Most affiliate program reviews on the internet rank programs by gut feel. We did the math instead.
For the past several months, we've been collecting data on every program in our directory — commission rate, cookie duration, payment methods, minimum payout, and how complete the program's affiliate-facing documentation is. Then we scored all 164 active programs on a 100-point scale and looked at what separates the best from the rest.
The gap between the top 10% and everyone else is bigger than we expected — and the patterns are clear enough that they should change how you pick your next program.
The Quick Take
Top 10% of programs (17 of 164) beat the overall average by:
- ~3x higher commission rates — 70% average for the top 10% vs 25% average overall, when measured in percentage terms
- ~3x higher flat-fee commissions — $158 average for the top 10% vs $55 average overall
- ~2x longer cookies — 97 days average vs 44 days average
The top performers cluster in just a few categories, almost all support PayPal, and they're roughly evenly split between major affiliate networks and in-house programs. Here's the full breakdown.
How We Scored Them
Every program in our database is scored on five factors:
- Commission rate — 40 points
- Cookie duration — 20 points
- Minimum payout — 15 points
- Payment method diversity — 10 points
- Listing completeness — 15 points
No program pays to rank higher. The scoring formula is public and runs the same way against every program. To make the top 10% (a score of 76 or higher), a program needs to be strong on at least four of the five factors — being great at one thing isn't enough to make up for being mediocre at the rest.
We pulled the data on a recent snapshot of 164 active programs across 15 categories.
Pattern 1: Commission Rates Are Wildly Different at the Top
This was the most dramatic finding.
The average percentage-based commission across all 164 programs is 25.3%. Among the top 10%, that average jumps to 70.3% — nearly triple. Several top performers offer 100% of the first month or 50% of the first year as a kind of acquisition bonus that most programs don't.
For flat-fee programs, the gap is similar:
- Overall average: $55 per signup
- Top 10% average: $158 per signup
The takeaway isn't "chase the highest commission percentage" — it's that the top programs are systematically built to overpay on the first conversion in exchange for the lifetime value of the customer they're acquiring. If a program is paying you $200 for a signup, they've done the math and know that customer is worth $1,500+ over their lifetime. That's a signal of product-market fit you can trust.
Pattern 2: Cookies Are Twice as Long
Industry standard cookie duration is 30 days — and it's the most common value in our data (87 of 164 programs use exactly 30 days). But the top performers run longer:
- Overall average: 44 days
- Top 10% average: 97 days
- Most common in top 10%: 90 or 120 days
A few top programs push to 180 days. WP Engine, HubSpot, and a handful of others trust their funnels enough to give affiliates almost six months of attribution window.
This matters for one specific reason: the higher the price of the product, the longer the buying cycle. A 30-day cookie kills attribution on $300+ purchases that take weeks of research. The top 10% know this and adjust accordingly.
If you're picking between two otherwise similar programs and one has a 90-day cookie and the other has a 30-day cookie, the longer cookie is worth roughly 2x more in expected commission, even though the headline rate might be identical.
Pattern 3: B2B and SaaS Categories Dominate
Here's how the top 10% breaks down by category:
- Website Builders — 4 programs
- Marketing Tools — 4 programs
- SaaS & Software — 3 programs
- Finance & Fintech — 2 programs
- Web Hosting — 2 programs
- E-commerce — 1 program
- Education & Courses — 1 program
Thirteen of the top 17 sit in B2B SaaS-adjacent categories. Consumer categories like Fashion, Gaming, Food & Beverage, and Health & Fitness produced zero top-10% finishers in our data.
The explanation is the economics. B2B SaaS products have high lifetime value, recurring revenue, and customer acquisition costs that can sustain generous affiliate payouts. Consumer products usually can't — margins are thinner, repeat purchase rates are lower, and customer LTV is bounded by what someone will pay for a $40 t-shirt or a $20 supplement bottle.
If you're starting out and trying to choose a niche, the math overwhelmingly favors B2B over B2C.
Pattern 4: Percentage Beats Flat (Slightly)
In the full directory, percentage-based commissions outnumber flat-fee commissions about 2-to-1 (105 vs 40). The top 10% follows the same pattern: 10 percentage-based, 5 flat-fee, 2 hybrid.
But the more useful insight is what's missing: only one tiered-commission program made the top 10%. Tiered programs (where commission rates increase as you drive more sales) sound great in theory, but they tend to under-deliver in practice because most affiliates never hit the bonus tiers — so the headline "up to 50%" is misleading for everyone but a handful of super-affiliates.
The top 10% favor structures where the rate you see is the rate you get from your first sale.
Pattern 5: Network Choice Matters Less Than You'd Think
A common bit of advice is that affiliate networks like Impact, ShareASale, and CJ Affiliate filter for quality. Our data tells a more nuanced story.
Of the top 17 programs:
- In-house programs (no network): 7
- Impact: 6
- ShareASale: 2
- CJ Affiliate: 1
- PartnerStack: 1
In-house programs are tied for the largest share. The pattern isn't "join a network" — it's that well-run programs are well-run regardless of their plumbing. A great in-house program (like Notion or WP Engine) outperforms a mediocre network program every time.
The practical advice: don't filter out in-house programs just because they require an extra signup step.
Pattern 6: PayPal Is Effectively Universal
Across the top 17 programs, 15 support PayPal. Direct Deposit / ACH comes second at 11. Everything else (wire transfer, Stripe, crypto, check) appears in single digits.
If you don't have a PayPal account set up, you're locking yourself out of the highest-paying programs. This is the single easiest action item from this analysis — it takes 10 minutes and unlocks 90%+ of the top-paying programs in our directory.
Pattern 7: Listing Completeness Is a Quality Signal
This one is more subtle. The 15 points we allocate for "listing completeness" measure how thorough the program's affiliate-facing documentation is — whether they publish clear payment terms, list their cookie duration, document their approval process, and so on.
Programs in the top 10% almost universally score high on this. Programs in the bottom 25% almost universally score low. The correlation is strong enough that listing thoroughness is a reliable proxy for program operational quality.
When a program can't be bothered to clearly document its commission structure on its affiliate page, it usually also can't be bothered to pay on time, respond to support tickets, or update its terms when policies change. Skip them.
The One Counterintuitive Finding
One stat surprised us: "Featured" status doesn't correlate with the top 10%. Among the 17 top-scoring programs, only 3 are paying for featured placement on our directory.
This is by design — featured listings are a paid product, not an editorial endorsement. But it's worth saying explicitly: if you want the best programs, don't shop by the badges, shop by the score. The full ranked list is always available without paid placement bias.
What This Means for How You Pick Programs
Four practical takeaways:
1. Filter by cookie duration first. Anything under 30 days is a red flag unless the product is a $10 impulse buy. Top performers run 90 days or longer.
2. Bias toward B2B SaaS if you're building from scratch. The economics are simply better. A B2B affiliate site can earn 5–10x what an equivalent-traffic consumer site earns.
3. Set up PayPal before you set up anything else. It's the universal payment method for the top programs.
4. Treat commission rate as a quality signal, not a comparison metric. A 70% commission isn't "better" than a 20% commission — it tells you the company has high LTV and trusts its funnel. Use that as a filter, then optimize for everything else.

If you want our take on individual categories, the SaaS, Marketing Tools, and Web Hosting lists are good starting points — those are the three categories where the top 10% are concentrated.
The affiliate marketers who consistently outperform aren't the ones who pick the program with the flashiest headline rate. They're the ones who pick programs the data says will pay them more, longer, and more reliably. The patterns in this post are the framework they're using — whether they know it or not.
