為什么有的網站百度收錄了幾千篇文章，而經過一段時間快照會返回，讓收錄也只剩下首頁？難道是被百度給懲罰了嗎？還是有幾它的原因呢？下面我們來分析一下：

Why do some sites Baidu contains thousands of articles, and over time will return a snapshot for your home are left? Could it be Baidu to punish it? A couple of its causes? Let's analyze:
　　大家都知道百度跟新一般在10-15天，在這次的大更新中，肯定是有人歡喜有人愁，歡喜的人是因為自己網站在這次百度的大更新中，有了新的突破，有人愁那肯定是因為自己在這次的更新中有的網站收錄毫無動靜，還有更郁悶的站長，網站的收錄沒有增加，反而減少很多收錄，更嚴重的只剩下首頁了，為什么會有這些原因呢？第一頁SEO就這一問題分析如下：

We all know that Baidu is generally 10-15 days with a new, major update in this, certainly some people are happy others are sad, happy people because their site Baidu in the big update, with new breakthroughs, Some people worry because they will definitely be in this update, some sites included on no movement, there are even more depressed webmaster, your site does not increase but reduce a lot of your more serious left home, why there will be those reasons?

　　第一：為什么我的網站會在百度大更新中收錄創下奇跡。
　　我自己制作的一個網站從建站到現在才1個多月百度收錄近4000篇，很多站長肯定很羨慕吧？很多網站建站可能有好幾年了，但是老是收錄才幾百篇，有的只有10幾篇，那么你有沒有發現其中的問題
呢？下面介紹下我建站到現在所做的工作。
　　1、網站內容定時更新，最好每天更新，保持一周內至少3天更新。
　　2、首頁標題定位了不要再改動(這條非常關鍵要不然會出現快照回滾的現象)
　　3、注意文章關鍵字、描述還有文章關鍵詞密度一般在2%-8%之間為最佳。
　　4、每天更換3-6個高質量的友情鏈接(什么是高質量的鏈接，前文已經說過了，感興趣可以搜索查看)。
　　5、網站的友情鏈接不要超過50個(這是非常關鍵的如果太多的友情鏈接會被百度直接降權甚至被“拔毛”)。

First: Why my website will update your record Baidu great miracle.
I made a website from Jianzhan to just over one month now contains nearly 4000 Baidu, many owners must be very envious of you? Many sites Jianzhan may have for several years, but it always contains hundreds of articles, some only 10 a few, then you have found the problem
What? Here I am the Jianzhan to the present work.
1, regularly updated web content, preferably updated daily to keep updated at least 3 days a week.
2, page positioning not to change the title (this is critical or else there will be a snapshot rollback phenomenon)
3, note the article keywords describing the article keyword density are generally between 2% -8% for the best.
4, daily replacement of 3-6 high-quality links (links to what is high quality, previously have said, interested can search to view).
5, the site links do not more than 50 (which is very critical, if too many links will be right down Baidu directly or by "plucking").

　　第二：為什么有的網站會在百度更新中沒有增加收錄甚至降低收錄
　　1、網站首頁標題大動干戈、亂改動(這是非常重要的如果你亂改標題一個月之內超過5次，那么你被百度K的概率是99.99%)
　　2、網站內容在一夜之間忽然增加了N多內容，多數是通過網站采集，俗稱垃圾站。
　　3、網站的友情鏈接出現嚴重問題，比如你鏈接到被百度懲罰的網站
    4、網站含有惡意代碼，被用戶舉報，導致網站收錄被百度刪除。
    5、同網站服務器上有網站被百度懲罰，連累了你的網站。
    如果你的網站收錄不是很好，看看是不是存在上述中的某一條，如果存在，盡快修改，如果你有更多的心得與大家分享，歡迎交流。

Second: Why do some sites did not increase in Baidu update your even reduce your
1, the site home page the title go to war, chaos change (this is very important to chaos if you change the title more than 5 times within one month, then you are Baidu is the probability of 99.99% K)
2, content sudden increase in the overnight more than N content, mostly through the site acquisition, commonly known as garbage station.
3, the site links serious problems, such as you link to the website to be punished Baidu
