The hyperlink cheating algorithm upgrade launched by Baidu this time has caused a large number of websites to be demoted. A few days ago, I also published my personal opinion on SEO, "Baidu algorithm updates should focus on content and user experience details." Today we continue to analyze the topic of links. Nowadays, links are the key target of search engines. Are you afraid of external links? In fact, the most dangerous time is the most effective time. In the stage of severe punishment for external links, you only need to publish external links in the way specified by the search engine, and the effect is unnecessary. doubt.
Buying links is one of the key targets of this algorithm upgrade. In fact, in November 2011, I published an article about buying links: "Link Health Analysis: Buying Links Will Die" Now Baidu is indeed " "Cash out", let's analyze how Baidu hyperlink cheating algorithm identifies website purchase links from three aspects:
1. Ratio of import and export links
Links are passed between websites. Generally, a website has both incoming links and outgoing links. Of course, this depends on the website industry, and the proportion of the number of links is also different, similar to some government, official and For authoritative websites, incoming links are generally much larger than outgoing links. For general types of websites, if the ratio of import and export links is too outrageous, then Baidu can judge that this website must have purchase links, as shown in the picture of the site:
The number of external links reaches 187, but there is only one export link. This ratio is too disparate and only some government-type websites can achieve it.
In fact, a moderate amount of friendly links can reduce the risk of website penalties because it can reduce the ratio between incoming and outgoing links. (The link here actually has nothing to do with Baidu’s related domains.)
2. Source of the link
The link sources of general websites are very common, and they are obtained through friendly links, forums, blogs, etc. However, some news sites, educational industry, government-type edu, gov-type websites are rare but not available. Generally, It can only be obtained through unconventional means, one of which is purchasing. Baidu can detect whether your link was obtained through purchase.
In addition, Baidu’s requirement for a link is whether it has a recommendation function. Many of the links purchased are links to websites in unrelated industries. Although judging whether a link has a recommendation function is only relative, if the industry is too different, the probability of recommendation function will become apparent. It's ethereal. If Baidu penalizes your website, it may not be because it determines that you purchased the link, but because the link is of little significance and it will be demoted.
3. The brand value of the website
The length of the domain name cannot determine the brand value of the website. Many websites can be built in a short time with funds. Brand value is a reference indicator for judging whether a website can obtain links. If no one even searches for the name of a website, why would others make individual links for you?
Therefore, when Baidu analyzes the source of links, it may first determine whether your website has a certain brand value, including media exposure, user search volume, etc. User search volume can be directly reflected from the Baidu Index tool.
Finally, let me talk about a question that many webmasters have: Why are some websites not punished for purchasing links? First of all, it can be said clearly that any optimization that does not comply with Baidu regulations will be punished, but some punishments cannot be reflected directly through data. , for example, the score of a high-weighted website is 90 points, and 5 points may be deducted because of purchasing a link, and the ranking may still be very strong. However, if your website only has 5 points, and 5 points are deducted for purchasing links, then your website will be directly ranked. Entering the eighteenth level of hell, this is just a simple idea.
Of course, some websites may not have their purchase links identified within a short period of time, and it is only a matter of time before their rights are reduced.
In fact, optimization methods that rely on links to rank have great risks, and they are also the focus of Baidu's "care". Many SEO training sites rely on students' resources to make individual links. Although it is voluntary and many are related sites, it will also affect the principle of fair competition. External links may be very strong, but what about the user experience on the site? In fact, the current optimization is : The more links, the greater the risk (under the same conditions). Again: Baidu algorithm updates should focus on content and user experience details.
