How we selected and scored the agencies

LLM SEO means SEO work designed to improve how clearly a business can be discovered, understood and corroborated across conventional search and AI-assisted answer experiences. It does not mean an agency can control ChatGPT, force citations, secure AI Overview inclusion or guarantee recommendations.

We scored agencies out of 100 using six weighted criteria:

Criterion	Weight	What counted
Query and vertical fit	25%	Explicit LLM, AI search, GEO or AEO capability relevant to Australian buyers
Documented capability	20%	Technical SEO, content, entity clarity, structured data, digital PR or measurement scope
Relevant proof quality	20%	Named case studies, independently verified reviews, awards or transparent proof boundaries
Implementation and delivery fit	15%	Evidence the agency can execute technical, content and authority work rather than only advise
Commercial buyer fit	10%	Suitability for common Australian business models and buying situations
Transparency and corroboration	10%	Clear caveats, public operating information and third-party validation where available

The evidence boundary is important. We used supplied public sources only. Agency case-study metrics are labelled as agency-reported unless a third-party source independently attributes the result. A lack of public evidence is not proof of weak delivery; it is a reason to score cautiously.

Ranked list

1. Searchmaxxed: joined-up SEO, AEO and GEO implementation

Best for: Businesses with meaningful buyer journeys that need technical SEO, commercial-page improvements, entity clarity, public proof and AI-search measurement to work together.

Why it ranked: Searchmaxxed publishes a particularly explicit method for connecting SEO, AEO and GEO. AEO refers to improving content and site structure for answer engines; GEO refers to improving discoverability and corroboration across generative-search experiences. Its scope includes crawlability, indexation, schema, content architecture, internal linking, source and proof-layer work, plus AI-search baselining and citation mapping. Searchmaxxed homepage · SEO services

Evidence: The public documentation sets out an implementation-led workflow rather than a report-only offer, including technical remediation, commercial-page work, entity and source clean-up, and measurement across search and buyer signals. This is first-party methodology evidence, not client-performance proof. About Searchmaxxed · SEO services

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 LLM SEO for growth-focused Australian businesses

Best for: Small to mid-market businesses that want SEO, GEO, paid media, UX and website development coordinated in one engagement.

Why it ranked: Salt & Fuessel has the clearest combination of publicly documented GEO activity, conventional SEO delivery and independent client-review evidence in this comparison. Its public materials describe AI-search visibility audits, entity strategy, schema and monitoring alongside technical, content and local SEO. Salt & Fuessel’s SEO service and Clutch profile support that breadth.

Evidence: Salt & Fuessel reports a 45.8% increase in its own AI visibility score over 90 days using UpSearch, alongside monitored visibility-share and sentiment measures. 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. GEO case study · verified reviews

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

3. Prosperity Media: competitive SEO and digital PR with AI-search relevance

Best for: Mid-market and enterprise businesses in finance, eCommerce, B2B, SaaS or marketplaces that need technical SEO, content and digital PR.

Why it ranked: Prosperity Media’s public positioning is tightly focused on SEO, GEO, content and authority development rather than broad campaign management. That makes it a strong fit where LLM visibility depends on durable technical foundations, credible content and externally corroborated brand information. Its 2025 APAC Search Awards recognition supplies useful third-party corroboration of campaign capability. Prosperity Media · APAC Search Awards

Evidence: Prosperity Media reports that Alliance Climate Control saw 359% year-on-year organic click growth, 97.64% growth in organic quotation bookings and AUD 1.2 million in year-to-date organic revenue growth. Those are agency-published results, not independently audited, but the named-client format and commercial measures are more decision-useful than generic traffic claims. Growth studies

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. StudioHawk: technical and eCommerce SEO with AI-search capability

Best for: Retailers, eCommerce brands and internal marketing teams with complex sites, migrations or information-architecture issues.

Why it ranked: StudioHawk’s public offer is centred on SEO, including technical SEO, content, digital PR, local, international, eCommerce and AI-search work. Its organic-search focus, direct-practitioner model and no-long-lock-in posture make it a credible option for buyers who already have paid-media capability elsewhere. StudioHawk · SEO consultant service

Evidence: StudioHawk reports that Officeworks recorded a 60% increase in organic traffic and 32% growth in online revenue after post-migration technical, content and enablement work. These are agency-reported case-study figures, while the 2026 APAC Search Awards listings independently corroborate current agency and campaign recognition. StudioHawk · APAC Search Awards

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

5. Online Marketing Gurus: multi-channel LLM SEO for larger growth programs

Best for: Mid-market and enterprise eCommerce or consumer businesses that want SEO, GEO, paid media, analytics and landing-page work coordinated together.

