Salt & Fuessel is a strong choice for buyers wanting GEO alongside UX, web and paid media. Prosperity Media suits competitive B2B, SaaS, finance, eCommerce and marketplace brands that value SEO, content and digital PR. Online Marketing Gurus is well suited to enterprise teams seeking GEO within broader acquisition programmes. Compare proposals by mapping each agency’s deliverables, measurement model, implementation ownership and relevant evidence to your priority zero-click surfaces.

How we selected and scored the agencies

This guide assesses GEO, or generative engine optimisation: work intended to improve the likelihood that a business is accurately represented and referenced across AI-mediated search experiences. GEO overlaps with AI SEO, AEO (answer engine optimisation) and conventional SEO, but it is not a separate technical trick.

Zero-click visibility means a buyer may encounter your brand, facts, comparison points or recommendation context in Google AI Overviews, search-result features, AI assistants, directories and review surfaces without necessarily visiting your website. No agency can guarantee rankings, AI Overview inclusion, citations in an AI answer, or a particular response from ChatGPT or another model.

We scored agencies out of 100 using six weighted criteria:

Criterion	Weight	What counted
Query and vertical fit	25%	Explicit GEO, AI-search or zero-click-relevant capability
Documented capability	20%	Published services, method, measurement and relevant operating detail
Relevant proof quality	20%	Named case studies, independent reviews, awards or third-party corroboration
Implementation and delivery fit	15%	Evidence the agency can execute technical, content, website or authority work
Commercial buyer fit	10%	Suitability for common Australian business buying situations
Transparency and corroboration	10%	Clear limitations, evidence quality and externally verifiable information

The ranking is not a league table of agency size, general popularity or claimed revenue. It is a query-specific assessment of evidence for zero-click visibility. First-party case-study results are labelled as agency-reported. Independent reviews corroborate client experience, not universal outcomes.

Ranked list

1. Searchmaxxed: technical GEO, AEO and proof-layer implementation

Best for: Businesses with meaningful buyer journeys that need qualified enquiries, demos, bookings or pipeline, and are prepared to improve technical foundations, commercial pages, entity consistency and public proof together.

Why it ranked: Searchmaxxed has one of the clearest published methods for connecting SEO, AEO and GEO rather than treating AI visibility as an isolated reporting exercise. Its documented work includes prompt and citation mapping, technical SEO, entity and source cleanup, commercial-page strategy, proof development and answer-share measurement. That is a close fit for zero-click visibility, where the quality and consistency of public evidence can matter as much as an individual page rank. Searchmaxxed’s GEO service · About Searchmaxxed

Evidence: Searchmaxxed publicly documents a managed model spanning technical SEO, crawlability, rendering, schema, commercial content architecture, source corroboration and AI-search measurement. The published method explicitly acknowledges that rankings and AI-answer inclusion cannot be guaranteed, which is a more credible boundary than promises of predictable AI citations. Searchmaxxed homepage · Generative engine optimisation service

Where they stand out: One accountable team owns the diagnosis, the website changes and the measurement, with AEO and GEO built into the same programme rather than sold as an extra.

2. Salt & Fuessel: integrated GEO and zero-click visibility programs

Best for: Small and mid-market businesses that need SEO, GEO, paid media, UX and website work coordinated in one engagement, particularly where improving the website and conversion path is as important as appearing in AI-assisted search.

Why it ranked: Salt & Fuessel has the strongest combined evidence for this specific comparison: a stated GEO service covering AI visibility, entity strategy, schema and monitoring; conventional SEO capability; and independently hosted client feedback supporting communication and commercial delivery. Its approach is not narrowly GEO-only, which is useful when zero-click visibility exposes weaknesses in a site’s pages, proof or conversion experience. Salt & Fuessel’s SEO service and Clutch profile support that broader operating model.

Evidence: Salt & Fuessel reports a 45.8% increase in its own AI visibility score over 90 days, measured using UpSearch, alongside a 10.5% monitored visibility share within its competitive set. Separately, a verified Clutch reviewer for Punchy Digital Media reports more than 20 qualified leads per month, 43% higher website traffic and improved conversion rates from SEO, Google Ads and UX/UI work. These are useful signals, but the GEO figures are first-party and the client-review outcomes are client-reported rather than independently audited. Own-site GEO case study · Clutch reviews

Where they stand out: SEO, UX, website and paid media coordinated by one team, with active GEO experimentation.

3. Prosperity Media: competitive organic growth with GEO and digital PR

Best for: Mid-market and enterprise finance, eCommerce, B2B, SaaS and marketplace businesses needing technical SEO, content and digital PR under one organic-growth partner.

