Keep critical content on the server
Use Server Components for primary structure and metadata. Isolate small controls instead of making a whole page client-rendered for one animation.
Treat metadata as route data
Give each indexable route a unique title, description and canonical. Use generated metadata for data-driven pages and make social fields match the record.
- One descriptive H1
- Self-referencing canonical
- Page-specific title and description
- Index directives for the environment
List only canonical URLs
A sitemap should contain URLs you want indexed, not utilities, parameters, redirects or placeholders.
Budget media and JavaScript
Reserve image dimensions, load below-fold media lazily and keep motion on transforms and opacity. Measure real templates rather than assuming a framework guarantees Core Web Vitals.
