Among the search engine optimists, the use of cheating techniques is referred to as the black hat seo, and the use of conventional means consistent with the 100-degree seo proposal is referred to as the white hat seo. The main feature of the black hat seo surplus capacity is a short and fast-track scheme for short-term benefits. While the black hat seo technology can provide a certain amount of user size and ranking, once discovered by the search engine, it tends to end up being k, and once the website is k, it takes about three to six months for its recovery cycle, which can be said to be very long。
Black hat seo
1. Spider hijacking
Spider-kidnapping is not what everyone says, hacking someone's website, jumping, then hijacking traffic. It's traffic-kidnapping, not spider-kidnapping. Real spider-kidnapping can make users and search engines see different pages. Users, for example, see parts of friendship links, while spiders do not see modules of friendship links on the site。
Hide pages
Whether the hidden page is a search engine or an ordinary user that uses a program or a foot. 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。
3. Domain bombing
A newcomer to seo tends to believe that many domain names are registered and linked to the main station to enhance the main station's pr! If these domain names have their own website, there is 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
Four, black chain
Scans the ftp or weak server code, sews, then cracks the site and hangs the link. This is an illegal method. But these can be found through the seoquake plugin。
5. Garbage links
Joining a large number of linking mechanisms means a network system consisting of a large number of web-page cross-links, which, once detected by a search engine, are likely to be at k-stations. It is to be hoped that the seoers, when optimising at normal times, will be aware of the existence of such cheating methods, will be able to improve search sequences, attract hits, repeat keywords, publish numerous links to unrelated content in blogs and forums, collectively known as garbage links。
6, 301 reoriented
301 is a state code in the http site, and 301 in the search engine is directly capable of delivering weights, which can be obtained when a large number of, and large number of, websites have 301 to one page。
7. Pay links
The purchase and sale of links is strictly prohibited in search engines such as 100 degrees. They stated on their website that “any link or ranking of the site in 100-degree search results aimed at manipulating pagerank may be considered as part of the linkage programme and contrary to the 100-degree webmaster guide”. This includes sending free products from websites in exchange for links。
8. Invisible text and links
In order to increase the frequency of occurrence of keywords, a text containing dense keywords of the same colour as the background is deliberately placed on the web page. Visitors could not see, but the search engine could be found. Similar methods include super-small text, text hiding layers, etc. This is one of the more common reasons why websites are being reduced, and many of them are not self-inflicted, but are secretly added to you by someone who sells a black chain, which is to make the station chief more aware of the need to guard。
