谷歌 Link Analysis Methods 那 Might Have 更改d

分享是关怀!

Which 谷歌 Link Analysis Approach May Have 更改d?

In the 谷歌 Inside Search blog, 谷歌’s Amit Singhal发表了一篇标题为 搜索质量亮点:2月有40处更改 that told us 关于 many changes to how 谷歌 ranks pages, including the following:

Link evaluation. We often use 链接的特征 to help us figure out the topic of a linked page. We have changed how we evaluate links; in particular, we are turning off a 链接分析方法 that we used for several years. We often rearchitect or 关掉 parts of our scoring to keep our system maintainable, clean and understandable.

Curious 关于 which link analysis method 谷歌 may have stopped using, I decided to look at different link analysis methods I have seen that 谷歌 has used in the past, to try to identify a link analysis approach that they may have stopped using. I couldn’决定他们可能停止了哪一种,但是将所有这些链接分析方法都放在一个地方很有趣。

该图显示了在三个不同网页之间传递的链接的不同值。

A lot of people were guessing which 链接分析方法 might have been changed, from PageRank being 关掉, to anchor text being devalued, to 谷歌 ignoring rel=”nofollow” attributes in links, to others. I was asked my opinion 通过 a few people and mentioned that there were several potential link analysis approaches that 谷歌 might have stopped using.

I’ve made a list of a dozen possibilities and granted 谷歌 patents that describe them, but 谷歌 uses link analysis in a lot of ways, and what 谷歌 关掉 might involve something else entirely, and/or something that might not even be described in a patent.

这里’我的链接分析方法列表:

1.使用本地互连的链路分析

本地 interconnectivity

响应于查询,通常对搜索结果进行排名,然后在将其显示给搜索者之前,先浏览该较小子集中的页面之间的链接,并根据这些结果之间的链接来增强某些结果。

In Plex一书中提到该专利的发明人Krishna Bharat开发了一种类似于 HITS算法 that was incorporated into what 谷歌 does in 2003. This patent was granted in 2003, and it’在很多方面与HITS算法相似。

This process might be somewhat unnecessary these days, especially if 谷歌 is reranking search results based on something like the co-occurrence of terms in a result set based upon 基于短语的索引. – Ranking search results 通过 reranking the results based on 本地 inter-connectivity

2.链接分析以查找相关站点

相关网站

如果您执行的搜索似乎是针对特定网站的,则可能会在搜索结果的底部看到其他页面的列表,标题为(’也是一个链接)“与www.example.com类似的页面”。如果您单击它,您’将会看到[related:www.example.com]的搜索结果。确定哪些页面相关的方法是基于链接的指向,使用基于链接的分析指向这些页面。

A paper 关于 this type of link analysis method, written 通过 a couple of researchers who would end up becoming 谷歌 Employees is 在万维网上查找相关页面

Could 谷歌 have found a better way f finding related pages? It’可能,但显示唐的页面’似乎没有改变。– 使用基于链接的分析查找相关超链接文档的技术

3.使用自适应页面等级的链接分析

自适应PageRank

该专利介绍了一些捷径,它是一种计算PageRank的更快方法。计算PageRank可能需要一段时间,而此处介绍的方法可以加快这种速度。

谷歌 has a lot more pages indexed now than they did when the patent behind this approach was filed, and they may still need this shortcut. They’也有技术上的进步,也许没有。

Adaptive computation of 排行

那里 is a whitepaper that was written 通过 the inventors of this link analysis approach, intended to speed up how PageRank worked and make 排行 at 谷歌 faster. The paper is PageRank计算的自适应方法,由Sepandar Kamvar,Taher Haveliwala和Gene Golub撰写

新增26,2019 –最近有人告诉我们 Former 谷歌 Engineer: 谷歌 Hasn’t自2006年以来使用的PageRank。他说Google于2006年停止使用原始的PageRank,并用名称非常相似但可以更快,更有效地替换它。我猜想自适应PageRank(据估计可以为页面计算PageRank分数的速度快30%)是根据此消息最有可能取代PageRank的链接分析方法。 (我们不 ’我不知道PageRank是否是我在本文开头提到的文章中Amit Singhal所引用的链接分析方法,但是可能是。)

4.跨语言信息检索的链接分析

跨语言信息检索

It might be possible to use anchor text from a link on a page in one language to understand what webpage that link is pointing to in another language, to understand what the targeted page is 关于.

谷歌 has done a lot of work in building 统计机器翻译模型 在过去的5至7年中,该技术可能会比这种方法更好地为他们提供服务。– 使用锚文本作为并行语料库进行跨语言信息检索的系统和方法

5.使用基于链接的聚类进行链接分析

基于链接的聚类

谷歌 has probably clustered similar web pages 通过 looking at other pages that link to pages appearing in search results, and seeing what other pages they link to.

I wrote 关于 this link analysis method in the post How Link Based Clustering Could Allow 谷歌 to Group Search Results

谷歌 might have replaced this clustering approach with one that focuses instead more upon the content and/or the concepts contained on those pages. – 基于链接的超链接文档集群

6.个性化PageRank评分的链接分析

个性化PageRank

根据指向指向针对搜索结果中的特定查询而出现的页面的链接以及这些链接中的锚文本是否与那些查询词相关的链接,确定网页的个性化页面得分。

谷歌 might use a different approach, such as one that may look at large amounts of data 关于 searchers, pages, and queries to calculate a personalized page score for pages. – 在搜索引擎中个性化锚文本得分

我在帖子中更深入地研究了该专利 关于个性化PageRank和个性化锚文本得分

7.基于锚文本索引的链接分析

锚文本索引

Using anchor text for links to determine the 关联 of the pages they point towards. It’s quite likely that 谷歌 continues to use an approach like this, but in a modified manner that might be influenced 通过 things like 基于短语的索引Web搜寻器系统中的锚标签索引

For more details 关于 how this link analysis approach works, I wrote a post 关于 this patent: 谷歌 Patent on Anchor Text Indexing and Crawl Rates.

