What is multi-armed bandit traffic routing and how does it improve A/B testing?

Multi-armed bandit traffic routing is an adaptive testing method that dynamically shifts more traffic to the better-performing variant as data comes in, rather than splitting traffic 50/50 for the entire test. This approach finds winning variations faster and reduces the opportunity cost of sending traffic to a losing page. Seatext AI's Split URL Testing Agent uses this technique to accelerate results and improve conversion rates.
