On flat structure and vertical deepening structure of website

The company has a website very let me tangle, because that website structure is very complex, I put that website structure is called the longitudinal deepening structure. Today I and the company colleague programmer practice June chat about the topic of the website structure, many programmers understand the website flat structure of the design, but many programmers do not know flat web site structure in Baidu search engine principle. Including my colleagues to practice June also do not know the principle, so today I have light red on the website for the flat structure of the popular science!

Remember that year I was in Beijing just started 3u push the site, although I was only a founder team, but the entire 3u to the planning of the site is basically by me to operate, because I know that the establishment of flat Web site structure is a friendly attitude to Baidu search engine, Seoer all know that Baidu spiders crawl level when there is patience and budget, the standard is on the 3-4 floor.

"Home"-"section page"-"inner page" is our most common structure, this body only need three steps to complete the Baidu search engine to reach the content page and successfully crawled. This saves the Search engine crawl page time. The author once red show Baidu search engine in the crawl page when there are budget, for example: the original 3u web site structure is 5 levels, but I found from the space log Baidu Spiders can only crawl to 3 level, that is, spiders can not smoothly reach the fifth level crawl content. Then I put 3u to the structure of the site has been changed to two levels after the crawl is very fast. Of course, the search engine for those large sites of the budget level will be more, because the weight of large sites, so the content page to crawl more, included will be more!

such as "Plant"-"fruit"-"apple"-"banana"-"pear" I called it as a longitudinal deepening structure. I particularly dislike the structure of this site, Baidu search engine is also because it does not like this structure, for example: If the pear is Baidu search engine is the goal, but Baidu search engine must be slowly from a plant to climb down, and other search engines to climb bananas, the search engine may give you the budget has arrived, In other words, Baidu search engine can only crawl to the banana level two crawl not what you want (pears). Figure 1:

such as "Plant"-"fruit"-"apple"-"banana"-"pear", fruit is the first layer, "apple", "banana", "pear" and so on as the second layer, so it is easier to crawl to these pages. To make this idea more intuitive, see Figure 2:

I have red in the proposed programmer design site when the use of flat structure and pay attention to the number of links per page, a general standard of a page link number is not more than 100 links, if you have a page more than 100 pages, which is not like the search engine. Naturally also not much crawl your page, of course, such as Sina network, such as large sites except. Today is written here, again thanks to programmers to practice June technical exchanges!
