Question 1: what is black hat seo and what is black hat technology?
1. Stations
This is one of the most powerful black hats used today, because it is very simple, and a new player can do it with a little understanding of the principles, with low construction costs, with a server, with a domain name, with thousands of relevant stations, and then with a single station, with all the rest of the friendship linked to the main station, so that the key words of this home station will soon come up, which is the rationale for the group approach。
2. Hidden text
This is also a common technique for setting keywords in the same colour as the page's background and stacking them on this page so that the user does not see them, but the search engine is visible so that it does not affect the view of the user, and the search engine is able to see a significant increase in the density of the keyword, so that the ranking of the keyword is improved considerably, and some hidden text is difficult to find in the program, but manual is easy to discover, so it is severely punished once checked。
Hide links

This is a very numerous practice used by hackers, based on the principle of hacking some large websites that are linked to their websites and then posting hidden links to their websites, and we know that a large site that is relevant to us, if it has a link to us, is a huge increase in the ranking of our websites, the effect of which we have no idea is that it takes quite a lot of technology, so it is a very popular approach for hackers. Hiding links is not visible on the page, and to find them in the website's source file, regular hackers will hang them on the front page, without ruling out content, but in my experience, there are more pages on the front page, which is the principle of hiding links。
4. Pr hijacking
This is the most common way for some old birds to bully newcomers by using some technology to hijack some large station domain names for their domain names, thereby giving them a very high pr value at once, and then they sell them to a trading platform, deceiving some newcomers. We know that google pr values are updated only once in three months, and if they sell them in three months, that means that you've been deceived. I have a few friends who have been so deceived when i first got into the business, and i'm glad i asked the teacher, who told me that a way to check the site pr values was not deceived. The contents after the snapshot click are different from those directly entered on the web site。
5. Panorama
This is what has been seen in recent times as a very large number of websites that have been affected by this. The rationale for this approach is to hack into the domain name servers of large websites, and then decipher some secondary domain names from the main domain names of these large sites to serve them, and then to achieve their profit. We know that the second domain names from the main domain names of large sites have a considerable weight, so it has recently been found that there are a lot of such phenomena, which is also a black hat。
So that means that when we do a website, we don't add new sub-domain names or even web pages that are likely to be considered cheating by the search engine。
6. Link farms

It means that the website has been created as a farm dedicated to collecting site and exchange links to raise pr values, with little or no material content useful to users. Good rankings can be obtained quickly, but soon they will be k. Link farms have self-help or manual additions。
Negative seos
(b) producing a large number of garbage links to competitors, as the search engine penalizes a site with a heavy off-link; producing a large number of duplicates and even mirroring target sites with the target site, leaving the target site with a false image of its originality
8. Cloaking (invisible page or bridge page)
Two versions of a particular web page were produced, allowing search engines and viewers to see different web content (using the identification of visitors). The search engine captures this page with content organized solely to optimize certain keywords, while page viewers see another very different content. Cloaking is a typical seo cheat, and the search engine, once identified, severely punishes the website。
Question 2: reasons for and manner of punishment of websites and how to address them?
1. Security

The site security is divided into multiple types, such as gaps in website servers and too many black chains. In such cases, the search engine would naturally punish the site. This is mainly about another type of security: website information security. For example, when searching on the internet at 100 degrees, the website is hung, and there are some fishing sites or three information that is fraudulent, so that users can report them and natural sites are added to the new list. If there is a security risk alert to the website and if problems arise, site technicians can resolve them in a timely manner, the site will not be reported by the search engine and will naturally reduce the risk that the site will be penalized。
Content
The website does not optimize the publication of some articles on a daily basis, and some external links are ranked. This method did work in the past, and it is outdated. Many business stations do not have so many articles up-to-dates, and if they find hundreds or thousands of entries after the site sits, the site must have published a lot of articles every day, and how do they come from? Most of them are duplicated online. But there is no value in so many articles, because they are not viewed at all, and instead they increase the user-heat of the search engine。
3. Outlinks of garbage
The current outer chain cycle of 100 degrees is one week, so it would take about one week to add a general entry to the external chain of the website, and only after one week will this algorithm rank take effect. The first cycle is normally a spider's crawling cycle, which has to be crawling before it becomes effective. In order for spiders to climb our web site, high-quality external chains are required; the second cycle is the statistical cycle of your own outer chain, which is not always counted at all times, but is effective at all times, and it is impossible to rank the site now with the offline。
