Today to share with you, the common SEO cheating in the link cheat.

Hidden links

For hidden links you should be no stranger, in fact, and before the content of the article cheat has a certain similarity, hidden links refers to the normal link through some methods, such as the link into the JS code, the use of display:none, etc., so that users can not see this link when browsing the web, The search engine to crawl is able to recognize this link from the code.

Common hidden links have the following

1, use very small font, put in the place that makes people not easy to notice.

2, in the site hidden place with punctuation and other small text to do anchor text.

3, through CSS or div style= ' display:none; To achieve the purpose of hidden links.

The effect does not need to emphasize, on the one hand the search engine can identify, on the other hand no user experience, this is very dangerous practice.

Hidden Links Example:

Garbage connection

For the garbage link, is not necessarily a deliberate black hat means, but in the neglect of the quality of external chain attention. It's possible you're in the forum all the while the outside chain of the irrigation belt may have negative effect on the website.

Of course, for low quality outside the chain and the difference between the chain does not have a clear line, a small number of low quality chain, search engine will ignore the weight of the site transfer, if the low quality too much, it may be judged as a garbage outside the chain, will have a negative effect on the site weight. For the quality of the chain issues, I will be in the blog after the share.

Link Farms

Exchange links

Exchange links is not very normal SEO means, why still count as cheating way? Very simple, exchange links is indeed SEO optimization process common white hat means, but the link is not the more the better, the exchange of links or need to have a degree! Over this degree, Search engines may be judged to be a certain degree of cheating. Therefore, we generally best to control the number of links within 30, of course, if someone else's friend chain over this amount, we also had better not to do friends chain, on the one hand, the effect has not been very good, on the other hand if the other station received punishment you will be implicated.

Purchase links

At this point, seoer who have not bought links may not be sure why this is counted as cheating. Quite simply, search engines are now able to recognize the behavior of trading links because the Black hat is so common that Baidu has to devise an algorithm to curb trading links. So how did the search engine identify the links you bought? The personal summary has the following two aspects:

1, the general sellers will not only sell you a person link, will also sell to others, and these links include all walks of life links, cohabitation, and links are concentrated in this site, then the search engine can easily identify which site in the sale of links, which sites in the purchase of links, thereby punishing the site.

2, buy links generally buy a lot, not only buy one or two, so the effect is not obvious, so, search engine can detect your chain surges, and are the weight of a one-way link, nature can identify in the buy link.

Of course, the above, search engine is not an obvious basis for judgment, so, all things pay attention to a degree, Master Good will play a very good effect, do the past is difficult to escape punishment.

Use expired domain name

Some cheaters will buy the domain name just expired, because the domain name itself has a certain weight value, through the purchase of domain name can directly obtain high weight.

Page redirection

This does not refer to 301 redirects, but the Web site program itself to achieve a function: To identify visitors are tourists or search engine crawler, if it is a tourist page to display the user needs of the content, if the search engine crawler, the search engine to provide stacked keywords, links and other cheating, not conducive to user experience pages.
