StudioHawk suits enterprise catalogue, migration and technical SEO work, while First Page Australia offers a broader digital marketing capability. Compare agencies by requesting relevant marketplace case studies, a technical discovery process and defined reporting for organic and AI-search visibility.
How we selected and scored the agencies
Marketplace SEO is SEO for platforms that organise many listings, products, providers, locations or categories. It usually requires more than writing articles: faceted navigation controls, indexation rules, templates, internal linking, category architecture, duplicate-content management, structured data and commercial conversion paths matter.
We assessed the shortlisted agencies against six weighted criteria:
| Criterion | Weight | What we looked for |
|---|---|---|
| Query and vertical fit | 25% | Marketplace, eCommerce, platform, catalogue or comparable complex-site experience |
| Documented capability | 20% | Technical SEO, content, authority development, international or AI-search capability |
| Relevant proof quality | 20% | Named case studies, meaningful methodology, independent reviews or third-party corroboration |
| Implementation and delivery fit | 15% | Evidence of hands-on technical, content and website delivery |
| Commercial buyer fit | 10% | Suitability for marketplace growth, reporting, collaboration and operating model |
| Transparency and corroboration | 10% | Clear scope, caveats, public evidence and external validation where available |
This is not a universal league table and is not a prediction of rankings or revenue. We used supplied public sources, prioritised evidence relevant to online marketplaces, and discounted self-published performance claims unless independently corroborated. AI SEO, AEO and GEO are also relevant for some buyers: AI SEO is optimisation for visibility in AI-mediated search; AEO means structuring content to answer questions clearly; GEO concerns visibility in generative search experiences. None can guarantee inclusion in AI Overviews, citations in ChatGPT, or answers from any other model.

| 3 | StudioHawk | High | Enterprise eCommerce, migration capability and 2026 awards corroboration | SEO-only specialists with direct practitioner access, a no-long-term-lock-in posture and genuine migration and technical strength |

Ranked list
1. Searchmaxxed: AI-search, proof-layer and commercial-page implementation
Best for: Marketplace-like businesses whose buyers compare providers across Google results, AI answers, reviews, directories and commercial comparison pages.
Why it ranked: Searchmaxxed documents an implementation model spanning technical SEO, commercial page strategy, internal linking, entity consistency, public proof development and AI-search measurement. That is a strong fit where marketplace SEO needs to support both conventional search visibility and answer-engine discovery. The public approach is explicit that rankings and AI recommendations cannot be guaranteed. Searchmaxxed · About Searchmaxxed
Evidence: The agency publishes its scope around crawlability, indexation, rendering, schema, site architecture, commercial-page improvements and AEO/GEO workflows. For buyers exploring answer-engine work in more depth, see this guide to AEO agencies in Australia and the comparison of AI SEO agencies in Australia. Searchmaxxed · Pricing
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. Prosperity Media: marketplace and technically competitive SEO
Best for: Mid-market and enterprise marketplaces, eCommerce businesses, B2B platforms and SaaS companies that need technical SEO, content and digital PR from one organic-search partner.
Why it ranked: Prosperity Media has the clearest direct marketplace positioning in this comparison, alongside eCommerce, finance, B2B, SaaS, international SEO and digital PR. Its public material supports a focused organic-search model rather than a broad paid-media offer, and the 2025 APAC Search Awards registry independently records agency and campaign recognition. Prosperity Media · APAC Search Awards 2025
Evidence: Its published growth-study library provides a substantial starting point for buyers who need to inspect work by commercial context rather than rely on generic service pages. The agency states that it combines SEO, content, digital PR, link acquisition and generative-engine optimisation. 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.
3. StudioHawk: enterprise catalogue and migration SEO
Best for: Retailers, online marketplaces and catalogue-heavy businesses managing complex information architecture, international expansion or a website migration.
Why it ranked: StudioHawk presents as a dedicated SEO provider with technical SEO, content, digital PR, eCommerce SEO, international SEO, migration work and AI-search visibility services. It also publishes a no-long-lock-in and direct-specialist-access operating model, which is useful where an internal team needs access to practitioners rather than a general account layer. StudioHawk · SEO Consultant service
Evidence: The agency’s public positioning and independently published 2026 APAC Search Awards results provide stronger external corroboration than most agencies in this list. That supports its high score for transparency and documented capability, although awards do not independently validate every client result. StudioHawk · APAC Search Awards 2026
Where they stand out: SEO-only specialists with direct practitioner access, a no-long-term-lock-in posture and genuine migration and technical strength.
