Analysis of the impact of Baidu on the sale and sale of websites

First, let's take a look at how Baidu can determine whether a website is involved in buying and selling links.

There are two problems: Buy links and sell links. Baidu says that buying and selling links have the intention of super chain, that is to say, it is definitely not supported whether it is to buy or sell Baidu. But in fact, Baidu is not very good at screening, whether it is buying links or selling links, especially buying links. How can search engines determine this? Buying a link allows a website with higher weights to provide one-way links to its own website, but not all one-way links are bought. To be exact, the vast majority of such one-way links should not be bought. Obviously, this method cannot be determined. In fact, I personally think that it is basically impossible for Baidu to identify whether a website has purchased links by simply relying on machines, unless a website intentionally finds dead and adds many one-way links in batches in a short time, otherwise, whether a website has purchased a link or not, sometimes even if it is manually observed on the site, it cannot be clearly divided. After all, the machine is not human, and it is more difficult to distinguish it.

The other is selling links. In fact, Baidu has always been a hit, and the resolution method is relatively simple, that is, the number of exported links. However, how many links are exported? This Baidu has not given a definite number, and many SEO experts have stressed that they cannot export too many links. Even if they change friendship links, they should not change too many links. Because there are no exact numbers and different websites have different weights, the number of exported links is too large to trigger Baidu's punishment mechanism. That is to say, it is not very scientific to determine the number of exported links. I personally think that the more scientific way is to determine the ratio of the number of exported links to the total number of exported links to be obtained. For example, a website exports 300 links, however, only 50 of them have backlinks, that is to say, 250 of them are in the free export zone of this website. The search engine knows that there are too many export links in one way, and the webmaster also knows that the search engine knows this situation, so the search engine can doubt this time: Since your webmaster knows, if you still do this, will you ignore the interests of your website if there is no interest in buying and selling! Therefore, Baidu determines whether to sell links. It is more likely to be based on the ratio described above, rather than simply exporting the number of links.

Of course, there are two most direct but troublesome ways to judge. First, manually report and launch webmasters to report websites that sell links, find websites that sell links, and those websites that buy links will naturally go around. In addition, if you punish the websites that sell links, the links will have no value, and no one will buy them. Second, you can judge based on the actual market conditions. In fact, it should also be clear that the large users who sell links are basically the same, and the links on the websites that sell links usually contain related words, baidu can judge based on this point, but its name can be changed, and there are more than just those selling links, so this method is actually not scientific.

Next, let's think about how Baidu will deal with websites that sell and sell links.

I believe it is clear that Baidu sells links to its websites by directly downgrading permissions, stopping snapshot updates, and reducing indexing. So what will Baidu do with websites that buy links? I personally think that Baidu should have no way to determine whether a website has purchased a link. Of course, this is based on my poor IQ. Let's take a look at the problem, even if Baidu knows that a website has a link sales behavior, Baidu should not punish the website, at most, that is, it will not assign weight to these purchased links. Why? This is something that can be fake. For example, if Baidu punishes websites that buy links, I will buy links for competitor websites. How can Baidu tell the difference? People are far more complicated and flexible than machines, so Baidu will not punish websites that buy links, but will not give weight. Of course, this is enough, because it is useless to buy links.

Based on the above analysis, my personal opinion is: Baidu will determine whether a website has too many export links based on the ratio of the number of export links that a website gets back to the total number of export links, and then determine whether there is a text of the sales link. If the website exists, the website will be punished. After the punishment, the website will not be purchased by other websites for the value of the link, then its text will gradually disappear. In addition, Baidu has no way to determine whether a website has purchased a link. Even if it has a way to determine whether a website has purchased a link, Baidu will not punish the website that has been determined to have purchased the link, if Baidu does this, buying links to competitor websites becomes a new means of malicious competition. The above are my personal guesses about the strategy Baidu will adopt to buy and sell links to the website.
