Case study: The cause of the steep drop in website rankings

A lot of webmaster friends will encounter not easy to do up the keyword ranking drop or disappear, a moment will feel very flustered, also do not know which link appeared in the problem, or encountered this situation, unable to find a solution, every day in the forum to ask this question, The results of the answer is not irrigation, or is always said the content of the king, the chain for the emperor, the basic is more unified, look tired, not too much practical help, and finally rely on their own. Because the author is this way, but also experienced a large and small seo difficulties, but today I face this situation is extremely calm, because do not have experienced this situation webmaster, not a qualified webmaster, is also unable to grow the webmaster.

The author from their own operating a QQ class station to analyze the reasons for the decline in the rankings, first of all, the situation of this site, as shown:

　　

Small station since 2010 on the line, experienced about two years, starting from May 2012, the rankings are very ideal, the target keyword most of the first three pages in the search engine, more long tail keyword in Baidu basically all is the first place, the flow of daily brings is also very considerable. Results in late October, but there was a big reversal, the site was Baidu search engine to drop the right. The target keyword is basically in the first 50 pages of Baidu basically can't see, the long tail also disappears. After the author to reduce the right reasons, there are probably the following points.

1, server

The author uses a VPS, in order to improve the security of the VPS, the default administrator account of remote connection is modified in Group Policy, because of the error of operation, the modification failed, the Remote Desktop can not connect, consulted the IDC service provider, had to reload the system, finally added the IIS debugging website, also used most of the time, Cause the website has been not open, by a lot of friends of the link under the friendship. The other is in the normal operation of the site, another problem appeared, the website PNG picture can not show, had to turn to IDC technicians, because they saw the server in the traffic is too high, the problem did not help me solve, also do not give notice, the result of my server to suspend, resulting in the site from 9 o'clock in the evening to the next day 10 o'clock more than can not open, and was just met Baidu weekly big update.

Ps:vps in the default administrator account can be modified, but the need for strict order, we can Baidu, lest step in my footsteps.

2, Friendship Links

There are several links inside the site is also Baidu for a long time does not update the snapshot, webmaster tools inside the query, but Baidu weight is still relatively high, think of their own site is also regarded as the old site it, the first time to observe again, the results have not been checked, to the site was Baidu down right after the check links, That several sites are also seriously down the right Baidu, had to notify webmaster friends to the link to the next, and the other down the right of the site also gave. There is also a website, was also QQ station ran out of the dark horse it, target keyword ranking Baidu First, do not say we also know, and he changed when the feeling is good, and then did not carefully check his site, his inside everywhere is the window and other ads, and his website links number is also in a substantial increase, Temporary careless didn't withdraw down, now that website also was Baidu to drop right.

PS: We must regularly check the site links to the situation, real-time analysis, the link to their own disadvantage and by the search engine down the right to the link to the export of too many links and the site does not exchange, such a site for their own site is not good.

3, Content

The site was ranked good, the results want to add a few columns, in order to better improve the flow of the site, so that in the future can be a Web site revision (the site itself to the main picture, less text content), the results in addition to the column, the original site of the home page made a small change, want to import traffic into the new column to add. At that time because the site added column, the workload is also big, in the content do not very good, the content of the release is not regular, slow update, resulting in the site home page weight scattered, snapshots do not update.

4, the website program security

Small station with the DEDECMS, we all know, this CMS more loopholes, the opening of the membership registration system, every day there are a lot of registration machines to register and in the new column content published spam comment content, let people delete soft. These are not conducive to the development of the Web site factors believe that Baidu can easily identify.

PS: The use of dedecms webmaster friends, if not using the membership function as close as possible; In addition, in the form submission must be in the client and server security filtering validation; Finally, the server security permissions and Web site read and write permissions must be set to avoid being used by malicious people.

5, Baidu crackdown on the sale of link behavior

Small station has always been a real station, the chain is also manually released, there is no means of cheating, and my website is also in the introduction of Baidu to combat the sale of the link when the right to drop, also do not rule out by Baidu accidental injury, has been to Baidu Webmaster platform representations, temporarily no reply.

6, Baidu website Complaint Center

Small station in just appeared ranking and snapshot fluctuations, because of the fear of friendship links by Webmaster friends to withdraw, to more large ranking fluctuations, then to Baidu complaints Center, such as:

　　

Lack of experience at that time, if there is a problem should not be here to complain, but to make representations, this is not SB two times, from the literal meaning to know how complaints and complaints are the same, the final result is the day of the snapshot of the complaint on the day of the update, the date is also the day From November 19 to today has not updated the first snapshot of the home page, although the internal pages of snapshots updated daily, but not what I want.

After finding out a few reasons, there is a point of entry, you need to observe the best execution to solve the problem before it can work.

Written in the end, SEO is not Santian two days, is a long-term process, the future is bright, the road is tortuous. Finally wish stationmaster friends every day good mood!
