最近从事一些优化的SEOer都会发现一个奇怪的现象，很多企业网站建设的个别关键词都出现了大范围的波动，今天还在首页或许明天就掉到三、四页之后了。按照百度正常的算法更新，网站关键词排名不应该出现如此巨大的变动，如果是网站遭受降权，那所有的关键词都应该受到影响呀。很多站长都在QQ论坛里说百度又不正常了，EMC易倍体育官方 中国到不这么认为，看似没有头绪的现象往往都有其存在的依据，SEO网站优化只有透过表面现象寻找到百度变化的踪迹，才能更好的优化自己的网站。
Recently in some optimization of the SEOer will find a strange phenomenon, many enterprise website construction of individual keywords appear larger fluctuation, today is the tomorrow off to three or four pages later. Baidu update according to the normal algorithm, web site keywords ranking should not be such a big change, if the site being down the right, then all of the keywords should be affected. Many webmaster in QQ forum said Baidu not normal, luxuries China to not think so, seems to have no clue phenomenon often has its basis, SEO website optimization only penetrate the surface, to find the changing tracks of Baidu, optimization can better your net station.

网站近期虽然没有使用过什么违规或者作弊的优化手法，网站的优化进度和之前进度一样，那是什么原因导致个别关键词排名突然大范围的下降呢?仔细的分析这些网站的内容，用户点击率和停留时间就会发现，这些营销型网站建设的内容与关键词的匹配度较高，且内容较为丰富。但进一步的发现很多内容都是人云亦云的说，随便摘取一个标题通过百度搜索，都可以得到很多与之相关的内容，虽然文章都是自己伪原创的并没有多少重复，但却不能给用户带来多少有价值的内容。在看用户的点击率和停留时间并不高，部分用户匆匆点击下就离开导致与之关键词相关的页面的跳出率过高。而在查询这些关键词的外链，大都是伪原创他人的文章，虽然也有一些软文投稿，但整体上还是以伪原创为主。
Website without the use of any illegal or cheating optimization technique, optimizing the schedule and the site of the schedule as before, that is what caused the decline of individual keywords ranking suddenly wide? A careful analysis of the content of these sites, users click rate and residence time will find the matching degree, high content and keywords of these marketing website construction, and the content is more abundant. But further found that many are repeat word for word what others say that, just pick a title by Baidu search, can get a lot of related content, although this is false original not much repetition, but not give users much valuable content. Look at the user's click rate and residence time is not high, part of the user to click the left hurriedly to the words related to the page out rate is too high. But in the chain inquires the keywords, mostly false original others article, although there are some soft Wen contribute, but on the whole, or pseudo original.

联想到百度近期刚刚推出的星火计划，随即百度绿萝算法升级到2.0。我们知道百度星火计划的推出就是为了保护网站的原创内容，绿萝算法2.0则是打击垃圾外链，这两个算法的组合更是从内容到外链对原创的重视。EMC易倍体育官方 中国的网站个别关键词排名出现如此巨大的排名波动，个人认为是百度算法变革的结果，按照之前的算法我的网站排在百度首页那是肯定无疑的，随着百度对有价值原创的重视，对用户体验的关注，网站的排名不仅仅和文章的内容、外链等有关，百度又增加了文章的价值和客户的喜爱程度等考核因素，虽然我的网站在之前百度的考核中达到其要求，但在用户体验度和文章的价值传递等还有欠缺，从而在百度新算法下排名出现了下降。
Lenovo to Baidu recently launched the spark plan, upgrading Baidu green algorithm to 2. We know that the launch of Baidu spark plan is the original content in order to protect the site, green algorithm 2 is strike garbage outside the chain, the combination of these two algorithms is from the content to the chain to the original value. Luxuries Chinese Web site keywords ranking ranking individual fluctuations so huge, personally think that is the result of changes in Baidu algorithm, in accordance with the algorithm before my site row in the home page that is no doubt Baidu Baidu, along with the value of the original value, to the attention of the user experience, the site's ranking is not just about the content, such as the chain, baidu added assessment factors in the value and customer preference, although my site before Baidu assessment to meet the demand, but in the user experience and the value transfer, are lacking, thus ranking fell in the new algorithm under the baidu.

