This article will explain in detail about the impact of DIV+CSS design and development of Xhtml pages on SEO optimization, the editor thinks it is very practical, so share it for you to do a reference, I hope you can get something after reading this article.

First: the crawling efficiency of DIV+CSS pages for spider

Div+Css code streamlining is table can not match, even if DIV CSS html plus the corresponding CSS files are generally smaller than table html files, div+css to achieve a complete separation of style and layout, the foreground junk code is greatly reduced, the content is more prominent, so that spiders crawl quickly on your site, crawling your site in a short time.

Second: improve the speed of opening web pages

As we all know: the customer is God. Search engines are no exception, so search engines will give priority to crawling websites with better customer experience. The real SEOer is not only for the pursuit of inclusion, ranking, fast response speed is to improve the user experience of the basic site. Question: if it takes you more than a minute to open a website, will you come to this site next time?

The DIV+CSS layout reduces the page code compared with the 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 think that the page is inaccessible, affecting inclusion and weight.

Off-topic: tale layout page opening principle: general table layout page is a large table set of tables, in the table nesting small tables, small tables and then set small tables. Generally speaking, the first table (outermost) can only be displayed after reading. When reading a large table, you have to read a small table in a large table at the same time, which greatly increases the speed of opening the web page.

That is, when the browser loads the table page, it usually waits for loading and closing the table before sending the content to the viewer, which makes the viewer feel that the page and so on take longer and feel slow.

Third: the impact on search engine rankings

The DIV+CSS layout based on the XHTML standard is generally as perfect as possible after the design is completed so that it can be verified by W3C. So far, no search engine has indicated that the ranking rules tend to be W3C-compliant sites or pages, but it turns out that sites using XHTML architecture are generally in good shape. This may be controversial, but Xu Sichu himself maintains this view, and some dissidents can compare and observe more than three groups of websites of the same quality.

DIV+CSS has much more overall control over web pages. Through simple code modification, the code of the website can be greatly optimized and revised. It's very practical.

Many people feel that CSS is very beneficial to ranking, but there are many factors that affect the ranking. This is not the only one without a foundation can also use the table, but the table should not exceed three layers. It is suggested that friends who do not know css+div have time to study.

The downside of DIV+CSS:

1. It takes more development time to develop DIV+CSS pages than TABLE pages.

2. Compatibility, because it is in the period of browser war, and the kernel of each browser is different, which results in a little different interpretation of CSS attributes, which is a thorny problem for beginners. It is believed that the browser can unify its interpretation in accordance with the W3C standard.
