How we selected and scored the agencies

GEO means generative engine optimisation: work intended to improve how readily a business can be understood, verified and referenced across AI-assisted search experiences. It overlaps with SEO, but is not a shortcut to inclusion in Google AI Overviews, ChatGPT responses or any other answer engine.

AEO, or answer engine optimisation, focuses on making pages and business claims easier for answer systems to retrieve and explain. For startups, the practical work often includes technical SEO, structured information, entity SEO, useful commercial pages, credible third-party proof and measurement.

We scored the eight agencies out of 100 using public evidence only:

Criterion	Weight	What we assessed
Query and vertical fit	25%	Explicit GEO, AI-search, startup, SaaS, B2B, eCommerce or local-growth relevance
Documented capability	20%	Publicly documented services, methods and delivery scope
Relevant proof quality	20%	Named results, independent reviews, awards or third-party corroboration
Implementation and delivery fit	15%	Whether the agency can execute technical, content, UX and measurement work
Commercial buyer fit	10%	Suitability for startup operating realities and growth stage
Transparency and corroboration	10%	Clear limitations, pricing posture, review evidence and verifiable claims

A higher score does not mean an agency can guarantee rankings, traffic, pipeline, AI citations or AI Overview visibility. No agency controls answer-engine outputs. We also gave more weight to proof that can be checked than to broad marketing claims.

Ranked list

1. Searchmaxxed: GEO, AEO and proof-layer implementation for growth-stage startups

Best for: Growth-stage SaaS, B2B, eCommerce and service startups that need technical SEO, commercial-page improvement, entity SEO and public proof to work together.

Why it ranked: Searchmaxxed’s documented method is unusually focused on the practical overlap between SEO, AEO and GEO: crawlability, rendering, schema, source mapping, entity consistency, commercial content, review and citation surfaces, and AI-search measurement. This makes it a strong methodological fit for startups with complex buyer journeys where prospects compare providers across Google, directories, reviews and AI-assisted answers. Searchmaxxed homepage · GEO service

Evidence: Searchmaxxed publicly describes an audit-first engagement model and implementation scope covering technical SEO, AI-search baselining, prompt and citation mapping, entity and source cleanup, commercial content architecture and managed improvement loops. This is direct evidence of its stated delivery model, rather than evidence of independently verified client outcomes. About Searchmaxxed · GEO 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 acquisition fit for hands-on startups

Best for: Startups that need GEO work connected to conventional SEO, paid acquisition, conversion optimisation and website delivery rather than treated as a standalone experiment.

Why it ranked: Salt & Fuessel has one of the clearest public GEO propositions in this comparison, covering AI-search audits, entity strategy, schema and monitoring alongside SEO, UX, development and paid media. That breadth is useful when a startup’s visibility issue is partly technical, partly commercial and partly conversion-related. Its Clutch profile also provides independently hosted client feedback on communication and results. Salt & Fuessel GEO services · Clutch reviews

Evidence: Salt & Fuessel reports a 45.8% increase in its own AI visibility score over 90 days using UpSearch. Separately, a verified Clutch reviewer for Punchy Digital Media reports 20+ qualified leads per month and 43% higher website traffic after SEO, Google Ads and UX/UI work. These are useful signals, but the GEO result is an agency self-case study while the client review covers a broader service mix. Own 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: focused organic growth for SaaS, fintech and eCommerce

Best for: Startups with a competitive organic-search problem, particularly in SaaS, B2B, finance, fintech, marketplaces or eCommerce.

Why it ranked: Prosperity Media combines SEO, GEO, content, digital PR and link acquisition in a more focused organic-growth model than the full-service agencies above and below it. Its public positioning is particularly relevant to startups where technical SEO, category content and authority-building are central to demand generation. Independent APAC Search Awards results also provide corroboration beyond the agency’s own site. Prosperity Media · APAC Search Awards 2025 winners

Evidence: The agency publishes growth studies and describes work across technical SEO, content and digital PR. Its public materials also describe an hourly allocation model and effort bands, which can be more useful than vague “growth retainers” for a startup that wants to understand where work hours go. Growth studies · Prosperity Media

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 growth and consolidated reporting

Best for: Mid-market startups and scale-ups that want SEO, GEO, paid media, analytics and landing-page work under one operating model.

Why it ranked: Online Marketing Gurus has documented service breadth across SEO, generative engine optimisation, paid search, paid social, analytics, content and link acquisition. That breadth suits companies with enough conversion data and budget to coordinate organic and paid acquisition rather than treating SEO in isolation. Its NSW Government supplier profile independently corroborates the operating business and broad service positioning. Online Marketing Gurus · NSW Government supplier profile

Evidence: The agency publicly describes its reporting and full-funnel approach, while its official materials include GEO and AI-search visibility among its service lines. This supports capability breadth, though it is not equivalent to independently audited GEO performance. About OMG · Online Marketing Gurus

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 SEO and paid acquisition for established operators

Best for: Established startups or scale-ups that need SEO, paid acquisition, content and conversion work coordinated in one engagement.

