In addition to garbage stations, very few sites are only composed of a single page, when it comes to multiple especially thousands of pages, often need to have a clear web site structure to ensure that the search engine and user access, the site's directory structure plays such a role, it in the significance of the SEO.

1, what is the directory structure of the site

The directory of the Web site is the directory you created when you set up the site, the directory structure is mainly refers to the physical structure and logical structure of these two.

Specifically, the physical structure of the site refers to the structure of the site directory and the real location of the contained files. For small Web sites, all pages have a flat structure under the root of the site, and the flat structure of this single directory is ideal for search engines, as only one visit can be traversed. But if too many files are in the root directory, maintenance is quite troublesome, and for larger sites, often need two to three or more levels of subdirectories to ensure the normal storage of file content pages, this multi-level directory is also called the tree structure, that is, the root directory subdivided into multiple channels or directories, Then store the ultimate content page of this directory under each directory, which is easy to maintain, but search engine crawling will be difficult.

Different from the physical structure of the website, the logical structure of the website is also called the link structure, which refers to the logical structure formed by the internal link of the Web page or the structure called link. This is now part of the CMS station system can be implemented in the file although there are different physical structure of the directory, but access to the directory level of the link only need one layer can be turned to access.

2, the site's directory structure on the impact of SEO

The level of the directory structure of the site has a great impact on SEO. The directory level of the site is not too deep, the simpler the directory structure, the easier search engine access, the deeper the hierarchy of directory structure, search engine crawler is not easy to crawl.

This is a simple truth, someone said a wonderful analogy, for example, when you are anxious to go to the toilet, the total will not wear street walk around the circle, and always give priority to the nearest toilet. For example, "The bouquet is also afraid of the alley deep", and then a good content page, if hidden in too deep directory level, search engines are to exclaiming, and sigh alas!

3, how to optimize the structure of the site

The structure of the directory is often easily overlooked by the general web site, in fact, the quality of the directory structure, the site's SEO has an important impact. The internal structure optimization of the website is also an important link in the whole optimization process. So, as SEO, how to optimize the structure of the site? I think the optimization of the site structure should mainly involve both physical and logical structures.

First, optimize the site's physical structure directory. Generally speaking, we do not advocate to keep all the files in the root directory, and encourage the creation of subdirectories by column content, and try to use meaningful directory names, such as Image,css,js,post,bbs and so on, but do not use the Chinese name, Especially for English SEO optimization should use Chinese directory, directory name should not be too lengthy, the URL should be shorter the better. For example, we do not need to change the directory of SEO to Sousuoyinqingyouhua, because the search engine can understand the word SEO. Directory and file naming can be used properly to the keyword, if it is a key phrase, need to separate the words, we often use the hyphen "-" to separate.

Most importantly, the directory level of the site is generally not recommended to more than 3 levels!—— This is our SEO process on the site's physical structure directory the largest one optimization. This optimization, if not regardless of SEO, there are many other benefits, such as less level of directory easy to spread, user experience and exchange links and so on.

Of course, this is not absolute. No matter how deep the directory level is in a content page, as long as the page has one or more external links from other sites, it will also be included in the search engine, if we add a link to the page, then in fact, the equivalent of two clicks can access to the page, and then deep Alley if a train, the same will be customers , so the link is the key to be indexed by search engines. For a subdirectory contained in a site, all search engines provide traversal of subdirectories, provided that the link to the subdirectory of the layer provides a navigation configuration and URL structure that the search engine can follow up on. Do a good job of navigation structure, will effectively control the multi-level directory structure of the adverse impact of SEO.

Secondly, the logical structure of the site should be the same emphasis on the optimization. Generally speaking, the first page of the PR value of the highest, level two directory, the final content page again, so in order to make these pages more effective display, it is necessary to minimize the loss of PR, so the directory structure not too deep, three is enough, and all the links should be able to do each other loop The logical structure of the directory should also be as far as possible to meet the "breadcrumbs navigation" utility. So that the search engine just grab a page, you can follow this page to crawl more or even the entire site of all pages. In addition, to note that if the site adjustment, the page directory structure changes, the page was moved to a new address and other changes in the directory structure, we should fully consider the SEO, as far as possible using 301 redirect to the new page, so as to avoid the site dead chain, broken chain, wrong chain and so on.

4, the Site directory structure in the SEO rankings of the specific application methods

Lone heroes in front of, the site directory structure of the level of the impact of SEO, the simpler the directory structure, search engine access will be easier. For Baidu, it gives the site's domain name, directory and the weight of the page is not the same. When participating in the keyword ranking competition, the domain name level of the link in Baidu is the most advantageous, directory level second, page level is the lowest. So when we are concerned with the keywords, most of the top ten are page-level sites in competition, then we can create a directory under the site to participate in the competition; if the top 10 are directory-level, then we need to use the domain name level to fight for rankings, if the top 10 are domain name level, then you have to spell the weight and quality of the site.

Here, we also have to solve a question: class two domain name and level two directory, that is, the subdomain and subdirectory, the two in the end that directory structure is more easily included?

Generally speaking, the weight of level two directory increases, can increase the weight of the main domain name, the weight of the main domain is increased, can also drive the weight of level two directory. Second-level directory is dependent on the main domain name weight, the main domain name included intact, directly able to speed up the two directory collection, compared to the two domain name, two-class domain name in the search engine is quite independent of the site, single URL, two-level domain name than a level of natural trust is a little higher, but included in the list may be slightly slower than the two level directory.

If your site is not a lot of categories, it is recommended to use the form of level two directory, which is more conducive to the promotion of the flagship brand and enhance the weight of the site. If you are a more diverse category, the content of a more abundant site, it is recommended that you use the form of level two domain name.
