The impact of Div CSS web page layout on SEO
1. Streamline web page code
Using DIVCSS 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, because it can crawl efficiently, it It will be welcomed by spiders, which will be of great benefit to the number of inclusions.
2. Solve the nesting problem of tables
Many articles on "how to promote a website" state that search engines generally do not crawl tables with more than three levels of nesting. This has not been recognized by search engines. 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.
DIVCSS layout basically does not have such problems. 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 their articles, and I believe they are not without basis.
3. Improve access speed
DIVCSS layout reduces page code compared to Table layout, and the loading speed is greatly improved, which is very beneficial when Spider crawls. 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
DIVCSS layout based on 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 its ranking rules will favor websites or pages that comply with W3C standards, but it turns out that websites using XTHML architecture generally rank well. This may be controversial, but from my point of view, it is very beneficial.
