We will never know or know the search engine's algorithm, but we can clearly realize and perceive that because of our seoer, the search engine becomes more and more sensitive. So that you can get your site from heaven to Hell in one night. Then, as a once suffered from the seoer of Baidu, summed up some of the favorable suggestions for everyone to reference, especially novice friends.
Keyword density, I am referring to the idea of a serious departure from the user experience or paranoia to accumulate a large number of related keywords in the keywords and description areas of meta to increase exposure. Whether you are at the top of the page, bottom or any other part of the accumulation of a large number of keywords, these are futile, search engine focus on the user experience, she will not be a user experience can not talk about the page presented to the user, the serious circumstances will be punished! Secondly, The weight of the keywords and description areas in the meta area has been greatly reduced, and the effect is negligible. Also do not accumulate keywords, keywords area you can basically see her does not exist, and description is the search engine results page directly presented to the user's intuitive feelings. Similarly you must pay attention to the user experience, the brand image!
Second, hidden text, the use of hidden means to place a lot of text and links on the Web page, the viewer can not see hidden text and search engines to crawl, and thus deceive the search engine on the Web page keyword judgments. The usual trick is to set the color of text and links to the same background, after the text is placed in the picture, use CSS to hide the text, such as: Font size set to 0, hidden links through CSS, such as: linked to 1 pixels, the link hidden in the small characters, such as: comma ..., cheating methods emerge. Here to advise you webmaster, with the proliferation of cheating, search engines have begun to strictly control this behavior. Advise you webmaster don't defy the odds ~ ~ ~
Cross-connect or join a link factory some webmaster hand some site because of PR or other reasons and difficult to find friends chain, so that is to use their own a station to do others B station of the single chain, and then let others use B station to their own C station single chain, in order to promote the development of new stations. Or even more, directly joined the link factory, each search engine is very opposed to two practices, and has been able to identify the two link structure, so remind the major webmaster attention.
Four, the black chain, the recent blog webmaster message said to do outside the chain is very difficult, very annoying. I mean, what's the point of the algorithm if you can easily get a high quality chain? What is the quality of the rankings? Usually we get outside the chain can use soft grammar, the major web site message comments, forum personality signature, blog group Building, landing major navigation stations and many other methods. Some webmaster for the map, efficiency, choose to buy black chain (the so-called black chain refers to some hackers after taking the station, in the page to add hidden code, forming the effect of the chain). Now the search engine is also tough against this improper way to get outside the chain, and Google now has several ways to detect the black chain.
Five, cloaking: In order to improve the ranking in search engines, not natural to a large number of input keywords to the Web page, so that it does not show to ordinary users, only selectively sent to the search engine a method. If you use the bridge page, in the early days some webmaster by building a full range of popular Keywords page, to get a good ranking. And after the user clicks on the page, jump directly to other pages. Most search engines, however, regard this as an improper behavior, punishing the site for cloaking to exclude it from the catalogue, or drastically reducing the rankings. Because the search engine only through the itinerant robot does not know whether the website uses the cloaking, therefore the general to not naturally arranges to the list front website to take the artificial examination and so on the countermeasure.
