Technical SEO Audit Checklist for React + Vite Sites (SPA-Friendly)
Single-page apps can rank, but you need technical discipline: clean canonicals, correct routing, fast performance, and consistent metadata. This checklist focuses on what search engines and social scrapers actually need.
We can quickly review your setup and show you what’s working and what needs improvement.
1) Crawlability and index control
- robots.txt present and allows core pages
- sitemap.xml generated and up to date
- noindex applied to non-search pages (thank-you, 404)
If you want help implementing this end-to-end, see SEO Services.
2) Canonicals and duplicate control
- Each route outputs a canonical URL
- No query strings or hash fragments in canonicals
- HTTP → HTTPS consistency
3) Metadata for social sharing
- Absolute OG/Twitter image URLs
- Per-page OG titles/descriptions
4) Structured data
- BreadcrumbList on key pages
- Service schema on service pages
- FAQPage on posts where FAQs exist
FAQ
Do SPAs need server-side rendering for SEO?
Not always. Many sites succeed with client-side rendering when metadata, crawl paths, and performance are handled well. SSR can help some bots, but it’s not always required.
What’s the #1 SEO risk in SPAs?
Inconsistent metadata (missing canonicals/OG tags) and thin crawl paths. A strong internal linking structure helps.
What should we focus on first?
Canonicals + sitemap/robots + performance. Then expand content and internal links.
