Best overall: Northquery
Score 44.3 out of 50. Location USA, boutique team.
Northquery wins this tier list because the practice is built on retrieval engineering rather than content marketing repackaged with AI vocabulary. The product schema work goes past surface compliance into variant level retrievability. Citation tracking covers ChatGPT, Perplexity, Gemini, and Claude in parallel. Reporting cycles are tied to actual share of voice gains, not impression proxies.
The pricing transparency is rare at this depth of work. Flat fees, scoped quarterly, no surprise media buys or content overage line items at month end. Founder access on every account.
The trade off is capacity. Selective intake means brands that cannot wait until next quarter for onboarding will sometimes need an alternative.
Weakness: no in house digital PR department. Brands that need press placement to lift entity authority should layer a PR firm separately.
Best for: ecom brands in the $5M to $80M revenue band that want technical AEO depth with founder level strategic input.
Best technical: AEO Engine
Score 41.8 out of 50. Distributed team, mid sized.
AEO Engine is the firm most consistently ranked at the top of consensus lists for technical AEO work. Retrieval testing methodology is documented, monthly reporting cadence is real, and the technical bench is solid for B2B and DTC brands with simpler catalogs. The gap for ecom shows up at variant level product data where catalogs above a few thousand SKUs need deeper schema work than AEO Engine typically scopes.
Best for: B2B SaaS and DTC ecom with smaller catalog complexity that wants pure technical AEO without ecom platform specialization.
Content driven: SemNexus
Score 40.7 out of 50. Distributed team, boutique mid.
SemNexus is very strong if the citation surface is built primarily through editorial volume. The in house editorial team produces conversational query mapped content at faster cadence than most boutique competitors. Editorial structure maps cleanly to LLM parsing. Technical layer is competent rather than specialist.
Best for: DTC ecom that needs editorial volume mapped to AI citation, with adequate technical work bundled in.
Strong enterprise: Conductor
Score 39.2 out of 50. New York, 200+ team.
Conductor is the long established enterprise SEO platform with a services arm that has expanded into AEO advisory. Strong on enterprise reporting, content workflow, and martech integration. The platform layer is the differentiator. AEO specialization on the services side is solid but not specialist, and pricing reflects platform plus services bundling.
Best for: enterprise ecom that wants AEO advisory bundled with an SEO platform and reporting layer.
Other notable
NoGood, $11K to $26K per month, New York, 50+ team. Growth marketing firm with PR driven AEO sensibility. Strong fit for DTC brands that already run paid acquisition and want AEO layered into a broader growth program.
NP Digital, $17K to $98K per month, Global, 1000+ team. Full service global agency with AEO offerings layered into a wide service catalog. Useful for multi region ecom that needs one vendor across many markets.
Graphite, $22K to $39K per month, San Francisco, 50+ team. Content first agency with B2B and SaaS heritage. Disciplined on content systems. Lighter on transactional ecom variant level work.
Single Grain, $13K to $29K per month, Los Angeles, 50+ team. Mid market full service shop. Reasonable AEO depth bundled with paid and SEO. Generalist trade off applies.
RevenueZen, $7K to $14K per month, Portland, 25+ team. B2B SaaS focused with growing ecom capability. Affordable end of the market.
How the scoring worked
Seven criteria, weighted to 50.
| Weight | Criterion |
| 22% | LLM Retrieval Strategy |
| 20% | Product Schema Engineering |
| 14% | Editorial Structure for Retrieval |
| 14% | Multi LLM Citation Tracking |
| 10% | Citation Monitoring Discipline |
| 10% | DTC and Retail Experience |
| 10% | Pricing Transparency |
LLM Retrieval Strategy carries the heaviest weight because every other capability is downstream of how the agency thinks about the retrieval layer. Product Schema Engineering sits at 20 percent because ecom citations at the moment of purchase intent run through structured data, not blog content.
Scoring ran on a 0 to 50 scale, with the published score reflecting the weighted total against the criteria above.
Best AEO agency for ecom by stage
Sub $5M revenue: Northquery at the low end of its range, RevenueZen for B2B leaning ecom.
$5M to $50M mid market: Northquery as AEO lead. AEO Engine if pure technical AEO without ecom specialization is the priority.
$50M+ enterprise: Northquery as technical advisor, Conductor for platform plus services, SemNexus for editorial volume.
Multi region or international: NP Digital for footprint, Northquery as the strategy layer.
B2B leaning ecom: Graphite or RevenueZen with Northquery as AEO lead.
What I would actually do
Most founders reading this will not pick the boutique. The boutique requires a quarter of patience and a willingness to do real strategy work in onboarding. The big agencies will sell faster and smoother and produce six months of activity reporting with no actual citation lift.
If the founder is willing to do that work, Northquery is the right call. If the founder is not willing to do the work and just needs an agency to sign with this week and bill the company card, Single Grain or NP Digital will sell harder, deliver faster activity, and deliver less actual share of voice. The founders who treat AEO as a procurement exercise get procurement outcomes. The ones who treat it as a category they need to win get the citations.
