The impact of server security on Web search engine rankings

Site in search engine rankings, for the site is very important. But many factors will affect the ranking of the site, such as the quality of the site content, the stability of the space server, server security, and so on, if you want to have a good site rankings, to do a lot of work. This article, the author from the personal experience, speaking about server security for http://www.aliyun.com/zixun/aggregation/8612.html "> site ranking impact, Remind your friends to avoid the impact of server security problems on Web site optimization.


　　


Server attack site search engine rankings, included down


　　


May, I took over the company's website, the company's website has always been in the major search engine rankings are good. In the days I took over, the relevant keywords in Baidu Home can also be seen. However, there are accidents, August 9, the company's server was violently attacked, because this time the other party deliberately, to do their best, resulting in three consecutive days of the company's Web site inaccessible. In the parties, three days after the resumption of access to the site, but still often appear open, slow problem.


　　


in the Webmaster tools to find the site in the Baidu rankings have no, in the first three pages can not find any information, snapshots also stay on the day of attack, included a lot of decline, from Baidu over the flow of almost no. This attack really brought a great impact on the site, but also brought us a lot of work.


　　


Next is to see if the server is vulnerable, whether it was implanted Trojan program, modify the content of tampered (fortunately tampered with the data is not much), the site to find out whether the site was hung black chain, hung horse, etc., is very burned.


　　


ensure the safe operation of the server


　　


period, I consulted a number of people in the industry, they said that the server security, Web site security on the site ranking impact is very large, the site was hung Trojan or virus, Site page was modified, server paralysis, the site can not be normal operation and so on will affect the ranking of the site.


　　


especially such as we have encountered a serious attack, on the one hand, clean up the end of a short period of time, redo the safety work time-consuming, on the other hand dropped the site rankings after a good period of time to fully return to normal.


　　


with this experience, my personal experience is that the treatment of Web site security is like treating your own health-prevention is important. Kung Fu should be spent on daily prevention, so that the attack cannot enter. The installation of the protection software on the server to be installed not lazy, regular monitoring and monitoring, the inspection, the scan scan, the threat of eradication in the embryonic state. Because usually it is okay, in case there is a problem, it will take several times the energy to solve.


　　


Experience Summary


　　


this time, the server was attacked, caused us a lot of damage, here to talk about our approach to share with you:


　　


1, modify the server's account password information. We suggest that you must set the password more complex.


　　


2, scan the server. I'm using a security dog, which has an optimization function to check the server for vulnerabilities. If it is found that there are loopholes, it is recommended to repair in time, patched, so as not to be exploited by hackers.


　　


3, usually use security software of the network horse scanning function, check the security of the site, such as whether the horse is hung, black chain, etc.


　　


4, often pay attention to the server, Web site traffic. If the traffic found abnormal, to timely processing.


　　


5, attention to log information. After we installed the security dog, we often go to check the protection log information, through the log, you can analyze a lot of problems.


　　


6, in addition, if installed the website safe Dog, must pay attention to the search engine IP to join the Safe dog White list, joins, when has the spider to visit the website, may unimpeded, otherwise also will affect collects, remember.


　　


7, completes the database, the website backup work. This time, although the content is not much tampered with, but still spent a little time to repair, pain (this feeling that regular backups are necessary). Therefore, we suggest that we should do a good job of data backup.


　　


Also, be careful to check your server system account for suspicious accounts, especially those with high privileges.


　　


through a series of work, August 26, the site included, snapshots, search keyword rankings finally returned to normal. Finally, you should also pay attention to the content of the site update.


　　


above is the author of some of the shallow experience of the point of view, experienced this toss, but also received some gains. Now installed a safe dog (also can choose other server security software), regular inspection scan, one months passed, the server, the site has not been attacked (basic interception), ranking is also stable. Small experience hope to share with you, servers, Web site security work to do in the day-to-day, in order to prevent the prevention, and optimize the site to complement each other, continue to upgrade the site rankings.