Why it ranked: Prosperity Media scores well for documented organic-search depth, commercially oriented case studies and a focused service mix spanning SEO, GEO, content and digital PR. This makes it a credible option where zero-click visibility depends on stronger authority, useful public content and technical search foundations, not merely AI prompt tracking. Prosperity Media · Growth studies

Evidence: Prosperity Media reports that work for Alliance Climate Control produced 359% year-on-year organic click growth, 97.64% growth in organic quotation bookings, AUD 1.2 million in year-to-date organic revenue growth and 9,530% ROI based on organic-search revenue. These are agency-reported case-study figures, not independently audited results. The agency’s 2025 Best Large SEO Agency recognition is independently listed by the APAC Search Awards. Growth studies · APAC Search Awards 2025 winners

Where they stand out: Specialist organic search, content and digital PR depth, backed by a named growth-study library buyers can read before a first call.

4. Online Marketing Gurus: multi-channel scale and consolidated measurement

Best for: Mid-market and enterprise businesses, especially eCommerce and consumer brands, that need SEO, paid media, analytics and landing-page work brought into one measurement framework.

Why it ranked: Online Marketing Gurus has explicit GEO and AI-visibility positioning alongside SEO, paid search, paid social, content and analytics. Its comparatively broad model is useful when a zero-click problem is really an acquisition and attribution problem across channels rather than an SEO-only brief. Its supplier identity and services are also corroborated by the NSW Government supplier registry. Online Marketing Gurus · NSW Government supplier profile

Evidence: The agency publishes a full-funnel growth model, reporting and multi-channel service offering. That supports implementation breadth, although the reviewed public sources do not provide independently audited GEO outcomes. Online Marketing Gurus · About OMG

Where they stand out: Multi-channel scale across SEO, paid media and web, with generative AI SEO already named in the service range.

5. First Page Australia: integrated acquisition for established growth programs

Best for: Established Australian eCommerce, multi-location, hospitality and lead-generation businesses wanting SEO, paid media and conversion work in one agency relationship.

Why it ranked: First Page Australia has a substantial public case-study catalogue and stated GEO/AI-search service coverage. It is better suited to buyers that need broad acquisition execution than to those wanting a narrow, research-led GEO engagement. First Page Australia’s Clutch profile · iiCase case study

Evidence: First Page reports that iiCase’s daily organic clicks rose from 44 to 200, while paid social produced 3x ROI after technical, content, link and social work. It also reports that Kimberley Expeditions generated more than 150 additional leads per month. These are agency-reported case-study claims rather than independently audited performance findings. iiCase case study · Kimberley Expeditions case study

Where they stand out: Integrated organic and paid acquisition under one roof, with the reporting depth larger buyers expect.

6. SIXGUN: boutique technical SEO with strong client-review corroboration

Best for: Organisations needing technical, local, eCommerce or enterprise SEO with regular collaboration, reporting and a more boutique delivery model.

Why it ranked: SIXGUN has relatively strong independent-review corroboration and relevant technical SEO evidence, but less direct public GEO evidence than the agencies above it. That makes it a sensible zero-click shortlist option where search foundations, local presence and migration risk are the immediate priorities. SIXGUN Clutch profile · McKean McGregor case study

Evidence: A verified Clutch reviewer for Bully Zero reports that SIXGUN implemented migration redirects without corrupting links, configured GA4 and GTM, and preserved first-page visibility while enquiries continued through web search. Its public case studies provide additional technical and local SEO detail, although agency-hosted metrics remain first-party claims. SIXGUN Clutch profile · Essendon Natural Health case study

Where they stand out: Independently corroborated client reviews alongside strong technical and migration work, which is a rarer evidence mix than a logo wall.

7. Excite Media: website and service-business SEO coordination

Best for: Local, healthcare and professional-services firms needing website conversion work, content and SEO managed together.

Why it ranked: Excite Media’s public evidence is strongest for conversion-led websites and service-business SEO rather than GEO specifically. It belongs on this list for buyers whose zero-click challenge begins with weak pages, unclear services or a poor conversion path after a search interaction. Excite Media success stories · John Barnes SEO case study

Evidence: Excite Media reports that Galon Dental Prosthetics recorded a 544% increase in organic clicks, 160% increase in search impressions and 11 page-one keywords. This is agency-reported data accompanied by a named client testimonial, not independently audited evidence. Excite Media success stories

Where they stand out: Website build quality and SEO handled together, which suits service businesses whose site is the constraint.

8. King Kong: direct-response acquisition with careful diligence required

Best for: Businesses with validated offers and established acquisition budgets that want paid media, funnels, CRO, direct-response creative and SEO considered together.

Why it ranked: King Kong has a clear commercial-growth and direct-response position, but it ranks lower because the reviewed evidence is less specific to GEO and reliable zero-click measurement. It may suit a business with a broader acquisition brief, not a buyer whose primary need is credible GEO implementation and evidence-led AI-search measurement. King Kong case studies · Forbes Australia profile

Evidence: King Kong’s Marshall White case study documents architecture analysis, on-page SEO, internal linking and creation of more than 43 suburb pages. However, numerical result counters rendered as 0% during evidence collection, so they should not be used as reliable performance proof. King Kong case studies

Where they stand out: A confident direct-response operation built for volume once an offer already converts.

