One of the criteria used by the search engine to judge the integrity of the site is the number of external links and the quality of the site. The creation of gaseous and meaningful linkages and their wider reach can raise the ranking of search engines and also serve as a means of promoting each other. Research shows that when a site has a four-to-six link, the page has better access; when a seven-to-seven link has a good quality and visibility
Web pages are divided into static and dynamic pages, which are interactive pages, i. E., pages that return data through database searches, so that search engines take longer to search and, once the contents of the database are updated, search engine capture data is no longer accurate, so that search engines rarely capture dynamic pages and are poorly ranked. The static web pages do not have interactive features, i. E. Simple information presentations, search engines take short and accurate time to search, so they are willing to be recorded and ranked better. The website should therefore use static pages to the extent possible and reduce the use of dynamic pages. The smaller the web capacity, the faster it is, the more friendly the search engine spider program is, the more streamlined the HTML code is used to produce a web page, which normally does not exceed 15 kb. Java. SCript and css are separated from web pages to the extent possible. Use of more standardized xHTML and xml as display formats should be encouraged, following the w3c norm。
Based on people's usage habits and mentalities, the more websites are ranked in the search engine, the more likely they are to be hit, and, on the contrary, the less traffic they receive when ranking is lower. According to statistics, more than 90 per cent of companies worldwide have imported seo technology into their websites。
