Why traditional split URL testing wastes up to 50% of your ad spend
Legacy testing tools force a static 50/50 traffic split for weeks, sending thousands of paid ad clicks to losing variations while stripping critical tracking tags.

Frequently asked questions about Split URL testing
Clear explanations on zero-flicker URL redirection, SEO safety, cookie stickiness, and AI traffic optimization.
How does Seatext eliminate redirection flicker?
When a visitor navigates to your base page, the fast edge script evaluates active experiments and assigns the variant instantly before DOM content renders.
It executes a window.location.replace while preserving cookies and query markers, preventing any flash of the original page.
Will split redirection hurt my Google SEO rankings?
No. Split URL testing is a standard Google-approved practice.
Search engine crawlers (Googlebot) are served the original canonical page without redirection, while human visitors are assigned sticky test variants.
What happens to returning visitors?
Every assigned visitor receives a 30-day sticky cookie (st_ab_exp_{id}).
When they return or navigate back to the base URL, they are consistently shown their assigned variant, preventing loop glitches or conflicting pricing experiences.
How does the AI Dynamic Optimizer work?
Instead of waiting for a 50/50 test to finish across all users, our contextual Multi-Armed Bandit groups visitors by device (mobile vs desktop), ad channel (Google, Meta, TikTok), and geography.
As soon as a variant demonstrates higher conversion rates for a cohort, traffic is shifted dynamically toward that winner.
