How to judge the quality and value of a second-hand domain name?

Older domain names tend to have more advantages because search engines may have accumulated a certain degree of trust and weight for them, and their inclusion and ranking performance may be relatively better. For example, a domain name that has existed for more than 5 years and has a record of legal and compliant use may have a higher starting point in terms of search engine optimization (SEO) than a newly registered domain name.

The quality and value of a second-hand domain name can be judged from the following aspects:

Age and history of the domain name

Age: Older domain names tend to have more advantages because search engines may have accumulated a certain degree of trust and weight for them, and their inclusion and ranking performance may be relatively better. For example, a domain name that has existed for more than 5 years and has a record of legal and compliant use may have a higher starting point in terms of search engine optimization (SEO) than a newly registered domain name.

Historical use: It is crucial to carefully understand the previous use of the domain name. If it has been used for a formal, high-quality website in the field related to your desired business, it may retain a certain amount of high-quality external links, user traffic, and brand influence. On the contrary, if it was previously used for a website that violates regulations, is vulgar, or has copyright disputes, such as a site that once spread pirated film and television resources, then such a domain name is likely to have search engine penalty records, negative user impressions, and other problems, and its quality and value will be greatly reduced. You can use Internet archiving tools (such as Wayback Machine) to view past web page snapshots of the domain name to understand its historical content, or you can ask the original domain name owner to provide detailed usage history and other information.

Search engine related indicators

Domain Authority (DA): This is an indicator to measure the overall influence of a domain name in a search engine. The higher the value (usually the full score is 100 points), the higher the quality of the domain name and the greater the potential for a better ranking in search results. For example, the domain names of some well-known authoritative websites may have a DA value of more than 70 points, while the initial DA value of new domain names is often lower. You can use some SEO tools (such as Moz, Ahrefs, etc.) to query the DA value of second-hand domain names.

Page Authority (PA): It mainly reflects the weight of specific pages under the domain name in the search engine. Although it focuses on the page level, it can also reflect the overall quality of the domain name. For domain names with more high-quality content pages and higher PA values, it is more worth considering. You can also use professional SEO tools for query analysis.

Inclusion and ranking performance: Check the number of domain names that have been included in search engines in the past, and whether some keywords can get good natural rankings. For example, if a second-hand domain name previously operated a website with a large number of pages included by search engines, and some core keywords can be ranked in the first few pages of search results, it means that it has good search engine affinity, and it is easier to attract traffic when used to build a website in the future, and its quality and value are relatively high.

Domain name external link situation

Number of external links: High-quality external links are equivalent to other websites' "votes" for the domain name. The more the number and the more extensive and authoritative the source, the greater the value of the domain name. For example, if a second-hand e-commerce domain name has many links from well-known industry media websites, relevant authoritative forums, etc., then its credibility in the eyes of search engines and users will be improved, which will be of great help for the subsequent development of e-commerce business and the improvement of website weight.

External link quality: Not only the number of external links should be considered, but also the quality of external links should be examined. High-quality external links usually come from websites with high weight, large traffic, and strong industry relevance. If most of the external links of a domain name are from some low-quality, spam websites, it may have a negative impact on it, and may even be regarded as cheating by search engines and punished, so it is necessary to carefully identify it. You can also use SEO tools to analyze the relevant situation of external links.

Domain name keyword value

Whether it contains popular keywords: If the domain name directly contains popular keywords of the target industry, it is very beneficial for search engine optimization and user memory. For example, if you want to make a fitness equipment sales website, if the second-hand domain name contains relevant popular English keywords such as "fitness" and "equipment", or the corresponding Chinese keyword pinyin, then when users search for related content, the domain name has a higher probability of matching the search keywords, and it is easier to be displayed, and its value is higher.

Keyword commercial value: Consider the commercial value of keywords in the domain name, that is, whether these keywords can bring actual commercial conversion to subsequent business. For example, in the field of financial investment, keywords such as "investment" and "wealth" have higher commercial value because they are closely related to potential customer needs and profit models. Second-hand domain names containing such keywords are often more popular.

Length and memorability of domain names

Length: Generally speaking, the shorter the domain name, the easier it is for users to remember and input, and its value is relatively higher. Short domain names are easy to spread, and can be more efficiently recognized and accessed by users in scenarios such as advertising and word-of-mouth communication. Short domain names such as "jd.com" and "taobao.com" are concise and unforgettable. Of course, some meaningful and slightly longer domain names are also valuable if they are easy to remember and catchy. For example, "ele.me" has a few characters, but it is catchy and easy to remember.

Memorability: In addition to the length factor, the memorability of a domain name is also reflected in whether its composition conforms to people's language habits and logical thinking. For example, domain names composed of some common word combinations, homophones, and figurative expressions will be easier to remember. For example, "51job.com" (homonymous with "I want to work") is very memorable and can quickly leave an impression in the minds of users, increasing the overall value of the domain name.

Domain name suffix selection

The influence of common suffixes: Different domain name suffixes differ in terms of public cognition and search engine recognition. For example, .com domain names are generally considered to be one of the most valuable domain name suffixes due to their strong global universality and high recognition. They are suitable for various commercial and industry websites, etc.; .net domain names are mostly used in network service-related fields; .org is often associated with non-profit organizations. Under similar conditions, second-hand domain names with the .com suffix are often more popular and have relatively higher value.

Targetedness of specific industry suffixes: Nowadays, there are also many domain name suffixes for specific industries, such as .travel (tourism industry), .edu (educational institutions), .tech (technology field), etc. If the suffix of the second-hand domain name is highly consistent with the industry to which the business you plan to develop belongs, then it has advantages in attracting target users and reflecting industry professionalism, and can also increase its quality and value. For example, a travel company uses a second-hand domain name with a .travel suffix, which can more intuitively identify its industry attributes for tourists, helping to enhance its brand image and business expansion.

Market price and supply-demand relationship of domain names

Reference to past transaction prices: You can check the historical transaction prices of similar domain names on domain name trading platforms (such as Sedo, NameJet, etc.) to understand the approximate market price range of the domain name under its type and characteristics, so as to judge whether the price of the second-hand domain name you are currently concerned about is reasonable, and then evaluate its value from the side. Different types of domain names, such as single-spelling domain names, double-spelling domain names, English word domain names, etc., have very different price ranges, which require comprehensive comparative analysis.

Influence of supply and demand relationship: If a particular type of second-hand domain name has a large demand in the market and a small supply, its price will often rise, and its value will also increase accordingly. For example, with the rise of the short video industry, the demand for domain names containing popular keywords related to short videos has increased. If such second-hand domain names appear at this time, they will be more popular in the market and their value will be higher than before.

Taking all the above factors into consideration, you can more comprehensively and accurately judge the quality and value of a second-hand domain name, and then decide whether it is worth buying and using for your own website construction or other related business purposes.
