Before Buying your Domain
Choose a relevant domain extension. While ".com" is the most popular, there are many other TLDs (Top-Level Domains) like ".net", ".org", ".biz", etc. You might also consider ccTLDs (Country Code Top-Level Domains) for region-specific businesses.
Choose a name that is brandable and resonates with the essence of your business.
Select a name that will stand the test of time and will remain relevant even as your business evolves.
Do a quick analysis of the domain names used by your competitors and try to differentiate yours.
Domain Name Generators
If you're stuck, use domain name generators like Domainir.com (https://domainir.com/domain-generator/), etc., to get suggestions based on your keywords.
Once you find a fine domain name that is available, purchase it immediately to prevent others from registering it.
