The template ceiling
Template websites carry code for thousands of features you'll never use — which means slow loading, poor Core Web Vitals and Google rankings that plateau. They also look like everyone else, which quietly erodes trust with premium customers.
Performance is revenue
Every second of load time measurably reduces conversions. Custom-built sites ship only the code they need, hit 90+ Lighthouse scores, and get rewarded by Google's page-experience signals.
SEO advantages of custom builds
Clean semantic HTML, per-page structured data, precise meta control and fast rendering are trivial in a custom build and painful in a template. That technical edge compounds into rankings over time.
The modern economics
AI-accelerated development has collapsed the cost gap. At Merveille Nexus, a fully custom, SEO-engineered website often costs comparable to a heavily customized template project — while performing in a different league.
