Do they treat links and collections of links that they find on more than one page of a site differently than links and collections of links only on one page? If they find more than one group of links on a page that contain many of the same links, though at the top and bottom of the page, how 威力 they treat those links?
在2002年的论文中， SmartView：增强型移动设备文档查看器 (pdf), a couple of Microsoft researchers discussed how web pages 威力 be analyzed and partitioned into smaller logical sections to be viewed on small devices, such as handheld phones. These smaller sections could be selected 通过 a viewer and seen independently from the rest of a web page. One of the authors of that paper is listed as an inventor of the Microsoft patent, and the paper is cited within the 链接结构 patent as an example of how web pages 威力 be segmented in a way that benefits the viewers of a page.
专利申请中提到的另一个网页细分过程是称为Microsoft的过程 VIPS：一种基于视觉的页面分割算法. The paper describing this process was published in 2003 and explores a way of looking at the HTML of a page, along with a visual inspection of white space, horizontal rules, and other visual aspects of a web page that 威力 indicate that a page is broken down into different logical sections.
微软的另一篇论文’t mentioned in the patent filing, but which seems relevant, is one that explores how links from different blocks on a page 威力 be treated differently based upon where they are located on that page. The paper is 块级链接分析，其中还介绍了块级PageRank的概念：
那篇论文和微软的其他论文做了什么’t explore in much depth is how different blocks of links 威力 be related to each other. They don’t try to explore in any depth how links on a site 威力 be related to one another, and how the pages of a site 威力 be organized based upon links between the pages of a site. Looking at link blocks on a site, classifying them, and organizing them may yield some useful benefits.
Once a page is broken down into different segments, such as headers and footers, sidebars, main navigation bars, main content 地区, advertisement blocks, etc., the relationship between links in those segments across the site 威力 be explored.
To classify links and link blocks, a search engine would start 通过 analyzing the layout of individual pages to identify candidate link blocks and see where they occur on pages, and how they 威力 relate to each other. This 链接结构 analysis is used to create what the patent refers to as a Link Structure Graph or LSG.
那里 are three main purposes for creating an LSG:
除了导航链接之外，网站还可以包含结构元素中的页面链接，例如指向链接的列表。“best sellers”在电子商务网站上，或“most popular posts,” on a blog.
Some link blocks may appear more than once on the same page in different segments, with minor variations, and they may be merged together. For instance, the same or a substantially similar link menu 威力 be shown at the top and bottom of a page in the main navigation area and a footer navigation area.
在基本相似的链接块可能已经合并在一起之后，剩下的被认为是链接块“unique” are classified. Classification is based upon the function of a link block, and 威力 be described as being one of the following three types:
智能节点 –这些是孤立的链接，它们是页面上没有’链接组的一部分，由于它们在文本的同一段中一起出现，它们之间可能只是松散相关。页面上出现的每个链接’t classified as s-nodes or c-nodes 威力 be seen as a single collection of links and given an i-node classification. Each link on a page 威力 be considered an individual i-node, or they 威力 be grouped together 通过 page as an i-node.
If you were to look at a number of pages on different web sites, you 威力 not find it too hard to do this kind of classification for the links on those pages.
那里 are a number of reasons for the classification of links on a site. The paper on 块级链接分析 mentioned above tells us that links in different blocks 威力 be given different 重量s for ranking purposes. Understanding the 链接结构 of a site can also help when different parts of a site 威力 also be displayed on a handheld device with a smaller screen. But there are also other potential benefits that are described in the patent filing:
1) 链接 to other pages that 威力 be related to a page shown may be more easily uncovered. This patent doesn’t mention the use of quick links, but it does tell us that it 威力 present information about pages that are related and make it easier to navigate to those pages on a site. These 威力 be used with a personalization approach to uncover pages that 威力 interest a specific visitor, or be based upon an approach that increases a visitor’s ability to navigate to pages that 威力 not be directly linked to pages offered 通过 search results.
2) Internal linking information collected 通过 the search engine 威力 be offered to the site owners to allow them to optimize their use of links and to see statistics about visits between pages of a site.
3) The linking information 威力 be useful in the automatic tagging of web pages on a site.
For example, a page about Cars 威力 include category pages about specific brands of cars, then subcategories about specific models, and the specific product pages about car parts. Understanding the 链接结构 of a site can mean that the higher level link text of parent pages 威力 be used to help tag the lower level pages. So if a category page is pointed to with the anchor text “Ford”并且它有一个与锚文本链接的子类别“mustang parts,” which points to a page about a specific product page for brake pads, the brake pad page 威力 be automatically tagged with the terms “ford,” and “mustang parts.”
4) Like the automatic tagging above, internal links and anchor text between pages 威力 also be used to create a concept hierarchy for a site, which can then be compared to other sites containing similar concepts.
Using my car part site example, from the previous section on automatic tagging of pages, a hierarchy of concepts 威力 be created about a site offering car parts. That site 威力 be compared to other sites that may use similar terminology and which could even have a similar concept hierarchy. Those sites 威力 then be clustered together 通过 a search engine.
5) Anchor text in links found on a site 威力 be presented to viewers to help them navigate through the pages of a site in a sidebar, or in a kind of sitemap reflecting the 链接结构 of the site.

I’ve provided a high-level overview of a process described in the patent filing on how a search engine 威力 use a segmentation process to identify link blocks on a site, possibly merge some of those blocks together, and then classify the link blocks that they’ve found. The patent goes into more details on what it 威力 look for in creating those blocks, and merging them together, and then in classifying them.
该专利还提供了将链接分段和分类为链接块的一些可能的好处，但它可能还有其他一些好处’t detail, such as if the search engine 威力 give different link-based ranking values to links found in different kinds of link blocks.
The patent also describes how it 威力 include data collected about the links on a site from monitoring the use of those links from visitors to pages, though it doesn’不会深入探讨该方法背后的过程。
在我的上一篇文章中， 创建一个SEO库存，其中有一个专栏“Navigation Location”您可以在其中列出指向同一网站上其他页面的特定页面的链接的种类和位置，例如徽标链接或主导航链接。您可能需要考虑在类似于本Microsoft专利申请中所描述的框架的框架中列出的页面的链接，这些链接来自它们可能适合的分类。
