How to make ChatGPT read your site built with v0
v0 generates Next.js projects, which can serve already-painted HTML out of the box. The problem shows up when the important content lives in client components that load it later.
Depends on how it was built or on a setting.
Why it happens
In Next.js, server components arrive with their text inside the HTML. Components marked "use client" are also rendered on the server the first time, except whatever they load with effects or browser requests.
If your prices, copy or product pages are fetched from the browser, the AI crawler receives the skeleton without the data.
So a v0 site can be almost perfect or almost empty for AI, depending on how each page was built.
How to fix it
Analyze the live site
Tarsier compares what a person sees with what a crawler receives and points out which blocks get lost.
Load data on the server
Move data requests out of client effects into server components or the page's data loading.
Metadata with the Next API
Use generateMetadata for each page's title and description, and add JSON-LD to the home page.
robots.txt and sitemap
Next has app/robots.ts and app/sitemap.ts: let AI bots in and list every route.
The prompt to paste into v0
My site is a Next.js project generated with v0. I want all public content to arrive already rendered in the HTML for AI crawlers, which don't run JavaScript. 1. Review the public pages and move into server components any data loading that currently happens in the browser (useEffect, SWR, fetch inside "use client" components) for copy, prices, products or FAQs. 2. Keep only interactive parts on the client (cart, filters, forms). 3. Add generateMetadata with its own title and description on every page, and schema.org JSON-LD on the home page. 4. Create app/robots.ts allowing GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot and Google-Extended, and app/sitemap.ts with every public route. Don't change the design. When you're done, tell me which pages loaded data on the client and what you moved.
Copy it as is. If the analysis finds more problems, the full report includes a prompt written for your site.
Frequently asked questions
Doesn't Next.js already render on the server?
Yes, but only what it has at render time. Whatever is requested from the browser afterwards arrives too late for a crawler that doesn't run JavaScript.
Do I have to host it on Vercel?
Not necessarily, but it does need a host that runs Next.js with its server. If you export it as static, check that pages come out with their content.
