How to Check a Domain Before Buying It (DR, Age, Expiry and More)

A domain can look perfect for sale and still come with baggage: spammy backlinks, a penalty-worthy past, or a registration that's about to lapse. Before you pay for any domain, especially an aged or expired one, check a domain before buying it with these five free checks.

They take about five minutes in total, and they can save you from a very expensive mistake.

1. Check its Domain Rating

If you're paying extra because a domain "has authority", check that the authority is real. Domain Rating shows how strong its backlink profile is.

What to look for:

• DR 0–5: basically no backlink value. Only pay for the name itself.
• DR 10–30: some real links. Check where they come from (step 5).
• DR 30+: worth a closer look, but also the most likely to have been inflated with paid links before a sale.

Tip: compare the DR with the domain's age. A 2-year-old domain with DR 60 and no real website history is a red flag: someone probably built links just to sell it.

2. Check how old it really is

Sellers love saying "aged domain". The registration date tells you if it's true, and whether the domain has been dropped and re-registered (which resets the date).

Remember: age on its own isn't a ranking factor. Older domains tend to do well because they've had more time to earn links, not because of the date itself. So age only matters together with DR and history.

3. Check the expiry date and status

For a domain someone is selling you, check:

• When it expires. If it expires soon, make sure the transfer happens first, or that it's renewed as part of the sale.
• The registrar. You'll need to transfer it from there.
• Transfer lock. Domains are often locked against transfers; the seller has to unlock it.

What happens when a domain expires?

For common extensions like .com, a domain usually goes through these stages after its expiry date:

This is why "expired domains" for sale are often bought right as they drop. Country-code domains (like .in or .uk) can follow different rules.

4. Check what it was used for before

Open the domain in the Internet Archive's Wayback Machine and look through old snapshots. You're looking for:

• A totally different topic (a former casino or pill site will come with matching backlinks)
• Spam pages, auto-generated content or thousands of thin pages
• A real business or blog, which is the best case: real links earned for real reasons

Also search Google for site:thedomain.com. If a domain with a real history shows nothing at all, it may have been penalised in the past.

5. Check where its backlinks come from

A high DR is only good news if the links behind it are real. Using any backlink tool, check:

• Are the linking sites relevant to the topic you plan to use the domain for?
• Are they real websites with content and visitors, or link lists?
• Is the anchor text natural (brand name, URLs), or stuffed with keywords and spammy phrases?
• Did most links appear in a sudden burst just before the sale?

Bonus: test the speed of what's there

If you're buying a whole website (not just the domain), run its homepage through a speed test. A slow site needs work before it can rank well, and that's a cost to factor into the price.

How to check a domain before buying: the 5-minute checklist

1. Domain Rating: is the authority real and worth the price?
2. Age: is it really as old as claimed, or was it dropped and re-registered?
3. Expiry: when does it expire, who's the registrar, is it locked?
4. History: what did it look like in the Wayback Machine?
5. Backlinks: are the links relevant, natural and from real sites?

If a domain passes all five, you've found a good one. If it fails one, ask more questions. If it fails two, walk away.

Once you own it, add it to DomainRating.app: we'll track its DR every day and remind you 30 days and 7 days before it expires, so you never lose it by accident.