8.使用历史数据进行链接分析

历史数据

In 2005, 谷歌 published a patent application that describes a wide range of temporal-based factors related to links, such as the appearance and disappearance of links, the increase, and decrease of backlinks to documents, weights to links based upon 新鲜ness, weights to links based upon authoritativeness of the documents linked from, age of links, spikes in link growth, the relatedness of anchor text to page being pointed to overtime.

谷歌 may have used some of the factors described in this patent and continue to use them or replaced them with something else, and it might have ignored others, – 基于历史数据的信息检索

I’ve撰写了有关该专利的一些文章,以及许多延续专利,这些专利更新了其涵盖的链接分析方法的各个方面。我还找到了该专利的一个较早版本(一个临时版本)并进行了撰写,还有一个延续专利,其重点仅在于原始专利中的某些权利要求。如果该专利引起了您的注意,您可能会发现我的文章有趣。它是在: Revisiting 谷歌’s Information Retrieval Based Upon 历史数据

9.链接分析基于页面分段查看链接权重

页面细分

We’ve known for a few years that 谷歌 will give different weights for links based upon segments of a page where a link is located. It’很有可能今天会继续使用类似的方法,但是可能已经以某种方式进行了修改,例如以某种方式限制了链接的传递量,例如,如果链接出现在页脚上,一个网站的多个页面。

Then again, 谷歌 probably has already been doing that. – 基于视觉间隙的文档分割

谷歌 filed a much more detailed patent focused more upon segmentation of any pages, and not just 本地 pages. This patent can be found at: 确定文档在语义上不同的区域

While both of these patents go beyond link analysis, the location of a link on a page can make a difference regarding how much weight a link might carry. I wrote a more detailed post 关于 the second patent at: 谷歌s Page Segmentation Patent Granted

10.基于合理的Surfer模型链接特征的链接分析

合理的冲浪者模型

谷歌’s 合理的冲浪者 model describes a good number of features that might be taken together to determine how much value a link might pass along from a page 关于 other links on that page, and one or more of those values may be no longer considered in a way that they might have been in the past. – 根据用户行为和/或功能数据对文档进行排名

I’ve written a couple of posts 关于 the 合理的冲浪者模型 link analysis approach, because it is an interesting one, and because it was updated at least once. Those posts are:

11.链接分析,查看附属站点之间的链接

附属文件

某些站点可能被视为以某种方式与其他站点相关或关联,例如由同一个人拥有。与其他链接相比,由于这种关系,这些链接的价值可能会降低“编辑确定 links.”

如何计算该从属关系。– 确定链接文档的质量

I wrote 关于 this patent in much more detail in the post: 谷歌’s Affiliated Page Link Patent

12.链接分析与链接页面之间的相关性传播

propagation of 关联

Assigning 关联 of one web page to other web pages could be based upon the distance of clicks between the pages and/or certain features in the content of anchor text or URLs. For example, if one-page links to another with the word “contact” or the word “about”,并且要链接的页面包括一个地址,则该地址位置可能被认为与进行该链接的页面有关。

那里 are a few different parts to this method of having the 关联 of one page on a site propagated to other pages on the same site, and one or more of those could have changed if it is in use. – 在相关网页(例如网站的网页)之间传播有用的信息

I wrote a post 关于 this patent at 谷歌 Determining Search Authority Pages and Propagating Authority to Related Pages

什么“链接分析方法” do you think 谷歌 关掉?

97个想法“Google Link Analysis Methods 那 Might Have 更改d”

  1. Thanks for the thoughts Bill, but 我猜那里 are going to be a lot of ifs and buts, difficult to determine exactly what has changed. Heard a talk 通过 Graham Hansell of CIM yesterday and he said that it was likely the link valuation change was 谷歌 turning off 锚文本索引! Not helpful when speaking to a room full of potential clients.

  2. Its pretty much useful information for webmasters and seo professional to keep an eye on kind of links hey are acquiring and how it recognize as good or bad 通过 谷歌. Thanks for sharing, Hope you would share further detail in future of identified any fix pattern 关于 link evaluation.

  3. 谢谢Bill的出色概述。看来我们可以猜测。 --
    But 我不’仅在二级市场上看不到很多波动。
    保罗,格雷厄姆对他的理论有什么看法吗?他们应该如何找出主题相关性?

  4. 谷歌 is giving less importance in PR. Even if you can have a link in a reputable site 谷歌 may not follow that link, if he “thinks” that it will not have 很好的经验 for the user.
    通过G +在SERP上的集成’s the results will be as personalized as it can get. The target for 谷歌 is “a good experience”。内容农场和链接建设将越来越被禁止。

  5. If you put yourself in 谷歌’在我看来,一会儿(在阅读了威尔·雷诺兹(Wil Reynolds)最近有关链接垃圾邮件的文章之后),最主要的目标肯定是个性化“基于指向在搜索结果中针对特定查询显示的页面的链接以及这些链接中的锚文本是否与那些查询词相关的链接的网页页面评分。”

    This has to be the deepest consideration because ultimately top relevant web content has provided the best in expert advice; providing a self policed network of 权威.

