AI agents for marketing agencies

What an AI agent does for a marketing agency

An AI agent does one piece of an agency's work the way a member of staff would, inside rules the agency has written down for it. We build two that fit the way an agency runs: one does the weekly search work on a client's site, and one records the agency's own supplier invoices in its books.

We build each one for you rather than selling you a product to configure yourself. You tell us how the work is done today and how you want it done; we build the agent, you watch it work on your real work, and we keep it running from then on. If the job you have in mind is a different part of the agency, new-business enquiries or client reporting say, tell us on the consultation and we will say whether an agent can do it well.

Client SEO, done every week

The AI SEO agent reads a site's own Search Console data, decides which pages are worth working on this week, and makes the on-page changes that follow. It finds the pages with plenty of impressions and too few clicks, the queries sitting just off the first page and the answers a page almost gives, then rewrites the title, the meta description or the paragraph that should answer the query, and writes down what it changed and why.

That is the part of an SEO retainer that slips first. Every account manager knows which client pages underperform; the work nobody gets to is sitting down with each of those pages, every week, for changes that each look too small to schedule. An agent does those small jobs while the data is still fresh, and leaves your team the strategy, the client conversations and the pages that need a person.

For an agency the sites are your clients', so we agree the rules client by client before the agent touches anything real: the queries each client actually wants, the pages that must never change without a person looking, the claims a client has not approved, and whether a change goes live on its own or waits for sign-off. Where a client's content management system lets another program write to it, the agent makes the change itself; where it does not, it prepares the edit for someone on your team to paste.

A ledger your clients can read

Every week the agent leaves one dated line per page: what it found, what it did or chose not to do, and what it expects to see change. The pages it deliberately leaves alone are written down too, with the reason, so nobody pays twice to rediscover that a query belongs to a platform or that an established brand will win it whatever the page says.

That ledger is how you audit the agent instead of trusting it, and it is the record of work a client asks for at the monthly review.

What our SEO agent has done

We run one on a live marketing news site, The Keyword, where every article is written by agents and the SEO agent works on the pages they publish each week. Its case study shows the record: the data it pulls, the pages it changed, and the pages it left alone with the reason written out.

Answer engines as well as Google

People now ask an AI assistant the questions they used to type into a search box, and the assistant answers from pages it can read and quote. So the agent works both sides. For search it works on titles, descriptions and the match between a page and the query it is closest to winning; for answer engines it works on whether a page states its answer plainly, near the top, in a sentence an assistant can lift. It also watches which assistants send a site visits, so that work is measured rather than assumed.

The agency's own invoices, coded to your rules

The AI invoice processing agent reads a supplier invoice the way a person would. It takes the supplier, the invoice number, the date, the net, the VAT and the total off the page, decides which account and which VAT treatment it belongs to under rules you have set, and records it in your accounting software where that software lets another program write to it, or as a file ready to import where it does not.

An agency's suppliers are a long list of software subscriptions, freelancers and media costs, many of them billed from abroad, and that is exactly where VAT gets awkward. The rules are the ones your accountant would give a new bookkeeper, written down with you before the agent records anything, and anything they do not cover, a new supplier or an amount above the limit you set, goes to a person with the invoice attached rather than into the books as a guess.

What the invoice agent has done, and whose books they were

Up to 29 October 2026, an AI bookkeeping agent we built recorded 14 supplier invoices for TripleDouble, a marketing agency and consultancy, for under 5p each in AI model costs, against about £2.54 each for a bookkeeper doing the same work by hand. The hand figure is 9 minutes at £16.92 an hour.

That is a small number of invoices, and we would rather show you a small true number than a big round one. It worked from 7 written rules, drawn from the accountants' answers and the agency's own, and every entry it recorded names its rule, so anyone checking the books can see why it went where it did. It attached the invoice PDF to every entry, and anything the rules did not cover went to a person. The TripleDouble case study shows it invoice by invoice.

Your clients' data

We handle your data under UK GDPR, and we walk you through exactly where it goes on the consultation. The SEO agent can only reach the Search Console properties and publishing systems you approve for each client, and the invoice agent only the inbox, folders and accounting software you approve. You can withdraw any of that access at any time.

How we build it, and how long it takes

We build the agent around your real work, and you see it working on that work before it does the job on its own. Here is how it runs.

1. A 30-minute consultation. You tell us which clients' sites the search work is for, or how supplier invoices reach the agency, and where it goes wrong today. We tell you what we would build and give you the price.
2. Scope. We watch how the job is done today and agree what the agent will do: each client's rules, or your coding and VAT rules.
3. Build. We build it inside the tools you already use, connected to Search Console, the client's publishing system, your inbox or your accounting software where those tools allow it.
4. Test. It runs on your real work, checked by us, until it gets it right. The SEO agent goes over pages your team has already worked on, so you can compare what it would write with what you wrote; the invoice agent goes over invoices you have already recorded.
5. Live. It does the job on its own, and we keep it working.

Whether it writes straight into a client's content management system or your accounting software depends on what that system lets another program do; where it cannot, the agent prepares the work for someone on your team to paste or import. Working in 30 days, or you pay nothing more until it is.

What it costs a marketing agency

Agent Place charges one flat monthly fee for unlimited agents: the SEO agent, the invoice agent, and any other you want after them, for the same fee, month to month. We give you the price on the call.

We set it on the consultation once we know what the agents must do and how many client sites they work on. The usage is in the fee, so you pay nothing per page or per invoice, a busy month costs the same as a quiet one, and you can stop any month. Working in 30 days, or you pay nothing more until it is. The pricing on our homepage works the same way for every business we build for; there is no surcharge for agencies. What an AI agent costs sets out how that compares with the other ways of buying one.

Tell us where the agency's time goes

Tell us which client work keeps slipping, or how supplier invoices reach the agency today, and what you would like done with each. We will tell you on the call whether an agent is right for your agency, what we would build, and the price.

Unlimited agents. One flat monthly fee. Working in 30 days, or you pay nothing more until it is.
