- [Website Redesign: How to Improve Conversions (Not Just Looks)](https://www.getdalton.com/blogs/website-redesign-improve-conversions.md) (2026-05-04): A website redesign focused on aesthetics rather than conversion optimization can destroy functionality that was already working—one of digital marketing's most expensive and avoidable mistakes.
- [Simpson's Paradox: The Statistical Trap That Ruins A/B Tests](https://www.getdalton.com/blogs/simpsons-paradox-ab-testing.md) (2026-04-14): Your A/B test shows Version B wins overall. Higher conversion rate, clear statistical significance. Time to ship. Then you segment the data. Version B loses on mobile. It loses on desktop too. It loses in every single segment. But it wins overall?
- [How to Do a CRO Audit: Step-by-Step Guide](https://www.getdalton.com/blogs/cro-audit-guide.md) (2026-04-14): This guide walks you through a complete conversion rate optimization audit, from data setup to actionable recommendations.

Instead of wasting half your traffic on losing variants and waiting weeks or months for significance, bandits continuously learn, reallocate traffic toward winners, and form the mathematical backbone of personalisation.
- [Why A/B Testing Is Broken (And What's Replacing It)](https://www.getdalton.com/blogs/ab-testing-is-broken.md) (2025-09-15): A/B testing promised scientific, data-driven optimisation—but for most businesses it’s slow, wasteful, and blind to real user behaviour. AI, bandit algorithms, and personalisation now enable continuous, self-improving websites that adapt in real time instead of waiting months for a single “winner.”
