How we selected and scored the agencies

“Online platforms” can include eCommerce stores, marketplaces, SaaS products, directory businesses, multi-location operators and service businesses with complex buyer journeys. These businesses usually need more than blog production: they need crawlable architecture, useful commercial pages, technical implementation, demand-led content, credible off-site signals and conversion measurement.

We scored agencies against six weighted criteria:

Criterion	Weight	What we looked for
Query and vertical fit	25%	Evidence of work relevant to platforms, eCommerce, SaaS, marketplaces, complex websites or multi-location operations
Documented capability	20%	Technical SEO, content, authority building, migration, local or international capability, and AI-search capability where relevant
Relevant proof quality	20%	Named case studies, transparent methodology, independent reviews, awards or third-party corroboration
Implementation and delivery fit	15%	Whether the agency appears able to implement, not merely advise on, technical, content and conversion work
Commercial buyer fit	10%	Suitability for platform maturity, collaboration requirements, operating model and acquisition goals
Transparency and corroboration	10%	Clarity around scope, limitations, pricing posture, review evidence and independent validation

The ranking is not a measurement of total agency size, brand awareness or review volume. First-party case studies can be useful, but they are not independently audited unless stated otherwise. We also did not award points for claims we could not corroborate from the supplied public sources.

Evidence boundary: SEO can improve eligibility and competitiveness in organic search; it cannot guarantee rankings, traffic, leads or revenue. AEO, or answer engine optimisation, means improving the clarity and retrievability of information for answer-oriented search experiences. GEO, or generative engine optimisation, is the related practice of improving how a brand’s information may be understood and cited in generative search systems. Neither discipline can guarantee inclusion in Google AI Overviews or citations in ChatGPT or other large language model outputs.

Ranked list

1. Searchmaxxed: technical SEO, AEO and GEO implementation

Best for: Online platforms that need technical SEO, commercial-page improvements, entity consistency and AI-search measurement integrated into one implementation programme.

Why it ranked: Searchmaxxed has a distinctive public methodology for joining technical SEO with AEO and GEO. AEO concerns making information easier for answer engines to retrieve and present; GEO applies similar principles to generative search surfaces. The approach includes crawlability, rendering, indexation, schema, architecture, commercial content, internal linking, public proof and AI-search visibility measurement. Searchmaxxed’s homepage and about page document that scope.

Evidence: The public offer is explicit that AI-search work relies on source clarity, corroboration and observable measurement rather than promises of AI citations. This makes it a credible fit for buyers evaluating AEO agencies, AI SEO agencies or Google organic SEO as one system. Searchmaxxed’s pricing page explains its diagnostic-led, custom-scope approach.

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. StudioHawk: enterprise SEO, eCommerce and migration fit

Best for: Mid-market and enterprise online platforms that need a dedicated SEO partner for complex eCommerce structures, site migrations, technical remediation or international organic growth.

Why it ranked: StudioHawk’s narrow SEO positioning, stated direct-specialist model and no-long-lock-in stance are commercially useful for platform teams that already have internal developers, content resources or paid-media partners. Its public service material covers technical SEO, content, link acquisition, local, international, eCommerce, migrations and AI-search visibility. StudioHawk also has independently corroborated recognition in the 2026 APAC Search Awards.

Evidence: The agency publishes a consultant offering that describes direct access to SEO specialists and no long-term contracts, which is relevant for teams wanting practitioner involvement rather than a purely account-managed relationship. StudioHawk’s SEO consultant page is the supporting public source.

Where they stand out: SEO-only specialists with direct practitioner access, a no-long-term-lock-in posture and genuine migration and technical strength.

3. Prosperity Media: competitive organic growth for marketplaces and SaaS

Best for: Established marketplaces, SaaS businesses, finance brands, B2B companies and eCommerce operators facing competitive organic-search markets.

Why it ranked: Prosperity Media’s public positioning is unusually aligned with technically demanding platform work: SEO, generative search, content, digital PR and link acquisition, with stated experience across finance, international SEO, eCommerce, B2B, SaaS and marketplace SEO. Prosperity Media presents this as a specialist organic-growth offer rather than an all-channel marketing service.

Evidence: The agency has a public growth-study library and was listed in the 2025 APAC Search Awards winners, providing some independent corroboration beyond its own website. Its growth studies give buyers a starting point for reviewing relevant client examples and commercial framing.

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. First Page Australia: integrated SEO and paid acquisition

Best for: Established eCommerce, travel, hospitality, multi-location and lead-generation businesses that want SEO and paid acquisition coordinated under one agency.

Why it ranked: First Page Australia offers a broader channel mix than the two agencies above it, including SEO, paid search, paid social, content and reputation work. That breadth is useful when a platform’s organic strategy depends on landing-page testing, paid-search insight and conversion improvements rather than SEO alone. First Page Australia’s Clutch profile supports the agency’s broad public service mix.

Evidence: Its named iiCase case study shows the sort of intervention buyers should request: technical work, content, links and paid social tied to business metrics. First Page Australia reports daily organic clicks for iiCase rose from 44 to 200 and that paid social produced a 3x ROI; those are agency-reported figures, not independently audited results. Read the iiCase case study.

