Because of the original book Zac, the author deliberately concerned about the Zac blog, after observation, the author said that the pear is very big: the original oneself still have a lot of need to learn, some originally thought oneself understand, originally can understand more, some originally did not understand, now finally understand. Do not understand do not admire Zac innate language talent.

Get to the point, from Baidu Official SEO optimization Guide We can know that the tree structure has been recognized by search engines, and become the mainstream.

Tree structure, that is, the root directory into multiple channels, or categories, directories, and so on, whatever the name is, is a meaning, and then put on each channel below the channel's Web page. For example, the channel is divided into:

http://www.domain.com/cat1/

http://www.domain.com/cat2/

http://www.domain.com/cat3/

......

Put the specific content page under the channel:

Http://www.domain.com/cat1/pageA.html

Http://www.domain.com/cat1/pageB.html

Http://www.domain.com/cat1/pageC.html

The second meaning of the structure of a Web site refers to the logical structure or link structure, which is a logical or linked network Diagram formed by a link within a Web page.

The better case is that the logical structure is consistent with the tree-type physical structure in front of it:

Homepage link to all channels home

The home page is generally not directly linked to the content page, unless you are very interested in pushing a few special pages

All channel home pages are connected to other channels

The Channel home page is connected back to the website

The channel homepage is also connected to a content page that belongs to its own channel

The Channel home page is generally not attached to a content page that belongs to another channel

All content pages are connected to the Web site home page

All content pages are connected to their top level channel home page

Content pages can be connected to other content pages of the same channel (note: Now many CMS this function is not perfect, it is recommended to be recognized by the CMS system, such as Dede. )

Content pages are generally not connected to the content pages of other channels (because the same channel is the most relevant, of course, it is best to link the same channel)

Content pages In some cases, you can connect to the content pages of other channels with the appropriate keywords

Channel Formation theme

Read the preceding sentences carefully, and you can clearly see that these links will naturally form a tree-like network Diagram, and this logical or linked network can coincide with the physical structure, or it can be different. For example, flat-type physical structure Web sites can also be linked to form a logical tree structure.

What is more important to search engines is the logical structure formed by links.

Many people have misunderstood that the physical structure of the Web page is not easy to be indexed by search engines. For example

Http://www.domain.com/cat1/cat1-1/cat1-1-1/pageA.html

Like such a deep directory structure of the Web page, is not easy to be included? That's not necessarily true, if this page has a link on the homepage of the website, it is only a level two page after the homepage for the search engine.

The easy or not to be included is the distance from the home page several clicks, not its physical location.

For a slightly larger site, the general tree-type logical structure of the site is relatively good.
