Brief Introduction to SEO search engine optimization design and development experience
1. Include keywords in the URL.
2. A page may consist of two or three paragraphs. The section contains keywords and descriptions of keywords.
3. Text paragraphs rich in keywords should be as close as possible to the front of the page code.
4. Use the header label. <H1> </H2> contains the most important keywords and <H2> </H2> contains secondary keywords.
5. html files should not be too large. Search engine crawlers cannot crawl the page content.
6. The image must use ALT to write the description and contain keywords.
7. Use text links instead of image links.
8. Try not to use js dhtml. You can use CSS to achieve some page effects.
9. Do not use the framework structure. The framework structure will lead to a loss of search engine crawlers.
10、ensure that robots.txt is correct-do not use robots.txt if it is not used.
11. Use 301 instead of 302 to jump to the page.
12. Do not use the question in the URL.
13. Keep the HTML code concise and orderly.
14. Use table as appropriate. It is better for Seo to use CSS for layout.
15. Do not place pages with the same content on the same site. search engines are disgusted with this spam behavior.
16. Use the welcome page with caution. Generally, only some images or Flash files are available on welcome pages, and few texts are available. This is unfriendly to search engines and prevents crawlers from entering real information-rich pages.
