Impact of domain names and hosts on Seo
Domain names and hosts are the foundation of websites. commercial websites should pay special attention to the image and quality when selecting domain names and hosts, laying a solid foundation for network marketing. At the same time, selecting a domain name and a host is also the first step in search engine optimization.

Domain name selection and Seo
Domain Name and IP Address: each website domain name corresponds to an IP address, which is a digital identifier assigned to each computer or network device on the network. The domain name must be resolved by the Domain Name Server (DNS) and converted to a digital IP address, so that the computer can understand and recognize the domain name, such: 219.136.248.149 most SME websites are stored on several virtual hosts divided by one server. Multiple websites share one server and IP address, in some Web servers, hundreds of domain names share an IP address. This is a low cost for webmasters, but it brings the following potential risks to the search engine ranking of websites:

1. If other websites on the shared host are punished by the search engine, they will more or less affect your website. If a website under the same IP address is cheated, our search engine will punish all websites under the same IP address. Fortunately, most search engines are not so arbitrary, such as Google, and generally do not carry out such attach punishment.

2. If the search engine punishes some spammer servers and its IP address is regarded as spam, all the websites associated with this IP address will be implicated, drop the rankings of these websites or clear them in search engines.

Second-level domain name (second-level domain name ):
Second-level domain name form such as: yourname.netsing.cn, rather than http://www.netsing.cn/

Having your own independent domain name is the foundation for your website to be friendly to search engines. Currently, many websites provide free space, such as free blog space, free enterprise space, free self-help website construction, and e-commerce platforms. A second-level domain name is usually assigned to users, or the page is stored in a certain path of the website. This is not conducive to the search engine attaches great importance to your website. In addition to the inconvenience of user access, the second-level domain name also has the following drawbacks:

1. If the primary domain name of the second-level domain name you use is punished, your website will also be implicated;

2. Many search engines define the number of entries under each domain name (for example, http://www.netsing.cn/、english.netsing.cnand bbs.netsing.cn;

3. When the domain name supplier stops business, the website you work hard on will be lost with the loss of your domain name;

4. When ranking website traffic, all your traffic will be attributed to your top-level domain name.

It is best to register an independent domain name for your second-level domain name website and then perform domain name Forwarding (free of charge). Currently, many auction shops are suitable for this method, which is useful for customer access and website management.

Characters in a domain name: In addition to convenient access to the domain name, the search engine involves the question of whether the domain name contains keywords. If a website with English web content contains keywords in the domain name or uses compound keywords as domain names, they should be separated by a hyphen. For example: http://www.made-in-china.com/instead of http://www.madeinchina.com /. This is because search engines generally treat the separator "-" as a space, so they can identify your keywords and add points to the website rankings (although the impact is not great ). Keyword groups separated by hyphens can also obtain more phrase search results, such as http://www.madeinchina.com/recognized as only one word madeinchina, while made-in-China is regarded as a normal Made in China phrase.

In some search engine directories, the ranking order of the website's category directories is based on the numerical sequence of the domain name or website title name, or even the Chinese strokes. In general, the numbers are higher than the letters. Yahoo! According to China, "in the same category, websites are listed in pinyin order ". Google uses its original "webpage-level" technology to identify important websites that are frequently used and release them before directories to improve the efficiency of Web search ". In addition, you must pay attention to the selection of domain name suffixes. One idea is that, under the same circumstances, it represents the suffix of a non-commercial website. org and. net. COM has a higher ranking advantage. For Chinese websites, it represents the Chinese domain. CN and .com.cn are also less regional. COM has some advantages.

Host selection and Seo
Host Service Provider Selection:
The host has a great impact on the search engine ranking of the website. When looking for a host provider, do not just consider the price. If you submit a website to Google multiple times but Google has not indexed it, it may be that the server where the website is located has a problem. Therefore, pay special attention to the following points when selecting a server:

1. Avoid using free hosts
Because spammers, image websites, bridge pages, and other "Search Engine spam" often appear on free hosts, many search engines are reluctant to index websites on free hosts; at the same time, search engine directories such as Yahoo are difficult to include commercial sites from free hosts. In addition, it is difficult to guarantee the services of free hosts, such as server overload, slow speed, frequent downtime, and even service shutdown, which will directly affect website rankings.
2. Select a trusted host provider
Search engine indexProgramVisit included websites on a regular or irregular basis. For frequently-updated websites, Google's googlebot, commonly known as "Spider", performs a small "Crawl" every day and performs a large index once a month. If the web page cannot be opened or the download speed is slow when indexing occurs, the indexing will be abandoned. Therefore, your website must work normally at any time to win the joy of the spider. This requires the host system stored on the website to provide fast, stable, and secure services. It is best to have 24-hour customer service support and maintenance to ensure the fast, reliable, and stable operation of your website.

host transfer:
if you want to transfer the website's host service, you need to find a new supplier before canceling the original service provider. Create an account at the new service provider to ensure that all files are correctly uploaded to the new server. After the website is running on the new server, contact your original supplier to inform the other party that the cooperation will be terminated, but ensure that they will not close your website immediately. Contact your domain name registrar (maybe the original host provider) to change the Domain Name Server (DNS ). The domain name server function is to resolve your domain name to an IP address that can be recognized by the computer. Change the old Domain Name Server to a new one. This process takes about 24-48 hours to take effect. In rare cases, it may take 72 hours. During this period, if a search engine just captures your webpage, either the website on the old IP address or the website after the new domain name resolution takes effect, in short, there will be no blank files that cannot be opened by the website.
