Lovable and AI search: what crawlers meet, and what to change

New Lovable apps render on the server; older ones are pre-rendered only for crawlers Lovable verifies. Which kind an app is decides what everyone else sees.

What AI crawlers meet on Lovable

Lovable creates a robots.txt with every project that allows Googlebot, Bingbot, the social preview bots and everyone else, so AI crawlers may read the app. What decides whether they read anything is rendering. Apps created since 13 May 2026 run on TanStack Start and render on the server: every request gets the page. Older React and Vite apps are pre-rendered on request, but only for the crawlers Lovable verifies — Google, Bing, the ChatGPT, Claude, Perplexity and Gemini crawlers, social bots — so anything else, from SEO tools to Passcite's own Site health, gets the empty page below. Lovable can move an older app to TanStack Start from the chat.

The changes a report asks for on the site itself, and llms.txt, which it does not.

    Possible: Yes
    Who: You, with steps
    Where: Lovable writes a title and description for each page as it builds; change them through the chat. On TanStack apps each route carries its own.

  • New pages (FAQ, comparison, use case)

    Who: We write; whoever runs the site puts it up
    Where: The normal page editor.

  • A new section on an existing page

    Possible: Yes
    Who: We write; whoever runs the site puts it up
    Where: The page it goes on, in the normal editor, beside the section it follows.
Checklist

Getting a Lovable site ready to be cited

  1. 01

    Find out which kind of app it is

    Created since 13 May 2026, it renders on the server. Older, it is a Vite app pre-rendered for verified crawlers only.

  2. 02

    Move an older app to TanStack Start

    Ask the chat to 'Migrate to TanStack Start'. It costs credits, and the live site does not change until you publish.

  3. 03

    Check an older app with Google, not curl

    curl and most tools get the empty page. Search Console's URL Inspection shows what Googlebot received.

  4. 04

    Run the SEO & AI review

    More → Analytics → SEO & AI checks the sitemap, robots.txt, metadata, structured data and AI readiness, and connects Search Console.

  5. 05

    Add a sitemap if there is none

    Lovable does not always create /sitemap.xml.

Check it yourself

Free, no account. Each reads what your site serves today, the way the crawlers do.

Publishing

Why we don’t publish to Lovable

You would not want it: you can make every change in the editor faster than you could review a diff. The report is the part worth buying. An approved page comes as Markdown or HTML to commit; once it is deployed and you give us its address, we look for it on the site.

FAQ

Questions

Can AI crawlers read a Lovable app?
Yes, for apps created since May 2026, which render on the server. Older apps are pre-rendered for the crawlers Lovable verifies, the ChatGPT, Claude, Perplexity and Gemini ones among them; other clients get an empty page.
Why does Passcite say my Lovable page is empty?
On an older Vite app, Passcite reads what an unverified crawler gets: the empty page. Google and the AI crawlers Lovable verifies get a pre-rendered page. Moving the app to TanStack Start gives every client the same page.
Does Lovable write an llms.txt?
No. A file you add at public/llms.txt is served from the root.
Do I need to give Passcite access to my Lovable site?
No. The report reads public pages, the same as any visitor, and nothing we do connects to your Lovable account.
What does Passcite cost?
The first report is free on a free account: one brand, 10 prompts, three engines, no card. Plans start at $49 a month for 150 credits — a prompt asked on three engines is one, an article 10.
