What is a domain name and do I need my own?
A domain is your address on the web (yourname.com), rented yearly for around $10 to $20. For anything representing a business or a serious project: yes, unconditionally: it signals legitimacy, works in print and conversation, and moves with you between platforms. Register it where you control it, and consider it the one part of your website you truly own.
Technically, a domain is an entry in the global DNS that points a memorable name at your site’s actual location. Practically, it is identity: customers type it, search engines index reputation onto it, email lives at it, and every business card, invoice, and Instagram bio repeats it. Renting one costs $10 to $20 a year for a .com at honest registrars (watch first-year teasers that renew at premium rates, and never pay extra for "privacy protection" that good registrars include free).
The ownership point deserves emphasis because builders blur it. Platforms love to bundle a free first-year domain, registered through them, which quietly deepens lock-in: leaving the platform now involves a domain transfer too. Our standing advice: register the domain yourself at an independent registrar, point it at whatever platform you currently use, and the most valuable part of your web presence (the address and its accumulated SEO history) stays portable forever. Domain transfers between registrars are a regulated, standardized process (ICANN governs it), but avoiding the need beats exercising the right.
Who can skip a custom domain: hobby pages, experiments, link-in-bio pages where the platform address is conventional, and anything deliberately temporary. Everyone else, including the freelancer "not ready yet": the $15 a year buys the difference between yourname.wixsite.com/portfolio and yourname.com on the top of your resume. There is no cheaper credibility purchase on the internet.
