When a website is hacked, it is a real heartache for the webmaster. A lot of hard work has been put into the website. Just because a website has been hacked does not mean that it is over. Based on the experience of major webmasters that I know, let’s analyze a website that has been hacked. How to save it?
First of all, don't be anxious, because there is no point in being anxious. First, carefully check the content of the website, recall what modifications were made before being Ked, and whether any illegal information was added. If you haven't made any modifications before, or you just modified some innocuous things, then there are two possibilities. First, it may be that your website links to some illegal websites that have been hacked. If this is the case, just remove the links to the illegal websites and it will return to normal in 1-2 weeks. Note that the website should not make major changes during this period. It should continue to be updated daily and appropriately add some high-quality links (which will bring benefits to you). The second possibility is that a certain site on the server where the website is located has been hacked, and innocent people are implicated. In this case, you should first investigate whether the collection of other IP addresses on your server is normal. If the investigation results fall into this situation, you should contact the server supplier and request to change the server. It is best to change to a more stable server.
If the website has been hacked because of a small amount of modifications to the content, and the hack is not very serious, first remove the illegal or cheating information (as for illegal information and cheating methods, there is a lot of information in major webmaster forums, so I won’t cover it here. (Repeated description); Reduce the keyword density of the website, which was previously around 5%; and then optimize the website content (original or pseudo-original depends on what you are good at) and optimize the content title, such as adding 'new', 'Activities', 'surprises'... (depend on the specific situation, don't add them randomly). Update the content in a timely manner, so that new content appears every day to increase the activity of the website; appropriately add some high-quality links (which will bring you benefits), and finally, go to some major sites, forums, etc. to post some original works article and add your link appropriately. This kind of K is a warning. As long as you do your job well, it will usually return to normal after a while. If the K is severe, then you need to make corresponding major changes, which is equivalent to changing your mind and re-doing your station. You should not give up at this time. As long as you can learn from failure, failure is the mother of success. With this experience, I believe you will do better.
If a website is K because the main content has been significantly changed, as long as there is no cheating or illegal content, it is generally considered to have been temporarily downgraded. The search engine will need to re-analyze the website. At this time, it will depend on the changes made by the webmaster. Once you are determined, change is painful (being demoted), but you may be more successful after the change. The power reduction is temporary. As long as you work hard to build a good website and retain customers, search engines will definitely recognize your efforts.
