What is negative SEO
Negative SEO refers to that when you can’t rank your website, you can pull down your competitors’ pages by some methods, usually improper methods, sometimes the effect is similar to your own page.
The negative SEO mentioned here has nothing to do with using SEO to suppress the company’s negative news (or Internet Negative crisis PR and reputation management on search engines).
Common negative SEO methods include:
Create a lot of spam links for competitors
Punish the target website with the intention of misjudging the search engine. External links are still an important part of all search engine ranking algorithms, but all search engines do not like unnatural links, and strive to crack down on spam links. Google’s Penguin algorithm and Baidu’s green basket algorithm are all attacking links.
Typical spam links include group blog comments, forum comments, link farms, a large number of meaningless free blogs, etc., and even news releases, template copyright links, guest blogs and other links that seem not too spam are often considered unnatural.
Since spam links can cause websites to be penalized, someone makes them specifically for competitors. Can search engines correctly judge whether spam links are made by competitors? In most cases, it’s no problem. Sometimes it’s misjudged, or it won’t develop tools to reject external links.
Create a lot of duplicate content
A large number of plagiarized website content, or even directly produced a large number of mirror websites, making search engines think that there are a large number of copied content in the target website.
Generally speaking, duplicate content is not a reason to be punished. There may be duplicate content inside the website due to technical reasons, and there will be normal reprint outside the website. But if all the content of a website appears in other websites, the overall quality of this website may be affected.
In Baidu or Google search “SEO every day a post”, you will see dozens of whole station mirror image of my small blog. Of course, most of them are not for negative SEO, but for someone who buys a domain name and doesn’t have anything to put, they mirror a website and try to play.
Hacking into competitors’ websites
Some hands and feet are easy to find, such as hanging a horse or a black chain. The search results of the website on which the horse is hung are often marked, and the browser will prompt that there are risks when visiting, and there are also likely to be notices in Baidu webmaster platform and Google search console. Be hanged common black chain, often look at the website to know.
Some hidden content and black chain can only be found by looking at the source code. Or search “site: domain + high interest keywords”. The more high-risk and high reward words are, the more people cross the bottom line to become hackers, and often check whether there are pornographic, hidden disease, private service, gambling and other contents on their website that should not appear.
More concealment, do a cloaking. The content you get from visiting the website is different from the content captured by the search engine, so even if you look at the source code, you don’t necessarily see that it’s blacked out, such as how to deal with the website you wrote the other day. At this time, you need to view the snapshot, or use the grab tool in the webmaster tool.
Modifying the robots file, forbidding page grabbing, or adding a Noindex label to the page can also make the website page disappear.
Don’t be naive to think that these bad things won’t happen to you. I’ve seen all of the above on the customer website.
Attack target website
For example, DDoS attacks make the search engine think that the website cannot be accessed. In a short time, it’s OK. For more than a day or two, the search engine will probably not display this website page for the benefit of its users. An attack, usually after the search engine ranking can smoothly reply, but three days two can not access will become a problem.
Make a lot of 404 errors
Create a lot of links to non-existent pages, resulting in a lot of 404 errors. Like repeated content, 404 itself often appears, the page is deleted, and other webmasters write the wrong URL when linking, which is very normal, but a large number may also have a negative effect on the overall quality of the website.
Turn a large number of spam domain names and punished domain names to the target website. Search engine punishment can be transmitted. If a domain name is punished, it can’t simply register a new domain name, the content will remain unchanged, and the old domain name will be transferred to a new domain name. The punishment of the old domain name may be transferred to a new domain name, and the new domain name will be in vain, and the problem will not be solved. 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.
Turning the punished domain name to a competitor may also cause search engines to misjudge and pass the punishment on. Of course, on the other hand, if the search engine doesn’t misjudge, it can’t make the domain name of the competitor stronger.
