Website URL
Website creation has good descriptive, standard, and simple URLs, which helps users easily remember and judge the content of webpages, and also helps search engines capture your websites more effectively. At the beginning of the website design, there should be reasonable URL planning.

 
Processing Method: 1. In the system, only normal URLs are used, so that users are not allowed to access abnormal URLs. 2. Do not place unnecessary content such as session ID and statistical code in the URL. 3. For URLs of different forms, 301 is permanently redirected to the normal form. 4. Prevent the user from entering an incorrect backup domain name. 301 will be permanently redirected to the primary domain name. 5.use robots.txt to prohibit baiduspider from capturing a form that you do not want to present to users.
 

Title information
The title of a Web page is used to tell users what the main content of the web page is, and when users search for your web page in Baidu web page, the title is displayed in the abstract as the most important content.
When a search engine determines the weight of a webpage content, title is one of the main references.

 
Description suggestion: 1. homepage: website name or website name_provide service Introduction or product introduction. 2. Channel page: Channel name_website name. 3. Article Page: article title _ channel name_website name. Note: 1. The title should be clear and contain the most important content on this webpage. 2. Concise and refined, not listing information unrelated to the content of the webpage. 3. user browsing is usually left-to-right, and important content should be placed in the front of the title. 4. Use a well-known language description. If you have two website names: Chinese and English, try to use the one you are familiar with as the title description.
 

Meta Information
Meta description is a part of the meta tag, which is located in the Meta description is a concise summary of the webpage content. If the description is consistent with the webpage content, Baidu regards the description as one of the targets of the abstract, A good description will help you easily determine whether your webpage content matches your requirements from the search results.
Meta description is not a reference factor for weight calculation. The existence of this tag does not affect the webpage weight. It only serves as a selection target for the search result summary.

 
Recommended Practices: 1. description is the best choice for webpages with no large text segments, such as the homepage, channel page, and product parameter page. 2. Create different descriptions for each webpage to avoid using the same description for all webpages. 3. Reasonable length, but not short.
 

ALT
We recommend that you add ALT to the image.
In this way, users can understand the information to be transmitted when images are not displayed at a low speed, and search engines can also understand the image content.
Similarly, when using images for navigation, you can also use alt annotations to tell the search engine what the webpage content is.

Flash Information
Baiduspcan only read text content. Non-text content such as flash and Images cannot be processed temporarily. Text placed in flash and Images cannot be identified by Baidu.
Therefore, if you must use flash, we recommend that you add comments to the object tag.
This information is considered as the description of flash. Allows search engines to better understand your Flash content.

Frame
It is not recommended to use frame and IFRAME frame structures. The content displayed through IFRAME may be discarded by Baidu.
