What is Ad Arbitrage? (Explain Like I'm 5)
Imagine you have a lemonade stand. You pay $1 to get customers to come to your stand (that's the cost of buying traffic). When they arrive, you show them ads for other businesses and earn $1.50 (that's display ad revenue). You keep the $0.50 difference as profit.
That's ad arbitrage in a nutshell. You're the middleman between people searching for information and advertisers who want to reach those people.
The Simple Formula
If your ad revenue is higher than your traffic cost, you make money.
How Ad Arbitrage Works
Find a Profitable Niche
Look for topics where display ads pay well (high RPM) but traffic is cheap to buy (low CPC). Finance, health, and technology niches often work well. Use tools to analyze margins before spending.
Create Content
Build pages that match what people are searching for. The content needs to be valuable enough that visitors stay and see the ads. Listicles, how-to guides, and comparison articles work well.
Buy Traffic
Run ads on Facebook, Google, or native ad networks to send visitors to your pages. Start with small budgets ($10-50/day) to test which ads and audiences convert best.
Monetize with Display Ads
Show ads from networks like Google AdSense, Ezoic, or Mediavine. These ads pay you based on impressions (CPM) or clicks. The key is earning more than you spent on traffic.
Scale What Works
Once you find a profitable combination, increase your ad spend gradually. Monitor margins closely—what works at $50/day might not work at $500/day due to increased competition.

Ad Arbitrage vs Affiliate Marketing
| Aspect | Ad Arbitrage | Affiliate Marketing |
|---|---|---|
| How you earn | Display ad impressions/clicks | Commission on sales/leads |
| Revenue timing | Immediate (per visit) | Delayed (after conversion) |
| Typical margins | 20-50% | Varies widely (5-50%) |
| Complexity | Lower (just drive traffic) | Higher (need conversions) |
| Scaling | Easier to scale quickly | Depends on offer caps |
Many publishers combine both strategies—earning from display ads while also including affiliate links for products mentioned in their content. This maximizes revenue per visitor.
