How I validate a niche in 48 hours before committing

How I validate a niche in 48 hours before committing

I once spent four months on a 'home barista' site before realizing the affiliate payouts were $4 a sale. Brutal math. Now no niche survives without passing a two-day gauntlet first.

— Hour 1: find the affiliate programs FIRST. If average commission is under $15 or under 4%, the niche has a revenue ceiling I won't enjoy. I check this before keywords now
— Hour 2-4: pull 30 keywords, confirm at least 15 have forums/Reddit/Quora ranking page one (proof Google will rank thin sites)
— Day 1 evening: read 20 buyer-intent SERPs. Are they all DR70+ brands? Pass. Mix of small blogs? Green light
— Day 2 morning: check Amazon/affiliate seasonality on Google Trends — I want a flat line, not a December spike I'll miss
— Day 2: write ONE test post, publish on a parked subdomain, see if it indexes in 72h

The 'survival knives' niche I almost picked died at hour 1 — $6 average commission. The 'standing desks' niche cleared everything: $40 average sale, weak SERPs.

The setback: I skipped the seasonality check once and launched a 'patio furniture' site in September. Watched it bloom and die by October.

The takeaway: Check the money math in the first hour, not the fourth month. Keywords are worthless if the commissions are.
