Engaged in a year of Seoer, has gradually developed into the office every day the first thing is to check the site's collection of the habit of the chain. I think most of the optimization staff will have this habit, looking at the increase is like watching our children grow up day by day, when we encountered not increase or decrease in the situation, I think as every optimization staff will have a little bit of loss in mind. This is not, recently I a new station just from more than 100 of the collection down to more than 10 (site for the enterprise site, content has certain limitations), has passed the audit period, just opened articles are seconds, but now not only not included, but also in the continuous reduction, as shown in the following figure. After a phase of processing, currently included has tended to stability, today I will be in the process of dealing with this problem to get a few reasons to share the reduction.

Included in the reduction generally we can be divided into subjective and objective reasons. The reason is that our site itself exists as a problem, and this is generally caused by the site is not included in the main reasons. And the objective reason is some external influence factor, to the site collection also plays the certain influence function.

Subjective factors

1: The quality of the site content is not up. As the author of the site encountered the situation, because the author's site is a corporate site, in the content of the article has certain limitations, and there is not enough content. So I can only through a number of repetitive content or some false original content to enrich the site. and search engine algorithm has long been able to distinguish between site duplication and some low quality content, this is caused the author site is not included and included the main reason for the decrease. Therefore, the author believes that as the site of the main reason for the reduction of the blame and its own factors in the quality of the content.

2: Server instability, in the selection of servers in this issue, there are many articles have been elaborated. A good server for a site is like having a good body, and the body is the capital of revolution. If there is a problem with the server Zooey, don't talk about optimization. If the server is not stable, the most direct result is the site's ranking and included lower. Search engine spider Crawling our site is like an ordinary visitor, if the spider can not open our site, then needless to say crawling included. And after a few times, spiders will think that your site has been closed, and no longer visit your site.

3: Use Black Hat technology. The so-called body is not afraid of the shadow crooked. For us to optimize the staff as long as the use of formal optimization technology is not afraid of search engine punishment. But because of the trend of interest, a lot of webmaster still at risk, using black hat technology to optimize the site. In the short term may make your site contains a large number of increases, but after the search engine will review you, and finally by reducing the number of your collection to punish you.

4: Website revision upgrade. The revision of the website is unavoidable for every website. And thus the inclusion of the reduction is inevitable. We should reduce the frequency of changes to the site, to achieve the maximum reduction because of the impact of the revision.

Objective reasons

1: Search engine algorithm update. For each search engine algorithm update, many webmaster will find that there may be increased or reduced situation. For this situation, I think as a webmaster should be calm, the algorithm update is unavoidable, search engine how to toss is their thing, as long as our site to do optimization, not afraid of search engine changes.

2: The site is attacked or hangs the horse. As our webmaster, the most depressing than the site was attacked or hung horse, the author's site has been hacked. And even more depressing is when you encounter this kind of problem, you can only see the file through the FTP changes time to determine which file has been modified. And when you modify the source files to the site, the search engine may think that your site is a new face, you may have to face a search engine review of the dilemma this is likely to lead to lower site. And the site is attacked caused by instability or hanging horses will cause the search engine on your site generated distrust. This will eventually affect the inclusion.

There are many reasons for the reduction included, only to find the real reason, in order to adapt to local conditions, timely and suiting the formulation of the strategy. This article by DNA paternity identification http://www.tuan-shanghai.com edit, reprint please keep the source.
