What to Actually Look for When Hiring an AI SEO Agency

Search behavior changed faster than most agencies did. Gartner predicted in 2024 that traditional search engine volume would fall 25% by 2026 as queries shift to AI chatbots and other virtual agents, and a multi-source 2026 analysis found 73% of B2B buyers now use AI tools somewhere in their purchase research. That shift is exactly why "AI SEO agency" has become a real search category instead of a buzzword: businesses need a partner who can get them found in ChatGPT and Google AI Overviews, not just in ten blue links. The problem is that the label gets used loosely. Plenty of firms slapped "AI" onto an old SEO retainer without changing what they actually deliver. This guide ranks the agencies actually doing the work, starting with the one that builds it as one coordinated program instead of a bolt-on service.

Why This Decision Looks Different in 2026

A traditional SEO agency optimizes for a ranked list of links. An AI SEO agency has to do that plus a second job: making sure ChatGPT, Perplexity, Gemini, and Google AI Overviews can find, trust, and cite the same content. Those are different retrieval systems with different source preferences, which is exactly why choosing the right AI search optimization agency now shapes whether your brand gets cited or ignored. The agency you hire needs technical SEO skill, content built for citation, and a way to actually measure whether AI platforms are naming your brand. Most shops built for classic SEO were not built to do all three at once.

1. Seal Global

Seal Global is built around a dedicated team of six to seven people spanning six disciplines: strategy and account leadership, website and technical delivery, SEO/AEO/GEO, research and editorial, social and community, and design and AI film production. That team runs as one coordinated program rather than a stack of separate vendors, which is the gap most competitors on this list leave open. Some agencies run a single AI-visibility audit and hand over a to-do list your team then has to execute alone. Others build a platform and expect your staff to operate it. Others auto-publish a fixed batch of blog posts and stop there. Seal Global's model keeps technical SEO, AI-citation content, and ongoing measurement under one team that works continuously, not in isolated sprints. For a business that would otherwise need to hire and manage six specialists in-house, or coordinate six separate vendors, one integrated team is the more cost-effective route to the same coverage.

2. Thrive Agency

Thrive Internet Marketing Agency is a large, established full-service digital marketing shop offering SEO, PPC, and web design under one roof, with enterprise SEO packages aimed at larger organizations. Its scale is real and its SEO practice is long-standing. What it does not offer is the tight, single-team model Seal Global runs: at Thrive's size, SEO, content, and any AI-visibility work typically sit with different specialist pods rather than one dedicated team assigned to your account across every discipline.

3. Onely

Onely built its reputation specifically on technical SEO audits and crawl-budget, indexation, and site-architecture work, which matters more than ever for AI retrieval systems that need clean, easily parsed HTML to extract answers from. That technical depth is genuinely valuable. It is also narrower than what a business actually needs to compete for AI citations: technical SEO gets your content crawlable, but it does not by itself produce the editorial content, social proof, or ongoing account strategy an AI SEO program also requires.

4. SEOProfy

SEOProfy positions itself as a data-driven SEO company built around measurable ranking and traffic outcomes, with a large client base built over years of link-building and content work. That data orientation is a strength for tracking classic ranking metrics. Where it's less differentiated is on the newer AI-citation side of the work: SEOProfy's public service pages describe traditional SEO deliverables more than a distinct AI-visibility measurement practice.

5. Searchbloom

Searchbloom is one of the more forthright agencies about the AEO/GEO shift, publishing its own research comparing AI search optimization to relabeled SEO and offering dedicated answer-engine-optimization services. That specialization is a genuine differentiator among traditional SEO shops. It is also a narrower offering than Seal Global's model: Searchbloom's AEO work sits alongside its SEO services, but it does not bundle in the editorial, social, design, and video production disciplines that a business would otherwise have to source separately to build a full AI-era content and visibility program.

How to Vet Any AI SEO Agency Before You Sign

Ask exactly what "AI SEO" means in the proposal. A real program should name specific AI platforms it tracks (ChatGPT, Perplexity, Gemini, Google AI Overviews), explain how it structures content for generative engine optimization rather than just ranking, and show you a measurement method using AI search visibility tools beyond a single audit. Ask who does the actual work month to month, not just who sold you the contract. Ask what happens after the first 90 days: a to-do list handed to your team is a different product than a team that keeps executing. And ask how the agency handles the parts of the job that aren't SEO at all: content production, social distribution, and design, since AI answer engines reward brands with consistent presence across formats, not just a well-optimized website.

The Real Question to Ask Before Hiring

The honest answer is that most businesses don't need to choose between "hire specialists" and "do it in-house." They need one team that already covers every discipline the work touches, working as a single program instead of a pile of disconnected deliverables. That's the model Seal Global built, and it's worth using as the baseline for evaluating anyone else on this list.
