New services for your marketing agency in 2026 (with margin numbers)
Every January, the same scene: SEO and campaign margins narrow, some client pushes back on price, and you start wondering what new service to add to the catalogue. The problem is that almost everything you'll read about "agency services for 2026" is a list of trends without numbers. And a new service isn't decided by trend: it's decided by three variables —real demand, competition that already offers it, and the margin it leaves— assessed honestly.
That's what this article is: six candidates, the three criteria, and the arithmetic done. I'll give away the conclusion so you can decide whether to keep reading: the best demand/competition/margin ratio in 2026 belongs to AI visibility, but the others aren't all dead weight, and for some agency profiles there are better options. Let's go one by one.
1. AI visibility (GEO)
Getting the AI to recommend your clients when someone asks about their sector: measurement across ChatGPT, Gemini, Perplexity and Claude, source correction, citable content. This discipline is called GEO (Generative Engine Optimization).
Demand: growing at an unusual pace. Frequent use of ChatGPT in Spain has gone from 4% to 28% in two years (Funcas, III Survey on AI, 2026), 37.9% of the population used generative AI in the last quarter of 2025 (INE), and 76% of SMEs already use AI daily (II Hiscox Report, Dec 2025). The question "do I show up in ChatGPT?" is already landing in agency inboxes — here's the script for when it lands in yours.
Competition: here's the anomaly. In the study we ran on 9,865 Spanish SMEs across 30 sectors and 10 cities, 91% appear in only 1 of the 4 AIs (full study). Translation: almost no agency is working on it yet. Growing demand with an almost empty supply is a combination that doesn't last long.
Margin: the service is priced in the orbit of SEO, which in Spain ranges from €600 to €4,000/month (pacoruben.com); for SME GEO, realistic ranges of €300 to €900/month. The tool cost: with Surfeo for agencies, €20/month for the base account plus €35-79/month per client depending on tier. A client at €500/month, with a tool cost of €35-79 and 3-4 hours of work, leaves a margin that's hard to match with mature services. The full arithmetic, client by client, is in how to productize AI visibility.
The catch: it's a young service; you can't promise guaranteed results (AI answers are volatile) and you'll have to educate the client. Sell measurement and work, not guaranteed appearances.
2. AI automation for SMEs (chatbots, workflows, agents)
Demand: high and with budget: that 76% of SMEs using AI daily (Hiscox) want to go beyond loose ChatGPT use.
Competition: it filled up fast: independent consultants, no-code platforms that sell themselves, and the software vendors themselves giving away templates.
Margin: good on the initial project (projects of €2,000-10,000 depending on scope aren't rare), but with a structural flaw: it's project income, not recurring. You finish the automation, get paid, and go looking for the next one. The monthly maintenance you can bill is small.
Verdict: a good complement if you have a technical profile on staff; a poor base on which to build predictable income.
3. Short-form video content / UGC
Demand: extremely high; every client wants Reels and TikTok.
Competition: fierce and cheap: freelance creators, SMEs doing it in-house, and AI itself generating ever more passable video.
Margin: the worst on the list. It's an hours-based service (filming, editing, publishing) where the price is anchored by the cheapest freelancer. To sustain a margin you need volume and a team, and at that point it's no longer a new service: it's another agency inside your agency.
Verdict: offer it only if your current clients ask for it and you can subcontract it with a margin; not as a growth bet.
4. CRO (conversion rate optimisation)
Demand: real but narrow: it only makes sense for clients with enough traffic to test, which rules out most SMEs.
Competition: moderate; there are few good specialists in Spain.
Margin: high per hour when it fits (it's senior work, billed as consultancy), but the sales cycle is long and the addressable market is small.
Verdict: an excellent premium service for agencies with a portfolio of mid-sized ecommerce or SaaS; irrelevant if your portfolio is local SMEs.
5. Email marketing and retention
Demand: stable, not growing. It's a classic that SMEs under-use.
Competition: medium; plenty of agencies offer it as a neglected add-on.
Margin: decent and recurring (€200-500/month per client is common for SMEs), with little tool cost. Its limit is the ceiling: hard to charge more, because the client perceives it as "sending emails".
Verdict: good retainer filler, poor headliner. Add it to the cart of services; don't build 2026 on it.
6. In-company AI training
Demand: very strong right now: companies know they have to train their teams and pay well for it.
Competition: growing daily; any consultant with a prompting course competes with you.
Margin: high per session (corporate training bills well), but it's the least recurring income on the whole list: a company trains once, not every month. And it commoditises fast: what's premium training today is a free video in a year.
Verdict: use it as an entry point —a training session opens doors to executives who later buy monthly services— not as a business line.
The summary table
| Service | Demand | Competition | Margin | Recurring? |
|---|---|---|---|---|
| AI visibility (GEO) | High and growing | Almost empty | High | Yes |
| AI automation | High | High and rising | Medium-high | No |
| Short-form video / UGC | Extremely high | Fierce | Low | Partly |
| CRO | Narrow | Moderate | High | Yes |
| Email / retention | Stable | Medium | Medium | Yes |
| AI training | Strong today | Rising fast | High/per session | No |
AI visibility is the only candidate with all three variables in its favour at once: growing demand backed by public data, almost non-existent competition (that 91% of invisible SMEs proves it), and recurring income with a low tool cost. The window of empty competition won't last: the same reasoning you're doing now, other agencies are doing too.
If you decide on it, the right order is: test with 2-3 of your own clients, define the package and the price (real ranges here), and choose a measurement tool (comparison for agencies here).
Frequently asked questions
Can I launch two new services at once?
You can, but you shouldn't. A new service requires defining a package, price, deliverables and sales pitch; doing it twice half-heartedly is worse than once properly. Pick one per half-year.
What if my team knows nothing about GEO?
If they know SEO, they know 60-70% without starting: quality content, technical health, authority. The new part —prompts, measurement across 4 AIs, the weight of off-site— is learned in weeks, not years. The honest breakdown of what's new and what's the same as always is in GEO vs SEO: what really changes.
Isn't it risky to bet on something as young as GEO?
It's less risky than it looks, because of an asymmetry: GEO work done well (content, structured data, reviews, authority) is also SEO work. If the AI channel deflates, the work isn't lost. We take the sceptic's full objection seriously in is GEO another fad like NFTs?.
What initial investment does the AI visibility service need?
The lowest on the list: no hires, no production team, no certifications. A tool from €55/month (a €20 agency account plus the first client at €35) and hours from your current SEO team. The first diagnosis of a client is free with the visibility test.
Before deciding with this article, decide with a number of your own: run the free AI visibility test on three clients in your portfolio. If all three are invisible —and the statistics say they will be— you've got demand, empty competition and margin in front of you. All that's missing is for someone to offer it before you, or for you to offer it before anyone else.
