What v0's own documentation says about how AI crawlers see sites built with it, and the exact settings for robots.txt, llms.txt, structured data and the sitemap.

## How v0 delivers pages to crawlers

**Server-rendered HTML by default (Next.js)** (HTML without JavaScript (documented))

v0's docs say new chats start with a Next.js app and that v0 uses React Server Components "for improved performance and SEO". Next.js docs say pages and layouts are Server Components by default, and that Client Components are also pre-rendered to HTML on the server. The exception is content you deliberately load only in the browser, for example with `next/dynamic` and `ssr: false`. v0 can use other frameworks, but says Next.js gives the most reliable results.

Why it matters: many AI crawlers don't run JavaScript. If your text only appears after scripts run, they may see an empty page.

## What we found on 7 v0 sites we track

Average AI visibility score 75/100 · 29% only show page text after JavaScript runs · 43% have no llms.txt (crawl up to 2026-10-18).

## Make your content readable without JavaScript

1. Keep v0 on its default Next.js setup.
2. Keep text you want quoted in Server Components or in the initial render. Don't wrap important content in a component loaded with `ssr: false`.
3. Publish, then view the page source of the live URL (or run the [free audit](https://getrankroot.com/#scan)) and search for your headline text.

## robots.txt: let AI search crawlers in

1. Ask v0 to add an `app/robots.ts` file (the Next.js robots file convention) or a static `public/robots.txt`.
2. Publish and open `yourdomain.com/robots.txt` to confirm.

app/robots.ts that lets AI search crawlers in:

```
import type { MetadataRoute } from "next";

export default function robots(): MetadataRoute.Robots {
  return {
    rules: [
      { userAgent: ["OAI-SearchBot", "ChatGPT-User", "PerplexityBot", "Claude-SearchBot", "Claude-User"], allow: "/" },
      { userAgent: "*", allow: "/" },
    ],
    sitemap: "https://yourdomain.com/sitemap.xml",
  };
}
```

## Add llms.txt

1. Next.js serves files in the `public` folder from the root URL, so `public/llms.txt` is served at `/llms.txt`.
2. Write the file with the [llms.txt generator](https://getrankroot.com/tools/llms-txt-generator) and ask v0 to add it to `public/`.
3. Publish, open `yourdomain.com/llms.txt`, and check it with the [llms.txt validator](https://getrankroot.com/tools/llms-txt-validator).

## Add JSON-LD and head code

1. Ask v0 to export `metadata` (or `generateMetadata`) from each page with a unique title and description. This is Next.js's Metadata API.
2. For JSON-LD, Next.js recommends rendering a `<script type="application/ld+json">` tag in your `layout` or `page` component, and replacing `<` with `\u003c` in the JSON to prevent script injection.

JSON-LD in a Next.js page (Next.js docs pattern):

```
const jsonLd = { "@context": "https://schema.org", "@type": "Organization", name: "Your company", url: "https://yourdomain.com" };

<script
  type="application/ld+json"
  dangerouslySetInnerHTML={{ __html: JSON.stringify(jsonLd).replace(/</g, "\\u003c") }}
/>
```

## Sitemap

1. Ask v0 to add an `app/sitemap.ts` file (the Next.js sitemap file convention) that lists every public URL on your custom domain.
2. Reference it from `robots.ts` with the `sitemap` field.
3. Publish and open `yourdomain.com/sitemap.xml`.

## Common mistakes

- Loading key content with `next/dynamic` and `ssr: false`. Next.js says this disables pre-rendering, so the content isn't in the HTML crawlers receive.
- Injecting JSON-LD with a client-side script after the page loads instead of rendering it in the page, as Next.js recommends.
- Asking v0 to switch to another framework without checking how that framework renders. v0 says Next.js gives the most reliable results.

## FAQ

### Is my v0 site visible to ChatGPT?

v0 builds Next.js apps by default, and Next.js renders pages to HTML on the server, so crawlers usually get your content. Your robots.txt must allow AI crawlers, and content loaded only in the browser won't be in the HTML. Run the free audit on your live URL to confirm.

### Does v0 add robots.txt and a sitemap automatically?

v0's docs don't say so. Ask v0 to add app/robots.ts and app/sitemap.ts, which are the standard Next.js file conventions.

### How do I add llms.txt to a v0 project?

Put the file at public/llms.txt. Next.js serves the public folder from the root, so it appears at /llms.txt after you publish.
