where marketing fails

Marketing fails when nobody joins the channels up

Marketing fails when three channels sit in three agencies, reports hide what a lead costs, and the work stops when the invoice stops.

[ 01 ]

Three agencies for three channels

SEO, ads and AI visibility each have a vendor. Nobody joins the plan up, so you pay three times for work that pulls in different directions.

01Split vendors
[ 02 ]

Reports that hide cost per enquiry

Rankings, impressions and click charts look busy. They do not tell you what a lead cost, or whether the month was worth it.

02Vanity reports
[ 03 ]

Content nobody searches for

Blog posts and service pages that answer no real search. Volume without intent wastes crawl budget and budget.

03No intent
[ 04 ]

AI answers recommending competitors

Buyers ask ChatGPT, Claude or Google AI who to hire, and a competitor gets named. You never see the miss.

04AI gap
[ 05 ]

Ad budget with no tracking

Spend goes out while conversion tracking is broken or counts the wrong things. You cannot tell what each pound bought.

05Blind spend
[ 06 ]

Marketing that stops when the invoice stops

The retainer ends and so does the work. Nothing compounds in your site, your accounts or your data.

what is an ai marketing agency

What is an AI marketing agency?

An AI marketing agency is an agency where AI agents do the repetitive marketing work under human direction, so more of your budget goes on the work and less on the hours. At Code23 that means agents run audits, monitoring, drafts and Ads builds, while a senior person decides, signs off and is accountable for every change.

Code23 is a strong fit when

  • UK businesses that need search, AI answers and paid ads joined up under one plan.
  • Teams tired of three vendors for three channels and reports that hide cost per enquiry.
  • Owners who want agents on the routine work with a named person accountable for every change.
  • Firms ready to share GA4, Search Console and ad account access so measurement is honest.

We may not be the right fit when

  • Anyone wanting a chatbot to run marketing with no human sign-off.
  • Anyone wanting a guaranteed ranking, citation or cost per lead before we have seen the data.
  • Businesses that will not share analytics or account access for measurement.
choosing an agency

Evidence to check before you choose

  • 01 Ask who signs off every change, and what happens when something breaks.
  • 02 Ask what the agents do and do not do, in plain language.
  • 03 Ask what you see each month, and whether cost per enquiry comes first.
  • 04 Ask who owns the accounts and data if you leave.
what we do

AI-assisted marketing across search, answers and ads

AEO and AI visibility

Get recommended by ChatGPT, Claude and Google AI. We measure who appears instead of you, then close the gap.

SEO and content

Rankings you can measure. Technical fixes shipped in your codebase, pages that answer real searches, reporting in Search Console and GA4.

Google Ads and Shopping

Campaigns on your own account, with landing pages that match the ad and conversion tracking that shows cost per enquiry.

Landing pages and conversion

We build the pages. The promise in the ad or the search result is the first thing on the page.

Measurement in your own analytics

GA4, Search Console and the analytics you already use. You keep the data. We report cost per enquiry first.

Social plan that supports search and paid

A social plan inside the wider marketing work, not a standalone route. It backs the search and paid channels you already chose.

How we work

First we find the gap, then we work it

Six steps from a free snapshot across the three channels to a monthly report with cost per enquiry first. You always know what we measured, what we changed, and what comes next.

Step 1

01 - One snapshot across the three channels

AI answers, rankings and ads waste on one page. You see which channel is the biggest gap before you spend more.

Step 2

02 - Pick the route with the biggest gap

AEO, SEO or Google Ads. Start where the miss is largest, not where the loudest vendor pitches.

Step 3

03 - Agree what a lead is worth

Before we change more, we agree what an enquiry is worth to you and what success looks like in numbers.

Step 4

04 - Agents run the routine work, people decide

Agents draft, monitor and build the routine pieces. A senior person decides what ships and owns the result.

