The .com Domain Checklist: 12 Checks Before You Register
You found a .com you love. Before you click register, run it through this checklist. Each item takes under two minutes and catches a specific mistake that has forced someone, somewhere, to rebrand a year in. The order matters: the cheap checks come first so you can rule out bad names fast and only spend trademark-search time on real finalists.
Why a checklist beats intuition
A great-sounding name can still fail one quiet test that costs you the brand. A taken Instagram handle fractures your identity. A trademark conflict in your category gets you a cease-and-desist on month thirteen. A premium-priced aftermarket .com you discover only at checkout drains the budget you needed for ads. Intuition catches the obvious failures; a checklist catches the boring ones that actually kill brands. Run all twelve before you register, every time.
Check 1: The .com is actually available, verified against the live registry
Roughly nine out of ten brandable .coms are already taken. From our own dataset of brandable name ideas checked against the live .com registry, only about 7.4 percent come back available, the rest are squatted, parked, or owned. Verify against the authoritative .com registry, not a registrar autocomplete that can lag by hours, before you do anything else.
Check 2: Confirm the registrar price, not the aftermarket price
A standard new .com registration costs ten to fifteen dollars per year at any major registrar. If your finalist shows up at two hundred, two thousand, or twenty thousand dollars, it is an aftermarket domain that someone else already owns and is reselling. That is a sunk cost before you earn a dollar. Decide explicitly whether the name is worth premium spend, or move on to a free-registration alternative.
Check 3: Length is under 15 characters
You will type your domain hundreds of times per year and your audience will share it verbally. Every extra character is friction in word of mouth, business cards, and verbal recall. Under twelve is ideal, under fifteen is the working ceiling. If you are over fifteen, try cutting a connector word or coining a near-word version (Spotify, Olipop, Flickr, Tumblr) before you commit.
Check 4: Passes the verbal-spell test on the first try
Say the name aloud to someone who has never heard it. If they spell it back correctly on the first attempt, keep it. If they hesitate, ask you to repeat it, or spell it phonetically wrong, the name will leak traffic every time it is recommended verbally. Hard-to-spell names cost you the friend-recommends-you channel, which is the cheapest and highest-converting channel you have.
Check 5: No hyphens, no numbers, no creative spelling traps
A hyphen in a domain (my-brand.com) signals second choice to anyone who knows the .com landscape and competes directly with the un-hyphenated version, which someone else already owns. Numbers (4-, -7, etc.) introduce the same verbal-sharing ambiguity as homophones. Replacing letters with numbers (Kr8tive, Fly2) reads as dated. If you find yourself reaching for these, your name is fighting the .com availability ceiling, not winning at branding.
Check 6: The Instagram handle is available
A brand with a free .com but a taken Instagram handle is already fractured. Your audience searches for you across platforms; mismatched handles erode trust and conversion. Check the exact handle and the closest acceptable variation (no underscores, no the- prefix) before you commit. If Instagram is gone to an active account, the name is gone.
Check 7: The Pinterest handle is available (for content brands)
For mom, food, fashion, lifestyle, fitness, finance, beauty, wellness, gardening, home, DIY, and travel brands, Pinterest is a top traffic source. Check the Pinterest handle alongside Instagram. A taken Pinterest handle in your niche category is a worse problem than a taken Twitter handle outside it.
Check 8: No active trademark in your category
A free .com does not mean the name is yours to use. Run a free search at uspto.gov (USPTO TESS) for any registered or pending trademark in your product category. A registered mark in your category will force you to rebrand later, often after you have built real equity. This check takes five minutes and is the single most expensive one to skip.
Check 9: A Google search shows no major existing brand using the same name
Even without a trademark, an established business using your name as their brand will out-rank you on your own brand searches forever. Google the exact name in quotes. If the first page is dominated by an existing company, especially in an adjacent or related space, expect years of brand-search confusion and skip it.
Check 10: The name still fits if your scope grows
SourdoughSarah.com is a trap if you ever want to write about bread, then baking, then cookbooks, then a paid newsletter on creative work in general. A name tied to today's niche becomes a cage in eighteen months. Pick a name with conceptual range: an evocative word, a craft or nature noun, a coined brand, not a literal description of this quarter's content focus.
Check 11: Auto-renew is on and the contact email is one you will keep
Lapsed .com renewals are how brands lose their domain to a drop-catcher and end up paying ten thousand dollars to a reseller two weeks later. Set auto-renew at registration. Use a contact email tied to a permanent account, not a work email you might lose access to in a job change.
Check 12: WHOIS privacy is enabled
Without WHOIS privacy, your home address and phone number become public on every domain-lookup site. Every major registrar offers free WHOIS privacy now. Confirm it is enabled before, not after, you point the domain at a live site.

How long does each check take?
The full twelve-point checklist takes about fifteen to twenty minutes per finalist name. Availability, length, spell test, and the social handles run under a minute each; the trademark search and Google scan take three to five minutes; auto-renew and WHOIS privacy are one-click registrar settings.
What if my finalist fails one check?
It depends which one. Length, spelling, or scope failures (checks 3, 4, 10) are usually fatal because they affect every future share. Social-handle failures (6, 7) are fixable by picking a close variation if the account is dormant, but a fractured handle with an active competing account is a hard no. Trademark or Google-collision failures (8, 9) are always fatal.
Do I really need WHOIS privacy if I am only running a blog?
Yes. Without privacy, your name, home address, and phone become public on every WHOIS lookup tool and are scraped into spam, robocall, and SEO-pitch databases within days. WHOIS privacy is free at every major registrar and there is no reason to leave it off.
Is .co or .io a fine fallback if the .com fails check 1?
For most consumer-facing brands, no. The default assumption from non-technical readers is still .com, and traffic that bounces from yourbrand.co to yourbrand.com (owned by someone else) is lost forever. Use the freed-up creative budget to pick a different .com you can actually own, not a downgrade on a taken name.
How do I run check 8 (trademark) without a lawyer?
For a first-pass clearance, search uspto.gov's TESS database (free) for your exact name and close variations in your product category. A clean TESS search is not legal advice, but it rules out the obvious conflicts. Once the name has revenue worth protecting, a paid trademark search and filing become worth the spend.
What is the single most-skipped check in this list?
The trademark search (check 8). It feels like overkill at the naming stage, but it is the cheapest check by far relative to the cost of rebranding after a cease-and-desist a year in. Five minutes on TESS has saved more brands than every other check on this list combined.
Can DomainGenius run any of these checks for me automatically?
The generator handles checks 1, 3, 4, and 5 in real time: it generates names verified available against the live .com registry, filtered for length and pronounceability. Checks 6 through 12 (social handles, trademark, Google collision, registrar settings) are manual but each take under five minutes per finalist.
Written by the DomainGenius team. We generate brandable names and verify each one against the live .com registry, so this guidance comes from checking thousands of real name ideas, not theory.
