Best Use Case
Best for those prioritising speed and simplicity with SEO needs.
Key SEO Considerations
Svelte is a compiler that shifts work to the build step, resulting in highly optimized vanilla JavaScript with minimal runtime overhead.
This leads to exceptionally fast performance and small bundle sizes, which are major advantages for SEO.
SvelteKit is the official full-stack framework for Svelte, providing SSR and other features necessary for robust SEO out of the box.
The svelte:head element provides a simple, native way to manage head metadata.
The Disappearing Framework
Compiled, Not Runtime
Svelte is not a runtime library; it's a compiler. It converts your components into highly efficient vanilla JavaScript at build time. There is no Virtual DOM. This results in significantly smaller bundle sizes and faster performance. SvelteKit is the official application framework that provides SSR, routing, and a full-stack structure for Svelte.
Performance Advantage
Built for Speed
The primary SEO advantage is exceptional performance. SvelteKit employs SSR by default, ensuring crawlers receive fully-rendered HTML. The compiler approach leads to minimal bundle sizes, which directly contributes to faster page loads and better Core Web Vitals scores.
Simple SEO Implementation
Native and Elegant
SvelteKit provides simple, built-in mechanisms for SEO.
<svelte:head>: A special, native Svelte element that allows you to insert tags directly into the document's head. It's simple, requires no external libraries, and works seamlessly with SSR.- Load Functions: Data for a page is fetched in
loadfunctions, which run on the server, making the data available for SSR and for populating the<svelte:head>element. - Sitemaps: A
sitemap.xmlcan be easily generated by creating a dynamic server endpoint.
Actionable Recommendations
- Trust the defaults: rely on SvelteKit's default SSR for its performance benefits.
- Use
<svelte:head>for all page-specific metadata. - Fetch all data needed for a page's content and metadata within its
loadfunction. - Create a sitemap endpoint to dynamically generate a sitemap for your application.
