How to optimize SEO and performance for static sites

Static generation solves crawlability but doesn't guarantee a sound page structure. You still need to plan heading hierarchies, semantic tags, and internal links.

Keep one main heading per page. Ensure subheadings are sequential without skipping levels. Place critical content in the visible body text on the initial screen, not hidden behind interactions.

Performance: Compressing above-the-fold images to WebP with reserved dimensions, lazy-loading below-the-fold images, and on-demand code loading by route significantly reduces initial page size and layout shifts.

These are basic steps, but completing them will significantly stabilize your mobile experience and search engine indexing.
