What does SEO optimization include?

SEO optimization includes four directions: internal structure optimization, content optimization, internal chain optimization and external chain optimization.

I internal structure optimization 1. TDK Optimization: The TDK here is not only the home page, but also the TDK of columns page and the article page, which is why you can choose a custom label when building a website. T is title, the title of the website, very! Heavy! Yes! If the TDK score is 10, t should account for about 7 points. The title is the first sight of the spider, which is the first impression. The title must contain keywords, that is, the function of the website, what products or services the website does, and fluent sentences. Don't pile up keywords D is description, website description, which is a supplement to the title. K is the key word, and columns page and TDK of the article page can be found in the advanced settings of specific columns in the background.

2.30 1 redirection and 404 error page making must be available, and there is nothing to say.

3. hierarchical directory: that is, how many levels are needed to open a page, which is ignored by many websites. It is suggested that the time required for spider crawling should be reduced to less than level 3.

4. Keyword layout and density: deploy keywords to corresponding places according to the click hotspots found by users clicking on browsing pages. That is, F layout, the keyword density in a page is kept within 2%-8%, which is only empirical data and not necessarily accurate.

5. Ubiquitous words: TDK+ suffix or anchor text.

6. Website navigation: primary navigation, secondary navigation and breadcrumb navigation, including keywords, highlighting key points and using plain text, which should be consistent with the corresponding TDK.

Second, content optimization mainly means that the quality of articles should be high, even if it is not purely original, it should at least be highly pseudo original. Pseudo original should choose articles on the website that are not included or blocked by search engines, or translated articles. As long as it is the first article you send, the spider thinks it is original.

Third, to sum up, internal chain optimization is to increase the link density in the site, just like a spider web, the denser the better, and the most common is the mutual jump of home page, column and article page; LOGO links, article pages use TAG tags and previous, next or related articles to increase the number and relevance of links between pages.

Fourth, the last thing to say about external chain optimization is that SEO optimization is a long process, so don't overdo it.
