Research Profitable domain name for your business/blog

It is better to buy a new domain and create a big brand with authority. High authority expired domain may have a negative history and lots of broken links that impact SEO negatively. I suggest you buy a new one.

$500 domain name= It will be the price on Godaddy Domain Appraisal Tool. You can buy it at regular price from anyone. But the domain can have a price of $500+ in the future according to Godaddy
You have to consider several things as a part of domain research before buying a domain name-

1. Easy to Type
2. Easy to Remember
3. Reflect brand, vision, and Niche
4. You have to choose a shorter name
5. Should have keyphrase(or, part of it) in the domain name
6. Avoid slangs
7. .com is the best. Less popular TLD can be used if it can meet other criteria
8. Don't buy the trademark domain even if it meets everything
9. Buy Unique domain
10. Try to avoid numbers
