The Most Misunderstood Metric in Domain Investing
New domain investors often ask:

“What sell-through rate should I expect?”
They usually hope the answer is:
- 10%
- 15%
- Or even higher
The reality is far less exciting—and far more sustainable.
Most profitable domain investors succeed despite low sell-through rates, not because of high ones.
Let’s look at the truth behind STR (Sell-Through Rate), why it’s lower than people expect, and why a low STR is not a failure.
1️⃣ What Sell-Through Rate Really Means
Sell-Through Rate (STR) is simple:
STR = (Domains Sold per Year ÷ Total Domains Held) × 100
If you hold:
- 100 domains
- And sell 1 domain per year
Your STR is 1%.
This number feels discouraging—until you understand how domain markets actually work.
2️⃣ The Real-World STR Most Investors Experience
Across independent portfolios, marketplace data, and long-term investor disclosures, the typical annual STR for buy-and-hold domain investors falls between:
- 0.5% – 2% per year
Yes, that’s normal.
A 1% STR means:
- 99 domains don’t sell this year
- But the 1 sale often covers renewals for many years
Domain investing is power-law driven:
a small number of sales produce the majority of profit.
3️⃣ Why STR Is Naturally Low in Domains
Domains are not consumable products.
They are:
- One-buyer assets
- Bought once
- Only when a specific business event occurs
Unlike software subscriptions or retail goods:
- There is no recurring demand
- There is no impulse buying
- There is no volume cycle
Each domain waits for its one buyer.
That structural reality caps STR by design.
4️⃣ Why Low STR Does Not Mean Low Profitability
Let’s look at a realistic example.
Portfolio:
- 100 domains
- Average cost: $10 registration + $10 annual renewal
Annual holding cost:
- ~$1,000
If you sell:
- 1 domain at $3,000
You are:
- Profitable
- Cash-flow positive
- Able to renew selectively
- Compounding inventory quality
That is a 1% STR producing profit.
High STR is not the goal.
Positive expectancy is.
5️⃣ Why High STR Portfolios Usually Have Low Margins
Some portfolios do achieve:
- 5%–10% STR
But this usually happens when:
- Domains are priced at $99–$499
- Inventory is commodity-grade
- Volume is prioritized over quality
The result:
- More sales
- Lower profit per sale
- Higher churn
- Less pricing power
High STR feels good emotionally.
Low STR with high margins works financially.
6️⃣ The Time Factor Most People Ignore
STR is annual, but domains are multi-year assets.
A domain that sells in year 4:
- Had a 0% STR for three years
- Then suddenly becomes a 100% success
Judging domains on 6–12 month windows leads to:
- Premature drops
- Missed exits
- Portfolio underperformance
Domains don’t expire in relevance the way ads or trends do.
7️⃣ What STR You Should Actually Target
Healthy targets for serious investors:
- 0.5% – 1% → Conservative, low-stress
- 1% – 2% → Strong, sustainable
- 2%+ → Exceptional (usually niche or premium)
Anything above this often comes with:
- Pricing sacrifices
- Inventory dilution
- More management overhead
8️⃣ Better Metrics Than STR Alone
Instead of obsessing over STR, track:
- Average sale price
- Renewal burn rate
- Portfolio cash-flow breakeven
- Buyer quality (end user vs reseller)
- Time-to-sale distribution
STR without context is misleading.
🔑 Investor Takeaway
A low sell-through rate is not a weakness. It’s the natural shape of the market.
Domain investing rewards:
- Patience over activity
- Quality over quantity
- Timing over discounts
If your portfolio:
- Is commercially logical
- Targets real buyer pools
- Is priced rationally
Then a 1% STR is not failure.
It’s how the game is designed.
