6 Best ROI Growth Agency Alternatives for AEO in 2026

Direct Answer

If ROI Growth Agency's AEO (Answer Engine Optimisation) case study impressed you, but you want a team that runs AEO as the whole job, six alternatives are worth a look: Intelligent Resourcing, Omnius, Omniscient Digital, Siege Media, First Page Sage, and Position Digital. Every one of them treats AEO, or the closely related GEO (Generative Engine Optimisation), as a core specialty. None treat it as a side result inside a broader growth agency. Which one fits depends on your industry, your budget, and how closely you want to work with the team.

Key Facts

• ROI Growth Agency is a full-service growth agency with a genuine AEO result. SEO (Search Engine Optimisation), paid media, and CRO (Conversion Rate Optimisation) are the core business. AEO is a newer, proven addition.
• Every alternative here runs AEO as its core specialty. None treat it as a side project to a bigger service list.
• Team size and access vary a lot. From Omnius's deliberate 8-clients-a-year cap to First Page Sage's enterprise, multi-vertical model.
• What predicts AI citation is category fit, not authority or team size. That single fact matters more than which name is biggest on this list.
• Intelligent Resourcing is one option among six, built around answering that category-fit question directly rather than through one case study.

Where ROI Growth Agency's Model Runs Out

ROI Growth Agency's FAQ case study is real. One page, cited in Google's AI Overview within 48 hours, is a specific and checkable result. The limit shows up in what that one result can prove. It shows the format works once. It doesn't show whether the same approach holds up across every question a buyer actually asks before deciding, in every category ROI Growth Agency's clients operate in.

The agency is candid about this itself. Its own expertise page says AEO citation reporting is newer than its SEO track record, and that results take three to six months to show measurably. One page moved in 48 hours. The programme is planned in months.

That gap is exactly where dedicated AEO agencies compete. Each one below has built a business around answering it, some through boutique focus, some through published research, some through raw team scale.

How to Evaluate Any AEO-Specialist Agency

Before comparing names, a few questions cut through the marketing:

• Does the agency publish its own research or a named methodology, or just claim expertise? A testable approach beats a service description.
• What's the actual client cap or team size? A boutique agency capping at a handful of clients a year works differently from a 100-plus person team running many accounts at once.
• Does it measure citation specifically, not just traffic or rankings? AEO-specific reporting should look different from a standard SEO report.
• Is pricing public, or a "contact us" black box? Some agencies in this space publish real minimums. Others don't.

At a Glance

Boutique Partners Built for Speed

Two agencies on this list stay deliberately small, and both treat that as a feature rather than a limitation.

Omnius is a London agency founded by Mat Golubovic and Ana Pantic, with extra offices in Dubai and Belgrade. It works only with SaaS, fintech, and AI companies, and caps at 8 clients a year on purpose, to keep every engagement deeply integrated.

It also built its own AI visibility platform, to track AI and Google visibility from one dataset rather than stitching together third-party reports.

• Caps new clients at around 8 a year, on purpose, for deep integration
• Built and owns its own AI search visibility platform rather than relying on a third-party tool
• Focused only on SaaS, fintech, and AI companies, with offices in London, Dubai, and Belgrade

Position Digital is a London agency founded by Sean Begg Flint, working with early-stage B2B SaaS companies. One client, a MarTech company, saw AI citations increase by 221% after working with the agency. Another saw organic traffic grow 500% in three months.

• Small, founder-led team suited to early-stage startups
• Published result: a 221% increase in AI citations for one MarTech client
• Published result: 500% organic traffic growth within three months for another client
• Starts every engagement by measuring current AI visibility before building a plan

Both fit a buyer who wants a founder-close relationship over an enterprise engagement, with the trade-off that neither can take on unlimited clients at once.

Citation Engineering Through Authority

Omniscient Digital takes a different route entirely. Its 30-plus person team builds AI citation through entity authority. That means strong brand and author signals, backed by backlinks and thought-leadership placements AI systems can trace back to a credible source. Engagements start at $10,000 a month for full-service work.

• 30-plus person team, larger than most boutique AEO specialists on this list
• Named client work including Jasper, SAP, Asana, and Loom
• Citation engineering through entity building and backlink placement, not just on-page content
• Published starting price: $10,000 a month for full-service work

This approach compounds more slowly than a single well-structured FAQ page, since authority-building takes time. It's built for a company with a real story to tell. The goal is to become the source AI systems point to, not just one page that answers one question well.

Enterprise-Scale and Research-Backed Options

Two agencies on this list serve the largest buyers, and each backs its work with a public track record.

Siege Media reports $148.6 million a year in client traffic value, for clients including Airbnb, Zendesk, Asana, and Zapier. Note what that figure measures: estimated traffic value, not client revenue. Its style is highly readable, visually structured content, built for human readers before AEO even existed. That same structure has translated directly into AI citation strength.

• Reports $148.6 million a year in client traffic value across named enterprise clients
• 100-plus person team, one of the largest on this list
• Editorial design built for both human readers and AI extraction
• Digital PR and placement work to get featured on the roundups AI models already trust

First Page Sage was founded in 2009 as a B2B lead generation and SEO agency. Its founder, Evan Bailyn, later pioneered the agency's own GEO methodology. It now runs a named authority content architecture programme for clients including Microsoft, Salesforce, and Verisign.

• Founded 2009, with 15-plus years of SEO experience behind its AEO work
• Named enterprise clients including Microsoft, Salesforce, and Verisign
• Maintains an archive of original research, a rare public, checkable track record in this space
• Named methodology, not a vague service description

Both suit a larger brand with the budget and patience for a longer, research-backed build, rather than a quick single-page win.

Verdict

None of these six run AEO as a side offer. Each treats it as the main event. That's the real difference between them and ROI Growth Agency's model of SEO and paid media with one strong AEO case study on top.

The right pick isn't whichever agency has the biggest name. It's whichever one matches your industry, your budget, and the category-fit problem underneath your specific gap. A SaaS startup on a lean budget and an enterprise professional services firm need different builds, and different agencies on this list are built for each.

Where Intelligent Resourcing Fits

Intelligent Resourcing approaches the category-fit question directly rather than through a single case study.

Its Content Strategy service, including GEO, works from one content plan that drives the keyword research, the writing, and the schema work together, mapped to a defined buyer's actual questions across the categories that buyer cares about.

That's a different starting point than proving one page can get cited. It's built for a team whose AEO work needs to repeat across every category their buyers ask about, not rest on a single strong result. The trade-off: team size and delivery details aren't published in the same depth some competitors on this list disclose.

What Happens to Existing Work When You Switch

None of this means abandoning what ROI Growth Agency, or any current vendor, has already built. SEO foundations, published content, and existing domain authority don't disappear when you switch to an AEO specialist.

Keyword research and content already published can inform which buyer questions a new AEO programme should prioritise first. If the difference between AEO, GEO, and adjacent terms is still unclear, our AEO, GEO, and LLMO explained breakdown covers where they overlap and where they don't. A specialist agency builds on that foundation rather than starting from zero, especially where existing content already ranks well and just needs restructuring for AI extraction.

The moment to switch is when AEO needs to become the main event, not a side project. There's no rush if one strong case study is enough proof for your situation. If you need that result to repeat consistently across every category your buyers actually ask about, that's the case for a specialist over a generalist with one good example.
