Best Practices When Working With Duda
Based on patterns in our scan dataset and the detection evidence tiers.
- →Start by running a Duda detection scan on any URL you're evaluating — the 80+ signal engine returns a confidence score plus the exact markers it matched, which beats reading view-source by hand.
- →Cross-check the result against the full detection evidence in /how-scores-work — confidence tiers tell you whether a match is strong (headers + scripts) or circumstantial (a single HTML pattern).
- →Pair this page with the builder gallery (/gallery/duda) to see how Duda sites look in the wild and spot the design patterns that repeat across real deployments.
- →For migration planning, compare Duda against other builders in the same category — feature parity usually matters more than raw popularity.
