Hide link
Hidden links are generally used by seos on client websites, linking their own or other clients ' websites by using hidden links on their own client websites。
Fake link
Adds a link to a js code, frame or form. The link in this way is simply not accessible to spiders in the search engine. As a result, the links are only visible and the search engine is simply not identifiable。
Web hijacking
The web hijacking, which we often call page jacking, is the complete copying of someone else's website content or the entire site, stealing the beams for their own website. This black hat seo method is attractive to station chiefs who have a very limited web content. However, this approach is rather risky and shameful. The patent technology of the search engine allows multiple factors to judge that the duplicated web page or site is not original and is not recorded。
Website mirror
The multiple indexing of the same site or page by the search engine by copying the entire site or part of the web page and assigning different domain names and servers is both the reason why some websites state that they are not authorized to mirror the site, and that similar heights inevitably affect their own websites。
Redirect address
302 redirect: 302 represents a temporary transfer. In previous years, a number of black hat seos have extensively applied this technology, and major search engines have intensified their efforts. Even if the site is not objectively spam, it is easy to be punished for being miscalculated as spam by the search engine. It is certain that you have a history of searching one site and entering it into another, mainly through leapfrogging technology, which tends to jump to a profitable page。
Black chain
Scan the ftp or server weak passwords, loopholes, then hack the website and put the links in. It's illegal. I despise these seoers, and there's a lot of them in the country. These can be found through the seoquake plugin。
Pomponphate
In short, the webmaster uses two different versions of the page to optimize the impact of the cappuccino. One for the search engine only, one for yourself. The search engine stated that such practices were illegal, if the website version provided to the search engine did not accurately reflect the true content of the page. If found, the site would be permanently removed from the search engine list。
Keyword stack
Many station chiefs, in optimising keywords, piled up a large number of keywords, making the search engine think web pages are relevant, and the keyword accumulation technique uses a long list of repetitive keywords to confuse search engines. In practice, these keywords are sometimes related to web content and sometimes to web content. Such approaches rarely work, and it is unlikely that a website will be ranked high in the long or short term。
Pr hijacking
Pr's method of hijacking is to use jumps. The general search engine handles the transition between 301 and 302 using the target url as the actual url to be recorded. There are, of course, exceptions, but in most cases this is the case. So if you jump from domain a to domain b by 301 or 302, then domain b has a higher pr value, and domain a is updated with a pr value for domain b. The simplest is to jump 301 or 302 to high pr domain name b, which is cancelled as soon as the pr has been updated, and to obtain the same pr value as station b. This fake pr display is maintained until at least the next pr update。
Fine text
Many people who optimize the search engine understand that hidden text may be punished, so they reveal the hidden text in fine fonts. Minor text even uses small fonts to write sentences with keywords where the web page is not visible. These are generally at the top or the bottom of the web page. The colours of these texts are not the same as those of hidden text, but they often appear in very similar colours。
Hide page
Hides whether the page (claked page) has a program to use the page or a foot to detect whether it is a search engine or an ordinary user. In the case of a search engine, the page returns an optimized version of the page. If the visitors were ordinary people, another version was returned. This form of cheating is usually undetectable to users. Because once your browser looks at the web page, whether on the page or in the HTML source file, you already get a different version than the search engine sees. The test is to look at a snapshot of the page。
Hide text
Hidden text (hidden text) is the text containing keywords in the HTML file on the web page, but they cannot be seen by the user, but only by the search engine. There are several formats, such as text with super-small fonts, text with the same colour as the background, text in the comment label, text in the input tab in the table, text on invisible layers through style sheets, etc。
Bridge page
Bridgeway pages are often automatically generated by software with a large number of web pages containing keywords and then automatically shift from those pages to the home page. The aim is to have these bridge pages, which target different keywords, ranked well in the search engine. When the user clicks on the search result, it automatically transfers to the home page. Sometimes, a link to the home page is placed on the bridge page and not automatically turned。
The first type of technical editing, a keyword stack, is the most commonly used technique。
Many people, while optimising keywords, stacked keywords for only one purpose, just to increase the frequency of occurrence of keywords, increase the density of keywords and force them into web code, mEta label, title (especially this), note, repeats a key word in a picture alt, making it very dense, but it will work well if it is not discovered。

Second, redirect。
It's a way to use refreshing tagsEtarefresh and java and js technology. When a user enters a page, using these features, he jumps quickly to another page, so that re-direction does not align the search engine with the page that the user is accessing. It is important to note that this author once had a site that had been downgraded for a long time。

Third, domain-name bombing。
Newcomers like seo tend to think that there are many domain names registered and linked to the main station to enhance the main station's pr! If these domain names have their own website, there's no problem! But if these domain names have very little content, or point to a page in the main station, the search engine will think it's cheating!

Fourth, too many false keywords。
Many sites will add many key words that are not relevant to the station to their own website, by mIt is a less formal way to optimise the entry of search engines and users by setting in eta keywords that are totally irrelevant to the content of the website, but the author speaks of too many false keywords and changes the web page to add this keyword, which is likely to result in a reduced ranking of penalties (the latter is more severe)。
