DIV + CSS technology: the first choice for website revision and SEO Optimization

The tutorial for helping customers home (www.bkjia.com) Today's DIV + CSS technology has been developed and widely used. Many large websites basically use the new technology of DIV + CSS, because DIV + CSS is more friendly to the cable engine, it has a unique advantage in search ranking.

SEO refers to the optimization of search engines. It mainly optimizes the structure, tag, and layout of websites to make it easier for search engines to capture website content, in addition, the website's various web pages are rated higher in other search engines to obtain a better ranking. DIV + CSS webpage layout has a positive and meaningful impact on SEO.

Through the introduction of the two paragraphs, DIV + CSS + SEO will naturally walk in one piece. Let's talk about the three points below:

I. Simplified Web Page code

With DIVCSS layout, the page code is simplified. I believe I know all about XHTML.

The direct benefits of code streamlining are as follows: first, improving the crawling efficiency of search engine Spider and crawling a complete page in the shortest time, which has certain benefits to the indexing quality; second, Spider will be welcomed because of its high-efficiency crawling capability. This will greatly benefit the number of indexed items.

Ii. Solve the Problem of table nesting

In many articles about how to promote websites, search engines generally do not crawl nested tables on three or more layers. These 1.1 pieces are not officially confirmed by search engines. The results of my experiments are not complete, but according to the current situation, When Spider crawls the Table layout page and encounters multi-layer Table nesting, the nested content is skipped or the whole page is abandoned directly.

When using Table layout, you have to apply multiple tables to achieve a certain visual effect. If the nested table contains the core content, the Spider skips this section and does not capture the core of the page. This page becomes a similar page. Too many similar pages on the website will affect the ranking and domain name trust.

There is basically no such problem in DIVCSS layout. Technically speaking, XHTML does not require too many nesting when controlling styles.

Although this is not confirmed, we recommend that you do not use multi-layer Table nesting during design. This is explained in the article by SEOer, I believe they are not without justification.

3. Improve access speed

Compared with the Table layout, DIVCSS reduces Page code and greatly improves loading speed, which is very advantageous for Spider crawling. Too many page code may cause crawling timeout, And Spider will think that this page cannot be accessed, affecting the indexing and weight.

On the other hand, the real SEOer is not just for indexing and ranking, but the rapid response speed is the basis for improving the user experience, which is very beneficial to the entire Search Engine Optimization and marketing.

4. Ranking of search engines

Based on the XTHML standard DIVCSS layout, after the design is generally completed, it will be as perfect as possible to pass W3C verification. Up to now, no search engine indicates that the ranking rules will tend to comply with W3C standards for websites or pages, but it turns out that the ranking of websites using XTHML architecture is generally good. This may be controversial, but from my point of view, it is very helpful.

I think this may not be the ranking rule. The biggest possibility is that when spider crawls a website, the above differences may lead to different indexing quality.

It is recommended that you select DIV + CSS layout + SEO optimization with the technical license.
