1. Make it easy to say
If you have to explain the spelling every time you say the name, it creates friction. Prefer names that can be understood after hearing them once.
2. Keep it reasonably short
Shorter names are generally easier to type and share, but clarity matters more than chasing an extremely short name. A clear two-word domain can be better than a confusing five-letter abbreviation.
3. Avoid unnecessary punctuation
Hyphens and unusual spellings can make a domain harder to communicate. They are not automatically bad, but use them only when they genuinely improve clarity.
4. Think about the project, not the current page
If you expect the project to expand, choose a name that does not trap you inside one tiny feature. A domain chosen for a single calculator may become awkward if the site later becomes a broader collection of tools.
5. Check the extension and renewal price
The first-year price is not the whole cost. Check the renewal price, transfer rules and any additional charges before registering. Also make sure the registrar provides the DNS controls you will need.
6. Check for obvious conflicts
Search the name before registering it. Look for existing businesses, products and established brands with the same or confusingly similar name. A technically available domain is not automatically a good choice.
A quick decision test
- Can someone spell it after hearing it?
- Can you type it without checking?
- Does it still make sense if the project grows?
- Have you checked obvious existing uses?
- Are the renewal costs acceptable?
If the answer is yes to all five, stop searching. Spending another hour looking for a theoretically perfect domain is often less valuable than actually building the project.