    @马特赖特

  6. 谢谢比尔!与往常一样,很高兴阅读您的文章。我没有找到问题的明确答案,但直到现在为止,我都可以看到锚文本值是完整的。

  7. 显然,我们’re all just guessing (unless Amit would like to leave a comment :-P), but given the importance of SPYW, it is extremely unlikely that 谷歌 “turned off”个性化的PageRank评分(也有很多垃圾邮件处理用途)或使用历史数据的链接分析(尤其是自从新版统一“privacy”政策于今天生效)。

    如果必须从上面的列表中选择一两个,我的猜测将是“本地互连性”和/或“跨语言信息检索”。第一种方法实际上是放大SERP中页面之间链接的影响,如果您’重新寻找使链接贬值的方法(即,“turn off”一种链接分析方法),这将是一个很好的选择。正如Bill所提到的,由于Google具有如此强大的语言翻译系统,第二种方法似乎已经过时了。实际上,我可能会相信Google’网页翻译比我相信其他语言的锚文本的准确性要重要得多。

    @webbstuff

  8. 比尔,谢谢您在这里提出您的想法。昨天我在G +上的Dejan Seo上进行了跟踪,所以这是一个很好的跟进。一世 ’思维#7锚文本索引已更改,目的是摆脱垃圾邮件链接的建立策略。

  9. I think they will devalue the anchortexts and focus on the website theme, surrounding text and other factors that will give 谷歌 a picture of the link instead of the anchortext.

  10. 伟大的文章比尔。有很多可能性可以考虑。即使我没有’为了参加本周的SMX,我提交了“is it anchor text” question for the “询问搜索引擎”今天下午座谈会上,丹尼问了一下。答复是“it wasn’t anchor text –这是另一个链接评估信号”。并非完全有帮助,在这一点上,现在还不知道这是否是真实的陈述还为时过早。

    在接下来的几周内,SEO会尝试通过测试找出乐趣,这将变得很有趣。

  11. 此内容是一部出色的阅读比尔,谢谢您的煽动。

    我认为G将基于数量分析来尝试显着降低锚文本链接的价值。 G已经具有给定域的数据集,因此实现起来相对简单。

    再次感谢

    背风处

  12. My guess is that 谷歌 is reducing the importance of anchor text…SEO可以使用很多很棒的工具来确定“right”可以包含关键字锚点而不触发任何红色标记的链接的百分比。结果,我’我猜这个信号已经贬值了一点(只有我没有证据)。

    此外,它’s not as if 谷歌 can’t从链接的上下文中推断锚文本…I doubt keyword anchor text is essential to determining 关联.

  13. If 谷歌 is really turning off anchor text evaluation, none of the known google bombs should work anymore. this is the ultimate proof and the bombs are still armed 😉

  14. 很有意思。我在2月底左右升级了自己网站上的软件,此后我’ve been getting very poor 谷歌 search 排行s. I had thought it was something to do with the upgrade but now it seems more likely to be the link evaluation changes 通过 谷歌…真的很烦人!

  15. 定位文字会消失,我读过几篇文章说Google也将考虑来自Iframe的链接。

  16. 在我看来,我认为Google对其他我们尚未意识到的因素非常重要,否则我们将对此有一个粗略的概念。最近,我在SeoMOz中阅读了遗嘱一文,并了解了Google的一些重要谎言,例如确定SERP位置时对链接的评估!!我不’认为公关的价值因素会越来越多,因为众所周知,当今Google越来越重视新鲜度以及社交媒体对任何新鲜内容的连接!!谢谢比尔!

  17. Sounds to me like they 关掉 something they had set up and were using for several years but that perhaps wasn’t有任何影响(或稍有负面影响)。

    它可以’它与锚文本一样重要,否则我们会在结果中注意到它。

    By “链接的特征”我将更多地关注标题=链接中的锚点或可能被发送垃圾邮件的东西。也许链接附近的文本是原本的样子’大多数时候是否足够相关?

    With Amit being vague 关于 this one and so clear 关于 the other points it makes you think it might be more important than he’s letting on.

  18. I’我非常确定锚文本完全匹配已经发生了变化。多年以来,我们一直在选择某个关键字,并尝试使用该关键字获得尽可能多的反向链接,从而带来了良好的效果。我在SeoMoz上读了一篇文章,他们进行了一项实验,证明最佳结果来自部分匹配,因此,如果您定位“orange mega 甜食”,而不是获得该锚定文本的10个链接,则应该获得2个“orange 甜食”, 2 with “sweets”, 2 with “mega 甜食”等等。实验证明,部分匹配是更好的长期策略。

    我试图将其应用到我们的链接构建策略中,并取得了显著成果。事实并非如此’很自然总是与相同的锚文本链接…

  19. 那’s exactly 对, Rafeal – and I actually read the same 文章 :). Variation in anchor text is very important. However, in my ideal world, anchor text would have very little impact as a 排行 factor, as it simply encourages spam.

  20. 如果不是’t#11关联站点之间的链接,有时会存在。创建一堆虚假的具有虚假内容的博客作为个人链接服务器的实践注定是一种成功的策略’具有长期价值。

  21. Bill, if I am to take a pick from your list it would have to be #3. Adaptive Pagerank was made redundant since introduction of a new link graph processing framework at 谷歌.

