How to differentiate your marketing agency in 2026: AI services almost nobody offers yet
Try it: open the websites of five agencies in your city, cover the logos and read the copy. "Bespoke strategies". "Measurable results". "Your digital partner". "A passionate team". If you can't guess which agency each line belongs to, the client can't either. And when the client can't tell providers apart, they decide on the only thing they can compare: price.
That's commoditisation, and it's the number one problem for agencies in 2026. I'm not telling you this to scare you: I'm telling you because there's a concrete way out, with a concrete time window, and this article is about how to use it.
There are only three ways to differentiate
Strip the filler from the positioning manuals and three strategies remain:
Be the cheapest. Works until someone cheaper shows up. It's a race to the bottom where the prize is working more for less, and where a freelancer with lower fixed costs than you can always win. Ruled out unless your model is pure volume.
Be the best. Legitimate, but slow and expensive to prove. "We're the best at SEO" is what they all say; proving it takes years of case studies, awards, personal brand. And even then, the average SME client can't tell excellent SEO from merely competent SEO until six months of invoices have gone by.
Be the only one. The most powerful and usually the most unreachable: almost everything you can offer is already offered by someone. Almost everything. Because there's a brief moment when a new discipline exists, has demand and still has no supply. Whoever enters then doesn't compete: they're the only one. That's how SEO was in 2005 and social ads in 2012. And that's how AI visibility is in 2026.
Why AI visibility is that window right now
AI visibility means that when someone asks ChatGPT, Gemini or Perplexity "which company for X would you recommend in Y?", the answer includes your client. The discipline that works on this is called GEO (Generative Engine Optimization). The name isn't what matters: it's the two numbers that define a window.
Demand: it exists and it's growing. Frequent ChatGPT use in Spain has gone from 4% to 28% in two years (Funcas, III AI Survey, 2026), and according to the INE 37.9% of the population used generative AI in the last quarter of 2025. The question "do I come up in ChatGPT?" is already landing in agency inboxes.
Supply: almost empty. In the study we ran on 9,865 Spanish SMEs across 30 sectors and 10 cities, 91% only appear in 1 of the 4 main AIs (full study). If agencies were working on this seriously, that number would be different. They aren't working on it.
Growing demand plus empty supply is the definition of "the only one". With one nuance that makes it reachable for a normal agency, with no need to be a visionary or to have an R&D team.
You don't need to be the only one in Spain: just the only one in your area or your niche
"The only one" sounds like wild ambition, but the SME client doesn't compare on a national scale: they compare among the three providers they know. If you're the only agency in your province — or the only one specialised in clinics, in hotels, in manufacturers — that measures and works on AI visibility with data, then for your market you're the only one. Full stop.
And the choice of niche isn't decorative: the same study shows invisibility varies enormously by sector (1 in 4 hotels appears in several AIs; in garages, 1 in 50). Pick the niche where you already have clients, audit ten companies and you'll have a commercial argument no competitor in your area can replicate this week.
The compulsory honesty: this window closes. The reasoning you're doing now, others will do too, just as everyone ended up offering SEO in the end. The difference between being "the only one" for two years and for six months is when you start. If you want to weigh this bet against other catalogue options, you have the analysis of new services for 2026 with the numbers and the margin breakdown by service.
How to communicate it without sounding like every agency website
This is where most people waste the advantage. If you communicate your new differentiation with the same old language — "we're pioneers in artificial intelligence" — you sound exactly like the agencies that don't have it. Four rules:
1. Show, don't claim. The line "we measure your AI visibility" doesn't differentiate; the screenshot where ChatGPT recommends a prospect's competitor and not them does. Your best commercial asset isn't a piece of copy: it's the prospect's own audit, done before the first meeting. With Surfeo for agencies this even has a name: pitch workspaces, spaces to audit a prospect and show them where they appear (and where they don't) before signing anything.
2. Speak the client's language, not the sector's. "GEO", "LLMs", "generative engines": jargon that levels you down. "Do you come up when someone asks ChatGPT for a dentist in Málaga?": a question anyone understands and that no other agency website in your area is asking.
3. Use sourced numbers, not superlatives. "91% of Spanish SMEs are almost invisible in AIs" with a link to the study is worth more than ten "leaders in innovation". Verifiable data is the antidote to interchangeable copy.
4. Say what you don't do, too. Nothing differentiates more than honesty in a sector that over-promises: "we don't guarantee appearances, because nobody can; we guarantee weekly measurement and verifiable work". The client burned by SEO promises notices it instantly. If it gives you vertigo, there's a way to validate it before announcing it: try it first with a single client and go to market with a real case in hand.
Differentiation is a service, not a slogan
Last point, the important one: this isn't about adding "AI" to your website. It's about adding a real service — measurement, source correction, citable content, monthly report — that your competitors don't offer. The slogan without the service gets exposed in the first meeting; the service without the slogan gets discovered on its own, because clients talk. Build the capability first, communicate it afterwards with the four rules above, and for as long as the window lasts you won't have to compete on price again.
Frequently asked questions
Does no agency really offer this yet?
Some are starting, mostly in Madrid and Barcelona and on large accounts. But the data rules: if 91% of SMEs only appear in 1 of 4 AIs, the effective supply for SMEs and local businesses is close to nil. Your relevant competition isn't "some agency in Spain": it's the three agencies you win or lose proposals against every month.
What if my agency is small and I can't invest in something new?
This is one of the few forms of differentiation that doesn't demand serious investment: no hires, no certifications, no production team. If your team knows SEO, they already know 60-70% of the discipline; the rest is methodology and a measurement tool. The barrier to entry is low — all the more reason to get in before everyone else does.
Isn't it risky to position myself on something so new?
The real risk is smaller than it looks, thanks to an asymmetry: AI visibility work done well (quality content, structured data, reviews, authority) is also SEO work that survives any scenario. If the channel deflates, you haven't thrown the work away. And you don't position the whole agency on it: you add it as a commercial spearhead while keeping the rest of your catalogue.
How long will the "be the only one" window last?
Nobody knows exactly, and be wary of anyone who gives you a date. What we do know: new-category windows in marketing have historically lasted between two and five years before saturating, and this one has adoption data growing faster than the previous ones. The practical question isn't how long it will last, but how many months of head start you want over your local competition.
