First of all, the author of a small station to explain the reasons for the fall, as shown in figure:

So, do not put the chain can improve the inclusion of confusion. For the reasons included in the decline, the author analyzes the following points:

Too much repetition of content

This is generally the case of the collection station and copy and paste the station. Such a site, although the new snapshot, included fast, but the search is indexed, found that the same content of the database, and its own weight of the site itself is low, then it will be deleted, so it will appear on their own site included and dropped. To update the original website every day, this aspect of the situation will not appear, do not believe that you can search for the original content of the site, this kind of site will be indexed in order to increase, and will not fall in turn.

Content has no value to speak of

Search is also focused on user experience, so in order to meet the user experience can make their own web site development better. And how the spiders judged the content to be valuable, there are many ways, such as the paragraph format of the article, this is the most basic judgment, a complex content naturally will not have any value to say, can read or a problem, and the content of the mixed with a variety of invalid code, such as useless div tag. These are the ways spiders judge the value of content. And many times, spiders will crawl through the whole station, according to the site's reading to judge, although this is a bit of a chicken, but it is a search to determine whether the content of the site is valuable, for the weight of the site, rarely this situation, reasons you understand.

Content Page URL failed

You can call it a dead link. Many times when the webmaster changes the site code or often revised, will appear a part of the Web page can not open, this is the final culprit of the manufacturing of dead links, and a lot of even set up a 404 of the page also contains a drop in volume, especially the use of some content pages dynamic, because the dynamic of its own web site with some special symbols, so, It is difficult to search, and the author suggested that the content page use a pure static way, so that without changing the link format will not cause too many dead links, nature makes the spider crawling will not go to a dead end.

Should be included in the amount of Web site, should be from the content of the page to find reasons, because the collection is included content page, so, as long as the home page and column pages to ensure the smooth, nature will be moved to the content page analysis. The content page is good or bad with the high and low level of the relationship is unusual.
