ROI (Return on Investment)

ROI is the ultimate measure of success in affiliate marketing and media buying. If you spend $1,000 on advertising and earn $1,500 in revenue, your ROI is 50%. In traffic arbitrage, experienced media buyers typically target 20-50% ROI on stable campaigns, while test campaigns may run at negative ROI initially. A common benchmark: a gambling campaign spending $5,000/day at 30% ROI generates $1,500 daily profit. However, ROI must be calculated against total costs — not just ad spend but also tools (tracker subscriptions at $50-$300/month), proxies, anti-detect browsers, creative production, and team salaries. Many beginners make the mistake of calculating ROI only against ad spend, which inflates the number. In real-world affiliate marketing careers, ROI targets are often set by team leads — solo buyers might aim for 40%+ ROI on smaller volumes, while team buyers scaling to $50,000+ daily spend may accept 15-20% ROI because the absolute profit is substantial. Job postings for media buyers frequently list "maintaining positive ROI while scaling budgets" as a key requirement. Tracking ROI daily and even hourly during scaling phases is standard practice, with automated rules to pause campaigns that drop below breakeven.
