Mistake: trusting last-click in a cookieless world
Everyone still credits the last cookie before checkout. Half those cookies are dead — Safari nukes them in 7 days, ad blockers eat them, users switch devices, and your network silently undercounts.

What actually happens:
— You drive a signup that takes 21 days to convert. Cookie expired at day 7. You get nothing.
— The program shows it as "direct" or hands credit to whoever touched last.

Fix: prefer programs with server-side tracking, longer cookie windows (45-90 days), and coupon/sub-ID attribution that survives cookie death. Use a unique discount code as a backup ledger you control. Reconcile your own click logs against their reported conversions monthly — a >15% gap is a tracking problem, not a traffic problem.

Verdict: if your attribution depends on a browser cookie in 2026, you're getting robbed and calling it a slow month.

Mistake: building a business on a "lifetime" commitment
Everyone loves "lifetime recurring." Read the terms: lifetime of the customer, or lifetime that the program decides to keep paying you — usually capped at 12 months, or revocable with 30 days' notice, or void if you go inactive.

The failure mode:
— You build a pillar page, rank it, and bank on years of passive payouts.
— Year two, they switch to a 12-month cap or get acquired, and your "lifetime" income flatlines.

Fix: screenshot the current terms, then assume a 12-month payout horizon for any planning. Never let one "lifetime" program exceed ~25% of your recurring income. Diversify across 4+ programs so a single terms change can't gut you.

Verdict: "lifetime" is their lifetime, not yours, and theirs ends whenever finance says so.

Mistake: spending every payout the day it lands
Everyone withdraws the full balance the moment the program approves it. Then a fraud sweep, a refund wave, or a quarterly true-up claws back more than this month's earnings — and now you owe them money.

How people get caught:
— A big launch cohort refunds at 25%.
— The reversal hits after you've already spent and scaled.
— Negative balance, paused payouts, scramble.

Fix: hold a clawback reserve. Park 20-30% of every payout for 90 days before you treat it as yours. Size the reserve to your worst historical reversal month, not your average. Boring, yes. It's also the difference between a cash crunch and a calm quarter.

Verdict: money the program can still take back was never your money.

Mistake: bragging about MRR you haven't kept
Everyone posts their recurring MRR screenshot. New MRR added is a vanity number. The only line that matters is net MRR after churn — and that one rarely makes the screenshot.

The self-deception:
— You add $2k of new recurring commission a month and feel like you're growing.
— Churn eats $1.6k of the existing base. Real growth: $400.
— You're sprinting to stand still and paying ad costs to do it.

Fix: track net MRR movement — new + reactivated − churned − contracted. If your churned line approaches your new line, you don't have a growth problem, you have a leak. Fix retention-side (content, audience fit) before buying more traffic.

Verdict: gross MRR is the number you post. Net MRR is the number that's actually in your bank.
