The real cost of NOT using a CDN for affiliate traffic.

The real cost of NOT using a CDN for affiliate traffic.

Let's be specific about what slow load times actually cost.

Google's data: each additional second of mobile load time increases bounce rate by ~20%. For affiliate sites, a bounce before the user reads your content means zero chance of conversion.

Facebook's internal data (published via case studies): landing page load time directly impacts ad delivery. Slow pages get penalized in the auction, meaning you pay more per impression than competitors with faster pages — even at the same bid.

For Google Ads: Quality Score includes landing page experience, which factors in load speed. A poor Quality Score means higher CPCs. On competitive affiliate keywords, the difference between a 7/10 and 9/10 Quality Score can be $0.50-$2.00 per click.

If you're spending $5,000/month on paid traffic and your Quality Score is suppressed by page speed issues, you might be overpaying by $500-$1,500/month. A CDN that costs $20/month pays for itself in the first day.

The math is unambiguous. CDN is not optional infrastructure for anyone running paid affiliate campaigns.
