About Google included in the number of reasons for the reduction of seven points of attention
One: Google server transfer
Google's withdrawal from the mainland market is a major event in the Internet industry. Since Google withdrew, its servers have also shifted to Hong Kong. Google also occurs sometimes not open the situation, so you can analyze the site included to reduce the transfer of Google server relationship.
Second: the website's renewal frequency reduces, the original content reduces
Google for the content of the site is very fast, and its Google spider is also very active. But for China at present a lot of sites are copied, reproduced the problem, Google's approach is to first include warehousing, and then the original database tutorial to do comparisons, if there is duplication, then the algorithm to delete. As a result, although the site is included in the reduction, it may be related to Google's retrieval of duplicate content.
Third: Website link reason
The quality of external links to the site is not high, or external links are not stable, Google's attention to your station may also be reduced, slowly reduce the contents of the collection. The quality of the connection is very important. Garbage connection would rather not! In addition, check your page, if there is a connection to the blocked station, the resulting chain of death is also very dangerous.
Four: Website revision
The site has not been modified, it has been submitted, encountered feeling bad, do not move to a big change, big update, today, like tomorrow. Category and title for change. There are also times when tests, or other content unrelated to the site, are present. Such sites want to increase the collection is difficult.
Five: Website security
Of course, Web site security and the site's code and the security of the site's servers have a great relationship. A site that is linked to malicious code, Google's confidence in the site will be reduced, which will affect the inclusion.
VI: The quality of the Web server
Web server access speed depends on whether your site in the spider stay in time can be very smoothly included. If the server access speed is very slow, wait a long time to open the site, then the search engine spiders may leave a bad impression on the site, thus a long time to come. Or when you visit a page of a website, more than two consecutive times can not crawl the relevant information, then Google may be from the database to clean up this link information.
Seven: Website cheating or optimization over
For cheating, Google has made a number of statements, found that the site cheats, the light ranked down, the heavy was K. In fact, the division between cheating and over optimization is not very obvious, so in the standard optimization such as keyword density not higher than 8% and so on.
