Free SvelteKit SEO Audit
SvelteKit's server-side rendering gives you a strong SEO base — but missing <svelte:head> metadata on routes, no built-in sitemap endpoint, and prerender gaps are the issues a generic audit won't surface. DeepSEOAnalysis audits SvelteKit sites with framework-specific context.
WHAT WE CHECK
6 SvelteKit-specific SEO checks
Beyond the 80+ general checks, the engine applies SvelteKit-aware analysis when it detects a SvelteKit site — covering metadata, data loading strategy, sitemap, and rendering configuration.
<svelte:head> metadata coverage
SvelteKit sets page metadata inside `<svelte:head>` blocks in each `+page.svelte` file: `<title>`, `<meta name="description">`, Open Graph tags, and canonical links. Pages without their own `<svelte:head>` inherit only the root layout's head content — producing the same generic title and description across all routes that don't override it. The audit checks every crawled page for unique, present title tags and meta descriptions, flagging pages that share the root layout's default metadata.
load function and SSR content
SvelteKit's `load` function in `+page.server.js` (or `+page.js`) runs before the page is rendered and passes data to the component. Server-side `load` functions run on every request (SSR) or at build time (prerender), embedding all content in the initial HTML. Client-side `load` functions (in `+page.js` without `+page.server.js`) can run in the browser after hydration — content loaded client-side only is invisible to Googlebot on the first fetch. The audit flags pages where primary content (H1, body text) is absent from the initial server response.
Sitemap endpoint
SvelteKit has no built-in sitemap generator. A sitemap must be implemented as a `+server.js` route at `src/routes/sitemap.xml/+server.js` that returns XML from a `GET` handler. Without a sitemap, Googlebot relies entirely on internal link crawling to discover pages — missing pages with few inbound links. The audit checks whether the site has a sitemap, whether it's referenced in robots.txt, and whether all crawled pages appear in the sitemap XML.
robots.txt and AI crawler access
SvelteKit serves static files from the `static/` directory at the root URL. Placing a `static/robots.txt` file is the simplest way to serve robots.txt. Alternatively, a `+server.js` route at `src/routes/robots.txt/+server.js` generates it dynamically. A common gap: no robots.txt file exists, or the file exists but has no `Sitemap:` directive. Equally important: check that AI crawlers (GPTBot, ClaudeBot, PerplexityBot) are allowed — blocking them reduces AI visibility without any SEO benefit.
Prerender configuration
SvelteKit supports page-level prerendering with `export const prerender = true` in `+page.js`. Prerendered pages are built to static HTML at build time — faster, CDN-cacheable, and crawlable immediately with no server load. Pages that could be prerendered (blog posts, static landing pages, glossary terms) but aren't fall back to SSR (a server request per crawl). The audit identifies key content pages that are SSR-rendered and could benefit from `prerender = true` for better crawl performance and Core Web Vitals.
AI visibility for SvelteKit apps
SvelteKit makes AI visibility tasks clean: `llms.txt` goes in `static/llms.txt` (auto-served at `/llms.txt`), FAQPage JSON-LD is added via `<svelte:head>` with a `<script type="application/ld+json">` tag in the `+page.svelte` component, and Open Graph metadata per page is set in the same `<svelte:head>` block. The audit checks all five AI visibility signals — llms.txt presence, AI crawler access, FAQPage/HowTo schema, question-heading ratio, and content chunkability — with the specific SvelteKit pattern for each fix.
HOW IT WORKS
Audit your SvelteKit site in 60 seconds
- Enter your deployed SvelteKit URL. Works with Vercel, Netlify, Cloudflare Pages, Fly.io, or self-hosted Node.js. No source code access needed — the audit crawls the live site.
- We crawl and analyse. The engine crawls up to 50 pages (free) or 1,000 pages (paid), checks metadata coverage across all routes, validates JSON-LD schema, measures CrUX Core Web Vitals from real user data, and evaluates all five AI visibility signals.
- You get a prioritised report. Framework-aware issues first — missing svelte:head metadata, absent sitemap endpoint, prerender opportunities — then general SEO, each with the exact SvelteKit file and pattern to fix it.
FAQ
Questions about the SvelteKit SEO audit
Does DeepSEOAnalysis detect SvelteKit-specific SEO issues?
Yes. The engine detects SvelteKit signals — server-rendered HTML from SvelteKit's `load` functions, `<svelte:head>` metadata patterns, and prerender configuration — and surfaces framework-specific guidance alongside the 80+ general checks.
Is SvelteKit good for SEO?
SvelteKit's default SSR mode is excellent for SEO: the `load` function runs server-side, and content is embedded in the initial HTML response before any JavaScript runs. The common SvelteKit SEO gaps are in the details: pages missing `<svelte:head>` metadata fall back to the root layout's head content; there's no built-in sitemap generator (requires a `+server.js` endpoint); and pages set to `export const prerender = false` that could be prerendered miss the CDN caching benefit.
How does the audit handle SvelteKit's rendering?
SvelteKit renders pages server-side by default (SSR mode) or as static HTML at build time (prerender mode). The audit fetches pages directly and checks whether the H1, body content, and metadata are in the initial server response — no JavaScript execution required. Pages using SvelteKit's client-only rendering patterns (hooks that render after hydration) are flagged if their primary content is missing from the server HTML.
Is the SvelteKit SEO audit free?
Yes. The complete audit is free with no signup and no email gate. Paid plans add saved history, scheduled monitoring, larger crawls (up to 1,000 pages), and agency workflows.
