When .agency is the strongest choice
Choose .agency when the word agency is part of your positioning. It works well for marketing firms, creative studios, recruitment agencies, PR consultancies, property agencies and specialist service teams.
The advantage is clarity. A name like northstar.agency tells people what kind of business they are dealing with before they read the website copy. It can also save you from awkward .com compromises such as long names, hyphens or extra words.
When .co.za is the stronger choice
Choose .co.za when most of your clients are in South Africa and local familiarity matters. It is inexpensive, widely trusted and expected by many local buyers.
The limitation is that .co.za does not describe the business type. A visitor may trust that you are local, but the domain itself does not say whether you are a marketing agency, recruitment agency or consulting firm.
When .com is the stronger choice
Choose .com when you want the most familiar global extension or plan to sell beyond South Africa. It is still the default for many commercial brands.
The challenge is availability. Short, clean .com names are often taken, expensive or only available with compromises. If the .com makes your brand worse, .agency may be the cleaner public-facing choice.
