How to buy SaaS link building without getting taken
Judge the agency the way you would judge a link
An agency that sells authority ought to have some. It is the least generous test available, and it is striking how many struggle with it. Across the 26 agencies tracked here the median Domain Rating is 63, which is respectable. Their own organic traffic is another matter: 17 of 26 lost search traffic over the last twelve months, and the median change was -50%.
That is not automatically disqualifying. An agency can be excellent at client work while neglecting its own blog, and several here are demonstrably both. But it reframes the sales call. When someone tells you they can grow your search visibility, it is fair to ask what happened to theirs, and fairer still to ask before you have spent an hour on a call.
What the money actually buys
Published per-link prices in this set run from $37 to $528, and monthly packages from $697 to $19,999. The tiers are real and they mean fairly consistent things.
Below $100 a link you are buying placement volume on sites with modest authority, usually through an established publisher network rather than fresh outreach. It works for building a baseline and it is where most white-label fulfilment sits. Between $100 and $250 you are paying for a higher authority floor and content someone actually edited. Between $250 and $400, which is where most retainers land once you divide the monthly fee by the links it includes, you are buying genuine outreach and a named person who answers email. Above $600 a link you are buying editorial placements on sites with real editors, and the cost is mostly the pitching, not the publishing.
The one thing worth internalising: within this dataset there is no reliable relationship between what an agency charges and how much authority it has itself. The cheapest published price in the set belongs to an agency with a Domain Rating of 73. Price signals positioning, not quality.
Five things that should slow you down
A quality floor stated in a metric the agency picked. Some publish a floor in Ahrefs DR, some in Moz DA, one in the publisher's referring-domain count. These are not interchangeable, and a floor is only meaningful once you know which scale it is on. 14 of 26 agencies publish a floor at all.
A guarantee that expires at publication. At least one agency here states plainly that metrics are validated only at the moment the link goes live, with no lifespan guarantee and replacements billed as new orders. That is a legitimate way to run a business and it is admirably clear, but it is the opposite of what most buyers assume a guarantee means.
Pricing that only exists after a call. 13 of 26 agencies publish nothing. Sometimes that reflects genuinely bespoke work. Sometimes it means the price depends on what you look like you can pay.
Client logos that are actually publications. More than one agency in this set displays CNN, Forbes and the BBC on its homepage. Those are places they have placed links, not companies that have hired them. Read the heading above the logo wall.
Reporting you cannot audit. Ask whether you will receive live URLs, and whether the agency re-checks the metrics it sold you against after placement. Most do not.
Four questions worth asking on the call
Which metric is your quality floor measured in, and what happens if a placement lands below it? What is your replacement policy after the link goes live, in months? Can you show me three live URLs from the last quarter in a vertical like mine? And what has your own organic traffic done this year?
The last one is not a gotcha. Everyone in this market had a difficult year, and an agency that answers it straight is telling you something useful about how it will report on yours.