When AI consultancy can help and when a business may be ready to build
Signal Go No-go
You need enquiries this quarter Start with Google Ads. Buy the searches people already type, with landing pages and tracking that show cost per enquiry. Do not wait for SEO alone if the pipeline has to move this quarter.
Buyers research you in ChatGPT Start with AEO. Measure who assistants name today, then close the citation gap. Do not pour more blog volume into classic SEO alone if the miss is inside the answer.
Your site was never audited Start with SEO. Crawl, index and content problems block every other channel. Do not scale ads or chase AI citations on a site Google cannot read cleanly.
You sell nationally in a competitive market Usually SEO plus AEO together: rankings you can measure, and citations inside AI answers. A local-only plan will not cover national demand.
You sell locally in Reading or Berkshire Local SEO and Google Business Profile first, then ads for the phrases that already convert nearby. A national content mill will not beat a clear local presence.
You already run ads Start with a free Google Ads review. Cut waste and fix tracking before you raise spend. Do not add budget on top of broken conversion tracking.

SEO vs PPC: which should a UK business pay for first?

We've recently completed Phase 1 of a bespoke business valuation tool with James at Code23, and I've been extremely impressed. He has taken the time to understand both the commercial and technical requirements, communicated clearly throughout, and delivered a well-thought-out system with a high level of flexibility. The admin dashboard, in particular, gives us full control over the scoring and valuation logic, which was a key requirement. I'm looking forward to working with James on Phase 2 and would have no hesitation in recommending him to anyone looking for bespoke software development – Jason Atkins, Director, Lansley Commercial

We couldn’t be happier with the service from Code23. They were a pleasure to work with—friendly, professional, and really took the time to understand our needs. They met our brief perfectly, delivering a website that looks great and performs exactly as we envisioned, all at excellent value for money. What sets Code23 apart is their aftercare. Knowing they are on hand to monitor and maintain our website means we never have to worry about its performance. Their ongoing support gives us complete peace of mind, and we’d highly recommend them to anyone looking for a reliable and skilled web development team

It has truly been a fantastic experience working with the Code23 team. Every part of the process from the scoping and onboarding down to the design and implementation of our website was handled excellently. The quality of service delivered by the team is globally top standard and I couldn't be more satisfied with the final outcome.

AI marketing agency questions

What is an AI marketing agency?

An AI marketing agency is an agency where AI agents do the repetitive marketing work under human direction, so more of your budget goes on the work and less on the hours. At Code23, agents run audits, monitoring, drafts and Ads builds. A senior person decides, signs off and is accountable for every change.

How much does a digital marketing agency cost in the UK?

Our free marketing snapshot is free and arrives in 48 hours. The AI visibility audit and the technical SEO audit are each £1,500 + VAT fixed. Google Ads reviews are free. Management and ongoing work are agreed after you have seen the gap on the route you choose. We do not publish retainer figures here because the scope depends on what the snapshot and audit find.

What do the AI agents actually do?

They run the routine work: audits, monitoring, draft copy, Ads builds and checks across search, AI answers and paid. They do not decide strategy, approve live changes or own the client relationship. A senior person does that.

Who is accountable when something breaks?

A named senior person at Code23. Agents draft and monitor; people decide what ships. If a change causes a problem, that person owns the fix. You are never left talking to a bot about a live issue.

Do you do social media?

Yes, as a social plan that supports the search and paid work, not as a standalone route. Social sits inside the wider plan so it backs the channels that bring enquiries, rather than running as a separate vanity feed.

Do you work with businesses outside Reading?

Yes. We are based in Reading, Berkshire, and work with clients across the UK. Workshops and reviews can run remotely or in person.

Is digital marketing still worth it in 2026?

Yes, when you can measure cost per enquiry and you start on the channel with the biggest gap. Google still sends high-intent visits, AI answers now shape early research, and paid search still buys pipeline this quarter. The miss is usually joining those up, not picking one slogan.

SEO, AEO or Google Ads first?

Choose Google Ads when you need enquiries this quarter. Choose SEO when the site was never audited or you need rankings you can measure. Choose AEO when buyers already research your category in ChatGPT, Claude or Google AI. The free marketing snapshot shows which gap is largest for you.

Which AI agent is best for marketing?

None on its own. The person directing it matters more than the model. We use agents for routine audits, drafts, monitoring and Ads builds. A senior person sets the brief, signs off every change and owns the result.

Can I hire an AI agent?

You can buy tools that call themselves agents. What we sell instead is marketing work with agents inside the process and a senior person accountable for every change: snapshot, route audit, then ongoing work on AEO, SEO or Google Ads in your own accounts and site.