    参考文献:

    Pregel framework was used at 谷歌 even prior to 2009 (when they decided to share it outside 谷歌). So the pattern fits.

  22. I used to think that calculating QB ratings were difficult, the aver per completion etc. thenI began reading 关于 SEO, makes QB ratings simple… I did see a comment above talking 关于 anchor text and I have just never been able to put together why that should be a factor in SEO..

  23. pingback的:NedÄ›lnÃÄtenÃ-týdenÄ。 9. | Linki-关闭页面SEO
  24. 保罗,你好

    自网页创建之日起,Google就使用链接文本作为确定网页相关性的一种信号,尽管它’s likely that they’我们会在不同情况下随着时间的推移进行统治,以防止滥用它。最明显的例子是Google Bombs,人们可能会尝试就特定页面发表政治或社交声明,甚至是在开玩笑(这可能是第一个Google Bomb的意图)的一部分。据说Google过去曾采取一些措施来限制Google Bombs。谷歌’的基于词组索引的专利也明确指出,可以将其用于限制Google Bombs的使用。

    也有可能像 合理的冲浪者 这种方法不仅可以用于限制PageRank,还可以用于超文本相关性。那里’在网络上,关于精确匹配域的讨论也很多,在某些情况下,锚文本相关性可能会在这些方面起到很大的促进作用。是域内关键字的出现引起了这种提振,还是当某人使用域名链接到这些页面时,他们正在利用其中的锚文本的好处? 谷歌已获得一项专利,该专利可能会减少 完全匹配域的好处, at least in cases where 谷歌 might identify a commercial query involved.

    I’m not sure that I would state that 谷歌 probably stopped paying attention to anchor text in front of a room full of potential clients, or at least not with some mention of the kinds of steps that they appear to have taken in response to 谷歌 Bombs and exact match domains.

    此外,虽然基于词组的索引可能会限制诸如Google Bombing之类的功能,但某些网站具有指向此类内容的特定类型的锚文本太多,甚至可能存在某个阈值,甚至’有影响。例如,搜索“click here”即使单词“ don”不显示,您仍将adobe reader下载页面作为最佳结果’t出现在页面上。在Google炸弹实例中,锚文本指向了乔治·布什的白宫传记。“miserable 失败,”阻止它的算法努力一直有效,直到有人添加单词为止“failure”页面的内容。在基于短语的索引方法下,使用指向与页面内容相关的页面的锚文本可能会使该页面与该术语相关。

  25. 嗨,亚历克斯,

    谢谢。 I might post another post or two 关于 other link evaluation methods that 谷歌 might be using. The ones I listed are some of the ones that they may have been using in the past, and may still be using, but there are others as well.

  26. 嗨Nedim,

    有根据的猜测’只要我们意识到搜索引擎可能在做很多事情而没有 ’t know 关于, and may never find out 关于. Things that might be trade secrets, or described in unpublished patents, or in whitepapers that are distributed internally within 谷歌 only.

    我们当时’t given any indication of the scale of the impact that discontinuing the use of that specific 排行 algorithm might have like we were with a couple of the Panda updates, or the 谷歌 Freshness update (now 36% 新鲜er results). It’它之所以被淘汰,原因之一可能是它可能没有产生太大的影响,或者是因为它所做的事情在某种程度上被其他方法所多余。

    那里 are other ways that 谷歌 could discover topic relevancy, from a quick and dirty categorization 通过 looking at words within URLs (there’s a 谷歌 whitepaper on the topic, but it’s probably unlikely to be used in that manner), to a 基于短语的索引 co-occurrence approach, to clustering based upon content and/or similar links, to looking at query terms that pages are 排行 for, as well as others.

  27. 嗨,Alf,

    你什么’re suggesting sounds like something that 谷歌 has been doing for at least a few years already – not having links pass along an equal amount of PageRank on a page under an approach that might be similar to what is described in the 合理的冲浪者 patent. Definitely a good change, but 我不’t think it’s the one that they just made recently. I believe Matt Cutts has been saying that 谷歌 hasn’一会儿一直在平均称重链接。

  28. 嗨,托马斯,

    您’re welcome. I’m ruling out that 谷歌 stopped looking at anchor text as well. It still seems to be having an impact. If it didn’t, I suspect that we would be hearing a lot more people screaming 关于 the change.

  29. 嗨史蒂夫,

    我不’认为阿米特(Amit)会停步并填补我们中的任何一个。很好,但是我怀疑’不会发生。

    个性化的PageRank评分可以在搜索结果中引入网页,而不必将其作为社交搜索结果。一世’我不确定SPYW的结果是否一定会是适当的替代品,而且我怀疑由于个性化而导致的提升页面如果不是的话往往会更好’只是你的页面’我已经去过。通过向您显示链接到搜索结果中页面的页面,我可以看到该方法如何将某些垃圾邮件页面引入个性化结果’ve seen before. I’我想知道是否某些内容过滤比仅关闭该方法更好地阻止了该问题。

    那里 are a few different methods under the historical data approach that we might not notice as gone, especially if 谷歌 made some other tweaks involving things like 新鲜ness.

    但是我’m leaning toward the 本地 inter-connectivity and the cross language approaches at this point as well, and I’m not sure if we would notice too much of a change if they were 关掉.

  30. 嗨,达伦,

    谢谢。 Happy to see you come over here from that post. Anchor text 关联 does seem to be one of the methods of link analysis that people catch on to easily, and attempt to abuse, and it appears to often have a impact. Still, I’m not seeing any signs that it has gone away, and that might be one of the link analysis methods that if 谷歌 stopped using it, we might see the biggest impact from.

