1、Website optimizationAddresses on web pages have not yet been standardized

When a search engine accesses the content of a page, it will write down the corresponding URL for the page。Once a web page corresponds to two or more urls, the search engine will be overwhelmed and it will "think" : which URL should be selected to display to the user?So, how to solve this problem?

       The first way is to use a 301 redirect to redirect other urls to the only URL you want so that the search engines know which URL is your home page。

The second method is to point all the links to the website home page when publishing the external link, which has the same effect。

2. The website server is unstable

The purpose of a search engine is to present the content of a website to the user so that the user can easily find the information they want。If a website is often inaccessible and users click in search engines but don't get the information they want, this is a waste of time, search engines are not to let unstable websites appear in front of customers。As a result, websites that frequently fail have a hard time gaining the trust of search engines, let alone ranking。

3. Change the title label frequently

Search engines want to know what a website is about, the first thing to look at is the title tag, which is equivalent to the appearance of the entire site。Especially for new sites, frequent changes in title information will cause search engines to distrust, if the title tag is often modified, search engines will inevitably have a sense of distrust of the site, light will reduce the right, heavy will directly K off the site。In addition, this theory also applies to the modification of the website, which often causes the search engine to lose trust in the website。

4. The number of external chain releases has changed too much

The number of outchain posts should be a gradual process, especially when the site is only online。Search engines believe that under normal circumstances, there should not be a large number of external chains。Therefore, the new station should not just release a large number of external chains on the line。Search engines believe that the increase in the number of external links to the website should not change significantly。However, many newcomers, and even some veterans, don't pay much attention to this。When they are free, they release a large number of external chains。When they are away, they have few a day。The rapid change in the number of external links makes it easy for search engines to think that websites are cheating, which can lead to downgrading。
