Analysis of the relationship between search engine optimization and Web design

A, div + CSS Web design for search engine optimization (SEO) advantages

because these are popular with DIV+CSS to make a page, unlike most domestic enterprises site TABLE is different, so I want to talk about DIV+CSS Web design to search engine optimization (SEO), what are the advantages? these are compared in the TABLE.

reduce page code div + CSS Layout Table layout, loading speed is greatly improved, and this is very beneficial when the spider crawling. Excessive page code can cause crawling timeout, spider may think that this page cannot be accessed, influence recording and weights.

1, code simplification

Use DIV + CSS layout, the page code to streamline, which I believe to know XHtml would know. Code streamlining benefits brought about directly by two points: first, to improve spider crawling efficiency, can in the shortest possible time after climbing the whole page, this collection offers some benefits; the second is due to the efficient crawl, spider like you will be, included in this number has certain benefits.

2, form nesting issues

said in many articles in website promotion, search engines generally do not capture more than three layers of nested tables, this has not been confirmed by the official search engine. Results of the experiments I did not completely out, but according to the present situation, spider crawl Table layout pages, nested tables when encountering more will skip the nested content or give up the whole page.

use the Table layout, in order to achieve certain visual effects, have to apply more than one form. If the nested table is the core content, spider crawling skip this paragraph did not crawl to the core of the page, this page is a similar page. Too many similar pages on the Web will affect the ranking and domain trust.

div + CSS layout, there is virtually no such problems from a technical standpoint, XHTML in control styles and do not need too much nesting.

Although this has not been confirmed, but it is recommended to use Table layout for friends, at design time as much as possible do not use multiple layers of nested tables, SEOer illustrates this point in the article, I believe that they are not based on the.

3, speed

reduce page code div + CSS Layout Table layout, loading speed is greatly improved, and this is very beneficial when the spider crawling. Excessive page code can cause crawling timeout, spider may think that this page cannot be accessed, influence recording and weights.

the other hand, real SEOer not included in pursuit, ranking, fast speed of response is the basis of improving the user experience, which is very beneficial for the whole search engine optimization and marketing.

4, impact on the rankings

div + CSS layout based on XTHML, upon completion of the design will be as perfect as possible to pass W3C validation. So far there is no search engine ranking rules tend to meet W3C standards for Web site or page, but it turns out using XTHML architecture websites rankings are generally good. This may be controversial, but Park SI Shu-I keep the view, dissidents can take three or more basic site comparison of equal quality.

I think that this situation might not be ranking rules when most likely or spider crawling the site, appear above differences included the quality difference.

Liao Sheng, after all, free, suggested or revision of friends, technology licensing case, might as well select the div + CSS layout.

Second, affect the SEO search engine optimization Web design details

1, CSS and jAVACSRIPT all use the method below to external files, and HTML code is used to display the actual content of the maximum possible.

2, the use of Xhtml code pages, abandoning the traditional Table layout mode, remove the page format such as font/bgcolor control in the label. Using Web standards-compliant code to make pages. It can make structured, semantic XHTML code. Improve page readability of the code.

3, used the method above you will find the HTML code can be very small, of course, if you can. Make it smaller. Too much will affect processing speed of the engine. Through the XHTML+CSS Web page, HTML code can be contained within 50K. You can take a look in Web standards well reconstruction sites.

4 the use of ALT tags is reasonable, good a picture page keywords to describe the picture, this will increase the keyword density of the page.

5, minimal use of JavaScript to do content-related things, such as using document.write to show text. It will affect the search engine search for page content.

6, do not go to the JavaScript to make your navigation of the site, that the search engine would have lost.

7, the keywords of each page appear in the title of the page as possible, which is in the Title tag of the head. Of course, rational use, and too long, but don't use a lot of network of popular keywords regardless of the page content. Because it is not optimal but cheating.

8, as far as possible in each of the fair use tags in the page code, and keywords to appear in a label, so page document structure more clearly
