In fact, many of the links to buy black links are obtained by Trojans on major websites with a wide range. If you buy these links, these pr are usually relatively high, however, the relevance with your website seems to be poor. For example, if you are using a car-type website and the purchased links are all government-type websites, there is no relevance link, search engines are generally processed as black chains!
2. Unstable links
After purchasing external links, many websites find that links do not have any benefits for their websites. What should I do? I have to remove these links and then purchase new ones, in this way, the external chain will naturally become unstable, and the instability of the external chain is one of the basis for the search engine to judge!
3. Location of external links
Generally, the location of a black chain is hidden in the footer or navigation bar of a website, or in the navigation bar of some advertisers. For these fixed locations, the search engine can easily determine the location, this reduces the weight of these external links, and even lowers your website privilege!
4. Analyze the black chain transactions of other websites
In fact, many black links are sold through some fixed sites, and the search engine can determine on these sites that the websites are infected with Trojans, those websites have the behavior of buying and selling black links, so as to carry out certain tracking and investigation. During this time, some websites will be associated and their weight will be reduced!
Since the search engine can determine that we have purchased a black chain, what should we do? Is there no market for a black chain or a sales link? Black chain should be avoided as much as possible, and sales links can be improved by the following methods, so as not to be killed by search engines!
I. Sources of links should be diversified
When purchasing a normal external link, pay attention to the diversity of keywords and anchor texts. Pay attention to the diversity of websites at ordinary times. Do not always buy on the same website. Of course, the exception of sending a soft link is, keywords should be analyzed based on their own situation, and cannot be replaced by any spam keyword!
2. Regular increase of external links
The construction of external chains is also a long-term process. It is impossible to see a large number of external chains within one day, nor to disappear a large number of external chains within one day, in addition, regular increase is required. This is the road to normal expansion of external chains!
3. Do not find websites that sell advertisements.

IV. Forms of external links
External links cannot always appear at the bottom or on navigation pages. External links can be text links or image links, it can also be a link on the home page or on the internal page. In short, it is more beneficial!
