What it costs

-
Cost data
How much does SaaS link building cost in 2026?
The number nobody in this market will publish, assembled from the people who do research it. Per link, per month, and by category — with sources for all of it.
-
Cost data
What is a fair price per backlink in 2026?
A single number to anchor every quote you receive, plus the bands underneath it and the point below which you stop buying links and start buying inventory.
-

Why do link building agencies not publish their pricing?
Eight of the twelve agencies we document publish no rate at all. Some of the reasons are perfectly sound. Here is how to tell which is which, and how to price anyway.
-
Cost data
What should a $5,000 a month link building retainer actually deliver?
The most common SaaS budget in this market, and the least specified. Here is what that money should buy at published rates, and what tends to go missing.
-

How do I calculate ROI on a link building retainer?
The calculation is straightforward. What makes it hard is that the payback lands two quarters after the invoice, and a third of the asset expires.
Contracts and risk

-
Contract check
What are the red flags when hiring a link building agency?
Most of these are visible on the first call if you know what to listen for. One of them cannot be talked around at all.
-
Contract check
What questions should I ask on the first sales call?
Ask all eleven, in the same order, of everyone. Identical questions produce comparable answers — which is the thing proposals in this market are missing.
-
Contract check
How do I vet a link building agency before signing?
Five stages, roughly two weeks, and a small paid trial at the end. Cheaper than discovering the problem in month four.
-
Contract check
What should I check in a link building contract?
Link building contracts are short, which is not the same as simple. These are the seven points where the difference between engagements is actually written down.
-
Contract check
Can buying links get my SaaS penalised by Google?
The risk is real and almost always mispriced in sales conversations — in both directions. Here is what actually happens.
-
Contract check
Who owns the links if I cancel the retainer?
Live links stay live and nobody can take them back. Almost everything else depends on a clause most contracts leave out.
-
Contract check
What happens when the links you paid for go dead?
Two thirds of everything ever built is gone. It is the least discussed line item in link building and the easiest one to negotiate for.
Decisions and comparisons

-
Decision guide
Is link building cheaper in-house or through an agency?
One in-house specialist costs about $7,300 a month before tools. Here is what that actually buys against an agency retainer, and where the crossover sits.
-
Decision guide
What Domain Rating should I be targeting?
DR is the metric everyone quotes and the easiest one to game. Here is what to use instead, and what DR is still good for.
-
Decision guide
Guest posts or digital PR — which should a SaaS buy?
One is cheap, fast and predictable. The other is expensive, slow and unpredictable — and worth more per link. The choice is mostly about which risk you can carry.
-
Decision guide
Niche edits or guest posts — is either one safe?
Both are paid placements with different labels. The useful question is not which is safe, but what each is actually worth at its price.
-
Decision guide
Do links still matter now that buyers use AI search?
They matter more, not less — but the links that earn AI citations are not always the ones that move classic rankings.
-
Decision guide
Agency, marketplace or freelancer — which should you use?
Three routes to the same outcome, with completely different failure modes. The right one depends less on budget than on who is going to enforce quality.
Timelines and expectations

Timeline
How long before link building affects rankings?
Four to six months is the honest answer, and the months before that are not empty. Here is what should be happening in each one.
-
Decision guide
