Setting Buy Criteria: The Filters Serious Domain Acquirers Use
Serious acquirers don't buy on instinct—they buy through filters. Here's how to build domain acquisition buy criteria that separate signal from noise and protect your capital.
Every domain acquirer eventually learns the same lesson: the market will show you thousands of names, and almost all of them are wrong for you. The difference between a portfolio that compounds and one that bleeds carrying costs isn't access to inventory—it's the discipline to say no quickly and yes rarely. That discipline lives in your domain acquisition buy criteria: the explicit filters that turn a vague sense of "this feels good" into a repeatable evaluation you can run in minutes and defend in years.
If a thesis tells you where to hunt, buy criteria tell you what qualifies once you're there. Below is the framework serious operators use to build filters that scale—and stay honest under pressure.
Why Buy Criteria Beat Instinct
Instinct is fast, but it's also expensive. It anchors on the first name you like, rewards the deals that make you feel clever, and quietly ignores the ones that don't fit a story you've already told yourself. Written criteria do the opposite: they force every candidate through the same gauntlet regardless of how it made you feel in the first ten seconds.
Buy criteria also make you faster, not slower. When you know your non-negotiables cold, you can clear ninety percent of what crosses your desk without a second thought—and reserve real analysis for the handful that survive the first cut. That's the paradox of good filters: they let you look at more deals precisely because they let you reject most of them instantly.
Criteria are the operational layer beneath your acquisition thesis. The thesis defines your worldview; the criteria enforce it deal by deal.
The Core Filters Every Acquirer Should Define
No two portfolios run identical filters, but strong criteria almost always address the same categories. Think of these as the columns you'd score every candidate against before money enters the conversation.
1. Name Quality and Brandability
This is where most evaluations start and where the most self-deception happens. Ask hard, specific questions rather than "do I like it?":
- Length and syllables: Can someone type it correctly after hearing it once over a phone call?
- Spelling risk: Are there homophones, dropped letters, or hyphen temptations that leak traffic to a competitor?
- Semantic weight: Does the name carry meaning a founder can build a story around, or is it just phonetically pleasant?
- Category fit: Would a serious operator in the target vertical be proud to put it on a pitch deck?
Brandability is the connective tissue between investment value and end-user demand. A name that survives this filter is a name a startup will actually pay to own—which is the entire point. For a deeper treatment of what separates investable names from disposable ones, see our breakdown of premium versus cheap domains.
2. Extension and Structure
The .com remains the default reserve currency of the domain world for a reason: it's the extension end users assume by muscle memory. That doesn't make every other extension worthless, but it does mean your criteria should be explicit about which extensions you'll hold, at what discount, and for which verticals. A .com that requires no explanation clears a bar that a newer extension has to earn its way over.
Structure matters too. Exact-match single words, tight two-word compounds, and clean brandables behave very differently on resale timelines. Your criteria should state which structures you'll pursue and which you'll pass on regardless of price.
3. Comparable Sales and Valuation Anchors
A name only qualifies if you can build a defensible value story around it. That means grounding your read in comparable sales—recent, relevant, and real, not aspirational one-offs someone screenshotted. Public sales data from established venues and industry reports gives you anchors; your job is to weight them honestly against the name in front of you.
A number you can't source from a comparable isn't a valuation—it's a wish. Buy criteria should require at least one credible anchor before a candidate advances.
Valuation discipline is inseparable from price discipline, which is why serious acquirers pair their quality filters with hard ceilings. Before you ever negotiate, decide what you won't pay—our guide to max bid discipline covers exactly how to set those ceilings and hold them.
4. Demand Signals and End-User Fit
The most durable domain value comes from names that a real business needs, not just names other investors admire. Look for evidence of live demand: is the keyword tied to a growing category, an active startup formation trend, or a vertical with well-capitalized buyers? A brandable in a hot sector clears a lower quality bar than a mediocre name in a saturated one.
This is where your criteria connect to your vertical and category thesis. If you've defined the sectors you believe in, demand-signal filters simply confirm a candidate sits inside that conviction rather than drifting outside it.
5. Legal and Trademark Clearance
No amount of brandability survives a trademark conflict. Every candidate should clear a basic legal filter before it advances: check for active marks, obvious brand collisions, and any registration history that suggests prior disputes. The registration record itself is worth understanding—ICANN's registrar documentation is a useful reference for how transfers and ownership work at the protocol level. A name that can't be cleanly owned isn't an asset; it's a liability wearing an asset's clothes.
Turning Filters Into a Scored Checklist
Written criteria only work when they're applied consistently, and consistency comes from structure. Convert your filters into a simple scoring pass:
- Hard gates first. Trademark conflict, unacceptable extension, unspellable name—any of these is an automatic no. Don't score what should be eliminated.
- Weighted scoring second. Rate the survivors across brandability, comparables, and demand fit. Weight the categories that matter most to your strategy.
- Threshold third. Set a minimum composite score a name must hit to advance to pricing. Below the line, it doesn't matter how much you like it.
A scored checklist does two things at once: it speeds your decisions and it creates a record. Over time, that record tells you which of your filters actually predicted outcomes and which just made you feel rigorous. Criteria should evolve—but only in response to evidence.
Keep Your Criteria Honest Over Time
The biggest risk with buy criteria isn't that you'll set them wrong at the start—it's that you'll quietly loosen them when you fall in love with a name that doesn't qualify. Every acquirer does this at least once. The fix is to pressure-test your filters against real deals on a schedule, not to abandon them in the moment. Our walkthrough on stress-testing your thesis against live deals shows how to keep that feedback loop tight.
It's also worth deciding, upfront, how much room you'll leave for exceptions. Purely rules-based buying can miss genuine outliers; purely opportunistic buying has no floor at all. The strongest operators land in between, and the tradeoffs are worth thinking through—we compare both approaches in thesis-driven versus opportunistic buying.
Criteria Are What Separate Collectors From Investors
Anyone can accumulate domains. Investors compound value because they buy through a filter that protects their capital and concentrates it in names the market will actually reward. Your buy criteria are that filter. Written down, scored, and defended, they turn the overwhelming noise of the domain market into a short, high-conviction shortlist—and they let you act decisively when the right name appears.
