Nowadays, most webmasters are thinking about how to build external links, how to publish website content, and how to get their website to the homepage or the top three. In fact, behind the glamour, website security actually requires webmasters to pay attention. Because once there is a problem with website security, the ranking of the website will also be greatly affected. Below, the author will carefully analyze several phenomena related to website security and how to deal with them.
The first type: the website is linked to a "black link"
Even if Baidu does not update its algorithm, as long as it encounters a black link on a website, the website will definitely die, and there is no other possibility. This is much worse than using cheating methods to improve keyword rankings, but it is not impossible to prevent the website from being linked to black links. As long as the website is being maintained, regularly check the source code of the website and use the "website dead link detection" of webmaster tools. 'Function', often change the user name and password of the website ftp and then check the modification time of the file on a regular basis. This can definitely effectively prevent the website from being linked to black links.
Second type: The website opens slowly
Spiders have an inspection period for websites. During this inspection period, they will crawl the website content from time to time. If the website opens very slowly during peak periods or cannot be opened, it will lose the trust and favor of the spider. In the long run, the spider will come to The number of visits to our website will be even less, and the ranking is probably not ideal either. However, there is still a solution to this problem. First, we check the stability of our server to see if there is a problem there. Secondly, we also need to check whether our website has been attacked by other websites, because once it is attacked It is inevitable that the website cannot be opened due to attacks by others. Many well-known forums, such as SEOwhy, have experienced ranking fluctuations due to website attacks.
Type 3: All website data is lost
This situation also happens from time to time, so when building a website, in addition to studying how to better optimize the website, we should also pay attention to backing up the data of our website. I worked on a local forum before, but it was attacked for some unknown reason, and more than 500 replies were deleted. Later, after hard work, the website was restored, but the 500 replies were consistent with the URLs that had been included before, which caused my website to be corrupted. There are suspicions of repeated submission of content, and the ranking of the website has dropped by a thousand miles, sadly reaching outside the top 100. Therefore, you must pay attention to backing up the website data. It's okay if nothing happens, but it will be over if something goes wrong.
Type 4: Dead links or useless spam links appear on the website
Dead links are generally caused by websites posting external posts or replying to comments with links, and then being deleted by the bar owner after a period of time. If our posts or comments are obviously advertising, or the quality of the articles is not high, it will not take long. will be deleted, which is a big blow to the stability of external link construction. Spam links may mean that your own website has been attacked. Think about why hackers attack your website, isn't it for those illegal links? So when the website is unstable, you must investigate and deal with spam links and remove them in time, otherwise Endless troubles!
Type 5: The website title is modified
This happens all the time, but it's all done by unscrupulous hackers, usually competitors. Their purpose is to invade our website and then mess with us in areas that can easily lower the website's weight, such as website programs, Things like the website title will be modified frequently, causing our website to be demoted or punished. The preventive measures are similar to the first one. Check the source code of the website regularly to nip it in the bud.
After reading the above five items, webmasters are a little frightened. Just like the old saying that a thousand-mile embankment is destroyed by an ant nest, they do not pay attention to these small details and only care about website rankings every day. The first thing is the site website. If we don’t pay attention to website security, sooner or later we will be unable to take measures! However, as long as everyone maintains the website well on weekdays, we can solve these problems.
1. Choose a safe host provider. However, after choosing a host provider, we must always check other users of the host and see the situation of their websites. After all, if they are punished, we will also be implicated.
2 Choose a safe website program. Nowadays, CMS is the industry consensus, but when choosing CMS, you must choose a mainstream program, because when security vulnerabilities are discovered, you can keep up with the official website and patch them in time.
3. The website must be md5 encrypted, because when using a mainstream CMS, the possibility of communication will be increased, so the website must be encrypted at this time. When it is not needed, even me and the member login can be omitted.
4 Pay attention to system leaks, website template loopholes, website program loopholes, and try not to use third-party plug-ins. In addition, I believe I don’t need to go into details about the necessity of anti-virus software.
If there is a problem, deal with it, and if there is no problem, prevent it. With a two-pronged approach, website security will definitely no longer be a "stumbling block" to the progress of the website!
