About HubSpot CMS in SEOmatic
SEOmatic connects to HubSpot in one click. Agents write new blog posts, rewrite the ones you already published, and fix the SEO settings of your landing and site pages. Nothing is written until you approve it.

Requirements
A HubSpot account with Content Hub (formerly CMS Hub) and permission to approve apps for it. Connecting happens on HubSpot's own consent page; an existing private app with the content scope also works.
How to Fix HubSpot CMS SEO from Codex
Step 1: Connect HubSpot CMS to SEOmatic
SEOmatic connects to your HubSpot account in one click, then works on the posts and pages you already have.
Step 1: In SEOmatic, go to Connections, select HubSpot and click Connect with HubSpot.
Step 2: Approve access on HubSpot's own consent page. SEOmatic loads your blogs and selects one for you if you only have one. (Already have a private app with the content scope? You can paste its token instead. HubSpot is switching off the creation of new legacy private apps.)
Step 3: Agents read your Search Console data, find the posts and pages losing clicks they should be winning, and propose the fixes with the reasoning attached.
Step 4: You approve what you want. Approved work is written to HubSpot, logged as a diff you can read, and undone in one click if you change your mind.
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.
codex mcp add seomatic --url https://app.seomatic.ai/api/mcp
codex mcp login seomaticOther 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 HubSpot CMS.
- “Which of my HubSpot CMS pages lost the most clicks this month, and why?”
- “Stage new titles for my HubSpot CMS pages with high impressions and low CTR.”
- “Find HubSpot CMS pages Google has not indexed and tell me what is blocking them.”
- “Audit my HubSpot CMS homepage and rank the fixes by impact.”
What Codex Can Change on HubSpot CMS
Full blog posts with titles, HTML content, excerpts, featured images, tags and author, plus rewrites of what is already live.
On a landing or site page with unpublished edits from your team, the agent leaves the page alone rather than publishing their draft along with its change.
The agent arrives switched off and starts in approval mode. It earns more rope only when you give it.
SEOmatic reads the real post back from HubSpot, so the before and after you approve is the live content, not a guess.
Any change rolls back to its previous value. Low-risk edits that cost you traffic revert on their own.
Every change is read back from HubSpot before it counts as applied. If pushing a page live fails, its draft is reset so nothing is left half done.
Posts are filed against your existing HubSpot tags and blog authors, so author signals stay intact.
HubSpot takes standard HTML, so content goes across as written rather than through a lossy format conversion.
If your portal runs several blogs, pick the one to work in. With only one, SEOmatic selects it for you.
Agents work through HubSpot's own content API, and nothing is written until you approve it. Approved edits to a blog post update the live post directly; on landing and site pages the change goes through the page's draft and is pushed live, and a page with unpublished edits from your team is left alone.

Frequently Asked Questions
Can Codex fix SEO on my HubSpot CMS site?
Yes, through SEOmatic. Codex reads your Google Search Console data, finds what is holding your HubSpot CMS pages back and stages the fix. SEOmatic connects to HubSpot in one click. Agents write new blog posts, rewrite the ones you already published, and fix the SEO settings of your landing and site pages. Nothing is written until you approve it.
What can Codex change on HubSpot CMS?
Writes And Rewrites Posts: Full blog posts with titles, HTML content, excerpts, featured images, tags and author, plus rewrites of what is already live. Your Team's Drafts Stay Theirs: On a landing or site page with unpublished edits from your team, the agent leaves the page alone rather than publishing their draft along with its change. Nothing Applies Without You: The agent arrives switched off and starts in approval mode. It earns more rope only when you give it. A Diff For Every Change: SEOmatic reads the real post back from HubSpot, so the before and after you approve is the live content, not a guess. One Click Revert: Any change rolls back to its previous value. Low-risk edits that cost you traffic revert on their own. Never A False Success: Every change is read back from HubSpot before it counts as applied. If pushing a page live fails, its draft is reset so nothing is left half done.
What do I need to connect HubSpot CMS?
A HubSpot account with Content Hub (formerly CMS Hub) and permission to approve apps for it. Connecting happens on HubSpot's own consent page; an existing private app with the content scope also works.
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 HubSpot CMS 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.
