Today, I suddenly thought of a topic: an extensive domain analysis. This is a topic that is rarely mentioned in recent years. But in the early stage of SEO, many SEO optimization personnel used to “cheat”, fabricate N plurality of secondary domain names to enable Baidu to include and improve rankings. But in today, if the domain name encounters malicious pan-analyzing, others are unlikely, once negligence, often do not pay, the pan-domain name analysis is still worthy of our concern and understand.

1. What is the general domain name resolution?

Pan domain name resolution refers to the use of wildcard * to do a secondary domain name to implement all secondary domain names to point the same top domain name. Add any subdomains to the top-level domain name, you can access the intended top-level domain name address. For example, you can visit the website if you enter any character before the May90.com domain name, you can access any character before the May90.com domain name.

2. How is the general domain name resolution?

Many small partners will be very curious after understanding the concept: how the general domain name resolution is set. Below we are analyzed by Alibaba Cloud domain name.

Step 1. Log in to Alibaba Cloud Console

Step 2. Domain – Analysis

Step 3. Host Record Add “*”

STEP 4. Wait for extension, it takes effect in 0.5 to 1 hour.

3. What is the impact of the general domain name to SEO optimization?

1. Increased inclusion

After the domain name is broadly analyzed, there will be a large number of secondary domain names, and these secondary domain names are also captured by search engine spiders, and they will be included, because it is the same content, this collection is not very good.

2. Repeat

After the domain name is defined, you can resolve countless domain names, which will result in a large number of repetitions, which will also cause internal competition between the primary domain and secondary domain names. Duplicate content excessively affect the user search experience, search engine spider It is also very unfriend.

For our personal SEO blog, the general domain name resolution is not very friendly, and it is not recommended.

Four. Prevent domain names

In SEO optimization, website security is very important, and the same domain security is also important. Once a domain name is issued, the general manifestation is generally degraded in the domain name, and there is a large number of secondary domain names, if these secondary domains are taken to do illegal sites, the primary domain name will be implicated.

1. Select a domain name service provider with a certain visibility

Not all domain name service providers have strength, technology. Many domain name service providers have security vulnerabilities, which cannot be solved, causing hackers to easily analyze domain names. There are even some domain name service providers to perform domain name locks for the domain name, and the holders cannot modify, but hackers can be easily modified. So when we choose a domain name service provider, we must choose a domain name service provider with strength, high security, and avoid problems in the future.

2. Domain holders set complex passwords

When purchasing the domain name, the registered account and the password are too simple, and even a series of servers and buildings, etc., the hacker can be simply acquired through the weak mouth. So I suggest that when you purchase a domain name, the registered account is as complicated, password usage combinations using letters, numbers, uppercases, compliance.

3. Set domain name privacy protection

When you register in a domain name, it is best to choose the WHOIS information that hides the relevant domain name, avoid your own privacy by others maliciously, break the domain account.

4. Set the domain name resolution security lock

In order to avoid domain names that are maliciously analyzed by others, many well-known domain name service providers have launched a domain name security lock. When others try to parse domain names, they need to provide the corresponding dynamic password.

More, I believe that everyone has a certain understanding of the preference analysis, and our personal blogs avoid extension-domain analysis as much as possible in SEO optimization, but also pays attention to the security of domain names.
