You can tell a real site owner from a link reseller by asking for things only the owner can do: reply from an address on the site's own domain, change something on the site within a day, or show the site's Search Console. Resellers usually can't, and they tend to offer long lists of unrelated sites without naming one before payment.
The usual situation: you get an email offering guest posts on "high-DA sites in your niche", with a spreadsheet of 300 domains attached. The sender's address is on Gmail. One of the sites looks good, but you have no idea whether this person runs it, knows the person who does, or has never spoken to either.
Why does it matter who you deal with?
It matters because a reseller adds cost and removes control. A reseller sits between you and the person who can actually publish, edit or remove your link, so they can't promise the link stays live, keeps its attributes, or survives an editor's clean-up. Some sell placements on sites they have no agreement with at all.
There is also a policy question in both cases. Google's spam policies list "buying or selling links for ranking purposes" as link spam, and Google asks that paid placements carry rel="sponsored", which it defines as the value for "advertisements or paid placements". Dealing with the owner at least lets you agree on that openly.
How to spot a link reseller
No single check is proof, but resellers fail several of these at once.
The email address isn't on the site's domain
Owners and editors usually write from an address on their own domain, such as editor@theirsite.com. A seller writing from a free webmail address about a site they "manage" deserves a follow-up: ask them to email you from the site's domain.
They offer dozens of unrelated sites
An owner usually runs one site or a small group in related topics. A list of hundreds of domains across finance, pets, travel and crypto at fixed prices is a reseller's inventory, often scraped from sites that accept paid posts.
They won't name the site before you pay
"DA 50 tech blog, $90" with no domain means you can't check traffic, relevance or indexing. Owners name their site in the first message because it is the thing they are selling.
They can't make a small change on request
Ask for something only someone with publishing access can do quickly: add a sentence to a page you name, or publish a draft with a phrase you pick. An owner can do it in a day. A reseller has to ask someone else, if they can at all.
The prices don't match the site
Ahrefs found in its study of paid link prices that guest posts averaged $77.80 across 180 sites pitched and niche edits $361.44 across 450 sites. A strong site offered far below that, or a weak site priced far above it, often points to a middleman.
There is no trace of the person on the site
Look for the seller's name on the About page, in author bylines or in the site's contact details. You can also look up registration data with ICANN's lookup tool, though many domains use privacy services, so a hidden record proves nothing on its own.
Reseller or owner: the checks side by side
Two or more answers in the right-hand column usually mean you are talking to a middleman.
| Check | Owner | Reseller |
|---|---|---|
| Email domain | The site's own domain | Free webmail or an agency domain |
| Number of sites | One or a few, related | Dozens to hundreds, unrelated |
| Site named up front | Yes | Only after payment |
| Small change on request | Done within a day | Delayed or refused |
| Search Console access | Can show it | Can't |
| Name on the site | Byline or About page | Nowhere |
What happens if you buy from a reseller?
Buying from a reseller usually means paying a markup for a link nobody is responsible for. Common outcomes: the post goes live and is removed weeks later when the real editor notices, the link is changed to nofollow, or the placement lands on a page buried where it never gets indexed. When that happens there is nobody with access to fix it.

How do link exchanges avoid the middleman?
In a link exchange, both sides should be the people who control their sites, because each one publishes the other's link. On Backlinkster, the link a member submits must be an article URL on their own domain, and each swap is verified by API. That doesn't replace judging the partner's site, which how to vet a link swap partner covers.
Frequently asked questions
How do I verify that someone owns a website?
Ask them to email you from an address on the site's domain, make a small change to a page you name, or show you the site's Google Search Console. Any one of those is hard for a non-owner to fake.
Are all link resellers scammers?
No. Some agencies have real agreements with publishers. The problem is that you can't easily tell which ones, and you lose direct contact with the person who controls your link.
Why do resellers send lists of hundreds of sites?
Because their product is the list. Many compile sites that accept paid posts and add a markup. Lists that wide rarely contain sites relevant to your niche.
Can a WHOIS lookup prove who owns a site?
Sometimes. ICANN's lookup tool shows registration data, but many domains use privacy services, so a hidden record isn't a red flag by itself. Combine it with an email from the site's domain.
Is it safer to buy links directly from the site owner?
It is more accountable, since the owner can fix or keep the link live. It doesn't change Google's policy: paid links for ranking purposes are link spam unless qualified with rel="sponsored".
