Gu Mu's resume: The difference between black hat and white hat techniques in SEO optimization

As the name suggests, white hat SEO optimization means using the correct method to make SEO operations proceed step by step. White hat is worth recommending in the implementation of SEO operators, because it is carried out step by step in a healthy manner according to the rules of search engines. The only effect is that it requires long-term accumulation and gradually improves. This is one of the reasons why SEO operators may be scolded by some impatient bosses. SEO optimization training plan: Chinese talents will now explain to us that white hat is the industry's search engine optimization path. Although the effect is not obvious in the early stage and the investment will be time-consuming and laborious, when it accumulates to a certain level, companies often do not need to spend much effort to make the effects and traffic appear continuously and relatively stably. Black hat SEO optimization, and black hat is the so-called cheating method, that is, the operator uses cheating methods to let the search engine crawl and get relevant results. Of course, its advantage is that it is fast and more conducive to short-term profits. Some black hat methods usually have a lot of spam links, hidden bridge pages, keyword stacking and other technical and non-technical methods, but the disadvantage is fatal. Once discovered, they will be severely punished by search engines, and it will be difficult to have a good ranking in the future. If black hats are used repeatedly, they may be on the blacklist and never see the light of day. The gray hat SEO optimization is to use some small skills, but it will not be blacklisted by the search engine. It is in between the two. It mainly finds some loopholes in the search engine and then accelerates the ranking. However, it is difficult for general SEO operators to grasp it, because it is not a single technical problem, but it may accidentally step into the black hat category.

“There are three types of people in the world: those who have been hacked, those who don’t know they have been hacked, and those who don’t admit they have been hacked.”

A young man in a gray shirt and black trousers was giving a speech. He was of medium height and thin, with one hand in his pocket, looking a little serious. There were more than 300 people sitting in the dark below the stage, most of them were hackers from all over the place. The audience only knew that the young man's online name was "Pig Man" and that he was the number one white hat hacker in the Wuyun community.

In the world of hackers, the titles of black hat and white hat represent two opposing roles - villains who profit from network information and heroes who protect network security. This saying comes from early American westerns that used white hats and black hats to distinguish between good and evil.

This was at the first Wuyun Security Summit on September 12, 2014. The organizer of the summit is Wuyun.com, a well-known third-party security vulnerability platform in China. Wuyun.com was founded by Fang Xiaodun, a former Baidu security expert, in 2010 and has gradually become a gathering place for white hat hackers. They are equivalent to the "woodpeckers" of the Internet, monitoring the vulnerabilities of various websites at any time and issuing warnings.

"Then I thought of the fourth possibility, which is being hacked." "Pig Man" continued in his southern accent. He was not exaggerating. On the other side of the podium, an attack on the mobile phones of the audience was underway - the private information of at least three people's bank card balances and one person's stock transactions were displayed on the conference projection screen.

In the network world composed of information flows, such attacks occur almost every moment. The more people rely on the Internet, the more dangerous they are.

When hackers were born, the international situation was actually not like this. The word "hacker" originally referred to a worker who chopped wood with an axe. The word was not introduced into the computer circle until the 1960s. According to the book "Hackers: Heroes of the Computer Age", the group originated at the Massachusetts Institute of Technology in the 1950s. A group of students believed that information should be public and accessible to everyone. They then broke into a computer system restricted to government use.

my country's hackers did not appear until the 1990s. They started by cracking software and copying small software using floppy disks. Their first collective action was quite characteristic of the times: after the anti-Chinese movement in Indonesia, they sent spam to the mailboxes of Indonesian government websites.

The initial idealism was gradually replaced by the temptation of money. In the underground world where black hats are hidden, an industrial chain of trading information has been formed, which has brought huge benefits to black hats. Fang Xiaodun, the founder of Wuyun, once said in an interview that perhaps an inconspicuous hacker may live in a good house and drive a good car one day. "The income gap between the strongest black hat and white hat professionals is roughly the difference between a daily salary of 10,000 yuan and a monthly salary of 10,000 yuan."

The threat posed by black hats has led to a surge in market demand for network security. According to a report in the professional magazine "Information Security and Communication Confidentiality", in 2012, the scale of my country's network security industry reached 21.64 billion yuan, a year-on-year increase of 20.9%. Among A-share listed companies, there are at least 12 companies that touch upon the concept of cybersecurity, not including Qihoo 360 (NYSE: QIHU), which is listed in the United States and has a market value of US$10 billion. The company claims to have "the strongest white hat army in the Eastern Hemisphere."

On the secret battlefield, the competition between white hats and black hats has already begun. They cannot see each other and can only feel each other's presence when they fight each other again and again.

In the battle of right and wrong, every letter is like a cow. After skinning, bones and meat are removed, at 7 o'clock in the morning, only a pool of blood remains.

Meng Zhuo, co-founder of Wuyun, his ID on Wuyun is "Mad Dog".
