The obvious difference between div+css and table layout

Div+css layout less page code than table layout, loading speed is greatly improved, which is very advantageous when crawling spider.

The site layout is converted from the previous table to the current div+css layout. So how does this approach affect the site compared to previous table layouts? This article is to make a brief introduction
is mainly embodied in the following several aspects
One, the solution table nesting let spider bead tentacles countless small
Many of the "website How to promote" article said that search engines generally do not crawl three layers to C official confirmation. The results of my experiments are not completely out, but according to the current grasp of the situation, spider crawl table layout of the page, encountered multiple layers of table nesting, will skip nested content or directly discard the entire page.
Using table layout, you have to apply multiple tables in order to achieve a certain visual effect. If the nested table is the core content, spider crawl when the section is not crawled to the core of the page, this page becomes a similar page. Too many similar pages in the site will affect the ranking and Domain name Trust degree.
and Div+css layout basically does not have such a problem, from the technical point of view, XHTML control style does not need too much nesting. This is not confirmed, but it is recommended to use the table layout of friends, in the design as far as possible not to use multi-layer table nesting, seoer in the article to explain this, I believe they are not without basis.
Second, the streamlined code to make spider beads more comfortable to climb
Using the Div+css layout, the page code is streamlined, which is believed to be known to the XHTML.
The direct benefits of code streamlining are two points: one is to improve the spider crawl efficiency, in the shortest possible time to crawl through the entire page, so that the quality of the collection has some benefits; second, because can be efficient crawling, will be spider welcome, so the number has a great advantage.
Third, increase the speed let spider bead make time car
Div+css layout less page code than table layout, loading speed is greatly improved, which is very advantageous when crawling spider. Excessive page code may cause crawling timeout, Spider will think that this page can not be accessed, the impact of the collection and weight.
On the other hand, the real seoer is not just for the pursuit of inclusion, ranking, fast response speed is to improve the user experience degree of the basis, which for the entire search engine optimization and marketing are very favorable.
Four, the search engine ranking
Based on the XTHML standard div+css layout, generally after the completion of the design will be as perfect as possible through the universal authentication. There are no search engines to show that the rules will tend to conform to the standards of the Web site or page, but it turns out that using the XTHML architecture is generally a good position. This may be controversial, but from my point of view, it is very useful.
Of course, when you do div+css layout, you have to have code. Otherwise, it may be written in the Div no one else wrote the table good ~ ~ ~ ~
