What are the precautions for using old domain names?

We've previously explained why old domain names are so popular and their three main advantages. So, how do we discover them? While using old domain names offers many benefits, what are some important things to keep in mind when using them?

Things to keep in mind when using old domain names:

① Determine the age of a domain name by its age, which is the website history, not the registration year.

② Check how many times the domain has been used since registration and how many websites it has hosted.

③ Try to choose domain names that have recently expired and still have web pages indexed. Because these domains are recently expired, search engine spiders frequently crawl them. Some good domains can even be indexed the day you create your website.

④ Set up a 404 page for new websites using old domain names. If your new website uses an old domain name, it's crucial to set up a 404 page. This is because some of the original web page URLs on the old domain name may no longer be available, making them inaccessible. This is unavoidable. Therefore, it's important to set up a 404 page. When users visit an error page, it redirects them to another page on your website. This reduces broken links caused by errors and helps with search engine indexing.

⑤ Check the history of old domain names. This focuses on two key factors: whether they've been severely penalized and the relevance of the content.

First, check to see if the domain has been blocked. If it has, be cautious and verify any past violations. If so, avoid choosing a domain name, as it's difficult for heavily penalized domains to regain search engine trust.
