How to Fix GitHub SEO from Hermes Agent
Why Hermes Agent Needs SEOmatic on GitHub
Hermes Agent is built for work that runs without you watching, so it suits a recurring check on your GitHub site: compare your HTML pages and Markdown posts against Search Console every week, speak up only when something moved, and stage the fix. In Approval mode nothing reaches GitHub until you approve it, and SEOmatic writes it through pull requests on your repository.
What It Looks Like
You: Every Monday, check my GitHub site and flag pages that lose clicks.
Hermes Agent: This week's check: from Sep 13 to Oct 10 (28 days), /blog/drain-cleaning-cost had 2,640 impressions and 21 clicks at position 8.7 for "drain cleaning cost". That is a low click rate for page one, so the title is the first thing to test: it reads "Drain Cleaning". I staged a new title, "Drain Cleaning Cost: What You Will Pay", to be written to the title in the post's front matter, opened as a pull request. Approve it and SEOmatic opens the pull request; it goes live when you merge.
An example on a demo site; your numbers come from your own Search Console.
Step 1: Connect GitHub to SEOmatic
In SEOmatic, go to Connections, select GitHub, and click Continue with GitHub. On GitHub, install the app on the one repository your site lives in. GitHub sends you back to SEOmatic. The full walkthrough, with every screen, is on the GitHub integration page.
Step 2: Connect SEOmatic to Hermes Agent
Run this in your terminal. Hermes registers the server, opens your browser to sign in to SEOmatic, and stores the token. Answer Y when it asks to enable all tools. Then run hermes mcp test seomatic.
Connect Hermes Agent
hermes mcp add seomatic --url https://app.seomatic.ai/api/mcp --auth oauthOther ways to connect are on the Hermes Agent page.
Step 3: Ask Hermes Agent, Then Approve
Paste any of these into Hermes Agent. It answers from your data and stages the fix; you approve it before it reaches GitHub.
- “Audit my live site and point me to the files behind each issue.”
- “Open a pull request with better titles for my Markdown posts with low CTR.”
- “Which posts rank 5 to 15 and could move up with a refresh?”
More that work well in Hermes Agent:
- “Every Friday, send me what changed on Google”
- “Which pages lost clicks this month?”
- “Is /drain-cleaning-cost indexed?”
Did It Work?
After you approve, SEOmatic writes the change through pull requests on your repository and checks that it is live. Then it measures the result against the page's own baseline and your site's trend: 14 days after a title change, 28 after a content refresh, 90 after a new page. Each change is marked verified, ineffective or regressed, and a low-risk change that loses traffic is rolled back on its own. Ask Hermes Agent "Did my GitHub title changes work?" and it answers from those verdicts.
What Hermes Agent Can Change on GitHub
HTML Pages, Fully
On plain HTML files, agents set the title, meta description, canonical tag and structured data, and rewrite content inside your page's existing main element. Structured data sits in a clearly marked block, so your own markup is never touched.
Markdown and MDX Front Matter
On Markdown and MDX files, agents update the title and description in the front matter. The body is left alone, because converting it through HTML and back breaks its formatting and can break an MDX build, and a lossy edit is worse than none.
New Blog Posts in Batches
On a Markdown blog, programmatic pages arrive as one pull request per batch, all in a single commit with a manifest. The next batch is queued only once you merge the last one, and undoing a batch is reverting one commit.
A repository has no fields and no API for SEO, only files. So the agent has to earn the right to edit one: it maps each live URL to the file that produces it, checks that the file's title matches the page, and opens a pull request only when the match holds up (a page with no title to compare is matched on its path alone). When it is not, you get a note instead of a guess.
Every field, limit and safeguard is on the GitHub integration page.
Requirements
GitHub
A site whose pages live in a GitHub repository as HTML or Markdown files, and permission to install a GitHub App on that repository. The app asks for access to contents and pull requests on the one repository you choose.

Frequently Asked Questions
Can Hermes Agent fix SEO on my GitHub site?
Yes, through SEOmatic. Hermes Agent reads your Search Console data, finds the HTML pages and Markdown posts losing clicks and stages the fix, which SEOmatic writes to GitHub once you approve. The three setup steps are on this page.
What can Hermes Agent change on GitHub?
SEOmatic works on your HTML pages and Markdown posts through pull requests on your repository: titles, descriptions and content first, and more where GitHub allows it. Every field and limit is listed on the GitHub integration page.
How do I know if a GitHub fix worked?
SEOmatic measures every change it ships against the page's own baseline and your site's trend, 14 days after a title change, 28 after a content refresh and 90 after a new page, and marks it verified, ineffective or regressed. Hermes Agent can read those verdicts for you.
What do I need on the Hermes Agent side?
Hermes Agent installed and set up, and a free SEOmatic account. For a server with no browser, create an API key in Settings, AI Agents, API Keys.
Will Hermes Agent publish to GitHub 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. Search Console reports, page checks and 30-page site audits are free, as often as you like; live market data uses free questions, 5 a month plus a one-time 10 when you connect Search Console. Staging and publishing fixes is part of paid plans, which start with a 14-Day Trial for $1, credited to your first payment.
