Growth trends to watch

• Privacy-first experimentation: GDPR expectations and consent mode v2 push teams toward server-side testing, better consent capture, and robust data quality checks. Expect more collaboration between CRO and legal or privacy engineers.
• GA4 and server-side tagging: Companies are strengthening measurement foundations and QA to ensure experiment readouts are trustworthy, especially across web and app.
• Beyond web funnels: Product-led growth and subscription models drive tests in onboarding, pricing, and retention, not just checkout. Mobile app and in-product experiments are gaining share.
• AI-assisted CRO: Teams are trialing AI for copy variants, user research synthesis, opportunity scoring, and anomaly detection. The best results come when AI augments, not replaces, human insight.
• Personalization with restraint: More rules plus ML tactics for higher LTV segments, yet careful to avoid overfitting and consent pitfalls.

Key challenges facing service providers

• Sample size and velocity. Many Dutch sites have modest traffic. Providers must use sequential testing, CUPED, or Bayesian approaches, and prioritize higher-signal bets to reach decisions faster.
• Data trust. Consent drop-off, ITP, and ad blockers introduce bias. Strong partners invest in experiment QA, guardrail metrics, and data-layer hygiene before touching a single button color.
• Culture and processes. Without executive buy-in and engineering bandwidth, roadmaps stall. Agencies that embed with product and dev teams win. Those that sell CRO as a one-off tactic struggle.
• Platform complexity. SPA frameworks, headless CMS, and app stores complicate rollout and measurement. More server-side, more feature flags, more governance. -
• Tool sprawl. It is easy to overbuy. A tiny critique here: some providers still lead with tools instead of hypothesis-driven discipline and customer insight.

If you are shortlisting providers, ask for an example of how they handled a data-quality issue mid-test, and how they adapted. The best Amsterdam teams will show you a clear path from insight to shipped change to verified impact. No theatrics, just disciplined experimentation with real customer understanding. 💡