  31. 您好Jan-Willem,

    不会’t the text surrounding anchor text be as easy, or almost as easy for people to try to spam as anchor text might be? I think if 谷歌 still looks at it, and looks at some of the other factors that you mention, that might help them determine how much weight to give to anchor text. If the theme of a page, and the text around a link is 关于 cars, and the anchor text within the link is 关于 ice cream, then maybe the anchor text 关联 shouldn’例如,在这种情况下,它的数量就很高。

  32. 李嗨

    I’我猜这在某些情况下可能会有所帮助,但如果分析是针对整个领域本身的,那么在其他情况下可能不会那么有用。例如,在一个在线报纸或杂志或小组博客的站点上,该站点着重于各种主题,如果该页面或帖子或文章本身与该主题有关,并且锚文本与该页面本身相关,则该页面计数较少,因为该领域的主题多种多样?

  33. 嗨杰森,

    我不’t know that there’一种确定“right percentage”包含某些锚文本的链接,但是我绝对希望看到这些工具制造商提供的关于如何得出这样精确数字的解释。听起来有点像有人采用了旧的完美页面SEO工具方法,该方法忽略了SEO的页面外元素,并尝试通过某种方式添加页面外因素来增强它们。

    我见过许多实例,其中链接的上下文不是’一定会有助于您使用实际的锚固测试。但是,如果是这样的话,与仅使用锚文本或将锚文本与该上下文中的其他因素进行比较相比,这可能是一种计算量巨大的方法,’它。我确实在那里’如果锚定文本作为排名信号的攻击成本可以显着提高,则在锚文本中仍具有相当大的价值。

  34. 嗨,

    I’我仍然在搜索[点击此处]的过程中看到Adobe下载页面,即使从技术上讲’t a 谷歌 Bomb. It’只是通过使用该短语的很多页面链接到。

  35. 嗨,艾伦,

    谢谢。 Good to hear that you were able to get that question in. 我不’t think we’ll every get an answer directly from 谷歌, and they might end up regretting that if if means that all of us spend more time testing the many different link analysis methods that they might be using.

  36. 嗨,philbydevil,

    When you see changes in 排行s, it could be due to something you’ve done, something your competitors have done, changes made at a search engine, or even changes involving what people are searching for. Since you noticed lowered 排行s after the changes you’ve made, it’s probably a good idea to check over those and what their potential impact might have been pretty carefully, even with this announcement of multiple changes from 谷歌.

    Is 谷歌 crawling all of the pages that it should be? Did you introduce the possibility of more than one URL for the same pages? Did things like your titles, your meta descriptions, anchor text in your links, and so on change? Is your site slower? Might you have added elements to pages that make them less user friendly in some manner?

    I’我们见过人们做一些事情,例如离开“Disallow: /”之前位于开发服务器上其网站上的robots.txt文件中,告诉搜索引擎不要抓取其任何页面。它’值得检查类似的事情。

  37. 嗨,Nayan,

    搜索引擎使用锚文本已有很长时间了,但是它却可能被想要操纵搜索排名的人们所滥用。它没有’不过,这似乎是Google停止使用的链接分析方法。我确实在几个地方看到过一些关于Google如何处理iframe内容的讨论,并且可能正在努力更好地理解它们,尤其是因为它们易于滥用,例如可能将恶意内容传递到网页(特洛伊木马马,病毒等),但我不知道’认为这与Google关闭的链接分析方法有关。

  38. 嗨,阿杰,

    40个算法更改的列表中确实包含了很多新鲜度,如果我们想跟上这个主题,’s possible that 谷歌 might have changed how it determines whether a page is “fresh”是否基于链接分析方法。

    谷歌 also does seem to be looking at a lot more social signals, but it might just be using those in social search at this point, and possibly doing a lot of testing to see how they could potentially be used for web search 排行s in different ways, and if that helps provide better web search results.

  39. 嗨,马科斯,

    I’m tempted to agree with you that it might not have been something so significant otherwise there would be more people talking 关于 the impact. Then again, as you note the other hand, the announcement did seem purposefully pretty vague.

  40. 嗨,马特,

    I do often see many instances everyday where people are attempting to use anchor text to manipulate 排行s, usually in my blog comment spam bin. 但是我 think it still has some significant positive value as well, and that search results would be worse without hypertext relevancy being a 排行 factor

  41. 嗨拉斐尔和马特,

    您描述的方法非常适合基于短语的索引编制,在该索引编制中,将相关术语或短语链接到锚文本中的页面可能会产生积极的影响。那不会’t necessarily be something I would see 谷歌’s head of search announcing as a link analysis method that 谷歌 was discontinuing, though.

  42. 嗨,塔德

    我想我们’ve already seen 谷歌 implement an approach where they might limit the amount of PageRank passing between links on sites that they might think are affiliated in some manner, whether for spam purposes, or even legitimate ones like common ownership of those sites.

  43. 嗨,丹,

    I would call that a good guess based the speed and scalability of Pregel and upon the way the announcement was worded. Do you think we would notice much of a difference in the 排行s of pages if 谷歌 replaced the Adaptive approach with the use of Pregel? 自从Pregel使用了一段时间以来,这是他们早已做过的事情吗? 如果这是他们所做的更改,他们是否会做出一些模棱两可的声明?

