User loginDomain buying checklist: history, trademarks, backlinks and spam
Check a domain before you pay: Wayback history, trademark conflicts, backlink profile, spam and penalties, DNS/email reputation, and ownership verification.
- Check the domain's past before you pay: history, trademarks, backlinks and mail reputation.
- The Wayback Machine takes two minutes and catches most problems.
- A trademark conflict can cost you the domain regardless of what you paid for it.
- Confirm you meet the eligibility rules of country-code extensions before agreeing a price.
- Verify that the seller controls the name — on a marketplace this check is already done.
A domain arrives with a history you inherit. Most of the time that history is uneventful, but the exceptions are expensive: a name once used for spam, or one that reproduces somebody's trademark, can cost far more than the purchase price. Everything below can be done in about half an hour.
1. What was on it before
Open web.archive.org and look at the snapshots year by year. You are looking for a pattern, not a single page.
- Good: years of a consistent real business, or no snapshots at all because the name was never developed.
- Investigate: a change of language or topic, which may simply be a resale.
- Bad: pages of unrelated links in several languages, pharmacy or gambling content that does not match the name, or long stretches of auto-generated text. Those are the signatures of a spam network.
A domain with a bad past is not always unusable, but it starts at a disadvantage that takes months of work to undo. Unless the name is exceptional, walking away is cheaper.
2. Trademark conflicts
This is the check that can cost you the whole purchase. Owning a domain grants no rights over the name: if it reproduces a registered mark in the same field of business, the holder can bring a UDRP or equivalent action and have the domain transferred away.
Search the EUIPO database for EU-wide marks and your national register — the UIBM in Italy — for the exact word, then for close variants, restricted to your industry classes. A word registered as a mark in an unrelated sector is usually not a problem; the same word in yours is. If the name is central to your brand, an hour with a trademark lawyer is worth more than any amount of guessing.
3. Links and search history
An older domain may carry inbound links, which can be an asset or a liability. Run the domain through a backlink tool and look at the profile rather than the number: links from real, topically related sites are worth having, while thousands of links from directories and comment spam are a sign of past manipulation.
Also check whether the name is flagged by Google Safe Browsing, and search for the domain in quotes to see what people said about it. A name with a public reputation problem arrives with baggage no redesign fixes.
4. Mail reputation
This one is regularly forgotten and it hurts. If a domain was used for bulk e-mail, it may appear on blocklists, and your first invoice or password reset will land in spam. Check the domain against the main public blocklists and look for leftover DNS records — an old SPF or DKIM entry pointing at an unfamiliar provider tells you it was used for sending.
5. Eligibility and technical status
| Check | Where | Why it matters |
|---|---|---|
| Expiry date | WHOIS | A name expiring in days complicates the transfer |
| Transfer lock | WHOIS status codes | Must be off before an auth-code transfer |
| 60-day post-transfer lock | Ask the seller | Blocks a further registrar transfer |
| Extension eligibility | Registry rules | .it and .eu require an eligible registrant |
For .it, the registrant must be resident or established in the EU, EEA, Switzerland, San Marino or Vatican City; the .it guide covers it. Establish this before negotiating, not after agreeing a price.
6. Does the seller actually control it?
In a private deal this is the fundamental question, and it is not answered by a screenshot. Ask the seller to prove control the way a marketplace would: add a specific DNS TXT record you choose, or place a file at a path you specify. Only somebody with real control can do either.
On Hot4Sales this check is already part of the listing process — every domain passes an automated DNS or file verification before it is published, which is one of the practical reasons to buy from a listing rather than from a cold e-mail. See how it works.
7. The name itself
Technical checks aside, spend five minutes on the name as a name. Say it on the phone and see whether the other person spells it correctly. Look for unintended readings when the words run together. Check the meaning in the languages of your markets. Search the exact string on social platforms to see whether the matching handles are free, because a domain without handles limits you later.
If you are still weighing a descriptive name against an invented one, brandable vs keyword domains covers the trade-off, and why short domains are worth more explains what you are paying for with length.
8. Price and payment
Sanity-check the price against comparable sales before you accept: our valuation guide covers the method and realistic ranges. Then decide how to pay. For a small purchase from a verified listing, direct settlement is normal. Above a few thousand euro or with an unknown counterparty, use escrow.
Whatever you agree, put it in writing before money moves: price, currency, who pays any escrow fee, transfer method, deadline and what happens if the transfer fails. Then follow the transfer guide, and do not confirm receipt until WHOIS shows you as the registrant.
How long should due diligence take?
About thirty minutes for a typical purchase: ten on the Wayback Machine and WHOIS, ten on trademarks, ten on backlinks and mail reputation. For a five-figure name, add a professional trademark search.
Is an old domain always better than a fresh one?
No. Age helps only when the history is clean and relevant. An old domain that hosted spam is worth less than a newly registered name, because you inherit the damage along with the age.
What if the seller refuses to prove control?
Walk away. Adding a DNS record or a file takes two minutes for a genuine owner. A refusal means either they do not control the domain or they are not the person they claim to be.
Do I need a lawyer to buy a domain?
Rarely, for a typical purchase. It is worth it when the name is central to a brand you are investing in, when the amount is significant, or when a trademark search turns up anything close to your intended use.
