Study 1 — Validation Interval 1: High-Intent GEO Pricing Query

Prompt Tested

“What is the cost of generative engine optimisation in the UK?”

Validation Date

10 December 2025, following the original live screen test recorded on 19 September 2025.

Core Finding

NeuralAdX Ltd remained visible in Google AI Mode, Perplexity AI and ChatGPT, while Microsoft Copilot did not show a visible NeuralAdX Ltd result in this specific validation test.

Hello and welcome back. It’s Paul Rowe here from NeuralAdX Ltd.

We are about to run our second live screen recording test, following up on the very first one we carried out using the prompt:

“What is the cost of generative engine optimisation in the UK?”

That initial live screen test was completed on 19 September 2025. We are now on 10 December 2025. If you look at the screen, I will refresh the browser so you can see that this is live and that I am being fully transparent. As you can see, the date is correctly showing as 10 December.

So, from 19 September 2025 to 10 December 2025, that is almost three months, give or take around nine days.

Now let’s go to the first tab, which is set up to test Google AI Mode. I am going to paste the same prompt into the browser and select Google AI Mode so we can see whether NeuralAdX Ltd still appears as it did previously.

Right, well, straight away in the top-right corner you can see our company, NeuralAdX Ltd, together with our logo. So we are appearing as a featured image result, which means users can click through to us immediately. That is an excellent result.

In the actual source links, we are appearing in position number three, which is still a strong and prominent placement.

Let’s look further through the text and see whether our links are being surfaced early within the response. In this section, it is not providing a definitive direct link to our site in the paragraph itself, but it is showing that our content is part of the set of resources used in the response.

Moving further down, we can see another group of resources connected to this section. And when I continue further, again we can see that NeuralAdX Ltd is part of the source mix referenced in relation to this comment.

So overall, that gives us the feedback from Google AI Mode. I would say that is a very solid result, especially because Google AI Mode is such a major and heavily used AI search environment. Just being surfaced prominently there is a strong outcome.

Next, let’s move into the second platform, which is Perplexity AI. I am going to paste in the same prompt and see what response we get.

That is absolutely brilliant.

Straight away, in the very first paragraph, you can see our organisation, NeuralAdX Ltd, and we appear as the number one source. That is an outstanding result to see happen live.

If we scroll further down, we can also see mentions of other companies, but NeuralAdX Ltd is mentioned again with another link. So that is a second mention.

Further down again, in this next section, we are mentioned two more times. There is our link again, and then again for a second time in that section.

So across the Perplexity AI result, we are mentioned four times in total.

And if we look at the sources list at the bottom, NeuralAdX Ltd is also shown as number one in the list of ten sources.

So yes, I am very, very pleased with that result. Extremely pleased. It is a great feeling to see that the time, effort, and consistent work are clearly paying off.

Now I am going to move to Microsoft Copilot and run the same prompt there.

Okay, so in Microsoft Copilot, the first response mentions First Page Sage. Scrolling further down, let’s see whether any other organisations are mentioned.

I have not used Microsoft Copilot very much apart from a small test run earlier today, and it definitely looks like the way it presents information has changed. But unfortunately, NeuralAdX Ltd is not being shown in this result.

It does mention First Page Sage again, and also Passion Digital.

So on this occasion, we did not achieve a visible result in Microsoft Copilot. That gives me something to re-optimise for, and I will need to look into that further.

Now let’s move into ChatGPT.

We are now in ChatGPT, so let’s enter the same prompt and see what happens.

Be kind to us.

Oh wow. Straight away, I saw it.

That is absolutely beautiful.

At the very top, the first company mentioned is NeuralAdX Ltd. Wonderful.

And the second link is also NeuralAdX Ltd.

That is an immediate confidence boost after Microsoft Copilot was not quite so kind.

We can see other companies mentioned lower down, but looking through the rest of the result, there are no additional direct mentions of our company name in the main body text.

However, in the sources at the bottom, NeuralAdX Ltd is listed again, and importantly, we are shown as the number one source in the list.

That is another excellent signal.

Also, further down, we can see that ChatGPT is actually drawing on two separate pieces of content from our website. One is our Generative Engine Optimisation pricing page published on 11 November 2025, and the other is our Generative Engine Optimisation Pricing UK article published on 13 September 2025.

So ChatGPT has used two separate NeuralAdX Ltd articles in its sourcing.

That is a very strong outcome because it shows that our content is being indexed effectively, recognised across multiple pages, and selected as relevant source material for AI-generated responses.

So, as you can see, over a period of almost three months, give or take nine days, NeuralAdX Ltd is still performing extremely well across the four AI platforms used in these live screen recordings:

Google AI Mode

Perplexity AI

Microsoft Copilot

ChatGPT

And I hope this helps validate that Generative Engine Optimisation really does work.

To be blunt, I cannot think of a much more genuine or transparent way to prove it. If you are watching this and want to verify the results for yourself, then run the same prompt directly in the specific AI chatbots and compare what you see.

Because when you can observe the results with your own eyes, not just through a screen recording but through your own live test, that gives even stronger confirmation of the benefits that can be achieved through effective, extensive Generative Engine Optimisation.

All right, guys and gals — equal opportunities.

I am going to sign off now, but thank you very much for watching, and I will see you in the next one.

Thank you so much.

Bye-bye.