至于部分网站关键词小幅度变化的原因，EMC易倍体育官方 中国也谈谈自己的看法：
As to the reason for part of the site keywords small variation of luxuries, China also talk about his own views:

随着百度对文章质量和用户体验的重视，自然在排名时不能忽略了用户的感受了。百度通过对用户行为的检测，可有清楚的知道各个网站用户的访问量、访问时间、用户的忠诚度等数据，假如排在第一位的网站用户点击率和停留时间还没有第二位的高，那么百度自然就认为第二位的网站对用户更有价值，从而把其提升在第一位。由于每个网站的点击率和用户访问时间都是不确定的，难免出现多少不一的情况，自然造成百度排名的不停微调了。当然，百度考核的因素不仅仅是这些，但在网站其他硬性条件都相差无几的情况下，用户体验也就成为了排名的有效依据了。
With the Baidu the quality and user experience attention, naturally in the rankings can not ignore the user experience. Baidu through the detection of user behavior, can know the data volume, various web user access time, user's loyalty, if the web site users click the first rate and residence time is not second bit high, then Baidu naturally think second sites for users to more value, thus the increase in the first place. Because each website click rate and user access time is uncertain, there will be many different natural cause, baidu ranking kept fine-tuning. Of course, baidu evaluation factors is not only these, but in the other site hard conditions are not much difference between case, user experience has become the effective basis for ranking.

因此，企业网站优化要想扼守关键词排名，避免出现不必要的波动，可要从一下两个方面着手：
Therefore, the enterprise website optimization to guard the keywords ranking, to avoid unnecessary volatility, can begin from the following two aspects:

一、文章的质量度
The quality of

百度在推出石榴算法时，就明确了对垃圾网站页面的打击，星火计划的推出更是着重保护有价值的原创文章。企业与其千方百计的寻找各种优化策略和技巧，还不如迎合百度算法发展的方向，重点在文章的质量上下功夫，抛弃以前的转载或者伪原创，努力在原创的基础上提升网站的质量。当然，网站内容的质量不仅仅体现在内容的丰富性、稀缺性、权威性等，更侧重文章传递的价值，带给用户的帮助，只有站长用户的立场为其创造有价值的内容，自然百度也会对我们的网站情有独钟。
Baidu in the launch of pomegranate algorithm, made clear the rubbish site hit, launched the spark plan is mainly to protect the value of the original article. Looking for a variety of optimization strategies and techniques of enterprises and make every attempt, rather than cater to Baidu algorithm development direction, the focus of efforts on the quality of the article, to abandon the previous reproduced or pseudo original, efforts to upgrade the quality of the site in the original basis. Of course, quality of website content is not only reflected in the content of the richness, rarity, authoritativeness, focuses more on the transfer of value, to help users, only Adsense users position to create valuable content for its, natural Baidu will also have a special liking to our website.

二、用户体验 (User Experience)

搜索引擎无论怎么改革都离不开用户的支持，作为其生产的基础就必须获得用户的认可。网站要想在搜索引擎中获得好的排名，就必须做好用户体验，只有用户信任我们的网站才能增加搜索引擎的友好度。提升用户体验的渠道有多种，常见的策略就是提升用户对网站的点击率、延长用户的停留时间、方面用户快速寻找的到需求的内容、引导用户积极的参与其中、增加忠实用户的回访率、减少或者杜绝页面的广告和弹窗等。
Support search engine no matter how reform cannot do without the user, is the basis of production must be authorized users. The site to get good rankings in search engines, it must make the user experience, only the user trust our site in order to increase the search engine friendly degrees. To enhance the user experience by many ways, a common strategy is to enhance the user on the site click rate, prolong the retention time, users quickly find to demand contents, guide users actively involved, more loyal users return rate, reduce or eliminate the page ads and popups etc..

有时为了增加网站关键词排名的稳定，可以适当建设一些高质量的外链，不仅可以起到增加网站流量，提升网站权重的作用，更是对网站的排名起到一种投票的作用。关键是我们在外链建设的过程中，需要贯彻以质取胜，才能保证投票的有效性。
Sometimes in order to increase the site keywords ranking is stable, can be appropriate to build some outside the chain of high quality, not only can rise to increase website traffic, improve website weight function, is a vote of the role of the site's ranking has. The key is that we in the chain construction process, need to carry out quality, to ensure the effectiveness of voting.
