In judging whether the site is down right, the first thing to be clear is: Search engine punishment is not easy to detect, the site of some of the ranking of key words, the decline in traffic is due to be punished or because of search engine algorithm changes? Or are new competitors joining in? It is difficult to distinguish between these situations accurately. So only a full grasp of the site to reduce the right to some of the possible factors in the operation, as far as possible to avoid, not to let the site down right.

And the site is often the right to drop a number of factors caused by the site, search engine will not because of a certain point of the site down the right (comprehensive factors), resulting in the site down the right factor is nothing but three major points:

1, web site changes caused by the site directory, the path of change triggered down the right

2, inferior site: inferior site judgment (dead chain took more, repeat the page too much, user experience poor or collection station, the site often not normal access), etc.

3, the optimization of cheating or optimization errors (frequently modify the site title, piling up key words, trading connections)

If you want to very good analysis of whether the site is down the right to have to master-"site down the general performance of the right", "the site down the general factors" can be a better analysis of the site down the right reasons.

1. What is the general performance of the site down right?

Web site by the search engine down the main performance of the right is generally divided into the following (ie, the right to reduce the standard of several factors)

1.1, the homepage is k, only the inside page

Parsing: When retrieving http://www.domain.com or retrieving the title of the site, look at the first is not the site, if not, then the site is down right!

Cases：

So can not blindly think that site is not the first place is the right to drop. Site site is not the first page of the website is not necessarily the right to be down, the right to drop the site must not be in the first place.

Often lead to the home page by K This situation most of the quality of the site is not high, here the "quality of the site" is not simple to think is the content is original, but contains too many things such as site title recurring changes, site cheating, optimization is not high quality of the site is a performance.

1.2, the Site page is k only left home.

Parsing: When the query site is included in the page, only the homepage of the site. In addition to a lot of new webmaster time optimization is still after the search engine included the home page, the right to reduce the occurrence of

Basic can be identified as the site has been inside the page by K.

This situation may cause the site server factors (whether stable), the quality of the content is poor (a large number of collection, or repeat the page too much), etc. may be within the Site page K.

1.3, the site included She, under normal circumstances, the number of sites included a small fluctuation is normal, Baidu included She, not dozens of pages of hundreds of pages disappear, but overnight thousands of tens of thousands of included disappeared.

1.4, the keyword ranking suddenly disappeared, not to drop a few pages ranking, but dozens of pages of hundreds of pages even without a trace.

Parsing: Keyword ranking from the first page fell to the second or third page, this situation is normal (search engine algorithm changes) General site has been using white hat SEO optimization techniques to optimize the site, there are few keywords at the same time significantly reduce the situation. When the site most of the keywords are at the same time a large area of decline, this is obviously very abnormal.

Hit the site keyword ranking large area decline, first consider whether the site has improper black hat SEO optimization.

Second, the survey site keyword ranking volatility is a case or a general situation. If the situation is widespread, it is likely that the search engine ranking algorithm for large adjustments. In addition, can also observe the site at this time whether there are several lower right performance.

Second, causes the website to reduce the power the factor

1, server instability (check server header information IIS log file)

The result is because the internal changes in the site to reduce the right to view the IIS log, see the spider visit our site What is unusual, such as 404 page is not a lot, if too much check site 404 page entry and clear, use robot to screen the 404 pages and customize 404 pages. Check to see if 500 or 503 of this server instability occurs.

2. Check Robots.txt file

Check to see if the Robot.txt file is used, and if so, have you recently modified it, causing some grammatical errors that prevent the search engine from indexing your site? There are potentially many unexpected error factors in the Robot.txt code, If you want the search engine to include your whole

Site, you can not have to place robot.txt files, by default, search engines will include your site is not protected by password content.

User: *

Disallow:/

This will cause the search engine to be unable to crawl site content

3, check the Web page Meta section of code

Check the page Meta section for NOINDEX:

Example:< meta name= "robots" content= "Noindex,nofollow"/>

Tell the search engine not to lead and not track this link

4, thoroughly check whether the site optimization excessive

A, look at the page is there any key words piling suspicion: Title piling keywords. Many webmasters in order to improve the site keyword density and keyword ranking, are written on the title a long paragraph, generally 50 characters, but repeatedly piling a keyword many times, so that the formation of the title is not standardized, the existence of the suspicion of piling keywords, nature will be down right.

B, whether there are links in order to add inside the link

C, whether the anchor text over centralized optimization (inside and outside the station)

D, whether the footer appears to the user is meaningless, only in order to cater to the search engine to prepare the link and the text

5, outside the link factor (outside the chain mass loss or the chain mass, the bad garbage cheat station automatically gathers when the link)

Outside the chain of mass, bad garbage collection automatically collected when the link, these links have a feature is poor correlation, stability is poor, search engine recognition will automatically filter in the link calculation and take off the weight of this part of the chain, so trigger down the right.

A lot of loss of the chain, such as post is deleted, or blog is closed, then may cause the loss of the chain.

6, check and delete suspicious links (the so-called suspicious links include the following several)

A, Links

Station group Mutual chain: This Baidu clear hit to like (http://zhanzhang.baidu.com/wiki/160)

With the right to be demoted to each other chain:

For the new station, the home page in the short term to add a friendship chain to take over, especially the high weight of the link, beyond the normal development of the new station.

B, the footer appears only to cater to the search engine to prepare for the link (a large number of back links or stacked within the chain).

C, export links unrelated to the subject content of the Web site.

7, check whether there is duplication of content (or a large number of low quality content collection, a lot of spam information.) )

Duplicate pages include (the same content on different URLs of the site itself, including a lot of the same content as other sites)

8, the Web site changes caused by the path modification and change, resulting in a large number of dead links in the station.

9, the content and the subject of poor correlation (user experience is not high)

User Behavior Analysis: The user's stay time, user's access depth, turning rate, UV, PV and website bounce rates

Site Relocation: Analysis of user needs, do a good job of content timeliness, resource scarcity

10, serious cheating behavior: buy and sell connection, hidden link, malicious code.

A, a site on the site page with a large number of malicious ads, malicious code or harmful Plug-ins website

B, hidden links This is the way we often say black chain ()

C, the difference between normal advertising and cheating means there is a very vague boundary. But the person who does this is very clear in his own mind. If your site is considered to be cheating by buying links, there is no way to argue with search engines. Because the search engine decision is the final decision.

11, the search engine itself problems and algorithm adjustment are normal phenomena: first analysis about 15 days whether there is any cheating, if not the first observation for a period of time do not be urgent to modify or adjust.

12, have the courage to know when to give up

Do not say webmaster often confused why the site is punished, so it is difficult to completely correct, is to find out why the site was punished, cleared the suspicion of cheating, may not be able to restore the site.