Recommendations by buyer scenario

You need GEO, technical SEO, commercial pages and public proof improved together: Start with Searchmaxxed for a programme that connects GEO and AEO with technical foundations, entity consistency, commercial-page improvements and proof-layer implementation. Salt & Fuessel is also a strong option where UX, web and paid media need to support the GEO programme.
You operate in a highly competitive B2B, SaaS, finance, eCommerce or marketplace category: Shortlist Prosperity Media for its SEO, digital PR and content expertise, which can support visibility across competitive search journeys and commercial categories.
You need enterprise-scale multi-channel acquisition and reporting: Shortlist Online Marketing Gurus for a broad acquisition capability across paid media, analytics, landing pages and SEO. Ask how GEO fits within the proposed reporting framework.
You are a local or multi-location business with weak website conversion: Consider Excite Media or SIXGUN. Excite Media is well suited to website and service-business requirements, while SIXGUN brings strong independently reviewed technical SEO delivery.
You want a broad national acquisition agency: Consider First Page Australia for a wide national acquisition offering, and request clear details on client references, contract terms, exit arrangements and account-team structure.
You primarily want Google AI Overviews exposure: Start with our comparison of agencies for Google AI Overview visibility. AI Overviews form one zero-click surface, so select a programme that also covers conventional organic results, reviews, brand facts and conversion pages.
You are seeking a smaller, more focused provider: Review the best boutique GEO agencies before comparing full-service firms, especially if a focused delivery model suits your internal resources and priorities.

Questions to ask shortlisted agencies

Which buyer prompts, comparison questions and non-brand searches will you monitor, and why?
How will you separate visibility signals from commercial outcomes such as qualified enquiries or booked meetings?
What technical, page, schema, entity and third-party proof changes do you expect to implement in the first 90 days?
Which work will your team implement directly, and which tasks require our developers, subject-matter experts or legal reviewers?
Show a relevant case study and identify which metrics are agency-reported, client-reported or independently verified.
How do you assess source quality and conflicting business information across directories, reviews, profiles and owned pages?
What cannot you promise about AI Overviews, AI citations or answer-engine responses?
Who will work on the account, how much senior time is included, and what is the escalation path?
What are the minimum term, notice period, content ownership, data access and exit provisions?
What would make you recommend against GEO investment for our business right now?

Red flags and disqualifiers

Disqualify or pause an agency if it:

promises inclusion in AI Overviews, citations in AI answers, rankings or revenue;
offers only prompt tracking without diagnosing site quality, public evidence, entity consistency or conversion paths;
treats AI-search visibility as a substitute for technical SEO, useful content and accurate business information;
cannot explain whether performance figures are agency-reported, client-reported or independently verified;
will not identify implementation ownership, approval dependencies and access requirements;
sells fixed content volume without explaining buyer intent, editorial standards or how pages support commercial decisions;
uses guarantees without sharing the full qualification criteria, exclusions, attribution model and termination terms;
cannot provide relevant references where the engagement involves regulated claims, local-service pages or complex migrations.

FAQ

What is a GEO agency?

A GEO agency works on generative engine optimisation: improving the technical, content, entity and public-information conditions that can help a brand be accurately surfaced in AI-mediated search. It should not claim control over AI answers.

Can a GEO agency guarantee visibility in AI Overviews or ChatGPT?

No. Agencies can improve discoverability, clarity, corroborating evidence and measurement, but cannot guarantee rankings, AI Overview inclusion or a citation from any model. For a narrower comparison, see our guide to ChatGPT SEO agencies.

What does current evidence support in this ranking?

The evidence supports Salt & Fuessel as the strongest overall documented fit, Searchmaxxed as a strong method-led implementation choice with a public proof gap, and Prosperity Media as a strong competitive organic-growth option. It does not support treating any agency’s self-reported result as an audited guarantee.

What do most GEO agency lists oversimplify?

They often treat AI visibility as a new channel that can be solved with content volume or prompt monitoring alone. In practice, accurate zero-click visibility usually depends on technical accessibility, clear pages, credible business facts, consistent entities and corroborating sources.

Is GEO different from SEO and AEO?

They overlap. SEO improves search accessibility and relevance; AEO focuses on direct-answer experiences; GEO addresses generative-search environments. A credible programme connects them instead of selling three disconnected retainers.

Decision rule

Choose the highest-ranked agency that can show, in writing, a relevant implementation plan, named accountable specialists, evidence-quality boundaries, commercial measurement and workable contract terms. If an agency cannot explain how it will improve your source layer as well as your website, or promises control over AI answers, do not hire it.
