SaaS link building: how it works, what it costs, and what has changed

What SaaS link building is

Link building is the practice of getting other websites to link to yours. Search engines treat those links as votes, and increasingly so do AI answer engines deciding which products to name in a response. For a software company, the practical goal is narrower than it sounds: you are usually trying to make a handful of specific commercial pages authoritative enough to outrank incumbents.

That is the first thing that separates SaaS from most other categories. A local business builds links to a homepage. An ecommerce site builds to category pages. A SaaS company almost always needs them pointed at three page types that barely exist elsewhere: comparison pages (“X vs Y”), alternatives pages (“best X alternatives”) and integration pages. Those are where the buying intent sits, and they are the hardest pages to earn links to, because nobody links to a page whose purpose is to sell them something.

Why SaaS is different from every other link building category

Four structural differences change what a sensible programme looks like.

• Your competitors are also publishers. In most categories the people ranking are not building content full time. In SaaS, the companies you are competing with have content teams, and often have had them for years. The topical authority gap is real and it compounds.
• The money pages are unlinkable. Nobody voluntarily links to a pricing page. This is why so much SaaS link building routes authority through a blog or a free tool and relies on internal linking to move it where it is needed — and why an agency that only builds to your homepage is not solving your problem.
• Customer lifetime value sets the price. Agencies price against what a customer is worth to you. Above $12,000 LTV the market band is $800–$1,000+ per link; between $7,000 and $12,000 it is $600–$800. The same link genuinely costs different SaaS companies different amounts.
• AI citation has become a second objective. Being named in an AI answer depends heavily on being cited by sources those systems trust — news publishers, reference sites, and well-maintained comparison pages. That pushes value towards digital PR and away from guest posting.

What actually works

The honest summary of the current market: the tactics that work are the ones that are expensive and slow, and the tactics that are cheap and fast are being devalued faster than they are being bought.

That last figure deserves attention. Manual outreach — the labour-intensive approach of contacting publishers and persuading them a link is warranted — fell from 38.2% to 21.4% of link builders' main strategy in a single year. Something replaced it, and in most cases what replaced it is paid placement dressed in editorial language. When you are evaluating an agency, that is the single most useful thing to establish: what proportion of your links will involve a payment to the publisher.

The three approaches that hold up for SaaS are covered in detail on the services page: editorial placements for predictable volume, digital PR for authority and AI citation, and linkable assets for compounding returns. Most working programmes use two of the three.

Telling earned placements from bought ones

Almost every agency describes its links as editorial. The word has no agreed definition, so it tells you nothing on its own. Three questions do tell you something:

1. Does money change hands with the publisher? Not with the agency — with the site publishing the link. This is the question that separates the market, and a straight answer is reasonable to expect.
2. Would this page exist without your link in it? A genuine editorial placement sits in content that had a reason to exist anyway. A placement that exists to carry your link is a different product, whatever it is called.
3. Does the site have traffic independent of its link inventory? A publisher with no audience is selling access to Google, not to readers, and Google is increasingly good at noticing.

None of these make bought links automatically fatal — the practical risk is usually wasted budget rather than a manual action. But you should know which you are buying, because the two have very different half-lives. What the actual risk looks like.

How to measure whether it is working

Ranking position is a lagging indicator and a noisy one. Three measures give you a signal earlier.

• Referring domains to the target page, not to the domain. This is the number that moves rankings for the page you care about, and it is the one agencies are least keen to report on because it is harder to inflate.
• Live-link rate at 90 and 365 days. Given 66.5% historical link rot, a programme that does not re-check placements is losing inventory it already paid for.
• Median referring domain count of the top five results for your money term, tracked over time. If that number is climbing faster than yours, you are losing ground while appearing to make progress.

Expect four to six months before any of this shows clearly in rankings, longer in competitive categories. The realistic timeline sets out what to expect month by month, and what it means if nothing has moved by month six.
