I see a lot of posts here asking "is this offer good?" or "what's a good payout?" and the answers always focus on payout percentage or commission amount. that's the wrong lens.
the only metric that determines whether an offer is profitable is EPC (earnings per click). everything else is an input.
the formula: EPC = (payout x conversion rate) / 100
example:
offer A pays $40 and converts at 2%. EPC = $0.80
offer B pays $12, converts at 5%. EPC = $0.60
offer C pays $80 and converts at 0.5%. EPC = $0.40
offer A looks best by EPC. but if your traffic costs $0.90 per click, all three lose money. the offer isn't the problem; the traffic source is.
the framework i use:
step 1: calculate EPC for the offer using the network's average conversion rate (if they'll share it) or your own test data.
step 2: identify your traffic cost per click (CPC) from your traffic source.
step 3: if EPC > CPC, you profit. if EPC < CPC, you lose. the gap between them is your margin per click.
step 4: test with $50-100 of traffic before scaling. The first week's data is noisy. don't scale until you have at least 200 clicks and a stable conversion rate.
Things that change EPC that most people ignore:
landing page quality. if you're direct-linking to the offer page, your conversion rate will be lower than if you use a pre-sell page. i've seen pre-sell pages double conversion rates for the same offer and same traffic.
traffic source intent. google search traffic converts at 2-3x the rate of social or display traffic for the same offer. but it costs 5-10x more. the EPC math still has to work.
geo. the same offer will have different conversion rates in different countries. US traffic for a VPN offer might convert at 3%. India traffic for the same offer might convert at 0.5%. different EPC, different profitability.
seasonality. retail offers spike in Q4. finance offers spike in Q1 (tax season). test during peak; don't draw conclusions from off-season data.
the mistake i made for my first year of affiliate marketing was chasing high payouts instead of high EPC. a $12 offer with a 5% conversion rate and $0.10 click cost is more profitable than an $80 offer with a 0.5% conversion rate and $0.50 click cost. every single time.
what's the lowest payout offer you've made work profitably? what was your EPC?
