Some time ago I have to do a station, ranking long-term first, every day there are views, articles, the chain also updated every day, but a few days to find a lot less traffic, went to see the next log, found that users click on a page will jump directly to other sites, this site and my site or the same industry, an instant fire, Because there have been attacks before, so immediately think is someone malicious change My site code, is a kind of SEO attack means, my site is more commonly used DEDECMS management system, these commonly used management systems are often many loopholes, many people know, I usually do not pay attention to patching a kind of thing, the result accidentally was shot.

I've had similar experiences before, so found the problem, I immediately see the first source file code, no jump code, see the JS code also nothing to see, look at the FTP user password is no problem, it seems to sabotage that person did not do too absolutely, not in the site to tamper with other parts, I went straight to the page to be jumped, Look at the code, found a section of the encoded JS, and then in the database to find a corresponding table, download and restore the database, and then replace the code, the last site back to normal. Of course this is not enough, to know that the site is now normal, but inevitably behind someone, so I can't just relax, find someone else to the site of the Trojan Horse and back, the DEDECMS upgrade to the latest version, and then to the site to play the latest patches, this can be more thorough to prevent the fall of things happen again.

Say such a thing just want to say SEO to do is the traffic of the website, ranking, conversion rate do well, and do these will generally have a lot of competitors, high-quality competitors will use the normal way to fight with you, at most, imitate our site update methods and layout, and then summed up some of their own characteristics to fight with us, However, if you encounter some of the people who are rather bad, a little more ruthless, might use improper means to attack our website.

Now the network is more and more developed and popular, some of the more simple hacker technology online to find some estimates, and there are many SEO thugs, specifically for the ranking of good sites to attack, especially some popular words, the interest is relatively high, you block others Rich Road, attack your site is not surprising. Like this thing that I've met is relatively simple, damage not too much of an attack, also relatively easy to find, and they often use the means of various, impossible, some are difficult to find, and eventually led to the site down the right or inaccessible, the site and our own interests hurt very much, so we have to be careful of the dike. Let me tell you about some SEO attacks and personal precautions I've learned.

One, as I encountered this, the use of Web site vulnerabilities, the site code or files to modify, thereby damaging the interests of the site, such as shielding spiders, Tampering with ROBOT.TXT files, etc., in the event of such things, as long as the usual attention to the development of the site, in the event of a problem, can quickly respond to, and then find the problem is relatively simple, no harm, modification is not difficult.

Second, DDoS attack, is also a previous attack I encountered, belong to the hacker technology, because the previous understanding of relatively few, I that site was wildly attacked, so that the server is in a state of paralysis, unable to visit, several days passed, and my site has been down the right, and then recovered to spend 1 months of time. DDoS translations are called distributed denial of service attacks, is a lot of Dos attacks on a server together to form a DDoS attack, Dos attacks in many ways, the most basic Dos attack is to use a reasonable service request to occupy too much service resources, so that the server can not handle legitimate user instructions.

Third, there is the search engine, and now the domestic search engine technology is not perfect, for some malicious damage can not be clearly judged, easy to appear manslaughter.

1, others use 301 jump to some spam sites or pornographic sites to jump our site, search engine is easy to misunderstand our site, jump the number of sites more points, may lead to our site down right.

2, to our website brush flow, sound is not feel that there is a problem, brush flow better ah, but if the site traffic suddenly rose, it is easy to cause search engine attention, will feel that the site has cheated, leading to the right or lower ranking.

3, the site frequently submitted to the search engine, we all know, in general, we will be in the early days of the website submitted to the search engine, to attract the attention of search engines, to enhance the speed included, but if frequently submitted to the search engine, so that the search engine frequently run, and the site did not update, it is easy to make a bad impression of A large number of submissions may also result in a reduction of power.

4, in the site outside the chain of a large number of comments spam.

Four, write some posts in the large forums and blogs, the content is to pretend to be in our website consumption of customers, and then talk about some of the site's bad or derogatory website products, thereby affecting the site's brand benefits and reputation. This before I have met, can only be sent to the bad post to press down or find a forum moderator to delete the post.

Five, to the site to hang a horse, so that the site will often pop up some ads, and the search engine this year to update the algorithm, the punishment of such sites is very large, it is likely to drop the right, so find out in time to find the site's bad code, to delete.

The last thing to say is that at home, for their own benefit, so dry people still have a part of, so usually to the site for backup, encounter unexpected events will not be unprepared, I have not bothered to back up, and then hung a number of stations, these stations only in the early days of the site backup, and then did not back up, and then spread up, Articles what are less than N, customers open URLs are often 404 pages, and included a substantial decline, very tragic. So backups are necessary and often backed up. Also need to pay more attention to their own website, especially ranked first, second website, in case of being black.
