TLDR: you don’t need paid tools. Use Nuxt's built-in SEO features, Google Lighthouse, Nuxt SEO module, and static pre-rendering to improve SEO without a monthly cost. If you need dynamic SEO fixes at runtime, consider Cloudflare Workers or Edge Functions.

Curious though why you want to mess with the code anyway? Most onpage issues are resolved with just getting an optimized title tag, Meta & H1.
