The traditional web site structure faces new challenges?

In the traditional SEO theory, the planning of a reasonable site structure should be at least three levels, that is, the home page, classification or catalog page and the final content page (of course, depending on the size of the site, the middle page may be layered, for simplicity, this article for example, three-storey structure, Also does not involve the combination of tag and other planning matrix Web site structure of the topic, in order to maximize the search engine indexed pages and the final page ranking between the smooth: In general, almost all the pages have links to level two pages, let PageRank smoothly along the homepage <=> category page <=> The final content page way to ensure that each page gets the corresponding PageRank, at the same time, by ensuring that these two-level pages have enough PageRank, in turn improve the content page by search engines indexed and indexed speed.

However, from a basic SEO goal, the hope is that content pages and the home page will be ranked first for specific search terms, as for the middle level of classification or table of contents page, it is not the main object of concern, so that its ranking in the former does not have much significance, and sometimes even visible for the search engine optimization process generated in the "noise." The simple question is, is it a waste to let a lot of PageRank flow to these level two pages? Or, if the PageRank of the home page is not being diverted by these two-level pages, all pass to the content page (of course, the PageRank from the content page to the home page will often be a piece of these level two pages), will not let the content face in the search engine more competitive?

However, in the previous search engine optimization, in any case, to ensure that the site pages in a comprehensive, fast search engine indexed, index is the first task, therefore, this problem, even if there is not seoers can solve the problem, or, is the cost of the process of SEO has to be made. But now? Especially for Google, indexed web pages, regardless of speed or breadth, there has been a revolutionary breakthrough, although the so-called "Google is Inc. to update its index in the minutes" is a bit exaggerated, but also to some extent, the trend is explained, In fact, most of the new pages of today's pages are almost all in a very short period of time by Google Index, that is not a problem. On the other hand, the included pages have had to go into the supplemental index because they have not been pagerank enough to do so--although Google is no longer tagging the supplemental results on the SERP page--causing the page to not get the expected ranking at all, but If PageRank is not being diverted by level two pages, these pages are likely to enter the Google Master index.

Does this mean that the traditional web site structure, or the internal link mode that PageRank transmission and flow, requires some degree of adjustment?

Note: Again, the focus of this article is on the final ranking of the page, not the index and inclusion of the page. If your site is included in the problem, the content of this article is absolutely inappropriate for you.

Matt Cutts recently responded to Randfish's question about "nofollow":

the following references:


...... There ' s no stigma to using nofollow, Evan on your own links; For Google, Nofollow ' ed links are dropped out of our link graph; We don ' t Evan use such links for discovery ...


One of the randfish's explanations for this passage is:

the following references:


webmasters can feel free to use nofollow internally to help tell Googlebot abound pages tightly want to receive link 2.4bn from oth ER pages

Of course, from a simple point of view, perhaps Matt Cutts really wants to say that for web pages that have little meaning to search users--for example, almost every page in the site has links to "about us," "Contact us," and so on, Perhaps it is a wise choice not to waste PageRank on them, but if you follow this way, you will find a lot of interesting questions, especially for the level two page of the three-tier Web site structure, let it get too high PageRank is not also can say is a kind of meaningless waste? For example, do not let PageRank in level two pages (the directory page of the cross link) needlessly lost, and mandatory level two page PageRank all passed to level three page will be better? Another example is to let the level three page PageRank no longer pass to all the classification pages will be better, the homepage and related content pages more competitive? Wait a minute.

Of course, this is not to say that the level two page should not be PageRank, but that, in order to ensure that it gets enough PageRank the premise of avoiding its "swallowed" too much waste, The traditional Web page architecture in almost every page of the site to contribute to the two-level network PageRank way seems to need some degree of change.
