The most of the problem is that the site is included in the constant disappearance, although the number of likely to disappear is very small, immediately will not see what impact, but this reflects a problem, that is the site is moving in the wrong direction. The normal site optimization is to enhance the collection and site rankings, and included in the reduction means that the site itself has been a bad situation. For this problem the author's site also appeared, as shown in the following figure:

From the above figure we can see that the author of the site every day included are constantly disappearing, for the reduction included, nothing but the station outside and station factors, the author analyzed the chain situation, found that the chain is still in a stable state, so I think the situation should be analyzed from the station. So what are the problems in the station may lead to the site's collection of decreasing?

One: The content of the site is collected content

Typically this occurs when the site is a pure collection station and a copy-and-paste station. Although the content of these acquisition and replication has just begun to be included, but as the search engine for its database of repeated content of the discharge. We will find that the site of those collected on the web with a high degree of duplication of content. If your site is relatively low weight, these included content will be deleted. To this I think, as our site even if there is no way to provide a large number of original content, we can adhere to do part of the original content, part of the use of collection.

Second: content is of no value to visitors

The search engine's guidelines are to continuously improve the user's friendly experience and provide users with the search results they want. For our site only to meet the search engine and users of this condition can have better development. So how do search engines judge the value of our site's content? This depends on the search engine's algorithm. Of course, the basic can pass such as the paragraph format of the content article, at the same time this is also a basic judgment, a typesetting complex content naturally not by the search engine is optimistic. Sometimes, search engines may also be judged by the amount of content they read. To this author and that, to provide search engines and users valuable content is you keep the basis of the inclusion.

Third: Site page URL invalidation

For this we can say that the site appears dead link. Dead link is generally our site upgrade or edit the content of the deletion will be produced, some pages can not be opened to become a dead link, these dead links even if the use of 404 error page will also make the site included a reduction, especially the use of dynamic page site, Because the current search engine for dynamic pages of some special characters crawl is not very good. And the author of the site is obviously because of this cause of the site's collection has been reduced. Because the author of the site in the near stage of the revision, the previous URL address changes.

In the face of the site is reduced, we can not panic, only a multifaceted analysis, to find the reason to really solve the problem of the site. This article by the Daily Bushen network http://www.bushen365.com handwriting Original, reprint please indicate the source.
