The website is hacked, which means that the security factor of the website is low. Generally speaking, there are many loopholes in the site program, such as BUG, or the password setting of the site management background is too simple.

In today's website construction, some open source CMS systems are generally used, such as PHPCMS system, DEDECMS system, Imperial CMS system and so on. Open source system should be simple, convenient and fast in website construction, but if it is not very good for secondary development, there should be a lot of BUG. In the process of operation, the website is easy to be blacklinked by some all-pervasive grey industry sites.

If in the usual maintenance work, using iis7 website monitoring to check the security of the website in real time, the problem of hanging black chain can be found as soon as possible, and the remedy is still very simple after discovery, so we must do the inspection work diligently.

I remember that this is the case with a site optimized by Yang Zi in 2013, when the site was built with a certain CMS, and Yang Zi did not comment on the cms system for an unskilled male born.

Let's get back to business and talk about how to judge whether a website has been blacklinked! Baidu search box uses the command: domain

When analyzing whether the website has been hacked, you can enter the outer chain query command domain+ home page url, such as domain:www.xxxx.com, into the Baidu search box. The site is an aso optimized site. When using the outer chain query command for analysis, it is found that a title is "Dafa 888 deposit [network discount] Dafa 888 deposit". Its Description also contains some keywords that are not related to the site, such as: "xxx is the first professional company in China."

If the above situation is found, it is enough to show that the site has been hit by some grey industry websites. Second, click on Baidu snapshot for further analysis

Click on Baidu snapshot to enter, pull down will see a lot of such × × film, a website to do ASO there are so many irrelevant sexy beauty pictures, this must be a problem.

Next, if you continue to pull down to the bottom, you will find a lot of anchor text from the grey industry.

Anchor text like the image above is generally hidden at the front end and can only be found in the source code. Check the source code of the website

Or stay in the Baidu snapshot page, click the right mouse button to view the source code

From looking at the source code, we can see that there are all kinds of grey industry links, of course, now that we have found the root cause of the disease, it is much easier to deal with it.
