If you rank affiliate niches by earnings per referral, software wins comfortably. It's also the niche where the gap between good and bad execution is widest.
Why the economics are so good
Subscriptions retain. A business that embeds a tool in its daily workflow doesn't casually switch. Multi-year customer lifetimes are normal, which makes recurring commissions genuinely valuable rather than theoretically valuable.
Prices are high and rise over time. Business software is priced per seat, and successful customers add seats. A recurring commission on an account that grows from five to fifty seats grows with it.
Margins fund generous commissions. Software has near-zero marginal cost, so companies can pay 20–30% recurring and still profit — rates that would be impossible in retail.
Cookie windows tend to be longer. B2B buying involves evaluation, trials and approvals. Software programs generally acknowledge this with longer windows than consumer products.
Why it's harder than it looks
The audience is small and expensive to reach. "Best CRM for small business" has far less search volume than "best running shoes", and every competitor is a well-funded content team.
Buyers are sophisticated. Software buyers read documentation, compare pricing pages, and try free tiers. Thin content that hasn't actually used the product is transparent to them and converts poorly.
Free tiers absorb conversions. Many tools have generous free plans. Your referral signs up, uses the free tier for eight months, and upgrades long after your cookie has expired.
The competition is entrenched. Established review sites have years of domain authority and dedicated teams. Ranking for head terms is a multi-year project.
Where the opportunity actually is
Long-tail, specific queries. "Best CRM" is unwinnable. "Best CRM for independent insurance brokers" is winnable, and the person searching it is far closer to buying.
Integration and workflow content. "How to connect X to Y" pulls in people already using one tool and shopping for the other. Low competition, high intent.
Migration guides. "Moving from X to Y" reaches people actively switching — the single highest-intent moment in software buying.
Honest comparisons that name a loser. Content that says "choose X if you need this, Y if you need that, and neither if you need this other thing" outperforms content that says everything is great. Readers can tell the difference, and so increasingly can search engines.
Categories where you have real expertise. If you've run payroll, or managed a support desk, or built with a particular stack, that experience is the moat. It cannot be replicated by someone assembling a listicle from marketing pages.
What to check before promoting a SaaS program
- Does recurring actually mean lifetime? Many programs cap at 12 or 24 months. That is a completely different proposition.
- What triggers the commission? Trial start, paid conversion, or first invoice paid. The difference is large.
- How are upgrades treated? Ideally your commission scales with the account. Some programs fix it at the initial plan.
- Is there a refund clawback period? Standard, but the length varies.
- Are annual plans paid up front? A year's commission in one payment is meaningfully better than twelve monthly ones.
- Who owns the customer on renewal? Some programs stop paying if the customer contacts sales directly.
A realistic path in
Pick one narrow area you genuinely understand. Publish deeply about it — comparisons, migration guides, integration walkthroughs, honest reviews of the tools you've actually used. Build enough traffic that advertisers take you seriously. Then apply.
That's slower than publishing fifty listicles, and it's the only version that works now that every generic roundup has already been written a hundred times.
