的查询答案。这要求不断调整我们的算法，因为新内容（不管是好还是差）一直源源不断的涌现。

Many of the changes we make are so subtle that very few people notice them. But in the last day or so we launched a pretty big algorithmic improvement to our ranking—a change that noticeably impacts 11.8% of our queries—and we wanted to let people know what’s going on. This update is designed to reduce rankings for low-quality sites—sites which are low-value add for users, copy content from other websites or sites that are just not very useful. At the same time, it will provide better rankings for high-quality sites—sites with original content and information such as research, in-depth reports, thoughtful analysis and so on.

我们所做的很多改变是很微妙的，以至于很少有人注意到它们。但在最后一天左右，我们对我们的排名算法做出了相当大的改善，这次改变明显影响了我们11.8%的查询。我们希望让人们知道发生了什么事情。此次更新是为了减少低质量网站（那些对用户附加值低，从其他网站复制内容或者仅仅是不是很有用的网站）的排名。同时，它为高质量网站（那些拥有原创内容和信息，例如研究，深度报道，严谨的分析等的网站）提供更好的排名

We can’t make a major improvement without affecting rankings for many sites. It has to be that some sites will go up and some will go down. Google depends on the high-quality content created by wonderful websites around the world, and we do have a responsibility to encourage a healthy web ecosystem. Therefore, it is important for high-quality sites to be rewarded, and that’s exactly what this change does.

我们不能在不影响很多网站排名的情况下做出重大的改进。一些网站排名的上升或者下降是在所难免的。谷歌依赖于世界各地那些创造高品质内容的网站，我们也有责任鼓励健康的网络生态环境。因此，奖励高质量网站是很重要的，而这也是我们这次改变所做的。

It’s worth noting that this update does not rely on the feedback we’ve received from the Personal Blocklist Chrome extension, which we launched last week. However, we did compare the Blocklist data we gathered with the sites identified by our algorithm, and we were very pleased that the preferences our users expressed by using the extension are well represented. If you take the top several dozen or so most-blocked domains from the Chrome extension, then this algorithmic change addresses 84% of them, which is strong independent confirmation of the user benefits.

值得一提的是，此次更新不依赖于我们上周已经从个人过滤清单chrome扩展中得到的反馈信息。然而，我们确实比较了从算法收录网站的收集的黑名单数据。我们很高兴的是用户通过使用扩展所表现的喜好得到了很好的体现。如果你从chrome扩展中使用了前几十个左右黑名单域名，那么算法将改变这些网址中的84%，这是对用户利益的强大的确认。
So, we’re very excited about this new ranking improvement because we believe it’s a big step in the right direction of helping people find ever higher quality in our results. We’ve been tackling these issues for more than a year, and working on this specific change for the past few months. And we’re working on many more updates that we believe will substantially improve the quality of the pages in our results.

因此，我们对这次新的排名改进很激动，因为我们相信这是在帮助用户找到更高质量结果方向上前进的一大步。我们已经着手解决这些问题一年多了，并且为了这次改变的细节工作了几个月。我们正在致力于更多的更新，我们相信这将大大改善我们的结果中的网页的质量。
To start with, we’re launching this change in the U.S. only; we plan to roll it out elsewhere over time. We’ll keep you posted as we roll this and other changes out, and as always please keep giving us feedback about the quality of our results because it really helps us to improve Google Search.

刚开始，我们仅在美国地区推出此次改变，我们计划随着时间的推移逐渐推广到其他地区。我们将告知你我们所推出的这个和其他的改变。和以往一样，请给与我们我们搜索结果质量的反馈，因为它确实能帮助我们改进谷歌搜索。