  44. 嗨,迈克,

    您 might actually enjoy a paper 关于 football statistics that I ran across in a search engine patent last November:

    独立于胜利幅度的大学橄榄球队排名的惩罚最大似然法

    It’有趣的是,我们当中有多少人是第一次通过体育运动,特别是棒球运动来介绍一些统计数据。

    这里’s what Page and Brin wrote 关于 PageRank and Anchor text in 大型超文本Web搜索引擎的剖析:

    如今,网络搜索引擎用户面临的最大问题是他们获得的搜索结果的质量。虽然结果常常很有趣,但却扩大了用户范围’视界中,他们常常令人沮丧,并浪费宝贵的时间。例如,搜索的最高结果“Bill Clinton” on one of the most popular commercial search engines was the 比尔·克林顿 Joke of the Day: April 14, 1997. 谷歌 is designed to provide higher quality search so as the Web continues to grow rapidly, information can be found easily.

    为了实现这一目标,Google大量使用了由链接结构和链接(锚)文本组成的超文本信息。 谷歌还使用邻近性和字体信息。虽然很难评估搜索引擎,但我们主观上发现Google返回的搜索结果质量要高于当前的商业搜索引擎。通过PageRank对链接结构的分析使Google可以评估网页的质量。使用链接文本作为链接所指向内容的描述可帮助搜索引擎返回相关的(并在某种程度上为高质量)结果。最后,邻近信息的使用大大提高了许多查询的相关性。

  45. Guys, 我不’t know 关于 anchor text 关联 but 谷歌 sure turned things up a notch in terms of their anchor text density thresholds. Ever since 3.3 came out, I’ve注意到很多链接少的站点击败了更多权威站点(链接多了)。但是,这些授权站点的页面上有许多相同的锚点,但是它们都没有’不一定要受到惩罚,但更喜欢给予较少的偏爱。这里发生了什么事。

  46. Another one great 文章. Everytime i came here, i learn something new. 我不’没有时间制作自己的analisys,所以’对我来说非常有用。再次感谢。而且您是唯一一个回答所有评论者的seo博客-顺便说一句,基于短语的索引编制在不久的将来会变得越来越复杂

  47. 锚文本中的部分匹配肯定会比大量完全匹配更强大。但是,在将锚文本发布到一个充满客户的房间之前,确实需要仔细研究锚文本的消失。

  48. I feel that the Personalized Pagerank scoring may be even more relevant now because of the emphasis 通过 G on personalizing a visit to what the searcher types in. This will continue to become a very interesting subject as 谷歌 PSYW continues to target personal searches and results become more relevant to what you are searching for. IMO.

  49. As a few other people have mentioned above, I have also read some other supporting 文章s 关于 the change in Anchor Text Indexing.. However, all of what we speculate are just educated assumptions (as mentioned 通过 Bill) but I’确保有根据的猜测总比没有好得多!只有进一步的时间和研究,我们才能确定其中的一些变化。

  50. Do you think we would notice much of a difference in the 排行s of pages if 谷歌 replaced the Adaptive approach with the use of Pregel?

    不,它可能处于多余状态,并被新算法覆盖,因此’这就是为什么他们进行清理以释放资源并简化维护工作的原因。

    自从Pregel使用了一段时间以来,这是他们早已做过的事情吗?

    是的,咖啡因会发生这种情况。

    如果这是他们所做的更改,他们是否会做出一些模棱两可的声明?

    它没有’t匹配100%,因为丢弃的分析方法是指发现链接页面的含义。 Pregel框架更新不但适用于所有其他方面。我们’在这里处理少量信息,可能永远不会知道。

  51. 我认为这与精确匹配锚文本有关“vote” for pages. 谷歌 has more then 500+ 排行 signals and they have been testing this for over a year now.

  56. 我很难看到Google放弃了PR。我已经做过几次搜索与我的婚礼摄影师网站相关的关键字。每当我找到一个网站时,我都无法解释为什么它排名如此之高以至于它具有很高的PR值。

  57. I think the G+ influence has yet to be felt. 那里 may have been tweaking to link importance in February but I cannot see how 谷歌 can make any sort of large scale changes until they see how G+ is panning out. And as it – and 本地 search – are not completely world-wide (no 本地 search in France where I am) there is no way 谷歌 will/can itroduce a major shake-up in their algorithm. Maybe in 6 months however!

  61. 嗨,机甲

    It’s not necessarily the amount of links that matter, and it never really has been. One link from the 对 place can be worth many thousands from others. 那’是PageRank流程本身的核心。

    您如何定义“authority” page? If it’通过指向它的链接数,我会尝试找到不同的定义,因为那样’似乎是搜索引擎使用的。

  62. 嗨Dimitar,

    谢谢。基于短语的索引绝对值得花一些时间。一世’我还看到越来越多的迹象表明, 基于概念的索引, of a type possibly similar to that developed 通过 the people who came to 谷歌 via the acquisition of Applied Semantics may play a stronger role in how 谷歌 indexes content.

  63. 嗨Eliseo,

    Under something like 基于短语的索引, partial matches of anchor text, or even the use of related terms (words or phrases that tend to co-occur in pages that might rank well for a particular query) could potentially play a larger role in how much hypertext 关联 or even PageRank might be passed along 通过 links. I wouldn’以便迅速宣布锚文本的死亡。

  64. 嗨Vinny T,

    I definitely believe that 谷歌 sees significant value in personalization, and in seeing how a personalized link analysis might help them deliver better personalized results. I suspect that we might see more emphasis on social sharing signals to help 谷歌 determine what to show as results during personalization, like in the search plus your world approach from 谷歌, and maybe a little less reliance on the kind of link analysis described in the particular patent that I linked to.

