There is no precise definition of white hat seo or black hat seo. Generally speaking, anyone who uses deception or some suspicious means can be called black hat SEO. For example, hidden web pages, keyword stacks, spam links, door pages and so on.

Black hat SEO can quickly bring a certain number of rankings and users, but it is often the result of K. Once it is K, it will take at least half a year to recover. Second, it is not a good result for the brand.

Deception trick

Expanding external links is not necessarily by exchanging friendly links. There are many places to get external links. For example: blog comments, online comments, guest books, forums and so on. In blog comments, online comments, guest books, forums and other places, you can often see the wonderful works of black hat SEO. Below, introduce some common link cheating tricks of black hat SEO:

1. Blog cheating

Blog is a very interactive tool. In recent years, the rise of blogs has become a blessed place for black hat SEO to create new links.

2. Bloggers cheat: Some common domestic blogging programs, such as wordpress, ZBLOG, PJBLOG and Bo-blog. The early ZBLOG and PJBLOG were due to the developers' ignorance of SEO. ZBLOG and PJBLOG used to be frequented by black hat SEO people. However, the Bo-blog blog project still seems to give Black Hat SEO a chance.

2. Blog cheating: Blog cheating is to apply for a large number of blog accounts through procedures or artificial means. Then by publishing some articles with keyword links, these links can promote the search engine ranking of keywords.

3. Blog hidden link cheating: Cheaters improve the ranking of search engines by providing free blog templates, adding hidden links in style files and increasing hidden links of websites.

Page jump

Using Javascript or other technologies, users can quickly jump to another page after arriving at the page.

Steal pages

This is a highly optimized web page designed for SEO. When the website gets an ideal ranking, it will replace the optimized page with a normal page.

Doorway page

Make an optimized page specifically for a keyword, and point or redirect the link to the target page. Moreover, the door page has no actual content, just piling up keywords for search engines. [3]

Group sending guest book

Group software can use the guest book to automatically publish its own keyword URL, and quickly improve external links in a short time.

Link factory

"Link factory" (also known as "mass link mechanism") refers to a network system formed by a large number of web pages. These web pages may come from the same domain or multiple different domains, and may even come from different servers. After the website joins such a "link factory", on the one hand, it can get all the links in the system, and in exchange, it needs to "dedicate" its own links, so as to improve the link score and achieve the purpose of interfering with the link score.

Hide link

Hidden links are generally used by SEO on customer websites, using hidden links on their own customer websites to connect their own websites or those of other customers.

False link

Add a link to a JS code, frame or form. Links in this way cannot be read by spiders in search engines at all. So links are just for people to see, and search engines can't recognize them at all.

Webpage hijacking

Web hijacking, which we often say, is to copy the content of other people's websites or the whole website and put it on your own website. This black hat SEO method is very attractive to webmasters who are extremely short of web content. However, this practice is quite risky and even more shameful. The patented technology of search engine can judge from many factors that the copied webpage or website is not original and will not be included.

Website mirror image

By copying the content of the whole website or part of the webpage and distributing it to different domain names and servers, the search engine is tricked into indexing the same website or the same page many times. This is why some websites indicate that it is forbidden to mirror websites without authorization. The two websites are exactly the same, and too high similarity will inevitably affect their own websites. [4]

Address redirection

302 Redirect: 302 represents temporary movement. In the past few years, many black hat SEO have widely used this technology to cheat, and major search engines have intensified their efforts. Even if the website is not spam objectively, it is easy to be misjudged as spam by search engines and punished. Everyone must have had this experience. When you search a website, you will become another website. This is mainly achieved by jumping technology, and you often jump to a profitable page.

Hang a black chain

Scan FTP or server for weak passwords and vulnerabilities, then hack the website and put links in it. This is illegal means, and these SEOer are also my contempt. There are many such people in China. These can be found with the help of SeoQuake plug-ins.

Crown method

Simply speaking, masking means that the webmaster uses two different pages to achieve the best effect. One version is only for search engines, and the other is for yourself. Search engines say this is illegal, if the version of the website provided to the search engine can't truly reflect the real content contained in the webpage. If found, the website will be permanently deleted from the list of search engines.

Keyword filling

Many webmasters have accumulated a large number of keywords when optimizing keywords, which makes search engines think that web pages are relevant. Keyword accumulation technology uses a long list of repeated keywords to confuse search engines. In fact, these keywords are sometimes related to the content of the web page, and sometimes they have nothing to do with the content of the web page. This method rarely works, and it is unlikely to drive the ranking of a website to a higher level in a long time or a short time.

Public relations hijacking

The method of PR hijacking is to jump. Generally, when dealing with the turning point of 30 1 and 302, the search engine will regard the target URL as the URL that should actually be included. Of course, there are exceptions, but in most cases, this is how it is handled. So if you jump from A domain to B domain 30 1 or 302, the PR value of B domain is relatively high, and A domain will also display the updated PR value of B domain. The easiest way is to jump to the domain name B with high PR by doing 30 1 or 302, and immediately cancel the turn after PR update, and get the same PR value as the mile. This false PR display value will be maintained at least until the next PR update.

Subtle words

Many people who do search engine optimization know that hidden words may be punished, so they expose hidden words with fine fonts. Subtle words even use tiny fonts to write sentences with keywords in inconspicuous places on the web page. Generally speaking, these words are placed at the top or bottom of a web page. Although the colors of these characters are different from those of hidden characters, they often appear in very similar colors.

Hide page

A hidden page is a webpage that uses programs or scripts to detect whether it is a search engine or an ordinary user. If it is a search engine, the webpage will return the optimized webpage version. If the visitor is an ordinary person, return another version. This kind of deception is usually imperceptible to users. Because once your browser looks at this web page, whether it is on the page or in the HTML source file, you get a different version from what the search engine sees. The way to detect it is to take a look at the snapshot of this webpage.

hidden text

Hiding words means putting words containing keywords in an HTML file of a web page, but these words are invisible to users and can only be seen by search engines. There can be several forms, such as ultra-small font size text, text with the same color as the background, text placed in comment tags, text placed in table input tags, text placed on the invisible layer through style sheets, and so on.

Doorway page

Doorway page [3] usually uses software to automatically generate a large number of web pages containing keywords, and then automatically turn to the home page from these web pages. The purpose is to hope that the front page for different keywords can get a good ranking in search engines. When users click on the search results, they will automatically go to the home page. Sometimes you put a link on the home page instead of opening it automatically.
