Getting a perfect domain name can be challenging especially when you are looking to drive traffic. Some domains rank well with SEO than others and therefore one must make their choice well.
Here are some of the key factors one may consider next time before making the purchase;

1. Is it short and Memorable
2. Use broad keywords (does it include some of the keywords related to what you are doing)
3. Always go for the .com domain extension (if you want an alternative go for .net,.co, or .org)
4. Create subfolders rather than subdomains
5. Domain authority rating and backlinks (The higher the domain authority and the higher the number of backlinks the better your chances of growing your traffic)
