Gen AI Is Redrawing the Agency Map, and Not Everyone Will Like Where It Leads

The most interesting impact of generative AI on the agency world right now is not the tools it enables, but the power structures it is quietly destabilising.

As large language models increasingly mediate how brands are discovered, evaluated, and recommended, the assumptions that have underpinned agency models for the past twenty years are starting to fray. This shift is not confined to one discipline. It cuts across web design, performance, SEO, creative, media, and PR with significant implications for how agencies are built and valued.

What is changing is not demand for marketing, but the order in which influence, visibility, and conversion now occur, which is therefore shifting the power balance within the marketing mix.

When Discovery Changes, Everything Downstream Is Affected

AI-driven search does not behave like traditional search engines. Rather than directing users to a list of web links, LLMs synthesise answers, drawing on a wide range of third-party sources and signals to determine what is credible, relevant, and worth surfacing.

This has a profound knock-on effect as earned coverage, once the ugly cousin of the marketing mix, now holds all the cards. That inversion matters because it exposes which parts of the agency (and marketing) ecosystem control demand, and which respond to it.

What This Means for Different Agency Specialisms

Performance and media 

For performance and media agencies, the risk is not irrelevance, but dependency. As AI places greater emphasis on signals they do not directly control, these agencies may find themselves optimising conversion and efficiency within increasingly constrained parameters. Their opportunity lies in moving upstream through partnership or integration with disciplines that shape discovery in this new digital world.

SEO

SEO agencies face a more existential challenge. Traditional optimisation models, built around keywords, rankings and technical advantage, are under pressure as AI reduces the visibility of those mechanics. Content without authority becomes easier to replicate and harder to defend. The path forward is likely to involve a closer alignment with credibility, brand and earned influence: areas historically treated as adjacent rather than central to the marketing mix. 

Creative

Creative agencies sit in a more ambiguous position. Ideas matter more than ever as content generation and execution can be delivered in-house with the use of AI quickly and cost-effectively. 

However, the routes through which creative ideas travel are changing. Creativity that lives primarily in owned channels risks being contained, while ideas that gain third-party endorsement and cultural traction travel further and last longer now LLMs favour valuable earned sources. This pushes creative agencies to think more seriously about distribution, influence and earned amplification, not as add-ons, but as integral to the work.

PR

With all this in mind, PR agencies find themselves with a natural advantage. However, it will only materialise if they are willing to modernise. Earned authority is becoming more valuable, but only when it is understood, measured, and positioned as a commercial asset rather than an intangible benefit. 

PR agencies are about to, for the first time, really be able to prove attribution and ROI and those who are early adopters of tech to support this will take the advantage. However, long term, PR agencies will need to ensure they are both fit for growth and are able to partner with other disciplines in the new, more central role in the marketing mix. 

Across all of these agency specialisms, the message is the same: specialism alone is no longer enough.

This Moment Will Accelerate Mergers & Acquisitions in the Agency Industry

When industries undergo structural change, consolidation tends to follow, not least because our sector is over-saturated and bottom-heavy, but integration is about to become strategically necessary.

AI is accelerating the value of agency specialisms that combine influence, credibility and earned under one roof. Groups without PR capability are suddenly exposed. Agencies that rely heavily on a single downstream lever face increased risk. Smaller specialists may struggle to invest at the pace required to adapt alone.

In this context, M&A shifts from being opportunistic to strategic for survival.

Some agencies will acquire the capability to future-proof their offer. Others will seek partners that allow them to move upstream or downstream more effectively. For some founders, this period of flux will create an opportunity to exit on stronger terms than might previously have been possible, as buyers reassess where long-term value sits.

Importantly, this is not just about revenue multiples. It is about relevance.

The Founder Challenge: You Can’t Optimise Your Way Through This

One of the most common mistakes agency leaders make during periods of disruption is treating structural change as an optimisation problem. Tweaking services, experimenting with tools or rebranding propositions may buy time, but it rarely addresses the underlying shift.

What is required instead are decisions that cut across positioning, capability, culture and risk tolerance. Decisions about whether to build, partner, acquire or exit. Decisions that affect not just growth, but the owners’ personal ambition, leadership structure and long-term value.

These are difficult choices to make in isolation, particularly when the business is still performing well enough to mask emerging threats. Yet waiting for certainty often means surrendering control over timing and options.

This is where many founders quietly reach a crossroads: continue navigating alone, or bring in an experienced perspective to help sense-check assumptions, explore scenarios and support decision-making while the ground is moving.

The Advantage of Acting Before the Narrative Hardens

Every major shift in the agency world creates winners not through superior execution alone, but through early clarity. The agencies that act before the narrative hardens have more freedom to choose their path. Those who wait tend to inherit constraints set by the market, clients, or acquirers.

AI is already changing how influence is created and rewarded. What remains undecided is how agency leaders respond to that reality.

The next phase of the industry will not be defined by who adopts the most tools, but by who is willing to rethink their model, challenge their assumptions, and make deliberate choices about the future they want to build, and who they want alongside them as they do so.
