In Umbraco, Document Types define the structure of your content.
A common mistake is creating overly generic page types that try to handle everything. This makes content harder to manage and creates inconsistent editing experiences.
Well-designed Document Types make content editing clearer, reduce mistakes, and help developers maintain cleaner templates and stronger validation.
They also make permissions and publishing workflows easier to control.
Tip: If editors need instructions to know what belongs in a field, the Document Type probably needs improvement.
