The content of the site is to consider a quality of the site a big standard, so we update the site every day, attention to the site included. A computer Check site included changes seem to have become a lot of webmaster habits, looking at the increase in the amount of our will be delighted, on the contrary, if included daily decline, then we will be anxious. In fact, we can avoid or eliminate these anxieties, as long as we clearly know that the site may be included in the decline of factors, we "prescribe the right", we can avoid or eliminate such a decline in the situation. So, what factors will lead to the reduction of the site included? Included in the reduction we can be divided into internal and external causes of 2 aspects. Internal cause is mainly the existence of the site's own problems resulting in reduced, and external factors are outside the site. The following excellent used car network small series on the specific to say:

Internal：

No.1, server unstable: For the server to stabilize this point I think we all read a lot of relevant articles, for a website, a good server is the "revolution" of the fundamental, if the server instability Zooey problems, will affect the normal access to the engine spider, the most direct result is to lead to decline in ranking, Included reduced.

No.2, the quality of the content is not high: the author of the promotion of excellent second-hand car network has been good before, because in the content of less kung Fu, are from other sites to copy some content over, the title slightly modified, the content is almost no change, And we all know that the search engine algorithm has long been able to distinguish some of the site's duplication and low quality content, and the author of this site included a decline. So to ensure that the site is not reduced by one of the conditions is to ensure the quality of content in the station.

No.3, website revision upgrade: Website revision is like a knife to do surgery, regardless of the size of the operation, will affect the local, perhaps "operation" is to better "survive" to bring users a better experience, but the search engine for this change in the face more sensitive, it will feel you unfamiliar, will be new to you to observe. In any case, every time the revision is bound to make a certain negative impact on the site, included in the reduction is inevitable, so if you want to ensure that the collection is not greatly reduced please do not frequent revision.

No.4, the use of black hat cheating: no matter which line which industry will be some opportunistic do not take the usual road, SEO is also, a lot of webmaster Yukung Hali, not down-to-earth walk, and choose to go some extreme, which is what we call Black Hat technology, Perhaps Black hat technology in the short term can deceive the search engine so that your site in a short period of time to include a large number of increases, but the search engine it is not so silly, it can also detect in a certain time you are cheating, and it also hate this behavior. As a result, it is conceivable that light will reduce the site included, heavy pull hair K station. Therefore, the website optimization Although there are shortcuts to go, but we still need to down-to-earth, solid operation.

External：

No.1, search engine algorithm change: We know that the search engine it is not a dust unchanged, it will be updated every time the algorithm, and each update, will be more or less to increase or reduce the site included. Of course, in this case, we do not worry too much, to calm down, the algorithm is inevitable change, no matter how it changes, we just step by step. As long as the rules of the optimization, it is not afraid because of the algorithm changes caused by the reduction.

No.2, the website is attacked or hangs the horse: perhaps many people did not encounter this kind of situation, but here also has to say to everybody. The website is attacked hangs the horse to be very normal matter, because of the normal so many stationmaster headaches, the website one is hanged the horse will be inexplicably many piles of messy links and so on, moreover this if does not pass the FTP to see modifies the file the time to be difficult to discover which file was modified. Even if you modify the source file code, it will make the search engine, reduce your site included, to your site review. Therefore, here to remind the general webmaster must ensure the safety of Web server, do a good job of defense!