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

5. Online Marketing Gurus: multi-channel acquisition and reporting

Best for: Mid-market and enterprise eCommerce or consumer platforms that want SEO, paid media, analytics and landing-page work in one operating model.

Why it ranked: Online Marketing Gurus combines SEO and GEO with paid search, paid social, analytics, content, link acquisition and website work. That makes it more relevant where the buyer’s actual problem is cross-channel acquisition efficiency rather than organic visibility in isolation. Online Marketing Gurus describes this integrated approach, while its NSW Government supplier profile corroborates its operating identity and service positioning.

Evidence: The agency publicly presents a reporting-led performance model and serves businesses across multiple markets. For platform operators with fragmented channel reporting, that breadth can be commercially useful. About Online Marketing Gurus provides the relevant public overview.

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

6. Salt & Fuessel: SEO, UX and practical AI-search work

Best for: Small and mid-market online platforms that need website development, UX research, SEO and paid acquisition coordinated in a single engagement.

Why it ranked: Salt & Fuessel’s public material shows an integrated model spanning SEO, web development, conversion work, paid media and GEO. That is relevant when a platform’s organic problem is partly a usability, information architecture or conversion issue. Salt & Fuessel’s SEO service page outlines technical, content, local and reporting work.

Evidence: Its Clutch profile includes verified-review material describing outcomes from combined SEO, Google Ads and UX/UI work. The agency also publishes a GEO methodology and own-site experiment, though this should be viewed as a self-reported test rather than independent validation. Its AI visibility case study documents the approach and measurement context.

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

7. Excite Media: website-led SEO for service platforms

Best for: Local, healthcare and professional-services platforms that need a conversion-led website rebuild alongside SEO and content work.

Why it ranked: Excite Media’s evidence is particularly relevant for businesses where the website itself is suppressing organic conversion. Its public offer spans web design, development, SEO, local SEO, content, paid media and conversion optimisation. Excite Media’s client-success archive provides named examples across service categories.

Evidence: Excite Media reports that its John Barnes programme produced a 69.4% conversion increase, a 41.5% traffic increase and about 13,000 additional new users over five months compared with the preceding period. These are agency-reported results with a stated comparison period, not independently audited figures. Read the John Barnes case study.

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 growth and acquisition systems

Best for: Businesses with validated offers and substantial acquisition activity that want SEO, paid media, funnels, conversion work and direct-response creative together.

Why it ranked: King Kong has broad acquisition capability and a clear commercial-growth orientation. Its public materials cover SEO, paid search, social advertising, conversion-rate optimisation, funnels and creative, which can suit businesses that prioritise direct response over a pure-play SEO relationship. King Kong documents this service breadth.

Evidence: Independent business coverage corroborates King Kong’s Melbourne roots, 2014 founding and rapid early growth story, but it does not independently validate all agency performance claims. Business News Australia’s profile is useful contextual evidence rather than campaign-proof evidence.

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

SEO plus paid acquisition under one roof: Consider First Page Australia or Online Marketing Gurus. Ask both to separate the SEO scope, paid-media scope and ownership of conversion work.
AI-search visibility alongside conventional SEO: Consider Searchmaxxed for an implementation-led SEO/AEO/GEO model, or Salt & Fuessel for a combined UX, web and GEO programme. Also compare our guides to agencies for Google AI Overviews and agencies for ChatGPT visibility.

Accounting or professional-services platform: Use a vertical shortlist as well as this broad guide; see Best SEO Agencies for Accountants in Australia.

FAQ

What should an online platform expect from an SEO agency?

A useful agency should assess crawlability, indexation, templates, internal linking, content gaps, commercial pages, conversion paths, analytics and technical ownership. For marketplaces and eCommerce sites, category, filter, product and duplicate-content handling are usually central.

Is AI SEO different from conventional SEO?

AI SEO is usually an umbrella term for conventional SEO plus work intended to improve a brand’s clarity in AI-mediated search. It does not replace technical SEO, useful content, credible evidence or conversion design. It also cannot guarantee AI citations.

What is AEO and GEO?

AEO is answer engine optimisation: structuring useful, verifiable information so answer-oriented search systems can retrieve it. GEO is generative engine optimisation: improving how brand information may be understood in generative search experiences. Both rely on evidence, entities, structured information and accessible pages.

Should I choose an SEO-only agency or a full-service agency?

Choose SEO-only when organic search is the core constraint and you already have strong paid media, creative and development capability. Choose full-service when site conversion, paid acquisition, UX and organic visibility need coordinated ownership.

Are agency case studies reliable?

They are useful evidence, not conclusive proof. Treat agency-reported metrics as directional until you have checked the time period, attribution method, baseline, client reference and relevance to your platform.

Decision rule

Choose the agency that can show the strongest evidence for your platform type, assigns named people to implementation, agrees to measurable commercial outcomes without guaranteeing them, and gives you contractual ownership of data and assets. If an agency cannot explain its first-90-day priorities, delivery responsibilities and exit terms in writing, do not shortlist it.
