AI SEO as a production method
Content made with AI tools
SEO pages produced with AI tools, often in large numbers. The aim is more pages for the same budget. It says nothing about whether AI systems name your company.
AI SEO
21x is an AI SEO agency that works on two channels at once: AI answers and Google. That means being named by ChatGPT, Gemini and Perplexity, and being found in classic search results. It does not mean SEO content written by AI tools.
An AI SEO agency works on visibility in AI answers from systems such as ChatGPT, plus classic SEO for Google. At 21x it does not mean content written by AI tools. Both channels are measured.

What AI SEO means
The term AI SEO is used for two different things. Which one an agency means determines what you pay for.
AI SEO as a production method
SEO pages produced with AI tools, often in large numbers. The aim is more pages for the same budget. It says nothing about whether AI systems name your company.
AI SEO at 21x
Being named in the answers of ChatGPT, Claude, Gemini and other AI systems, and being found in Google. Both are measured, per system and per month.
21x does not sell content by volume. What you pay for is measured work on two channels, with a report that shows both.
How it works
One plan for two channels, because much of the groundwork is shared.
Your Google rankings and your visibility in six AI systems, side by side. The AI part uses 30 non-branded questions: in English for English-speaking markets, phrased as English-speaking buyers phrase them, and in Dutch for the Dutch market.
A site that crawlers can read, with fast pages and a clear structure, helps in Google and in AI answers. 21x starts here, because one fix serves both channels.
Consistent company details on your site, platforms and directories. AI systems combine many sources, and conflicting details make it harder for them to describe you correctly.
Pages that state facts clearly, quote sources and include figures with a source. In a controlled study, these changes increased visibility while keyword stuffing reduced it.
One monthly report with Google and AI answers side by side. You see where they move together and where they diverge.
Why both channels are measured
Example with fictitious data. Each row is one customer question, with the company's Google position and how often six AI systems named it in 30 attempts.
This is why 21x reports the two channels separately. Optimising for one and assuming the other follows leaves gaps you cannot see.

attempts across five questions. The question where the company ranks first in Google is the one where AI systems never name it.
What it costs
You can start with the audit, with SEO, or with both. Which comes first depends on where you stand in each channel.

Both channels share much of the groundwork, so work on one often helps the other.
Where traffic and answers come from
Two sources, two angles. One shows where website visits come from, the other which AI chatbots people use.

Google still delivers most visits, so classic SEO stays part of the work. Among AI chatbots, ChatGPT and Gemini together hold about four fifths of the market. AI SEO that ignores either channel leaves out a large part of where buyers look.
Questions
Some do, and they use the term for exactly that. At 21x, AI SEO means visibility in AI answers combined with classic SEO. You pay for work on both channels that is measured every month, not for a number of pages.
That depends on the size of your site, the competition in your market and what the audit shows needs work. You can start with one channel or work on both from the outset. The packages show the options, and you know the cost before work starts.
The terms overlap. GEO, short for generative engine optimisation, is the term used in research and covers visibility in AI answers only. AI SEO, as 21x uses it, combines that with classic SEO for Google.
21x makes no forecast about that. According to Cloudflare Radar, Google still sent more than 87% of search referrals to websites in July 2026, and ChatGPT 0.9%. Working on both channels means you do not depend on one.
ChatGPT, Claude, Gemini, Perplexity, Google AI Overviews and Microsoft Copilot. Results are split per system, since one may name your company where another names a competitor or nobody at all.
No. The same question can produce different answers from one day to the next, outside any agency's control. 21x measures where you stand, does the work the measurement points to and shows each month what moved.

In a call you hear whether the audit or SEO comes first for your company. If neither makes sense yet, you will hear that too.
