How to optimize the website in HTML, I believe that many inexperienced people are at a loss about it. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Code specification for head area of website

The head area refers to the content between and.

Labels that must be added

1. Company copyright Notes

two。 Web page display character set

Simplified Chinese:

Traditional Chinese:

English:

3. Author and copyright Information

4. Css,javascript Specification of Web pages

Styles and scripts are best referenced in this way to improve the signal-to-noise ratio of the web page.

5. Page title

How to split in Title:

In English, the horizontal bar "-" is indeed a separator between some words.

Baidu and Tencent are all divided by underlining "_".

The maximum number of characters a search engine can use for an title index is 255 characters. However, generally speaking, the title characters displayed in Google and Baidu have a length limit:

Baidu: 60 bytes (30 Chinese characters).

If the length exceeds the limit displayed by the search engine, it will be replaced by an ellipsis.

If the title of a web page changes frequently, the search engine will think you are cheating.

6. Set search keywords

Baidu keyword search index: http://index.baidu.com/, in this tool, you can see the number of daily searches for some commonly used keywords.

Popular words, the most collected words at present. You can check Baidu's list of hot words, http://top.baidu.com/index2.html.

Google AdWords keyword tool: query common queries and extended matches for specific keywords.

The maximum length of the KEYWRODS keyword is no more than 5 suggested lengths: less than or equal to 100 Chinese characters. If the web page code used is UTF-8, different keywords are separated by English ",".

7. Introduction to the website

Description describes the content of a web page, so it is best to summarize the subject content of this page in one sentence.

Description should not exceed 255characters. Search engine indexes generally index the first 255characters of Description. Therefore, these 255characters are the key to search engine optimization.

If the web page code used is UTF-8, it is best to use English punctuation marks in Description, such as English commas, periods, etc. If it is Chinese, then you can use Chinese punctuation.

. You can choose to add tags.

1. Set the expiration time of the web page. Once the web page expires, it must be re-read on the server, which is beneficial to the page information.

Area label

Where the keyword is placed:

1. Keywords in the body of a web page

Keywords must appear appropriately in the text content, which plays a key role in the optimization of search engines. Generally speaking, 1% to 7% is more appropriate. Don't pile up all the keywords or key fields.

2. Add a "link" text to the content of the article

Add hyperlink text. That is to say, some words in the content of the article, such as Sino-British cooperative business management, can be linked to the corresponding brochure or class information, etc. Of course, it is best to use keywords as hypertext links.

3. Title

4. Make some important content into WEB slices (supported by IE8)

Incorrect writing: www.com-edu.cn

The correct way to write it is: www.com-edu.cn

7. Special characters are identified by coding

For example, "" is represented by ">".

8. Picture optimization in web page

Be sure to add the alt attribute, which specifies that the text to be replaced is displayed when the picture cannot be displayed. The content had better be related to key words.

Such as:

Some small icons are best to use .gif format images, such as arrows, icons in front of the article list, etc., to make a background in CSS.

These small icons had better make a picture and use CSS to locate it.
