description: Build a fast, on-brand landing page or small marketing site from the brand profile, ready to host on your own site.
---

Builds a fast, accessible landing page (or a small marketing site of a few pages) whose structure follows from the one action that counts as a win, and whose words come from the business profile Maggie already holds. The result is a page plan, finished copy and production-ready HTML/CSS that the user hosts on their own site (their website, host or site builder), with a checklist to verify it once it is live. CMO.so supplies the business facts and proof but does not host or publish landing pages: it publishes blog posts only.

When to use

  • "Build a landing page for X", "one-pager for my service", "campaign page", "waitlist page", "rebuild this page".
  • A new offer, event or product needs its own page before ads or emails go out.
  • Not for: improving an existing page without rebuilding it (cmo-page-cro), copy only (cmo-copywriting), checking ad-to-page match (cmo-landing-page-audit), or a full e-commerce store or logged-in app.

What is the Landing page builder skill?

Build a fast, on-brand landing page or small marketing site from the brand profile, ready to host on your own site.

It's one of cmo.so's open Conversion skills: a SKILL.md file that tells an AI agent when to use it, what to ask you first, the steps to follow, the checks to pass and what to hand back, so the job is done the same careful way every time.

When should I use it?

Reach for it when you'd otherwise say something like “Build me a landing page for this offer”, “Make a one-page site for my business”, “I need a page for my campaign”. Your agent reads the skill's description and picks it for requests like these, so you don't need to name it.

If a request is close but not quite right, the skill says so and points to the related skill that fits better, instead of forcing a poor answer.

What do I need to give it?

It works best with the single action the page is for, and the offer; business profile from CMO.so (`brand_get`) or a short pitch from the user; where traffic will come from, and any ad or email copy that will link to it; and brand colours, fonts, logo and real photos or screenshots; where it will be hosted.

You don't have to prepare everything up front. The skill asks for missing pieces one at a time and says plainly when it's working from an assumption instead of your data.

What do I get back?

You get page plan: archetype, section order, proof and CTA placement; final copy for every section; and a self-contained, responsive, accessible HTML page (or a small multi-page site) plus a pre-launch and post-launch checklist for hosting it on their own site.

Every result comes from a written method with a quality bar, so numbers name their source, claims are checked and the output is ready to use or share rather than a rough draft.

Is it free?

Yes. The skill is open source under the MIT licence, so you can use it, change it and share it, including for client work.

Seeing, copying and downloading the whole file on cmo.so needs a free sign-in. Copying also upvotes and saves it, so you can find it again under Saved on the skills page.

Which AI agents can use it?

Claude Code installs it from the cmo.so marketplace. Any agent that reads SKILL.md folders, such as Codex or Cursor, can use it once the folder is in its skills directory.

You can also paste the copied skill into ChatGPT, Claude or any assistant at the start of a conversation and ask it to follow the skill.

How do I install it?

In Claude Code, run /plugin marketplace add AI-Marketing-OS-LTD/cmo-so-skills, then /plugin install cmo-so-cro@cmo-so. That installs this skill together with the rest of the Conversion group.

For other agents, sign in, press Copy or Download above and put the file in your agent's skills folder as SKILL.md inside a folder named after the skill.

Do I need a cmo.so account to use it?

No. The skill works on its own with whatever your agent can already see and do: your files, the pages you share and the data you paste in.

With cmo.so connected it can go further, using tools such as brand_get, testimonials_change, testimonial_upsert through the MCP server. Every change is previewed and confirmed before it happens.

Which skills work well with it?

It pairs well with Conversion copywriting; and Page conversion optimisation. The agent can hand over from one to the next in the same conversation, for example research first, then the plan, then the writing.

Each of them has its own page with what it needs and what it returns, linked below.

Can I change it to fit my business?

Yes. It's a plain Markdown file, so you can edit the steps, add your own checks and examples, and keep your version in your own repo. The MIT licence allows it.

If your change would help others too, suggest it on the skills page or open a pull request on GitHub, and it may be folded into the library for everyone.

Where does the method come from?

It's written by cmo.so and adapts open work by others, credited on this page: nurkamol/website-build-kit (MIT); nurkamol/website-build-kit (MIT); and eibrahim/landing-pages-resources (no license).

Only permissively licensed work is adapted; copyleft repos are used for ideas only and repos without a licence aren't used at all.

Is my data sent to cmo.so when the agent uses it?

No. The skill only guides your own agent; your files, documents and data stay wherever your agent and its tools keep them.

cmo.so only sees what you connect to cmo.so. Your votes and saves on this page are stored against your cmo.so sign-in.
