Google 在 6 月 7 号时,在其 Twitter 上表示,在近期的 6 月核心演算法更新后,Google 新增加了另一个更新,这次的更新后,会限制搜寻结果当中,同一个网域所出现的次数。
在过去,有很多关键字在其搜寻结果第一页 10 个排名当中,大部分都来自同一个网域的文章。而 Google 听到了大部分使用者的心声,因此决定解决这一个问题 – 透过限制同一网域在同一搜寻结果当中显示的数量。
这样的好处在于,提供了搜寻结果的多样性,让你不必再像以往一样,在搜寻某些关键字时,出现的文章都是出自于某一热门、高权重的网域,而使其内容失去的準确与多样性。
简单来说,在此次更新(我们称它为多样性更新)后,同一网域的网址数量,大约会被限制在最多 2 个之内。
Google 搜寻结果提供网站多样性:
根据 Google 在其官方 Twitte 所言,他们注重搜寻结果的多样性,因此在此次的更新当中解决了这一问题:
Have you ever done a search and gotten many listings all from the same site in the top results? We’ve heard your feedback about this and wanting more variety. A new change now launching in Google Search is designed to provide more site diversity in our results….— Google SearchLiaison (@searchliaison) June 6, 2019
搜寻结果中最多显示两个相同网域的内容
Google 表示,在大部分的情况之下,他们通常不会在搜寻结果当中显示同一网域超过 2 个以上的文章内容。除非 Google 的演算法认为,即使在显示同一网域超过 2 个文章内容的情况下,其内容仍然是搜寻者想要寻找的内容,并能够有效的解决其问题,那么 Google 仍然有可能会显示同一网域超过 2 个文章内容。
This site diversity change means that you usually won’t see more than two listings from the same site in our top results. However, we may still show more than two in cases where our systems determine it’s especially relevant to do so for a particular search….— Google SearchLiaison (@searchliaison) June 6, 2019
子网域与主网域被视为相同
在绝大多数的情况下,Google 会将子网域视为是主网域的一部分。因此在「同一网域不超过 2 个搜寻结果」的条件下,Google 会将 blog.domain.com 与 domain.com 视为是同一个网域。
但是,假设「子网域和主网域具有各自的多样性」,那么搜寻结果仍然有可能会显示超过 2 个相同主网域或子网域的文章内容。
举例来说,你的网站是採用「Blogspot」、「Medium」、「痞客邦」、「WordPress.com」…等等,的部落格系统。在预设情况下,每一个使用者都会有一个该平台独特的「子网域」,例如:「sample.blogspot.com」、「sample.medium.com」、「sample.pixnet.net」、「sample.wordpress.com」…等等。而这些子网域由于是由大量不同使用者所提供各自不同的观点,因此虽然隶属于同一网域的子网域,Google 仍有可能会在其搜寻结果当中显示超过 2 个文章内容。
这就是为什么搜寻美食、旅游相关的关键字时,前 10 名出现的结果大多都是痞客邦的文章内容。
Site diversity will generally treat subdomains as part of a root domain. IE: listings from subdomains and the root domain will all be considered from the same single site. However, subdomains are treated as separate sites for diversity purposes when deemed relevant to do so….— Google SearchLiaison (@searchliaison) June 6, 2019
Google 的 Sullivan 也在其 Twitter 上表示,如果子网域真的具有关键字的高度相关性,它们仍然会将主网域以及子网域分开对待为两个不同的网址,不会混合起来视为是相同网域。
In some cases, we may decide to treat the subdomains as their own sites, if it seems really relevant to. And none of this involves ranking. We don’t mix the domains together or anything. It’s just about the roll-up when we decide for display.— Danny Sullivan (@dannysullivan) June 7, 2019
Yes.— Danny Sullivan (@dannysullivan) June 7, 2019
此次更新与 6 月核心更新不同
Google 同时也表示,这个更新与近期的 2019 年 6 月核心演算法更新不一样。
Finally, the site diversity launch is separate from the June 2019 Core Update that began this week. These are two different, unconnected releases.— Google SearchLiaison (@searchliaison) June 6, 2019
而 Google 的 Sullivan 也在后续表示,以他个人的观点来说,他并不会把这次的调整视为是一次「演算法更新」,因为它不会影响原本排名就很好的网站,这次的更新是为了提供搜寻结果的多样性,显示更多不同网站的结果。
It started a little bit about two days ago but went fully live today. Personally, I wouldn’t think of it like an update, however. It’s not really about ranking. Things that ranked highly before still should. We just don’t show as many other pages.— Danny Sullivan (@dannysullivan) June 6, 2019
此更新仅影响主要的自然搜寻结果
这个「多样性更新」影响的範围仅仅为自然搜寻结果当中的排名,而其他像是精选摘要、我的商家、焦点新闻…等等的丰富片段,则不会受到影响。
It’s about the main listings, not various other displays on the search results.— Danny Sullivan (@dannysullivan) June 6, 2019
Yes. This is only about the main web search listings. It not including things like featured snippets, map listings, etc.— Danny Sullivan (@dannysullivan) June 6, 2019
重複内容不在此次更新的考量当中
Sullivan 表示,这次的更新的重点在于「网域」而非「内容」。因此,我们可以将其理解为:在两个不同网域但有相同的内容情况下,Google 有可能会显示这两个结果。(但实际上这样的说法也不对,两个不同网域相同内容会触发 Google 的重複性内容的演算法,因此排名仍然会因此受到惩罚。这里是想表达这次更新的逻辑以其运作的方式。)
As said in the tweets, it’s focused around domains.— Danny Sullivan (@dannysullivan) June 6, 2019
这次的多样性更新仍会不断改善
Google 表示,这次的更新尚未完善,随着时间的推移,这项多样性更新仍然会持续不断优化改善:
It’s not going to be perfect. As with any of our releases, we’ll keep working to improve it. You might also try it the way someone in Tustin would do it — “nail salons” or “nail salons near me” or “nail salons tustin.” If you’re in Tustin, you know you’re in CA 🙂— Danny Sullivan (@dannysullivan) June 6, 2019
Oh, and I see one of the screenshots has some of those examples! But as said, things hopefully have improved for a variety of searches, and we’ll keep looking to improve.— Danny Sullivan (@dannysullivan) June 6, 2019
Those are completely different domains. Same company; different geo domains. But it’s a good point. I’ll pass this feedback on. We expect to keep improving on the change.— Danny Sullivan (@dannysullivan) June 7, 2019
We’ll be looking to improve. I’ll pass this on.— Danny Sullivan (@dannysullivan) June 7, 2019
