在做網(wǎng)站優(yōu)化的時(shí)候，難免會(huì)遇到網(wǎng)站排名下降的問題，今天做濟(jì)南網(wǎng)站優(yōu)化的公司濟(jì)南嘉晟網(wǎng)絡(luò)科技為大家總結(jié)了一些網(wǎng)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、服務(wù)器問題
1, server problems
最基本的問題之一，如果服務(wù)器出現(xiàn)問題的話，搜索引擎就無法對(duì)你網(wǎng)站進(jìn)行抓取和更新，會(huì)暫時(shí)從索引中隱藏，經(jīng)過一定的周期后會(huì)認(rèn)為此網(wǎng)站已經(jīng)不存在，排名也全沒有，最后從索引中將網(wǎng)站刪除。所以，要有好排名，最基本的服務(wù)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、錯(cuò)誤的使用了robots.txt文件
2, the error of the use of the robots.txt file
搜索引擎在抓取頁(yè)面之前先檢查是否存在robots.txt文件，robots.txt文件設(shè)定網(wǎng)站中哪些頁(yè)可以被索引，哪些頁(yè)不可以被索引，所以，如果定義錯(cuò)誤了robots.txt則會(huì)影響搜索引擎對(duì)頁(yè)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、錯(cuò)誤的優(yōu)化
3, error optimization
修改了Title、Meta等標(biāo)簽，搜索引擎抓取新的標(biāo)簽和描述需要一個(gè)周期，在這個(gè)周期中，搜索引擎為確保數(shù)據(jù)的準(zhǔn)確性，不會(huì)馬上進(jìn)行更改，會(huì)不斷的與以前舊標(biāo)簽進(jìn)行比較，確定后才進(jìn)行更改，在這期間，某些關(guān)鍵詞的排名很可能消失。導(dǎo)致無排名。
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
你可能使用了不正當(dāng)?shù)氖址ㄟM(jìn)行了優(yōu)化，即作弊。你可能是無意識(shí)的作弊，可能觸發(fā)了搜索引擎某些不被接受的方法進(jìn)行了優(yōu)化。如：最常見的就是字體顏色和背景顏色一樣。舉個(gè)例子：有一個(gè)表格，背景顏色默認(rèn)是白色，而你可能使用了黑色的背景圖片，但為了突出內(nèi)容，將字體顏色設(shè)置為了白色，這就觸發(fā)了防作弊機(jī)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.
