The impact of DIV CSS web page layout on search engine optimization SEO:
Search engine optimization SEO mainly makes it easier for search engines such as Google and Baidu to search the website by optimizing the structure, tags, layout and other aspects of the website. content, and allow each web page of the website to obtain higher scores in search engines such as GOOGLE, thereby obtaining better rankings. The following introduces the impact of DIV CSS web page layout on SEO.
1. Nesting 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. Dot has not been officially confirmed by the search engine. The results of several of my experiments are not fully available, but according to the current situation, spiders crawl tables with table layouts. When encountering multiple levels of nested tables, they 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.
The DIV CSS 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-layer table nesting when designing. SEOers have explained this in their articles, and I believe they are not without basis. .
2. Code simplification
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, because it can crawl efficiently, it will be affected by spiders. I like it, this will be beneficial to the number of collections.
3. Speed ​​issue
DIV CSS layout reduces page code compared to Table layout, and the loading speed is greatly improved, which is very beneficial when crawling by spiders. Too much page code may cause crawling timeout, and spiders will think that the page is 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. Impact on rankings
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 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 point may be controversial, but Sishu himself maintains this view. Those who have objections can compare and observe more than three groups of websites with basically the same quality.
I think this situation may not be a ranking rule. The most likely reason is that when spiders crawl the website, the above differences lead to different inclusion quality.
After all, nothing is better than nothing. It is recommended that friends who build or revise websites should choose DIV CSS layout if the technology permits.
