What the publisher is actually paid
Start with the number almost nobody puts on a pricing page: what the site owner receives. PressWhizz published transaction data across 22,703 completed placements on its own marketplace, about $3.66m of volume, and the median price paid was $112, with an average of $161 [1].
Adsy analysed 52,671 sites and found publishers ask $929 on average while buyers typically pay $207 [2]. That is a gap of more than four times between the list price and the transacted price, which tells you something important about this market: there is no fixed price, only what you negotiate.
BuzzStream, working from a database of over 500,000 guest post sites, put the average direct-from-publisher guest post at $295, and the average link insertion into an existing page at $179 [3][4]. An older Ahrefs study that approached 450 sites directly found an average of $361 for a niche edit and $77.80 for a pitched guest post [5].
What agencies charge for the same placements
Published rate cards, read off each agency's own pricing page in August 2026, run from $2,999 a month for 7 to 8 links up to $15,000 a month for 28. Per link, that works out at roughly $210 to $536.
Some agencies print the per-link figure themselves. Editorial.Link lists a flat $375 per backlink [6]. OneLittleWeb prints an average of $428.43 on its $2,999 tier. uSERP values a DR 60+ link at $600 to $900 on its own pricing page [7]. One prominent agency founder puts the typical market range at $500 to $1,250 per link.
None of this is hidden. It is just never shown next to the publisher-side numbers above.
The honest size of the gap
There is exactly one published like-for-like comparison of the same placement bought both ways. BuzzStream found the same guest post costs $295 direct from the publisher and $461 through a vendor, a 56% uplift [3]. That is the measured spread, and it is defensible: the vendor found the site, wrote the post and handled the publishing.
The retainer is where the number stops being checkable. A $2,999 package delivering seven links is $428 each, against a publisher fee that transaction data puts nearer $112 to $295. Some of that difference is real work. Some of it is markup on the placement fee. No retainer we could find discloses the split, and we went looking for a published figure on what share of an agency fee reaches the publisher. The only claim we found was an unsupported one from a publisher network, so we are not using it. Nobody measures this, which is rather the point.
Why the work is still worth paying for
This is not an argument that link building should be free. BuzzStream filtered its 500,000-site database on real authority and traffic and 1.37% of it survived [8]. Finding the sites worth buying from is most of the job.
Pricing is also wildly inconsistent between sellers. LinkPricer found the identical domain sells for 147% more on the most expensive marketplace than the cheapest, and 40% of domains listed in more than one place differ in price by over 100% [9]. There is no market price. The negotiation is the product.
So the objection is not that agencies charge for work. It is that you cannot see which part of the bill bought a link and which part bought the work.
How to buy links without flying blind
Ask for the split. An agency that passes placement fees through at cost, with the publisher's quote attached, has nothing to hide and will show you. One that quotes a single bundled number is asking you to take the markup on trust.
Judge price per point of authority, not per link. A $30 link on a weak site can cost more per point of Domain Rating than a $100 link on a strong one, so the per-link price alone tells you very little.
And treat every figure in this article the way we treated its sources: as dated. Rates move. Check the source before you quote it.
