Claude for marketing

How we rebuilt thecmo.ai in a day to show up in ChatGPT

On September 23, 2026 we asked a simple question: if someone asks ChatGPT for an AI marketing system for agencies, could it name us? The honest answer was no. Here is everything we changed, done with Claude, in one day.

The results are not in yet. We will add them here when they are.

By Nathan, who built TheCMO and runs an agency on it. Written from what we use every day, September 2026.

Step 1: check whether ChatGPT could even see us

ChatGPT’s search reads Bing, not Google. So the first check was Bing Webmaster Tools, not Search Console. Bing had the site: six of eight pages indexed and crawled the day before. Our robots file let every crawler in.

So visibility was not the problem. The words were.

Step 2: read the page the way ChatGPT reads it

We fetched our own page as a crawler would and read only the text. Three problems:

  • The homepage sold a texting service to local businesses, an offer we had just retired. The words “agency” and “brand” did not appear once, and that is who we sell to.
  • Three old pages still sold offers we had stopped selling.
  • Search engines carried a third description of us from an even older version. Three stories about one company.

An answer engine can only repeat what you say about yourself. We were saying three different things.

Step 3: one story, said plainly

We rewrote the homepage around one sentence and repeated it everywhere:

TheCMO is an AI marketing system for agencies and companies. It does the work across Google Ads, Meta Ads, SEO, content, websites and Shopify, follows your own playbook, asks before it changes anything live, and keeps a record of every change.

  • The same sentence opens the page, the FAQ, the structured data and llms.txt.
  • Every FAQ answer stands on its own, because that is the part that gets quoted.
  • Old offer pages were removed and redirected to the homepage, so their links still land somewhere.

Step 4: fix the plumbing nobody looks at

  • A canonical pointing at a redirect. Our pages told search engines the real address was thecmo.ai, but thecmo.ai redirected to www.thecmo.ai. Mixed signals. We moved everything to the address that actually serves.
  • IndexNow. One request tells Bing which pages changed. It answered 202, accepted.
  • Structured data. Organization, software and FAQ markup, saying the same thing as the page.
  • Unreadable legal pages. Our privacy page had light grey text on a light background, left over from an old design. Nobody had noticed. Google reads that page when it reviews an app’s access, so it mattered.

Step 5: a product page that proves itself

The product page answers the question a buyer now asks first: isn’t this just a bundle of AI skills? Every number on it was checked against the product that day, and a note in the page’s source says where each came from.

We also caught ourselves overclaiming. The first draft described a feature that takes work off you step by step as if it were live. It is not built yet. The page now says “this is what we are building next”, which reads as more credible, not less.

Read the product page

Step 6: find out what people actually search

We pulled about 15,000 keyword ideas straight from Google’s Keyword Planner through the Google Ads API, five years of Google Trends, and the “People also ask” questions for 32 topics. The paid data cost about nineteen cents.

  • “ai marketing” and “ai seo” went from almost nothing in 2021 to mainstream.
  • “generative engine optimization” (4,400 a month) and “answer engine optimization” (2,400) are real markets now.
  • “claude for marketing” grew about seventeen-fold in a year.
  • Some big numbers are traps. “roas” shows 3.35 million searches, and the results page is Ross Dress for Less.

Those findings became the guides on this site, starting with these.

Step 7: check before calling it done

  • Screenshots at desktop and phone width, read before shipping.
  • A copy linter that blocks the tells of machine writing. It caught one on a page we had not even touched.
  • Every old address tested live to confirm it redirects.

What we will report back

Whether Bing picks up the new pages, whether ChatGPT describes us correctly, and whether it starts naming us for the questions above. We will check a fixed set of prompts and post the answers here, good or bad.

Straight answers

How do you get a website to show up in ChatGPT?
Make sure Bing has indexed it, since ChatGPT’s search reads Bing. Let the AI crawlers in. Then say plainly on the page what you are and who you are for, in sentences that can be quoted on their own, and get named on the third-party pages ChatGPT already trusts.
Does llms.txt help with ChatGPT?
It is cheap to add and gives an assistant a clean summary of your site. We added one. Nobody has shown it moves rankings on its own, so treat it as tidy, not magic.
How long does it take to show up in ChatGPT?
Changes reach Bing within days if you ping it, and ChatGPT’s answers follow over weeks. Being mentioned on other sites takes longer. We will update this page with what actually happened.
