Two link-building vendors can do almost identical work and bill you in completely different ways. One charges a fixed monthly retainer. The other only charges for the links that actually go live. Same links, very different risk.
Picking the wrong model is how buyers end up paying for months of “activity” with little to show for it. Here is how each one works, who carries the risk, and how to choose.
What you’ll learn
- How a link-building retainer actually works
- How performance-based (pay-per-live-link) pricing works
- Who carries the delivery risk in each
- What each model really costs
- How to choose the one that fits your situation
How a link-building retainer works
A retainer is a fixed monthly fee for an agreed scope of work. You might pay $2,000 to $10,000 a month, and the agency runs outreach, content, and strategy against that budget.
The upside is predictability and breadth: a good retainer covers strategy, content, and digital PR, not just raw link placement. The downside is where the risk sits. You pay the same invoice whether the month produced eight strong links or two weak ones. You are buying the agency’s time, and the result is your problem.
How performance-based link building works
Performance-based pricing, usually sold as pay-per-live-link, flips that. You approve target sites, the team does outreach, you pay upfront, and any link not confirmed live is refunded pro-rata. No live link, fully refunded.
The upside is that the vendor carries the delivery risk. Their incentive matches yours: real placements on sites you approved. The trade-off is a higher price per individual link, because your money is tied to a result instead of effort.
The two models, side by side
| Factor | Link-building retainer | Performance-based (pay-per-live-link) |
|---|---|---|
| What you pay for | The agency’s time and effort | Only links that go live |
| Who carries risk | You | The vendor |
| Cost predictability | Fixed monthly fee | Per-result, scales with output |
| Price per link | Lower on paper | Higher per link, often lower cost-per-result |
| Typical scope | Strategy, content, PR, links | Link placement |
| Best for | Ongoing programs, broad scope | Buyers who want links that actually land |
What each really costs
Per link, a retainer can look cheaper. But the honest number is cost per live link, and that depends entirely on how many links the retainer produces. A 2023 Authority Hacker survey of more than 750 link builders put the average paid link around $83, but a retainer bills you for the outreach whether or not links at that value ever appear.
Performance pricing usually costs more per link and less per disappointment. You never pay for the month where nothing landed. For a full breakdown of ranges and what drives them, see how much backlinks cost.
How to choose
Pick a retainer when you want a fixed monthly spend, a broad scope that includes strategy and content, and an ongoing relationship where links are one part of a bigger program.
Pick performance-based when you specifically want links that go live, you have been burned by a retainer that underdelivered, or you want the vendor to carry the delivery risk. If your main question is “how many good links will this actually produce,” performance pricing answers it honestly.
Whichever you choose, the safety of the links comes from the same place: relevance, real editorial placement, and your approval of every target. Vet the vendor before the model. Our 9 red flags for vetting an agency apply to both.
Frequently asked questions
Is a retainer or pay-per-live-link cheaper?
Per link, a retainer often looks cheaper. Per live link, it depends on how much the retainer actually produces. Performance pricing costs more per link but you never pay for a month with no results.
Does a retainer guarantee links?
No. A standard retainer pays for the agency's time and effort, not a set number of live links. Read the scope carefully; guaranteed deliverables are the exception, not the rule.
Is performance-based link building safe?
The pricing model is neutral. Safety comes from the links being editorial placements on real, relevant sites you approved, not from how you are billed.
Which model is better for a small business?
Most small buyers who want a predictable cost-per-result and cannot absorb a wasted retainer month are better served by pay-per-live-link. Larger programs that need strategy and content may prefer a retainer.
Wrapping up
A retainer buys effort and breadth. Performance-based pricing buys outcomes and moves the delivery risk onto the vendor. Neither is automatically better, but only one bills you for links that never showed up. Decide who should carry that risk, then pick the model that puts it there.
