Div+css layout of the site to the website SEO Impact Analysis _ Experience Exchange

Conforming to the XHTML standard DIV+CSS layout of the site, the following talk about the impact of SEO.

Code Refinement

With the Div+css layout, the page code is streamlined, which is believed to know something about XHTML. The direct benefits of code simplification are two points: one is to improve spider crawling efficiency, in the shortest possible time to complete the entire page, so that the quality of the inclusion of certain benefits; The second is because it can be efficient crawling, will be the spider like, so that the number has a certain advantage.

Nested problems with Tables

Many seoer in their articles, the search engine generally do not crawl more than three layers of table nesting, which has not been confirmed by the search engine official. Several of my experiments didn't come out completely, but according to the current situation, spiders crawl table Layout page, when encountering multi-level table nesting, will skip nested content or directly discard the entire page.

Using the table layout, to achieve a certain visual effect, you have to apply multiple tables. If the nested table is the core, the spider crawls over the core of the page without grabbing it, and the page becomes a similar page. Too many similar pages in the site can affect rankings and domain trust.

The div+css layout basically does not have such a problem, from a technical point of view, XHTML does not require too many nesting in the control style.

This is not confirmed, but it is recommended to use the table layout of friends, in the design as far as possible do not use multi-layered table nesting, seoer in the article explains this, I believe they are not without basis.

Speed issues

The Div+css layout reduces the page code compared to the table layout, and the loading speed is greatly improved, which is very advantageous when spiders crawl. Excessive page code may cause crawling timeout, spider will think this page is inaccessible, affect the inclusion and weight.

On the other hand, the real seoer not only for the pursuit of inclusion, ranking, rapid response speed is to improve the user experience of the foundation, which is very beneficial to the whole search engine optimization and marketing.

Impact on rankings

Based on the XTHML standard div+css layout, generally after the completion of the design will be as complete as possible to pass the certification. As of now, no search engine has indicated that ranking rules tend to conform to the Web site or page, but it turns out that websites that use the XTHML architecture are generally well ranked. This may be controversial, and dissent can be compared with more than three groups of basic equivalent quality of the site comparison observation.

I think this situation may not be the ranking rule, the largest possible or spider crawling site, the above differences lead to the quality of the inclusion of different. Suggest build station or revision of friends, technology licensing case, or choose Div+css layout as well.
