NameBio is essential. I'm not going to bury that lead.
If you're buying or selling domains seriously and not checking comps, you're guessing. Sales history matters. Price memory matters. I use it every week. It keeps me honest.
But newer investors fall into a trap with it.
They think the spreadsheet is the whole story.
It's not even close.
NameBio shows you what sold and for how much. What it doesn't show is why that number happened. And the why is almost always where the real lesson is.
A sale is never just the name.
It's who the buyer was. How badly they needed it. Whether the seller had patience or got tired of waiting. Whether a broker was involved and knew how to create tension. Whether it was one clean deal or part of a portfolio move where the per-name math got messy.
You don't see any of that. You just see the number.
A $25,000 comp could mean a lot of things. Funded startup on a deadline. Defensive buy. Auction with two motivated bidders who drove each other up. Sometimes it's just luck and the timing lined up. NameBio doesn't know the difference and neither do you when you're using it as a baseline.
There's also a graveyard the data doesn't show you.
For every name that sells, thousands don't. They get renewed. And renewed again. No inbound. No offers. Nothing. The database records exits. It doesn't record the years of registration fees on names that looked like that $25,000 comp but never found a buyer.
That's survivorship bias. And in domain investing it's expensive.
I've bought names because the comps looked right. The category made sense. The keywords matched something that sold. And then nothing. Year after year. At some point you're not holding an asset, you're just paying rent on a bad decision.
The comps didn't tell me that was coming.
Two names can look identical in a spreadsheet and get completely different reactions from real buyers. Same length. Same extension. Similar keywords. But one sounds like a company and one sounds like a parked page and buyers feel that before they can even explain it. None of that fits in a filter.
Venue matters too. A sale in a curated marketplace after a broker campaign is a different animal than a cold outbound deal you ground out yourself. Auction heat is different from a quiet private transaction. The number might be the same. The circumstances usually aren't.
And negotiation skill skews comps more than people want to admit. Patient sellers anchor higher. They don't panic when it goes quiet. They know how to frame value. The price you're looking at might say as much about who sold it as what they sold.
None of that is in the data.
I don't have a clean way to wrap this up because, honestly, I don't think it's possible. NameBio is a tool. A good one. But it shows you outcomes, not reasons. And if you're trying to build real judgment about what names are worth and why deals happen, the data is a starting point, not an answer.
The rest you learn the slow way.