    当然,像上面的大多数专利一样,我们不会’t know for certain how much of what they describe 谷歌 has ended up using, but it’s likely that even if 谷歌 was using some type of similar link analysis for personalization, the social signals that 谷歌 seems to be increasingly using may play a larger role than ever before.

  65. 嗨,拉里,

    谢谢。我最喜欢看这篇文章中的专利的事情之一是’他们提供的答案太多了,而是他们有可能带领我们解决的问题。在涉及的特定链接分析方法方面,我们可能永远不知道Google到底发生了什么变化,但是如果查询可以帮助我们更好地了解Google和其他搜索引擎可能如何以不同方式使用链接来帮助他们索引并显示搜索结果,我认为我们都将从中受益。

  66. 嗨,丹,

    I’m guessing that Pregel might have been introduced around the same time as caffeine as well, based upon the dates of the links providing information 关于 it.

    但它 ’s definitely the kind of information that I was hoping might come up in the comments to this post, so thanks for adding it to the discussion. We probably will never know exactly what 谷歌 dropped, but if we can get a better idea of the possibilities, 我想我们 all benefit.

  67. 嗨约瑟夫,

    I’ve been hearing “超过200个信号”像Matt Cutts这样的Google代表已经有很多年了,但是我’d猜想这个数字可能还要高得多。微软在2005年左右发表的有关Ranknet方法的论文之一提到在其机器学习方法中使用500多个信号对搜索结果中的页面进行排名。随着Panda的升级,Google似乎也正朝着机器学习的方向发展,其中涉及的信号数量可能超过数百。

    我确实认为’s possible that 谷歌 has experimented with different weights and approaches to exact anchor text matching, including the use of stuff from 基于短语的索引, but 我不’t think they’我们已将其作为链接分析方法。

  68. 你好乔纳森,

    如果有根据的猜测可以帮助您提出一些好的问题,并在您提出问题时提出’重新探索搜索结果,优化页面并浏览网络分析,它们会变得非常宝贵。 --

  69. 感谢您的伟大想法。我认为更多的是个性化页面排名得分或类似的得分。它’s hard to tell and we can only speculate, while 谷歌 sits on the truth and playing with our minds, bastards ;-).

  70. 嗨柯蒂斯,

    我不’认为Google也不会停止使用PageRank,并且它 ’这不是我在帖子中建议的内容,尽管我确实包括了有关自适应PageRank的一项内容,这可能是Google过去可以用来加快页面PageRank计算速度的一种方法。自成立以来,Google越来越多地在其网页排名中加入了许多新的排名信号,但事实并非如此’看这点他们’已停止使用PageRank。

  71. 嗨西蒙,

    感谢您添加您的观点。我们将Google+引入了社交搜索结果中,但是我希望Google花费一些时间来考虑他们如何最好地利用它来影响社交搜索之外的Web搜索结果。我怀疑他们引入的作者身份标记可能会在这一点上起主导作用。例如,如果某人发布了与Google Plus帐户相关联的内容,而Google在其他地方遇到了相同的内容,那么如果他们不这样做,他们可能会更重视与Google Plus帐户相关联的内容’没有理由相信这是假的个人资料。

    我没’不知道本地搜索不是’目前无法在法国或法国的至少部分地区使用。我没有’尽管在对本地搜索结果进行排名中可能涉及链接分析的某些方面,但请在上面的列表中包括本地搜索结果。但是链接分析没有’似乎对本地搜索的影响与对Web搜索的影响相同。我不’认为Google会宣布这一点是因为他们已经使用了数年的链接分析方法,而这种方法主要影响了本地搜索。他们还提到他们已对本地搜索进行了更改,从而带来了更多“local”结果显示在自然的网络结果中。

  72. 嗨,托马斯,

    您’re welcome.

    我猜那里’搜索引擎有些复杂,这是无可避免的。 --

    谷歌 has had years to get that way, but I’d宁愿看到它们做事的复杂性,也不愿像我们90年代做的那样简单得多的搜索引擎’产生非常相关的结果。

  73. Hi 托马斯·R,

    I suspect that 谷歌’他们可能已经停止使用的任何特定链接分析方法的终止可能在很长一段时间内仍然是个谜,但也许该公告标志着一个好时机,使我们可以更深入地研究他们过去可能使用的某些不同方法。

    I’m not sure that 谷歌 would diminish the value of links from blogs or directories across the board, but rather might change the way that the calculate the value of links from those sources.

  74. 嗨,Guy E,

    我可以’t see 谷歌 saying, “Hey, we’不要再将PageRank的博客或目录中的链接计算在内,也不要对这些类型的链接大打折扣。”

    I do suspect that 谷歌 might devalue links from blogs or directories that they think might exist primarily for purposes of boosting PageRank, like blogs that might have been purchased to be included in private blog networks, and I’最近,在一些论坛上看到了很多讨论,这些论坛讨论的主题是一些众所周知的私人博客网络正在发生的主题。

    谷歌可能还会降低博客评论或他们认为是垃圾评论的评论所传递的PageRank的数量。而不是依赖rel =”nofollow”在博客评论中,他们可能已经放弃了这一点,并决定了以另一种方式衡量评论链接的价值,或者不给他们以重量。鉴于关于以下内容的论坛帖子和博客帖子数量似乎有所增加“do follow”网站,我可以看到Google考虑到这一点,而且我还可以看到许多博客作者关闭了“dofollow”他们可能正在使用的插件,以阻止垃圾评论发送者。

    还有很多目录似乎更着重于提高其中包含的网站的排名,而不是帮助可能使用其目录的人查找他们所寻找的信息。那’没什么新意,但也许Google决定他们尝试使用这些新手法。它’s also possible that many directories may also have made internal changes of their own to Nofollow listings, or send them through redirects that don’t传递任何PageRank值。

    谷歌 discontinued their own “directory” not too long ago, which was pretty much DMOZ but with the listings organized in a manner determined 通过 谷歌. Maybe they have devalued 目录 listings as a whole.