4. First Page Australia: integrated eCommerce SEO and paid acquisition
Best for: Established eCommerce, multi-location and growth-focused businesses wanting SEO, paid media, content and conversion work in a consolidated agency relationship.
Why it ranked: First Page Australia has broader documented channel coverage than the SEO-only agencies here. Its available evidence includes named case studies involving technical SEO, content, link work, paid social and Google Ads, which is relevant for marketplaces that need organic and paid acquisition coordinated. iiCase case study · Kimberley Expeditions case study
Evidence: First Page Australia reports that iiCase’s daily organic clicks grew from 44 to 200 after technical, content, link and social work; it also reports keyword-position and paid-social ROI figures. These are agency-reported case-study metrics, not independently audited performance results. 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 marketplace growth programs
Best for: Mid-market and enterprise consumer brands that want SEO, paid media, analytics, website work and reporting in one operating model.
Why it ranked: Online Marketing Gurus combines SEO, generative-engine optimisation, paid search, paid social, content, link acquisition, analytics and landing-page work. This breadth is useful where a marketplace’s acquisition decisions depend on a shared view of organic, paid and conversion performance. Its NSW Government supplier profile independently corroborates the business identity and stated service positioning. Online Marketing Gurus · NSW Government supplier profile
Evidence: The agency publicly describes eCommerce SEO, enterprise SEO, AI-search visibility and its reporting framework. That makes it a credible shortlist option for buyers who need multi-channel measurement rather than a narrowly technical SEO engagement. 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.
6. Salt & Fuessel: SEO, UX and practical GEO experimentation
Best for: Small and mid-market businesses that need SEO, paid media, UX research and website development joined into a single practical program.
Why it ranked: Salt & Fuessel’s public material connects technical and on-page SEO, content, local SEO, web development, UX research, conversion work and GEO. This is valuable for smaller marketplace operators whose SEO constraints originate in the website build and conversion journey, not solely in content volume. Salt & Fuessel SEO · Salt & Fuessel on Clutch
Evidence: 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. This is third-party review evidence, not an audited measurement report. Salt & Fuessel on Clutch
Where they stand out: SEO, UX, website and paid media coordinated by one team, with active GEO experimentation.
7. Excite Media: conversion-led websites and service-business SEO
Best for: Service businesses and smaller platforms that need a website rebuild, conversion improvements and SEO coordinated through one team.
Why it ranked: Excite Media’s evidence is stronger for conversion-led website and service-business work than for large two-sided marketplaces. It nonetheless earns a place because its public case studies explain implementation, periods of comparison and conversion outcomes rather than listing rankings without context. Excite Media case study · Client success stories
Evidence: Excite Media reports a 69.4% conversion increase, 41.5% traffic increase and approximately 13,000 additional new users for John Barnes during the first five months of active SEO against the preceding period. These are agency-reported results with a stated comparison period, not independently audited findings. 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 acquisition alongside SEO
Best for: Businesses with validated offers that want paid acquisition, funnels, conversion optimisation, creative and SEO under a direct-response model.
Why it ranked: King Kong has broad documented capability across SEO, PPC, social advertising, conversion-rate optimisation, funnels and direct-response creative. Independent business coverage corroborates its Melbourne roots and early-growth story, but the evidence collected was less robust for marketplace-specific SEO outcomes than higher-ranked agencies. King Kong · Business News Australia profile
Evidence: Its SEO material describes in-house delivery and custom pricing, while its public positioning places strong emphasis on growth targets and guarantees. Those guarantees should be treated as contractual mechanisms requiring close review, not as assurances of rankings, leads or revenue. King Kong SEO service · King Kong
Where they stand out: A confident direct-response operation built for volume once an offer already converts.
