Good quality writing web code is helpful to search engine

The simplicity and logic of the coding of the Web page is also an important index to evaluate the work of search engine optimization.

First, follow the Web standards
It is recommended that web designers follow the standards recommended by the Internet Standards Organization to write web code, rather than continue to use the traditional table layout method to make Web pages.
Web standards are collections of specifications that are developed by the Consortium and other standardization organizations to create and interpret the basic content of a Web page. These specifications are designed specifically for backward-compatible documents posted online to make them accessible to most people.
By following Web standards to write Web pages, you can benefit from:
Easier development and maintenance using more semantic and structured HTML makes it easier and faster to understand code written by others.
Compatible with future browsers using defined standard and canonical code, backward-compatible text eliminates the prospect of future browser recognition.
Faster Web downloads, less reading HTML code will bring smaller files and faster download speeds. Today's browsers are in standard mode with faster page reads than they did in the previous compatibility mode.
Better accessibility semantic HTML (separation of structure and performance) makes it easy for readers who use browsers and different browsing devices to see content.
The separation of content and performance from higher search engine rankings makes content a subject of text. The combination of semantic markup will improve your ranking in search engines.
Better adaptability a semantic-labeled document can be well adapted to print and other display devices (such as PDAs and smartphones), all of which can be done simply by linking different CSS files. It is also possible to perform a cross-site conversion by simply editing a single file.
Web standards can save time and money for Web site creators and provide a better experience for visitors to the site. If you want to learn more about web standards, recommend visiting sites:www.w3cn.org。
Second, the logic of the Code
Search engine is through the analysis of Web page source code to analyze the logic of the page text information, so when writing web code must be used as far as possible to use the appropriate label to reflect the level of text expression, that is, let search engines "understand" which text information to be heavier than other parts.
1. Title Label
In the HTML code, the caption has 6 labels, and their specific code representation is: "There may be many headings in an article, such as the main body headings, subheadings, paragraph headings, and so on. We should assign the appropriate title tag according to the logical importance of the title, the headline should be <H1&GT, the subtitle is 2. Emphasis label
To illustrate the importance of certain words or sentences in the body of an article, we should identify them by the HTML accent code so that they distinguish them from the words or sentences of other parts.
General emphasis tag: <em>,html code manifestation: "<em> accent words or sentences </em>", the word or sentence included in the <em> tag is displayed as italic in the Web page.
Emphasis on labeling:<b> and &LT;STRONG&GT;, specific HTML code representations: "<b> accent words or sentences </b>" and "<strong> stressed words or sentences </strong > ", highlighted by the emphasis tag includes words or sentences that appear bold in the Web page. <b> mainly focuses on the visual emphasis, while <strong> refers to the semantic emphasis.
The above two kinds of label expression of the text logical weight is very large, so its coordination of the expression of words in the search engine text analysis occupies a great advantage, it is not difficult to understand why a lot of SEO attention to them. Web Designer in the construction process of the site should try to use a rich variety of labels, so that the text of the Web page logic, so that the search engine can better read "understand" the information in the page. For search engine optimizer, it is a good choice to deploy keywords in these tags.
