1. Change website programs frequently. Many new users often change website programs based on their personal preferences because they do not have a deep understanding of SEO. As we do not know, when the website was built, the spider formed a crawling rule for the site. The sudden change of website programs will make the spider identify unclear, and eventually lead to a reduction in the search engine's indexing. In serious cases, the website can be downgraded.
2. Change the title frequently. Title text is particularly sensitive. In fact, the title is like a double-edged sword. If it is used properly, it will give you a high weight, you will be taken care. Title changes often result in downgrading.
3. Select a non-div + css program. As we all know, div is very friendly to search engines. All styles are in CSS and only the ID part of the body is called. Obviously, the text code and HTML code are reduced, the text is highlighted, so it is easy to be indexed by search engines.
4. Select a program that cannot generate HTML. Website programs that can generate HTML pages should be the first choice for most SEO people. Basically, what keywords can be searched casually. html-based pages must be placed at the top of pages in other languages. This is a common knowledge for new SEO beginners.
5. Add junk links randomly. Generally, large Internet companies divide links into one department. It can be seen that links are very important. Some webmasters just set up their websites to search for external links like headless flies. No matter whether they can help them, this is extremely undesirable. In the search for external links, the first is, it depends on the PR value of the other website. Second, it depends on the number of friendship links of the other website. Third, it depends on whether the other website ranks as cheating. Fourth, it depends on whether the other website has been downgraded. Fifth, it depends on whether the website server of the other party has been downgraded (only large companies can do this well ). In friendship links, I usually require text links. After all, I can't count on the traffic that friendship links can bring to you, and text links will let the spider crawl directly ......, It is equivalent to a domestic spider.
6. Pay attention to the keyword density. Many friends like to set the keyword density very high, and even several keywords appear in a row. This is completely incorrect. In severe cases, the search engine K will be dropped, so the keyword density should preferably be controlled from 2%
