XHTML Technical Issues Please refer to the relevant web site research, below to say in the SEO impact.

Code simplification

Using the div 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 a certain benefit; the second is because can be efficient crawling, will be spider like, so the number has a certain advantage.

Nested problems with Tables

Many seoer in its article said that search engines generally do not crawl more than three levels of table nesting, which has not been confirmed by search engine official. 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 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 a multi-layer table nesting, seoer in the article to explain this, I believe they are not without basis.

Speed problem

div 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.

Impact on rankings

Based on the XTHML Standard Div 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 I keep this in mind that dissidents can compare and observe three groups of sites with the same quality.

I think that such a situation may not be the ranking rules, the largest possible or spider crawling site, the above differences lead to the quality of the different included.

After all, Liao Sheng in the absence, the proposed site or the revision of friends, technology licensing circumstances, or choose div layout as well.