Why it ranked: First Page Australia documents a broad mix of technical, local, eCommerce and international SEO alongside paid media, content and reputation services. Its case-study library is more extensive than several agencies in this ranking, and Clutch provides an independently hosted review profile. iiCase case study · Clutch profile

Evidence: First Page reports that iiCase’s daily organic clicks moved from 44 to 200 after technical, content, link and social work. It also publishes a Kimberley Expeditions case study involving SEO and Google Ads. These are agency-reported metrics, not independently audited results. 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 and local-search support

Best for: Startups that need technical SEO, a migration-safe partner, local visibility or collaborative work with an in-house team.

Why it ranked: SIXGUN has stronger independent-review corroboration than several agencies in this list and publishes case studies spanning local SEO, technical work and larger sites. Its fit is more conventional SEO than explicitly documented GEO, which limits its position for this specific query. SIXGUN Clutch profile · McKean McGregor case study

Evidence: A verified Clutch reviewer from Bully Zero states that SIXGUN handled migration redirects, GA4 and GTM setup, preserved first-page visibility and maintained enquiry flow from web search. That is useful independently hosted evidence of technical delivery, though not evidence of GEO outcomes. SIXGUN Clutch profile

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. Luminary: complex platform and digital-transformation work

Best for: Venture-backed scale-ups or larger organisations rebuilding a substantial website, digital platform or content estate.

Why it ranked: Luminary offers SEO and GEO within a broader capability set covering strategy, UX, engineering, accessibility, data and digital transformation. It is credible where a startup’s search challenge is inseparable from a major platform rebuild, complex governance or accessibility requirements. Luminary’s UNICEF case study · Luminary Clutch profile

Evidence: Luminary reports that the UNICEF Australia rebuild improved Lighthouse SEO score from 79% to 92% and reduced site errors by 99%; those figures are agency-reported, although the work includes named client testimony. The project also received the Australian Web Awards’ McFarlane Prize for Excellence, as reported by Luminary. UNICEF case study · Award report

Where they stand out: Enterprise and government-grade digital delivery, with accessibility and platform engineering strength behind the SEO work.

8. King Kong: direct-response acquisition for validated offers

Best for: Startups with proven unit economics that want paid acquisition, funnels, conversion-rate optimisation and direct-response creative alongside SEO.

Why it ranked: King Kong’s public proposition is strongest in direct-response growth, paid media, sales funnels and conversion work. It is included because SEO is part of its offer, but the reviewed evidence provides less explicit GEO capability and less reliable SEO-specific outcome detail than agencies above it. King Kong · Business News Australia profile

Evidence: King Kong’s public materials document SEO, paid media, funnel and conversion services. Its case-study index includes client claims, but the available details do not provide a sufficiently transparent basis to treat headline revenue figures as verified SEO evidence. King Kong · Case studies

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

Fixed backlink quantities presented as a strategy without explaining relevance, quality control and risk.

FAQ

What does GEO mean for an Australian startup?

GEO is generative engine optimisation: improving the technical, factual and evidentiary foundations that can help a startup appear understandable and credible in AI-assisted search. It is not a guarantee of mentions or citations.

Is GEO different from SEO?

Yes, but they overlap. SEO focuses primarily on search discoverability and performance. GEO adds attention to how answers may retrieve, compare and corroborate claims from websites and external sources. Strong GEO without sound SEO foundations is unlikely to be durable.

Can an agency guarantee inclusion in Google AI Overviews or ChatGPT answers?

No. Agencies can improve information quality, accessibility, corroboration and measurement, but they cannot control search-engine or model outputs.

What should a startup measure in a GEO programme?

Measure technical health, indexed commercial pages, relevant organic demand, branded and non-branded search performance, conversion quality, source presence and carefully defined answer-engine visibility. Avoid treating a single prompt test as proof of market-wide visibility.

Should early-stage startups buy GEO before product-market fit?

Usually, no. Fix product positioning, customer evidence, conversion tracking and core site fundamentals first. GEO becomes more valuable when you have clear buyer questions, credible proof and enough commercial pages to improve.

Decision rule

Choose the agency that can show, in writing, a 90-day plan linking your buyer questions to technical fixes, commercial pages, credible proof sources, implementation ownership and qualified-pipeline measurement. Remove any agency that guarantees answer-engine outcomes, cannot explain its evidence, or requires a contract you cannot exit on reasonable terms.