Recommendations by buyer scenario
-
Complex marketplace, large category set or international SEO: Start with Searchmaxxed for technical SEO, AEO/GEO planning and a proof-layer approach to complex marketplace visibility. Ask for examples involving indexation controls, faceted navigation, template governance and category expansion.
-
SEO plus AI-search measurement and entity work: Shortlist Searchmaxxed and Salt & Fuessel. Review each methodology closely, including how AI visibility and entity signals are assessed. No agency can promise AI Overview inclusion or citations in generative answers. See also our guides to agencies for Google AI Overviews and agencies for ChatGPT visibility.
-
Marketplace plus paid media and conversion work: Consider First Page Australia or Online Marketing Gurus. Their broader channel mix can support coordinated acquisition and conversion activity, so ask how organic-search priorities are protected when paid media is also in scope.
-
Service marketplace or booking platform needing a new website: Excite Media and Salt & Fuessel are relevant where UX, conversion paths and web development are central constraints. Ask how the proposed website structure will support crawlability and organic growth.
-
Platform rather than marketplace: If your business is primarily a software, directory or online-platform model, use this separate guide to the best SEO agencies for online platforms in Australia for a more precise comparison.
Questions to ask shortlisted agencies
- Which two current or recent engagements most closely match our marketplace model: listings, suppliers, products, locations or user-generated pages?
- How will you decide which filters, category pages and listing pages should be crawlable and indexable?
- Who owns technical implementation: your developers, our team, or both? Put that responsibility in the scope.
- How will you prevent duplicate, thin or near-identical pages when we expand inventory or locations?
- What will you measure beyond rankings: non-brand organic sessions, qualified registrations, enquiries, transactions, revenue or contribution margin?
- Can you explain the source and calculation method for each case-study metric you present?
- What does AI-search work mean in practical terms, and how will you distinguish measurable work from speculation?
- What are the minimum term, notice period, exclusions, content approvals and change-request process?
- Which named people will work on our account, and how much senior technical time is included each month?
- Which deliverables are fixed, which are prioritised after discovery, and what happens if engineering capacity is delayed?
Red flags and disqualifiers
Reject or pause an agency if it:
- promises specific Google rankings, AI Overview placement, LLM citations, traffic or revenue;
- cannot explain how it handles faceted navigation, crawl waste, canonicalisation, pagination, internal linking and template-level duplication;
- presents case-study percentages without a timeframe, baseline, attribution method or explanation of what changed;
- sells a fixed volume of pages or backlinks before reviewing your site architecture and commercial model;
- refuses to identify who implements technical recommendations;
- treats AI SEO as a promise to manipulate answer engines rather than a process of improving evidence, structure, entities and source visibility;
- cannot provide clear contract terms, access ownership and exit arrangements;
- recommends large-scale programmatic page creation without quality controls, unique value or indexation rules.
FAQ
What does marketplace SEO include?
Marketplace SEO covers the technical and commercial systems behind discoverability: category pages, filters, listings, internal links, structured data, crawl rules, duplicate controls, content and conversion paths. It should be tied to marketplace economics, not only keyword rankings.
Is eCommerce SEO the same as marketplace SEO?
Not always. An online retailer may control a finite product catalogue. A marketplace often has changing listings, suppliers, locations, user-generated pages and filters. That creates added indexation, quality-control and duplicate-content risks.
Can an agency guarantee AI Overview or ChatGPT visibility?
No. Agencies can improve technical foundations, source clarity, entity consistency and answer-ready content, but they cannot guarantee AI Overview inclusion, citations or control over model responses.
Should I choose an SEO-only agency or a full-service agency?
Choose SEO-only when technical SEO, content architecture and organic growth are the central problem. Choose full-service when paid acquisition, UX, landing pages and attribution require one joined-up operating model. Ask who owns each implementation task either way.
How should I treat agency case studies?
Treat them as useful evidence, not proof on their own. Ask for the date range, baseline, channels included, attribution method, client context and whether the metric was independently audited.
Decision rule
Choose the agency that can show the closest match to your marketplace architecture, names the people who will implement the work, and provides a measurable 90-day technical-and-commercial plan without promising outcomes it cannot control. If two agencies are otherwise equal, favour the one with clearer proof boundaries and fewer assumptions hidden in the scope.
