Site overnight ranking Total drop reason analysis

Today to see a participant in our SEO optimization training of the students of an SEO case analysis, his site is like this: Before the site's trademark transfer, trademark trading, trademark transactions and other keywords are in front of the first several. During the site did not make any changes, but then the 2011.11.30 day, the site Baidu keyword ranking all night, 2011.12.1 ranking recovery, 2011.12.2 has not been the ranking has been restored.

Get this site, I simply looked at the site, and did not see what the problem, the site is not a new station, and the site is still in the increase, the chain is also increasing, keyword density, friendship links and so do not have much problem, the home page also did not show the right to reduce the phenomenon. So what is the reason for this site to drop the rankings?

　　

　　

Let's go over the deep analysis again.

　　

　　

　　

From the above, I think we should see that the site's ranking changes, the home page gradually appears to be the trend of decline, product this column page is beginning to appear in the rankings of nothing, in addition to see Google rankings, Trademark trading home page ranking in the third, Brand Trade ranking Product column page in Google 7th, the trademark transfer rankings home in Google 11th, Product column page ranked 132, this let me find this site's problem is really the search engine to the wrong ranking problem, meaning should be to the first page of the ranking to the column pages, The cause is Product column keywords and home conflict, and this site's news page a lot of the inner chain is pointed to this section page, and the key point to the first page is very inaccurate. Cause now the search engine can not judge you do those keywords are the home page or this column pages? The time is long to cause two pages have rankings, but the rankings are not very good.

There is also a part of the reason is that the weight of the page is this section of the site diversion of the past, to do is to restore the weight of the website to the home page, so that the home page to participate in ranking, you can restore the rankings.

Specific solutions:

1, the column page of the key words to adjust to the relevant long tail words, do not and the first page of the conflict.

2, cancel the entire station bottom density exceeds the link, keep a point to the home can,

3, the appropriate increase in the homepage keyword density,

4, the inner chain only points to the home page and only with accurate trademark transfer, trademark trading and so on.

5, links part of the reason

This problem, we can also see that Baidu search engine and Google search in the site ranking mechanism is still some different, this site is still so good in Google rankings, mainly in Google's external links to see the particularly important, the site's external links do most of the home page, anchor text is of course the above several main keywords. On the contrary, Baidu is more interested in the content of the site itself, the other is Google's search ranking processing technology is really very cow, will not be confused about which page the site is to participate in the rankings.
