在做网站优化的时候，难免会遇到网站排名下降的问题，今天做济南网站优化的公司济南嘉晟网络科技为大家总结了一些网站排名下降可能的原因：
In website optimization will inevitably encounter the problem of website ranking drop, Jinan site optimization company Jinan Jia Sheng network technology today we summarizes the likely reasons for the decline in some website ranking:
1、服务器问题
1, server problems
最基本的问题之一，如果服务器出现问题的话，搜索引擎就无法对你网站进行抓取和更新，会暂时从索引中隐藏，经过一定的周期后会认为此网站已经不存在，排名也全没有，最后从索引中将网站删除。所以，要有好排名，最基本的服务器保障一定要做好。
One of the most basic problems, if the server problems, search engines will not be able to grab and update your site, will be temporarily hidden from the index, after a certain period of time will think that this site has not exist, the ranking is not, and finally from the index will be deleted. So, to have a good ranking, the most basic server security must do a good job.
2、错误的使用了robots.txt文件
2, the error of the use of the robots.txt file
搜索引擎在抓取页面之前先检查是否存在robots.txt文件，robots.txt文件设定网站中哪些页可以被索引，哪些页不可以被索引，所以，如果定义错误了robots.txt则会影响搜索引擎对页面的索引。
Search engine to check whether there is a robots.txt file, robots.txt file to set the site in which pages can be indexed, which pages can not be indexed, so if the definition of the error of the robots.txt will affect the search engine on the page index.
3、错误的优化
3, error optimization
修改了Title、Meta等标签，搜索引擎抓取新的标签和描述需要一个周期，在这个周期中，搜索引擎为确保数据的准确性，不会马上进行更改，会不断的与以前旧标签进行比较，确定后才进行更改，在这期间，某些关键词的排名很可能消失。导致无排名。
Modified Meta, Title and other tags, search engine grab a new label and description requires a cycle, in this cycle, the search engine to ensure the accuracy of the data will not be changed immediately, and the previous old label to determine the change, in this period, some keywords ranking is likely to disappear. Lead to no ranking.
4、作弊
4, cheating
你可能使用了不正当的手法进行了优化，即作弊。你可能是无意识的作弊，可能触发了搜索引擎某些不被接受的方法进行了优化。如：最常见的就是字体颜色和背景颜色一样。举个例子：有一个表格，背景颜色默认是白色，而你可能使用了黑色的背景图片，但为了突出内容，将字体颜色设置为了白色，这就触发了防作弊机制。
You may use an improper technique to optimize, or cheat. You may be unconscious of the cheating, may trigger some of the search engines are not accepted by the method of optimization. For example: the most common is the font color and background color. For example: there is a table, background color is white, and you may use a black background image, but in order to highlight the content, the font color set to white, which triggers the anti cheating mechanism.
