This article mainly introduces the web development site encountered snapshot hijacking how to do, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

What is snapshot hijacking? Snapshot hijacking is that the page crawled by Baidu is a normal page, through search keywords, the jump when visiting is indeed a completely different site crawled by another website and search engine. After the website is opened, it is an illegal gray website, some words search and display is normal, some words open have no effect at all. In fact, these are the so-called website snapshot hijacking.

A few days ago, a friend gave me feedback on a question, saying that his website ranking suddenly lost all keyword rankings in a few days. Let me help you analyze if there is something wrong with the optimization. My friend sent me the URL I did not directly open but SITE, found that the collection is normal, and then clicked on an included page, and found that the page information is all gray gambling information. I gave him feedback on this problem, and he said that he did not find this. After several exchanges, he found that he had been using the address to enter the URL to open the website, and it was normal every time. So it has never been found that the website has been tampered with.

The above is the most typical case of snapshot hijacking, and the title of the home page has changed. However, the expression has not been changed. In fact, such hijacking is not difficult to solve, we can look at the code of the main page of the site to determine how to deal with it.

Through the code, we find that the web page is obviously modified into two headings, the title opened by the normal URL is the title of the site itself, and the snapshot title is written by code, so most people basically can't see what the code is writing. only search engines can judge these strings. There is an extra JS code, needless to say that this code is to judge whether you enter the website through the URL or through the snapshot.

To find these basically solutions have come out. That is to delete the code and the site can be restored. Then if the ranking is restored, you can try to go to Baidu Snapshot to complain about it. There may not be unexpected gains.

So the question is, how to prevent snapshots from being hijacked? To learn to prevent snapshots from being hijacked, you must know how hackers hijack your snapshots.

Note: most of the snapshots are hijacked by hackers who tamper with the source files of your website pages through your FTP (right where you put your programs in FTP) to achieve the purpose of hijacking snapshots, so the security of the web space server is particularly important. The FTP password is updated irregularly, and the setting is as complex as possible. Don't tell strangers. The server generally chooses a reliable host with security protection. If these things like this can be done, it will basically not happen again.