    I would suspect that if you think 谷歌 might be passing along less weight for links from blogs and directories that you’ve possibly explored if those changes seemed to come from those sites themselves rather than because of something that 谷歌 might have done.

  75. 令人难以置信的工作。感谢您的伟大想法。

    In my opinion, I think more of personalized page rank or depending search terms (universal search) where 谷歌 could focus on image, videos or text. Social “pings” importance will probably also increase. 那’只是时间问题。

  76. It makes sense that 谷歌 would diminish the value of links between affiliated sites that are not “编辑确定”。我想知道,网站管理员/ SEO员工创建自己的网站中心以支持他们或他们的客户有多普遍?’ linking profile.

  77. 我认为这可能是锚文本,因为Google宣布它将在未来对反向链接的影响较小,并且已经对其进行了修改以防止类似Google炸弹这样的事情。除了谷歌,谁真的知道?他们’真是个谜,我想他们想坚持下去。

  78. 感谢您的这些想法,比尔。还有更多其他规则,但是您的列表包含最重要的规则,在最近两年中多次更改。

  79. 嗨杰森,

    谢谢。

    Is it possible that 谷歌 is using a different approach than the one described above involving personalized PageRank. I’m not fully convinced that approach is one that 谷歌 has been using. It is possible that social activities on 谷歌 Plus could also play an increased role in personalization as well.

  80. 嗨乔尔,

    I agree 关于 lessening the value of links between sites that are affiliated 通过 things like common ownership, and I suspect that is something that 谷歌 has been doing. 我不’t think 谷歌 would have stopped that, and I can’想不到他们可能会使用的另一种方法。我确实认为某些网站所有者确实创建和/或使用了您提到的各种枢纽。

  81. 嗨丽贝卡,

    I’m not sure that I’ve seen a clear statement from 谷歌 that anchor text would have less influence in the future, but something like 基于短语的索引 can lessen the impact of anchor text that might not be very relevant or appropriate, and provides a way to stop 谷歌 Bombs as well.

    I agree with you that 谷歌 wants as much of what they do to be as much of a mystery as possible.

  82. 嗨,爱德华,

    您’重新欢迎。不确定我有多少种分析方法’ve listed have changed, and I know there are a number of others as well. 谷歌 provided enough information with their post to make this a mystery, and not enough to give us a clear idea of what they might have changed. Is it tied to the devaluation of link networks, since that seems to be something 谷歌 appears to have done a lot of recently? Maybe.

  83. From a strategic perspective, 谷歌 has moved into dangerous ground 通过 devaluing third party links. Granted this has been a gradual process over the past several years.

    谷歌’的主要价值添加为搜索引擎– it’最有防御性的立场–只是“rolling up the data” 关于 what the denizens of the web thought was important / useful. One metric of this is links (one link = one 投票), search behavior (what clicks, sticks, bounces) was another key indicator. Both are independant, fairly objective, and relatively hard to fake. 谷歌 wasn’t directly “ranking”内容质量–仅报告用户/网站管理员的想法。

    什么are the alternatives?

    – Social Media? 谷歌’在那里,社交媒体的嗡嗡声也相对容易被伪造。
    –语义分析

    后者是一个非常可怕的地方– if 谷歌’s “automated review” of what it 认为 a good website should have becomes the basis of determining search rank. Both for webmasters and 谷歌. Imagine a political candidate whose website ranked on the second page – because they didn’t follow 谷歌’s rules… or a 谷歌 competitor in a similar situation? Once 谷歌 starts directly rendering an opinion 关于 what is good / bad, the objectivity of their search results comes into question…

  84. 嗨,约翰,

    我们正在进入一些不确定的领域,Google会考虑更多的信号,包括一些可能是社会性的信号,以及其他可能更多地依赖语义分析的信号。此外,Google一直在扩展他们对什么的定义“relevance”表示从查询中的关键字到文档上的关键字的简单匹配。谷歌’试图了解许多查询背后的情境或信息需求,以及它们可能最匹配的概念和类别。它’也可能更多的用户行为数据在什么位置上起作用,或者是试图最好地预测用户行为的统计模型的基础。

  85. 嗨西蒙妮,

    When I wrote this post, my motivation was to show that 谷歌 uses a lot of different link analysis methods, and has described a good many of them in patents or papers. 我不’t know if any of the 12 I listed were the one that 谷歌 stopped using. I probably could have listed over 100 if I had a week or two to do it. 🙂

  87. 谷歌 is creating a great confusion on our part due to changes in its search algorithm. Some web administrators even received e-mail notifications from 谷歌 warning them 关于 不自然的 links on their site. Yet the manner 通过 which 谷歌 determines “unnatural” is still a big question. 谷歌 advises us to create quality content, but can hardly protect us from possibility of poor links being directed to our site 通过 our competitors.
