About Lovable in SEOmatic

Every Lovable app is backed by a Supabase Postgres database. SEOmatic connects straight to it and writes rows into a table you choose, which your app renders like any other content. Nothing is added to your codebase.

Last Updated

Requirements

A Lovable app with Supabase connected, and a table for the pages to live in. You will need the Postgres connection string from Supabase > Project Settings > Database, and a route in your app that reads that table.

How to Fix Lovable SEO from Codex

Step 1: Connect Lovable to SEOmatic

SEOmatic writes into the Supabase database behind your Lovable app, so there is nothing to install and no code to change.

Step 1: In Supabase, open Project Settings, then Database, and copy the connection string.

Step 2: In SEOmatic, go to Connections, select Next.js (the Postgres database connector, which is what a Lovable app runs on), and paste it. SEOmatic validates the connection and confirms which database it reached.

Step 3: Choose the table your pages should live in and map its columns to title, content, slug and meta. SEOmatic matches the usual names for you.

Step 4: Agents research what your users search for and propose the pages to write. You approve what you want, and the rows land in your database ready for your app to render.

Step 2: Connect SEOmatic to Codex

Run these two commands in your terminal. The second one opens your browser: sign in to SEOmatic and pick your site. The CLI and the IDE extension share the same config, so this covers both.

Connect Codex

codex mcp add seomatic --url https://app.seomatic.ai/api/mcp
codex mcp login seomatic

Other ways to connect are on the Codex page.

Step 3: Ask Codex, Then Approve

Paste any of these. Codex answers from your data and stages the fix; you approve it before it reaches Lovable.

“Which of my Lovable pages lost the most clicks this month, and why?”
“Stage new titles for my Lovable pages with high impressions and low CTR.”
“Find Lovable pages Google has not indexed and tell me what is blocking them.”
“Audit my Lovable homepage and rank the fixes by impact.”

What Codex Can Change on Lovable

Writes The Pages

Full articles and landing pages from research to finished draft, published as rows your app renders.

Nothing Applies Without You

The agent arrives switched off and starts in approval mode. It earns more rope only when you give it.

No Code To Write

Agents talk to your database, not your repo. Nothing is added to your Lovable project and nothing can break your build.

Your Schema Is Untouched

Rows go into the table and columns you map. No tables created, no columns added, no migrations run.

Update, Never Duplicate

Agents remember the row they wrote and update it, so republishing does not leave you cleaning up copies.

Publish Verification

After publishing, SEOmatic fetches the live URL and tells you if your app is still serving the old version.

A Diff For Every Change

A before and after view with the reasoning attached, so you see what changed and why.

Draft And Published States

Rows carry their status, so your app can hold work back until you are ready for it to appear.

Works With Row Level Security

Connect with a role that can write to your content table. Your RLS policies stay exactly as you set them.

Lovable gets you a working app quickly, and then leaves you with the problem every founder hits next: nobody can find it. Agents handle that side, and stay on their own side of the line while doing it.

Frequently Asked Questions

What do I need to connect Lovable?

A Lovable app with Supabase connected, and a table for the pages to live in. You will need the Postgres connection string from Supabase Project Settings Database, and a route in your app that reads that table.

What do I need on the Codex side?

Codex (the CLI, the IDE extension or the desktop app) signed in with your ChatGPT account, and a free SEOmatic account. No API key needed for the browser sign-in.

Will Codex publish to Lovable without asking?

No. By default every change SEOmatic proposes waits for your approval before it touches your site, and your assistant is told never to approve on its own. Approved changes are stored with the page's previous state, so any edit to an existing page can be rolled back. If you later want low-risk fixes to go ahead on their own, you can turn that on in your autonomy settings; changes to your URLs or indexing, and new content, still wait for you.

Is it free?

Connecting is free with no card: 5 questions a month from your own data, plus 10 once you connect Search Console, and site audits of up to 30 pages. Staging and publishing fixes is part of paid plans, which start with a 14-day free trial.
