Engaged in search engine optimization friends, should have experienced the site's reverse link (does not contain links) and the content of a sudden decline in the situation, the impact of these reasons? The author's search engine optimization work is "white hat" method, if the use of "Black Hat seo", These reasons may not be the reason why your site is linked and included in the decline. As shown in the following figure, this is the author's current reverse link and content included in the number

　　

Figure I

　　

Figure II

From figure II can be seen, the author's external links are stable, the number of the collection is also stable, so what is the reason for the author's collection and the number of backlinks suddenly dropped so much? Analysis of the author in the reverse link down one weeks before the work

First: Outside the chain construction work, the author has done the business-to-business and the forum outside the chain work (all is the industry related forum), the author inquires these websites, the page which is not included, therefore this should not affect the website reverse link decline the willingness,

Second: Through the video site to establish some external links to work, on how to create a reverse link for the site through video matters, the author will be in the near future and everyone to share, but the link is a plain text link, some video site is also quite fast, is a source of web site backlinks

Third: In the ADMIN5 station Webmaster network submission, 2 articles to explore whether the net link for high-quality links and explore whether the interactive encyclopedia for high-quality links

Reason analysis: Through the video website to obtain the link is the pure text link, the author inquires these links, has been indexed by the search engine, although not as much as the webmaster Net collects and reproduces, but the author thought the link of the video website should be regarded as a better link. Webmaster Network in the Admin5 2 articles to get the majority of friends like and reprint, brought a lot of links, but also the quality is relatively high.

Analysis of the reason of the outside chain decline

First: The quality of the outer chain is low

Now the quality of the link is not good to do, the source of the site's backlinks is too single, and the source of the chain is everyone can do the link, the chain is to win by quantity, rather than winning by quality, we all know that a high-quality link than n a low quality link more effective, High-quality links to reduce the search engine on the previous low quality of the chain to crawl (since there are high-quality links, but also what low quality links do, I think the search engine should also think so, please give the search engine people's thinking), on what kind of link is high-quality links, I will be in the near future to share with you the author of the definition of high-quality links. I hope everyone in the establishment of the chain when the quality can be built to win, not by quantity and low quality.

Second: The content is included in the decline analysis

As a result of the search engine stopped the low quality of the chain of crawl, then reduce the search engine spiders to link the content of the page to crawl, such words, will reduce the search engine on the Site content page to crawl times, nature also reduced the site related pages included.

The author of the site backlinks and the content of the site included analysis, only limited to their own website analysis, if your site's reverse link and the site included a sudden drop, please analyze and analyze what happened to the site before you do something to the right remedy (except for Black Hat seo), this article has HTTP ://www.eurocrane.com.cn/first Admin5, reproduced please keep the address, the author will soon share with you, if through the video site optimization to the site to bring external links and what is a high-quality link, I hope everyone likes, this month's starting AMDIN5, reprint please keep the address, thank you.
