About Blogger in SEOmatic

SEOmatic connects to Blogger through Google's own Blogger API, authorized with your Google account. Agents write new posts and pages, refresh the ones you already published, and manage drafts, on blogspot.com addresses and custom domains alike.

Requirements

A Blogger blog, on a blogspot.com address or a custom domain, owned by the Google account you connect with. No API key, no plugin, nothing to install.

How to Fix Blogger SEO from Codex

Step 1: Connect Blogger to SEOmatic

Blogger is the rare platform where connecting really is one click, because the authorization is Google's own.

Step 1: In SEOmatic, go to Connections, select Blogger, and click Connect with Google.

Step 2: Sign in with the Google account that owns your blog and approve access. SEOmatic picks the blog that matches your workspace's site automatically. There is no collection or content type to choose.

Step 3: Agents read your Search Console data, find what is holding your posts back, and propose the fixes with the reasoning attached.

Step 4: You approve what you want. Approved work is written to your blog, 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.

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 Blogger.

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

What Codex Can Change on Blogger

Writes And Refreshes Posts

Full articles from research to finished draft, plus rewrites and content refreshes on posts and pages already published.

Body-Level Fixes That Land Live

Internal links, FAQ blocks, heading fixes, broken-link repairs and freshness updates are all edits to the post body, so they apply directly.

Drafts And Labels

New posts can arrive as drafts for you to publish, labels are set on the way in, and publishing a draft later is one click.

Honest About The Ceiling

Blogger's API exposes no meta description, canonical, robots or schema fields, for anyone. Agents never pretend otherwise: work that needs those arrives as a prepared change for you to apply in Blogger's own settings, and is never claimed as applied.

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

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

One Click Revert

Any change rolls back to its exact previous value. Low-risk edits that cost you traffic revert on their own.

Your URLs Are Never Touched

Blogger derives post URLs from titles at publish time and the API cannot change them afterwards, so an agent edit can never move or break an existing URL.

Blogger gives you free hosting on Google's infrastructure and then leaves you alone. Nothing tells you which posts are slipping, rewrites them, or links them together. That is the part agents take over, and they are upfront about the parts Blogger's API keeps off limits for everyone.

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 Blogger 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.
