- A ranked list of fixes, biggest first
- Work you can see: pages, schema, listings, mentions

Why we rank TheCMO first
AI search does not reward a trick. ChatGPT, Perplexity, Gemini and Google AI Overviews name brands that are easy to understand and described the same way across the web. That takes clear pages, clean technical setup and real mentions on sites the models trust.
TheCMO runs that work with AI, next to the Google Ads and Meta ads that already pay the bills. Nathan has taken brands from five to seven figures with Google Ads, Facebook Ads and SEO. AI search is the next place buyers ask, so we treat it the same way: measured, tested, tied to sales.
The chart shows Nathan's Google Ads spend managed, 2018 to 2026. It is his paid ads record, not an AI search result.

How to choose an AI SEO agency
Use these questions on any agency on this page, including us.
-
Ask what they will change
A good agency names the pages, listings and mentions it will work on. If the answer is only "content" and "authority", ask again.
-
Ask how they measure it
AI answers shift by prompt, day and user. Ask for a fixed set of buyer questions, checked on a schedule, with screenshots.
-
Treat guarantees as a warning
Nobody can guarantee a mention in ChatGPT or an AI Overview. A promise like that tells you how they sell, not how they work.
-
Check their search basics
AI search still leans on classic SEO: crawlable pages, clear answers, structured data. Weak at SEO means weak here.
-
Find out who does the work
Ask whether a senior person runs your account or hands it to a junior team after the sale.
-
Tie it to revenue
Visibility is the means. Ask how they will connect AI referrals and branded search to sales you can see.
Questions buyers ask before hiring an AI SEO agency
What does an AI SEO agency actually do?
It works on the things AI tools read before they answer. That means clear pages that state what you sell and who it is for, structured data, a site crawlers can reach, and consistent mentions of your brand on other sites, listings and reviews.
Then it tracks a fixed set of buyer questions in ChatGPT, Perplexity, Gemini and Google AI Overviews, so you can see whether your brand shows up and how it is described.
Can any agency guarantee ChatGPT will recommend my brand?
No. Nobody controls what an AI model says, and answers change by prompt, by day and by user. An agency can make your brand easier to find, understand and trust. Treat any guarantee of a mention or a ranking as a warning sign.
How is AI SEO different from regular SEO?
Regular SEO aims for a ranked link. AI SEO aims to be the brand the answer names or cites. Most of the groundwork is shared: crawlable pages, clear answers, structured data. AI SEO puts more weight on how your brand is described across the whole web, because models learn from many sources, not just your site.
How long before AI search changes show up?
Fixes to your own site can be picked up within weeks, once crawlers revisit. Mentions on other sites and shifts in how models describe you take longer, often months. Anyone who names a date for a ChatGPT recommendation is guessing.
How much does an AI SEO agency cost?
Agencies price it as a monthly retainer, a one-off audit and fix project, or a mix. Cost depends on how much content, technical work and outreach your brand needs. We quote after the free review, once we know what the work is. Our guide to AI SEO pricing explains the models.
How can I check whether ChatGPT mentions my brand today?
Write down the questions a buyer would ask, like the best product in your category for a certain need. Ask them in ChatGPT, Perplexity, Gemini and Google, with a fresh session each time, and record who gets named. Repeat on the same day each month. Our free review does this for you.
Why does this site rank TheCMO first?
Because Nathan Synoground, founder of TheCMO, publishes it. We say so on every page. Every other agency listed is real and described only from its own website. Use the checklist on this page to judge all of them, including us.
Do you have AI search case studies?
Not published yet, and we will not invent them. The proof we can show today is Nathan's ad track record: $20.5M in Google Ads managed across 150 client accounts since 2018, and brands taken from five to seven figures with Google Ads, Facebook Ads and SEO.
