AI ads + context engineering

Be the business the AI recommends.

People now ask ChatGPT, Gemini and Grok who to trust. We engineer the context those assistants read and run the ads that sit beside their answers, together.

Illustration of an AI chat. A person asks for a good implant dentist in London. The assistant searches the web and recommends Your business here for three reasons, each with a source link to yourbusiness.co.uk. A sponsored unit for Your business here offers to book a consultation. The person asks about a consultation this week, and the assistant says they can book a slot online.

The market, as reported

The questions moved. So did the ads.

AI assistants are where people now ask for advice, and the platforms have started selling space next to the answers.

What are AI ads and context engineering?

AI ads are sponsored units next to an AI assistant's answer, for example in ChatGPT, where the platform offers them. Context engineering makes sure assistants know, trust and cite your business. We run both together for clinics, B2B suppliers and professional firms. Management starts from £3,800 a month. Ad spend is paid to the platform.

Prices exclude VAT. Final price after we analyse your business and scope.

Your nearest consultant

From ten blue links to one trusted answer.

People ask an assistant the questions they used to ask a friend or an expert. By the time it recommends someone, they are close to a decision.

Search 2015

Ads, ten links and a row of open tabs. The person still has to compare it all and decide alone.

Intent: browsing

AI assistant now

One conversation, follow-up questions, one recommendation and a booking.

Intent: deciding

People tell an assistant their budget, their worries and their timing. That is why a recommendation in that moment carries more weight than a search result.

Two engines, one answer

Context and ads, built together.

One team works on what the assistant knows about you and on the sponsored unit next to its answer, at the same time.

Both, in the same conversation.

Context engineering, explained

Five layers the assistant reads about you.

Assistants piece together an answer from what they can find and check. We build each layer so the facts about you are clear, consistent and easy to cite.

  1. LAYER 01

    Entity and facts

    One consistent set of facts about who you are, where you work and what you do, on every page and profile assistants read.

    Example deliverable: an entity fact sheet and fixes to your About, contact and service pages.

  2. LAYER 02

    Proof and pricing pages

    Pages that show your real prices, process and credentials, written so an assistant can quote them.

    Example deliverable: a consultation pricing page and a step-by-step process page.

  3. LAYER 03

    Structured data and feeds

    Schema markup and service or product feeds, so machines read the same facts people do.

    Example deliverable: organisation, service and FAQ schema, tested and live.

  4. LAYER 04

    Third-party citations

    Mentions on directories, press and partner sites that assistants already trust.

    Example deliverable: a citation plan, with the first listings made and wrong details corrected.

  5. LAYER 05

    Prompt testing across ChatGPT, Gemini and Grok

    We check what each assistant says about you every month, using the questions your buyers ask.

    Example deliverable: a monthly prompt report: named or not, cited or not, and who else appears.

Questions

Straight answers.

What is context engineering?

It is the work of making sure AI assistants have correct, clear facts about your business that they can check: who you are, where you work, what you do, what it costs and who can vouch for you. We fix it on your site, in structured data and on trusted third-party sites, then test what each assistant says.

Can you guarantee we appear?

No. Each assistant decides its own answers, and they change by person, by session and over time. Ad placements follow each platform's own auction and rules. What we can promise: the facts assistants read will be correct and easy to cite, the ads will be set up properly, and you will see every result each month, good or bad.

Which platforms do you work on?

ChatGPT, where self-serve ads are live. Google, with ads in AI Overviews and AI Mode. Grok, where ads in answers have been announced, and we set up as placements open. Context engineering also helps with Gemini and other assistants, because they read the same kinds of sources. We check what is available in your market before we start.

What does it cost?

Management from £3,800 a month for SME brands and from £7,500 a month for mid-market teams. Enterprise is priced to scope. Ad spend is paid to the platform, never part of our fee. Prices exclude VAT. Final price after we analyse your business and scope.

When did ChatGPT ads open?

ChatGPT ads ran as a beta from May 2026. The self-serve Advertise in ChatGPT portal opened on 22 July 2026.

How fast will we see anything?

The launch takes two weeks. Ads can start showing in the second week, where the platform offers them in your market. Context changes take longer to show, because assistants update what they know on their own schedule. Expect change over months, not days.

What do you need from us?

Access to your website and ad accounts, your services and prices, the credentials and partners you can prove, the questions customers usually ask, and someone who can reply to new enquiries quickly.
