How can I test entire page redesigns without slowing down my website?

You can test full page redesigns using edge-based redirection that happens in 0ms, meaning there is zero redirect latency and no flicker. This approach avoids the performance hit of client-side JavaScript that swaps content after the page loads. Seatext AI's Split URL Testing Agent uses this method, so you can run large-scale experiments without affecting your site's speed or Core Web Vitals.
