This article mainly introduces what common negative SEO methods are, which are very detailed and have certain reference value. Friends who are interested must finish reading them.

Note: it is best not to do this kind of thing, think more about how to do your own website, after all, other people's website down, yours may not go up.

What is a negative SEO?

Negative SEO means that when you can't rank your own website, you pull down a competitor's page through some, usually improper, methods, and sometimes the effect is similar to that of your own page.

The negative SEO here has nothing to do with using SEO to suppress the company's negative news (or online negative crisis public relations and reputation management on search engines).

Common negative SEO methods include:

Create a large number of spam links for competitors

Punish the target website in order to make the search engine misjudge. External links are still an important part of all search engine ranking algorithms, but all search engines do not like unnatural links and try their best to crack down on spam links. Google's penguin algorithm, Baidu's Green basket algorithm are all against link links.

Typical spam links include mass blog comments, forum messages, link farms, a large number of meaningless free blogs, and even seemingly unjunk links such as press releases, template copyright links and guest blogs are often considered unnatural.

Since spam links may lead to website punishment, some people specially create these spam links for competitors. Can search engines correctly judge that spam links are made by competitors? In most cases, there is no problem, sometimes it will be misjudged, otherwise it will not be developed to reject outside the chain tool.

Create a lot of repetitive content

Plagiarize a large number of website content, or even directly create a large number of mirror sites, so that search engines think that there is a large number of copied content on the target site.

Generally speaking, duplicate content is not a reason to be punished, there may be duplicate content inside the site due to technical reasons, and there will be normal reprinting outside the site. But if all the content of one site appears on other sites, the overall quality of the site may be affected.

Search for "SEO once a day" in Baidu or Google, and you will see dozens of full-site mirrors of my small blog. Of course, most of it is not for negative SEO me, but for someone to buy a domain name and have nothing to play with, just look like a website and try it.

Hack into competitors' websites and tamper with them.

Some hands and feet are easier to find, such as hanging a horse and hanging a black chain. Search results of websites that are hung up are often marked, and browsers will indicate risks when visiting, and there are likely to be notices in Baidu webmaster platform and Google Search Console. Be hung ordinary black chain, often look at the website to know.

Hidden a little bit, put some hidden content, hide the black chain, you have to look at the source code to find out. Or search for "site:domain+ high-interest keywords", the more high-risk and high-return words, the more people cross the bottom line to become hackers, often check their websites to see if there should be pornography, hidden diseases, private services, gambling and other content.

A little more hidden, do a cloaking, the content you get when you visit the website is different from the content crawled by the search engine, so even if you look at the source code, you may not necessarily see that it has been hacked, such as what to do when the website written a few days ago is hacked. At this point, you need to check the snapshot, or use the crawl tool in the webmaster tool.

Modifying the robots file, forbidding crawling the page, or adding a noindex tag on the page can also make the site page disappear.

Don't be naive enough to think that these bad things won't happen to you. I've seen all of the above on client websites.

Attack the target website

DDOS attacks, for example, make search engines think that the site is inaccessible. Fortunately for a short time, more than a day or two, the search engine will probably no longer display the page of this site for the benefit of its users. An attack, usually after the search engine rankings can be successfully answered, but can not be accessed in two or three days will be a problem.

Make a large number of 404 errors

Create a large number of links to pages that do not exist, resulting in a large number of 404 errors. Like repetitive content, 404 itself is frequent, the page is deleted, other webmasters write wrong URL when linking, it is normal, but a large number may also have a negative effect on the overall quality of the site.

Garbage turn

Transfer a large number of junk domain names and punished domain names to the target website. Search engine punishment can be passed, a domain name is punished, can not simply register a new domain name, the content remains the same, the old domain name to the new domain name, the old domain name punishment may be passed to the new domain name, the new domain name will be wasted, and it won't solve the problem. To solve the problem of being severely punished, we need to find out the cause of the punishment and solve it, rather than simply changing the domain name.

The transfer of punished domain names to competitors may also cause search engines to misjudge and pass on the punishment. Of course, on the other hand, if the search engine does not misjudge, it may not make the competitor's domain name stronger.
