Chu Shijian's resume: Which aspects should we focus on when optimizing website structure?

The website structure has been optimized to make the website layout more reasonable. A reasonable website column structure can correctly express the basic content of the website and the hierarchical relationship between its contents, and consider it from the user's perspective, so that users can quickly find the information they want when reading on the website. Search engine spiders can come to our website unimpeded, and every page is unimpeded, so where should we start with website structure optimization?

First: Clear directory structure. A concise directory structure and standardized naming are not only beneficial to user experience and URL communication, but also a manifestation of search engine friendliness, which is reflected in the following aspects:

1. Directory access level Directory access level refers to how many levels you have to go through to access the final page. When the website directory level is greater than 3 levels, you need to use the second-level domain name to expand the level. Because the first-level domain name can be regarded as an independent website directory hierarchy 2. Directory and file naming according to the principle of keyword omnipresence can use keywords in directory names and file names, but if it is a keyword group, it needs to be separated by separators. We often use hyphens "-" and underscores "_" to separate them, and space codes "%20" are often present in URLs. Therefore, if "hostease coupon code" is used as the file name, it may appear in the following three separated forms> hostease-coupon.htm> hostease_coupon hmm> hostease%20coupon htm

Which delimiter should be used? We can get inspiration from the naming conventions of domain names. For example, when requesting a domain name, only "-" can be used as a separator, but not "_" or space. It can be inferred that for search engines, "-" is friendlier than space and "_".

Second: URL
1. Definite URL and relative URL
Definite URL means using a complete URL to point to a specified web page. A relative URL refers to the use of an automatic URL to point to a specified web page. For example, for a specified web page: "/product/index.html" is a relative path. For a relative path, the browser will automatically add "" in front of the link.

2. Dynamic URLs
Currently, many websites have database-driven URLs, that is, dynamic URLs, which often show characters such as "?", "%", "=", "%" in the URL, which is extremely unfavorable for search engines to crawl web pages and seriously affects website rankings. Dynamic URLs can be converted into static ones through technical solutions.

Third: Navigation structure
1. The main navigation is eye-catching and clear. The main navigation is usually presented as a first-level directory. Through them, users and spiders can go deeper and deeper, visiting all the links on the website instead of just the images. For example, the navigation bar of the webmaster encyclopedia download site is a first-level directory, and the homepage source code is the ASPNET source code.

2. In addition to the main columns, the important content in the secondary directory should be repeatedly presented on the homepage or other sub-pages in the form of links to highlight the key points. Search engines will pay full attention to such links that appear repeatedly on a website, which is of great help in improving the page rank (PageRank). It is also an important reason why the rank of each website's homepage is generally higher than that of other pages, because each sub-page links to the homepage.

3. Use site map. Site map is a method of auxiliary navigation, which mostly uses text links to speed up page loading, especially for those web pages generated by image navigation and dynamic technology. By making text links in the site map, it can to a certain extent make up for the risk of invisible pages caused by spider programs being unable to recognize images and dynamic web pages.

Fourth: Structure, structure, and frame structure (Frame), including IFrame and Frame. If the web page already uses a structure, or must use a structure for some reason, the NoFrame tag must be used in the code for optimization. Treat the <NoFrame> tag as a homepage with ordinary text content. Include a link to the Frame page and descriptive text with keywords in the <NoFrame> </NoFrame> area. At the same time, keyword text will also appear in areas outside the structure. This allows search engines to correctly index the information within the structure.

Fifth: Image optimization
1. Try to reduce the size of image files while maintaining image quality.
2. Alt attribute: Each image has an Alt attribute in the <IMG> tag, and the search engine will read this attribute to understand the information of the image. Therefore, it is best to add text descriptions to the Alt features of all illustrations and put the keywords of the page in them.
3. Add descriptive text including keywords above or below the image.
4. Use the link to link to this image.

6. Flash Optimization
Flash will make the page look good. However, Flash web pages have a very fatal problem, that is, most search engines cannot recognize the information in Flash. So use as little as possible.

Seventh: 404 error page settings In web page settings, it is common to present errors, but we need to set a default page for this error page, make it an information page, and guide customers to visit our website.
