What Is an AI Marketing Agency? Services & Costs

Two meanings of "AI marketing agency"

Most articles that define the term describe an agency that applies machine learning and automation to ordinary marketing work: targeting ads, generating content, analysing customer data and running chatbots. The client gets the same marketing outcomes, produced faster.

A newer kind of agency works on a different problem. Buyers now ask AI assistants which product to choose, and the answer usually names only a few brands. An agency in this group measures how AI systems describe your brand and improves the content, technical setup and outside mentions those answers draw on. This work is also called generative engine optimization (GEO), answer engine optimization (AEO) or AI SEO.

What an AI search marketing agency does

The work follows a measure, fix and re-check loop. It starts with the questions your buyers ask and ends with a report that compares the same questions month to month.

Audit: check how AI systems answer your buyer questions and who they name instead of you.
Content: write and rewrite pages so they answer questions directly and can be quoted.
Technical: make sure AI crawlers can read your site, and add structured data.
Outreach: get your brand into the reviews, roundups and directories AI answers cite.
Reporting: re-check the same questions and show what changed after each piece of work.

What it costs

Published prices for agencies that specialise in AI search start at about $2,500 a month and reach $8,500 to $10,000 a month for enterprise and B2B SaaS work, according to agency roundups. Many agencies, including Digraph, offer a one-off audit first, so you can see the gaps before committing to a retainer. Digraph's audit starts from $1,900 and its monthly retainers from $2,500.

How to choose one

Decide first which of the two problems you have. If you want faster campaigns, look for an agency that uses AI in production. If you want to be recommended in AI answers, look for one that measures AI answers directly.

Which AI systems does it measure, and how many times does it ask each question?
Can you see the actual answers and sources behind its reports?
What work does it do each month, and who does it?
How does it report results, and against which baseline?
Does it promise guaranteed placements? No agency can guarantee what an AI system says.

How Digraph works

Digraph is an AI marketing agency for AI search. We measure on our own platform, which checks 9 AI systems, including ChatGPT, Gemini, Claude, Perplexity, Microsoft Copilot and Google AI Overviews, and asks each question up to 250 times. Then our team does the content, technical and outreach work, and reports the same questions every month.

Common questions

What is an AI marketing agency?

A marketing agency built around artificial intelligence. Some use AI tools to produce marketing faster; others, like Digraph, work on how your brand appears in AI answers from ChatGPT, Gemini, Perplexity and Google AI Overviews.

What services does an AI marketing agency offer?

Agencies that use AI offer ad buying, content production, chatbots and analytics. Agencies for AI search offer AI visibility audits, content and technical fixes, outreach to the sites AI cites, and monitoring of AI answers.

How much does an AI marketing agency cost?

Published prices for AI search agencies start at about $2,500 a month, and reach $8,500 to $10,000 a month for enterprise work. A one-off audit is a lower-cost way to start.

Is an AI marketing agency the same as an SEO agency?

Not quite. SEO agencies work on Google rankings. An AI search agency also works on AI answers, which are measured differently. The foundations overlap, so many agencies, including Digraph, do both.
