The main options
A .com is the most familiar extension worldwide and is the natural choice if you want an international audience. A .ng or .com.ng is a Nigerian country-level domain that signals a Nigerian business to customers and to search engines. Each is a legitimate choice; the right one depends on who you serve.
How the extension affects SEO
Country-level domains give search engines a clear signal about which country a site is intended for, which can help when your customers are mainly in Nigeria. A .com has no built-in country signal, so it relies on other signals such as content, addresses and links. Neither extension is a magic ranking factor - content quality and trust matter far more.
Choosing the name itself
Prefer a name that is short, easy to spell aloud and matches your business name. Avoid hyphens, numbers and unusual spellings that customers will get wrong. Check that the name is not confusingly close to another brand, and consider securing the obvious variants if your budget allows.
Protect your ownership
Register the domain in your own or your company's name, with an email address you control, and keep the login details safe. Do not let a developer or agency register it in their name. Enable auto-renewal and note the expiry date, because an expired domain can take your website and email down with it.
Set it up correctly for search
Serve the site over HTTPS and choose one preferred version - with or without www - and permanently redirect the other to it. Make sure the canonical URLs and sitemap use that version. Duplicate versions of the same site split signals and confuse crawlers.
Frequently asked questions
Is .com.ng or .ng better for a Nigerian business?
Both signal a Nigerian focus. Choose whichever is available, easy to remember and consistent with your branding, and then use it consistently everywhere.
Should I buy both a .com and a .ng?
If you can afford it, registering both protects your brand. Pick one as the main site and redirect the other to it so search engines see a single version.
