Recently, many customers have asked that their websites suddenly disappeared from Baidu or Google. They were well included in the past, but now not even one page is included. In this case, 95% of the time it is possible that your website has been hacked. Today I want to talk about how to know whether a website has been hacked. Please see the analysis below.
If your site is newly built, many website managers may initially exchange friendly links. Before making a connection, you must check to see if the target site to be linked has been punished by search engines. In other words, It is K, especially whether it is K by Google or Baidu. Because after a domain name is K, even if it changes its name, it may not be effectively included by search engines for a long time. Therefore, many companies have built a good website. Don’t blindly optimize it yourself. You must find a professional person or company to optimize it.
There are roughly the following query methods for reference. Here's how:
The first method is to use the two search commands site: / link: to check the inclusion of the domain name. If the inclusion is 0, but there are many external links, the domain name has been K.
The second method is to directly enter the website address in the search engine to query. If you find that several results contain the domain name completely, and the site does not have it, then the domain name is most likely to have been K. (It is impossible that the search engine did not immediately publish it in the search results after indexing it.)
Type 3: Determine whether the domain name is an old domain name by checking the website history page, website world ranking, etc.
Many websites rely on Baidu for traffic, but everyone knows that Baidu K station is famous. I bought a domain name and worked hard to build a website, but it was not indexed by Baidu. Finally, I found out that it was a domain name that had been deleted. So let me teach you how to check whether a domain name has been used as a website and whether it has been K-passed.
1. Check whether the domain name has been used as a website <most suitable for purchasing second-hand domain names>
Open http://web.archive.org/web/, enter the domain name you want to query and press Take Me Back.
If you create a website, the data will be displayed.
2. Whether the domain name has been K-passed
Open Baidu and enter domain:***.com in the Baidu search bar.
If there is a record, but there is no record when using site:***.com, it means that the domain name has been K.
