Analysis of some factors affecting the ranking of websites

One, the search engine normal update. As the search engine updates the master index, your competitors better optimize their site, or have new sites to join. This is a normal factor, as long as you are normal to maintain the site, and often update the content of your site, it is likely to be ranked in front of your competitors.

Second, the search engine algorithm changes. As a result of the search engine algorithm changes caused by the drop in the ranking is also a normal factor, as long as you improve the existing site disadvantage, to adapt to search engines, I believe your ranking will return.

Third, long-term do not maintain the website. Search engine like new, valuable original articles, so that it will think your site is particularly dynamic, will think your site is very important. If not regularly maintained, the search engine will reduce the level of the page, and even delete the site from the index.

Iv. changes in the structure of the website. Changes to the site structure means that search engines are reassessing your site, and it is not surprising that the site's rankings are down.

V. Web server issues. If there is a problem with the server, the search engine will not be able to crawl and update your site, will temporarily hide this site from the index, after a certain period of time will think that this site no longer exists, and finally delete the site from the index. Therefore, to have a good ranking, the most basic server security must be done well.
