What are the benefits of DIV CSS layout website for SEO?_html/css_WEB-ITnose

DIV CSS is one of the commonly used terms in website standards (or "WEB standards"). It is usually used to explain the difference from the positioning method of tables in the HTML web design language, because in the XHTML website design standards, it is no longer Use table positioning technology, but use DIV CSS to achieve various positioning.

SEO refers to search engine optimization, which mainly makes it easier for search engines to crawl the content of the website by optimizing the structure, tags, layout, keywords and other aspects of the website, and makes each web page of the website waiting for search. Get a higher score in the engine and thus get a better ranking. DIV CSS web page layout has a very important impact on SEO. Specifically, what are the benefits?

The benefits of DIV CSS web page layout for SEO 1. There is no nesting problem of tables

Many articles on "How to promote a website" According to the report, search engines generally do not crawl tables with more than three levels of nesting. This has not been officially confirmed by search engines. 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 the 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.

Using DIVCSS layout, the page code is streamlined. I believe everyone who knows something about XHTML knows this. Watch more HTML tutorial content.

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, because If you can crawl efficiently, you will be welcomed by spiders, which will be of great benefit to the number of inclusions.

　
The DIV CSS layout basically does not have such a problem. From a technical point of view, XHTML does not require excessive 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 (seo workers) explained this in the article A little bit, there is no basis for believing them.

Compared with Table layout, DIV CSS layout reduces page code, and the loading speed is greatly improved, which is very important for spiders. (Spider) is very beneficial when crawling. Too much page code may cause crawling timeout, and spiders will think that the page is inaccessible, affecting inclusion and weight.
