Lovable SEO: why Google can't see your app (and how to fix it)
Why Google sees an empty page, and the fixes that work
You built something great in Lovable, published it, and waited for Google. Weeks later, it barely shows up. The design is fine, the copy is fine. The problem is what search engines actually receive when they visit.
Why Lovable apps can look empty to Google
Lovable builds apps with React and Vite. That's a fast, modern setup, but by default it renders everything in the browser. When someone opens your page, the server sends a nearly empty HTML file with one line that matters:
<div id="root"></div>
Then JavaScript downloads, runs, and draws your whole page inside that box. For a person with a modern browser, it all happens in a second or two. For everything else, that empty box is what they get:
- Google can run JavaScript, but it does it in a second, slower pass. Pages can wait days to be rendered, and some never are.
- AI search tools (ChatGPT search, Perplexity and others) mostly read the raw HTML. An empty page gives them nothing to quote.
- Link previews on LinkedIn, WhatsApp, Slack and X never run JavaScript. They only see what's in the HTML head.
So the content you wrote is there for visitors, but invisible to the systems that send you visitors.
How to check your own app
You don't need to read code. Open the free vibe code audit, paste your app's address, and look at the first SEO check.
- Paste your published address (your own domain or the .lovable.app one).
- The audit loads the page the way Google first sees it, before any JavaScript.
- If it reports an empty page, you'll see how many words were actually in the HTML. For most Lovable apps, that number is zero.
- Read the other SEO checks too: default titles, a missing share image, and a share tag that still credits @Lovable are all common.
The quick wins (minutes, no code)
These don't fix the empty page, but they fix what search engines and link previews read first, and they're easy to get wrong.
- A real title. Ask Lovable to "set a unique title for every page, about 55 characters, with the main keyword first". Default titles like "Lovable App" or "Vite + React" are still everywhere.
- A real meta description. One or two sentences, 120 to 160 characters, saying who it's for and what they get.
- Your own share image. A 1200x630 image in the og:image tag. Check it with the link preview checker before you post the link anywhere.
- Your own X handle. Replace the default twitter:site tag, or remove it.
- robots.txt and a sitemap. Ask Lovable to add both, with the sitemap listing every public page.
- A custom domain. Everything you earn in search builds up on the domain. Make it yours, not a subdomain.
The real fix: send real HTML
To solve the empty page, your public pages need to arrive with their content already in the HTML. There are three ways, from easiest to most robust.
1. A prerendering service
A prerendering service sits in front of your site. When a search engine or link preview bot visits, it serves a fully rendered copy of the page. People still get the normal app. It's the least work, but it adds a service and a monthly cost, and you need hosting that lets you add it.
2. Prerender at build time
Connect your Lovable project to GitHub, deploy it on a host like Vercel or Netlify, and add a prerendering step to the build. It saves a full HTML copy of each public page when you deploy. This works well for pages that don't change per user: your homepage, pricing, features and blog.
3. Split marketing pages from the app
The most robust setup keeps the logged-in app in Lovable, and moves the public pages (homepage, pricing, blog) to a framework that renders on the server, like Next.js or Astro. Search engines get complete pages, and the app stays exactly as it is. It's more work, so it makes sense once search becomes a real channel for you.
What about speed?
Lovable apps often ship a lot of JavaScript in one file, and a phone has to download and run all of it before anything shows. That hurts Core Web Vitals, which feed into rankings. The audit shows how much your app loads up front. Under 500 KB is comfortable. Over 1 MB is worth fixing by loading pages and heavy parts (charts, editors, maps) only when they're needed. Run a speed audit for the full picture.
Frequently asked questions
Is Lovable bad for SEO?
No, but its default setup renders pages in the browser, which makes search engines work harder to see your content. With good titles, descriptions, a sitemap and prerendering for public pages, a Lovable app can rank well.
Does Google index Lovable apps?
Yes, Google can render JavaScript and index them, but it's slower and less reliable than plain HTML. Many AI search tools and all link previews don't run JavaScript at all, so they see an empty page.
How do I check what Google sees on my app?
Run the free mktbox vibe code audit on your address. It loads the page without JavaScript, the way search engines see it first, and tells you how many words are actually there.
Do I need to leave Lovable to fix SEO?
No. The quick wins happen inside Lovable, and prerendering can be added by deploying the same code to your own host. Only the most robust option moves your public pages to a separate framework.
