Which Scales Better for SaaS?
-
Affiliate Marketing: Scales organically once you have a network of affiliates. Growth compounds as affiliates continue to generate recurring customers. Best for sustainable, cost-efficient scaling.
-
Paid Ads: Scales instantly with budget but has diminishing returns. Great for short-term boosts or testing messaging, but less sustainable in competitive SaaS niches.
Verdict: For B2B SaaS, affiliate marketing generally scales better long-term due to lower CAC and higher trust. Paid ads work best as a complementary channel for speed and experimentation.
When to Use Each Channel
-
Early stage SaaS: Start with referral programs, then test paid ads for quick validation.
-
Growth stage SaaS: Add affiliates for compounding reach while maintaining some paid ads for pipeline acceleration.
-
Mature SaaS: Run both—affiliates for sustainable CAC, ads for competitive presence.
Best Practices for Combining Both
-
Use paid ads to attract affiliates (e.g., target “become a SaaS affiliate” keywords).
-
Provide affiliates with battle-tested landing pages optimized from your paid ad experiments.
-
Compare CAC from affiliates vs paid ads monthly and adjust spend accordingly.
FAQ – Affiliate vs Paid Ads
Q: Which is cheaper for SaaS, affiliates or ads?
A: Affiliates. You pay commissions only after revenue, whereas ads require upfront budget regardless of results.
Q: Do affiliates replace paid ads completely?
A: Not always. Many SaaS companies use affiliates for scale and ads for speed or brand presence.
Q: Which works better for B2B SaaS specifically?
A: Affiliates—because trust and niche authority matter more in B2B buying cycles.
Q: Can I start both at the same time?
A: Yes, but ensure you have the resources to manage affiliates. Otherwise, start with paid ads for testing and add affiliates once PMF is clear.
