Frequently Asked Questions
Everything you need to know about the product and billing.
Is Astro SEO Theme really free?
Yes! It is 100% open-source and released under the MIT license. You can use it for personal and commercial projects without any attribution required (though it is always appreciated!).
Do I need to know React to use this?
Not at all. The entire core is built with Astro and standard HTML/CSS. React is only used for highly interactive components (like the Pricing toggle and Dark Mode switch) using Astro Islands, meaning 0kb of JS is loaded for the rest of the site.
How is the JSON-LD generated?
We have built custom Astro components that automatically read your content (like the Blog frontmatter or the FAQs array) and generate valid Schema.org JSON-LD scripts in the `<head>` of the document. This helps Google understand your content structure instantly.
Can I host this on Vercel or Netlify?
Absolutely. Astro compiles to static HTML/CSS (SSG) by default, meaning you can deploy it to any static host like Vercel, Netlify, Cloudflare Pages, or even GitHub Pages with zero configuration.
