Advantages of using DIV CSS web page layout in SEO optimization_html/css_WEB-ITnose

SEO is mainly about optimizing the structure, tags, layout and other aspects of the website to make it easier for search engines such as Google to search the content of the website, and to make each web page of the website more searchable on Google and other search engines. Get higher ratings and thus get better rankings. What impact does DIV CSS web page layout have on SEO?

1. Streamline web page code

Using DIV CSS layout, the page code is streamlined. I believe everyone who knows XHTML knows this.

There are two direct benefits brought by code streamlining: First, it improves Spider crawling efficiency and can crawl the entire page in the shortest time, which has certain benefits for the collection quality; second, it can efficiently If you crawl, you will be liked by spiders, which will have certain benefits for the number of inclusions.

2. Solve the nesting problem of tables

Many articles on how to promote websites say that search engines generally do not crawl tables with more than three levels of nesting. This has not been understood. Search engine official confirmation. The results of several of my experiments are not fully available, but according to the current situation, Spider crawls Table layout pages, and when encountering multiple levels of nested tables, it will skip the nested content or directly abandon the entire page.

Using Table layout, in order to achieve a certain visual effect, multiple tables have to be applied. If the nested table contains core content, and Spider skips this section when crawling and does not capture the core of the page, the page becomes a similar page. Too many similar pages in a website will 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 much nesting when controlling styles.

Although this has not been confirmed, it is still recommended that friends who use Table layout should try not to use multi-level table nesting when designing. SEOers have explained this in the article, and I believe they are not. There is no basis for it.

3. Improve access speed

DIV CSS layout reduces page code compared to Table layout, and the loading speed is greatly improved, which is very beneficial when crawling by Spider. Too much page code may cause crawling timeout, and Spider will consider the page inaccessible, affecting inclusion and weight.

On the other hand, real SEOers are not just pursuing inclusion and ranking. Fast response speed is the basis for improving user experience, which is very beneficial to the entire search engine optimization and marketing.

4. Ranking of search engines

The DIV CSS layout based on the XTHML standard will generally be as complete as possible after the design is completed to pass W3C verification. So far, no search engine has stated that the ranking rules will favor websites or pages that comply with W3C standards, but it turns out that websites using XTHML architecture generally have good rankings. This may be controversial, but Sishu himself maintains this view. Anyone with objections can compare and observe more than three groups of websites with basically the same quality. Examples of websites that use DIV CSS page layout: Pipiflash www.pipiflash.com

I think this situation may not be a ranking rule. The most likely reason is that when spiders crawl the website, the above differences will lead to the inclusion quality. different.

After all, nothing is better than nothing. It is recommended that friends who build or revise a website should choose DIV CSS layout if the technology permits.
