Study 1 – Validation Interval 5: High-Intent GEO Pricing Query Video Transcript

On 19 September 2026, exactly 12 months after the first test in this series, NeuralAdX Ltd tested the query “What is the cost of generative engine optimisation in the UK?” across Google AI Mode, Perplexity, Microsoft Copilot and ChatGPT. NeuralAdX Ltd surfaced in Google AI Mode as a cited source and direct brand mention, appeared as the first domain citation shown in Perplexity with multiple NeuralAdX citations, and received a direct brand mention with a NeuralAdX domain citation in ChatGPT. NeuralAdX Ltd did not surface in Microsoft Copilot during this test.

Hello and welcome everybody.

Today is a very interesting day. It is 19 September 2026, exactly one year since we conducted our first live AI retrieval test across four major AI platforms: Google AI Mode, Perplexity, Microsoft Copilot and ChatGPT.

Today I believe will be our sixth test across this longitudinal 12-month period.

In our first test conducted on 19 September 2025, NeuralAdX ranked third in Google AI Mode and first in Perplexity, Microsoft Copilot and ChatGPT for this particular query.

However, the AI search market has changed significantly over the past year. Competition has increased considerably, so I am interested to see how NeuralAdX surfaces today.

In the previous live AI retrieval test for this query, I noticed that our AI visibility and citation performance had declined somewhat.

So let us see what happens today.

This type of longitudinal testing provides useful evidence of how AI answer engines continually change. AI-generated answers can vary over time as retrieval systems, source selection, recency, relevance and other signals change.

I am looking forward to seeing the results, although there is always the possibility that we may not perform as strongly as we did previously.

That would also be understandable because I have not specifically optimised for this query for approximately eight or nine months. I have largely left the content as it was when it was originally optimised.

So let us run the test and see what happens.

We are starting with Google AI Mode.

The query is:

“What is the cost of Generative Engine Optimisation in the UK?”

Let us see what happens.

Will NeuralAdX Ltd appear?

Wow. I have massively undersold our chances there.

As you can see in the source panel on the right-hand side, NeuralAdX Ltd appears as a source.

Looking at the citations, the first citation is not NeuralAdX, but the second citation is NeuralAdX Ltd.

That has really pleased me.

Moving further down the answer, we can see a pricing table showing an entry-level range of £450 to £1,250.

That reflects NeuralAdX’s published GEO pricing structure.

We deliberately offer a lower-cost introductory Generative Engine Optimisation package because GEO is still a relatively new industry and some businesses remain uncertain about investing in it.

The idea is to provide businesses with a lower-cost starting point so they can evaluate whether GEO produces value before moving to a larger package.

So I recognise this £450 to £1,250 pricing range as our published pricing structure.

NeuralAdX is also represented prominently within the pricing table.

Moving further down, we can see NeuralAdX Ltd mentioned directly, with a link to our content discussing the cost of Generative Engine Optimisation.

So I am surprised and very pleased with that result.

That is a strong result from Google AI Mode.

Now we are moving to Perplexity with exactly the same query.

“What is the cost of Generative Engine Optimisation in the UK?”

Let us see how NeuralAdX surfaces here and whether our visibility has stood the test of time on this AI platform.

I am genuinely pleasantly surprised.

Straight away, NeuralAdX Ltd appears together with our published GEO pricing structure.

NeuralAdX surfaces as the first domain citation shown here.

There are other organisations referenced within the answer, but NeuralAdX is displayed very prominently to the user.

It feels particularly fitting that on the one-year anniversary of this longitudinal AI retrieval testing, we are still seeing results like this.

The outcome could have been very different. We could easily have failed to surface at all.

So I am very pleased with this result.

Further down, NeuralAdX Ltd appears again with another domain citation and an excerpt from our content.

Perplexity then provides an example of agency pricing and specifically selects NeuralAdX Ltd.

It references our pricing from £450 to £1,250 per month before mentioning the higher pricing tiers.

There is then another NeuralAdX domain citation.

So this is an exceptionally strong performance in Perplexity.

I am very pleased with that.

Now we move to Microsoft Copilot.

Microsoft Copilot is slightly different for us because we have experienced issues with Bing Webmaster Tools for approximately six months.

Our business information has not been fully implemented correctly within the Microsoft ecosystem, and we have been trying to resolve that issue.

That may affect our ability to surface in Microsoft Copilot.

But let us see what happens today.

Looking at the initial answer, NeuralAdX has not surfaced.

There is a list of other agencies receiving domain citations, but NeuralAdX is not included.

Scrolling further down, I cannot see any NeuralAdX links or citations.

So in this test, NeuralAdX has not surfaced in Microsoft Copilot.

As I mentioned, there is an existing Bing-related issue that could potentially be relevant, although this test alone cannot establish the precise reason for the absence.

Now we move to ChatGPT.

Let us see how NeuralAdX performs for the same query.

If we can achieve three strong appearances across the four platforms, that would be an excellent result.

Two strong results already is encouraging.

Looking at the ChatGPT response, I can see some overlap between the sources being used by Microsoft Copilot and ChatGPT.

But here we have a direct NeuralAdX mention.

It says that NeuralAdX publicly published UK pricing currently starts with a free visibility test, then £450 a month for GEO Boost and £1,250 a month for GEO Growth.

That statement is accompanied by a NeuralAdX domain citation.

So NeuralAdX has been specifically named in context and directly cited as a source.

I am very pleased with that.

Overall, NeuralAdX surfaced in three of the four AI platforms tested today: Google AI Mode, Perplexity and ChatGPT.

We did not surface in Microsoft Copilot.

This test was conducted exactly 12 months after our first live AI retrieval test for this query and, to the best of my records, this is the sixth test in the series.

For this specific query and this specific optimisation work, that provides an interesting example of how Generative Engine Optimisation can potentially produce sustained AI search visibility over an extended period.

On the NeuralAdX Proof GEO Works page, we document the previous live AI retrieval tests conducted throughout this period.

That means these results are not based simply on retrospective claims.

Each test records how NeuralAdX surfaced across the AI platforms at a particular point in time.

This sixth test adds another observation to that longitudinal dataset.

It is therefore evidence relating to this specific query, this specific website and this particular GEO optimisation strategy.

I think that distinction is important.

Rather than making an absolute claim that every GEO campaign will produce identical results, it is more accurate to say that this series provides longitudinal evidence that Generative Engine Optimisation can contribute to sustained visibility and citations within AI-generated answers.

AI search results remain variable and can change according to platform, retrieval behaviour, competition, recency, source availability and many other factors.

But reaching the 12-month point with continued visibility across three of the four platforms tested is extremely encouraging.

It represents a considerable amount of testing, patience and ongoing analysis.

And when the results look like this, that effort is particularly rewarding.

Thank you very much for watching.

I look forward to seeing you in a future NeuralAdX video covering Generative Engine Optimisation, AI search visibility, AI citations and live AI retrieval testing.

Take care everyone.

Bye-bye.
