About Next.js in SEOmatic
SEOmatic publishes into the Postgres database behind your Next.js site. You pick the table and map your columns, and SEOmatic writes the rows your existing routes render.

Requirements
A Postgres database reachable from the public internet, with a table that has an id column, plus INSERT and UPDATE permissions. Works with Supabase, Neon, Railway, Render, RDS and Lightsail. SSL is used automatically.
How to Fix Next.js SEO from Claude Code
Step 1: Connect Next.js to SEOmatic
SEOmatic writes directly into the Postgres database your Next.js site already reads from. Works with both App Router and Pages Router, because SEOmatic never touches your routing.
Step 1: In SEOmatic, go to Connections and select Next.js.
Step 2: Paste your Postgres connection string. SEOmatic validates it and confirms the database name.
Step 3: Pick the table to publish into, then map its columns to title, content, slug, excerpt, image and meta fields.
Step 4: Build your content template using variables, AI, or both, and publish. SEOmatic inserts new rows and updates ones it published before, so republishing never creates duplicates.
Because your pages are rendered by your own code, revalidate the route after publishing (revalidatePath) or render it dynamically, so new content is visible to search engines right away.
Step 2: Connect SEOmatic to Claude Code
Run this in your terminal. Then start Claude Code, type /mcp, pick seomatic and choose Authenticate. Sign in to SEOmatic in the browser and pick your site.
claude mcp add --transport http seomatic https://app.seomatic.ai/api/mcpOther ways to connect are on the Claude Code page.
Step 3: Ask Claude Code, Then Approve
Paste any of these. Claude Code answers from your data and stages the fix; you approve it before it reaches Next.js.
- “Which of my Next.js pages lost the most clicks this month, and why?”
- “Stage new titles for my Next.js pages with high impressions and low CTR.”
- “Find Next.js pages Google has not indexed and tell me what is blocking them.”
- “Audit my Next.js homepage and rank the fixes by impact.”
What Claude Code Can Change on Next.js
Full articles and programmatic pages from research to finished draft, published as rows your routes already render.
The agent arrives switched off and starts in approval mode. It earns more rope only when you give it.
Agents remember the row they wrote and update it, so republishing does not leave you cleaning up copies.
Map your table's columns once to title, content, slug, excerpt, image and meta. Common names are matched for you.
After publishing, SEOmatic fetches the live URL and tells you if your route is still serving the old version.
Rows carry their status, so your app can hold work back until you are ready for it to appear.
App Router or Pages Router makes no difference, because agents never touch your routing layer.
Supabase, Neon, Railway, Render, RDS or Lightsail. SSL is used automatically and nothing is added to your schema.
Whole page sets generated from your data and real search demand, with sample pages shown before any of it lands.
Your app owns the rendering, so agents stay on their side of the line: they research, write and publish rows, and your code decides what happens to them.

Frequently Asked Questions
Can Claude Code fix SEO on my Next.js site?
Yes, through SEOmatic. Claude Code reads your Google Search Console data, finds what is holding your Next.js pages back and stages the fix. SEOmatic publishes into the Postgres database behind your Next.js site. You pick the table and map your columns, and SEOmatic writes the rows your existing routes render.
What can Claude Code change on Next.js?
Writes The Pages: Full articles and programmatic pages from research to finished draft, published as rows your routes already render. Nothing Applies Without You: The agent arrives switched off and starts in approval mode. It earns more rope only when you give it. Update, Never Duplicate: Agents remember the row they wrote and update it, so republishing does not leave you cleaning up copies. Column Field Mapping: Map your table's columns once to title, content, slug, excerpt, image and meta. Common names are matched for you. Publish Verification: After publishing, SEOmatic fetches the live URL and tells you if your route is still serving the old version. Draft And Published States: Rows carry their status, so your app can hold work back until you are ready for it to appear.
What do I need to connect Next.js?
A Postgres database reachable from the public internet, with a table that has an id column, plus INSERT and UPDATE permissions. Works with Supabase, Neon, Railway, Render, RDS and Lightsail. SSL is used automatically.
What do I need on the Claude Code side?
Claude Code and a free SEOmatic account. No API key and no Google Cloud project: the connection signs in through your browser.
Will Claude Code publish to Next.js 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.