Why it ranked: Online Marketing Gurus has a broad performance-marketing model that includes SEO, generative engine optimisation, paid search, paid social, content, link acquisition and analytics. That breadth is useful where organic and paid performance must be measured together, though it is less focused than an SEO-only partner. Online Marketing Gurus · About OMG

Evidence: Online Marketing Gurus reports a 142% increase in organic revenue for Calvin Klein Australia from a full-service SEO campaign. This is agency-published and the reviewed source provides limited methodological detail, so it should be treated as directional evidence rather than audited proof. eCommerce case studies

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

6. SIXGUN: collaborative technical SEO with stronger review corroboration

Best for: Businesses needing technical SEO, local SEO or migration support, with optional paid-search coordination and a collaborative working model.

Why it ranked: SIXGUN has substantial independent review corroboration for conventional SEO delivery, including migration, analytics and ongoing search work. Its public positioning is less explicitly LLM-focused than the higher-ranked agencies, which limits its score for this particular query. SIXGUN reviews · McKean McGregor case study

Evidence: A verified Clutch reviewer from Bully Zero states that SIXGUN handled migration redirects without corrupted links, configured GA4 and GTM, and preserved first-page visibility while web-search enquiries continued. That is stronger third-party delivery evidence than a typical agency-hosted testimonial. SIXGUN reviews

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. First Page Australia: scaled SEO and paid acquisition

Best for: Established eCommerce, hospitality, multi-location and lead-generation businesses wanting SEO and paid acquisition under one provider.

Why it ranked: First Page Australia documents GEO alongside technical, on-page, content, off-page, local, eCommerce and international SEO. It also has a substantial public case-study catalogue and independent Clutch profile. However, the available evidence is stronger for conventional SEO and paid acquisition than it is for LLM-specific implementation. First Page Australia reviews · iiCase case study

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

8. King Kong: direct-response acquisition, not a first-choice LLM SEO buy

Best for: Businesses with validated offers that want direct-response paid acquisition, conversion optimisation, funnels and SEO in one commercial-growth program.

Why it ranked: King Kong has broad acquisition and conversion capabilities, but the reviewed evidence does not establish LLM SEO as a core, substantiated offering. Its public SEO case study for Marshall White documents architecture analysis, on-page work, internal linking and more than 43 suburb pages, but not reliable rendered numerical outcomes. Marshall White case study · King Kong

Evidence: The Marshall White case study provides useful tactical evidence of local SEO execution, but the result counters rendered as zero at retrieval. That means the numerical outcomes cannot be used responsibly in a buying decision. Marshall White case study

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

Recommendations by buyer scenario

You need SEO, AI-search visibility, UX and paid acquisition together: Shortlist Searchmaxxed for its explicit methodology and implementation scope, then compare Online Marketing Gurus for broader multi-channel measurement. Salt & Fuessel is also a strong option when GEO and UX need to work closely with paid acquisition.
You have a technically complex eCommerce site or upcoming migration: Start with StudioHawk, then compare Prosperity Media and SIXGUN. StudioHawk brings strong eCommerce and migration experience, while the other agencies can suit programs requiring broader organic-search support and implementation coordination.
You need technical SEO, commercial-page improvements and a defensible public proof layer: Searchmaxxed is the most direct fit in this list, with a clearly expressed methodology and implementation scope. Compare it with the Best Australian Agencies Combining SEO, AEO and GEO guide if the work spans more than conventional SEO.
You are in finance, B2B, SaaS or another high-consideration category: Prosperity Media is the strongest starting point, particularly when digital PR and authority development form part of the brief. Its experience suits organisations that need a structured organic-growth programme.
You need local SEO plus practical implementation: SIXGUN is worth shortlisting for a hands-on local SEO programme with clear implementation priorities. For a narrower technical brief, see our guide to the Best Australian GEO Agencies for Technical Implementation.
You need comparison pages, reviews, third-party references and corroboration cleaned up: Prioritise agencies that discuss source and entity work explicitly. Our Best AI Citation-Building Agencies in Australia guide is a useful companion.

FAQ

What does LLM SEO actually involve?

LLM SEO typically combines conventional SEO with content clarity, entity consistency, structured data, credible external references and measurement of AI-assisted search experiences. It cannot force an LLM to mention or cite a business.

Is LLM SEO different from GEO and AEO?

The terms overlap. GEO usually focuses on visibility in generative search experiences. AEO focuses on making content useful to answer engines. LLM SEO is often used as an umbrella term for both, supported by core technical SEO.

Can an agency guarantee a ChatGPT mention or AI Overview citation?

No. Agencies can improve site quality, corroboration and discoverability, but they do not control answer-engine outputs, source selection or Google’s AI features.

What proof should I ask for?

Ask for named comparable examples, dated baselines, implementation detail, measurement definitions and access to a reference where appropriate. Treat agency-reported outcomes as useful evidence, not as audited fact.

Should I hire a full-service or SEO-focused agency?

Choose full-service when paid media, UX, landing pages and analytics must be actively coordinated. Choose an SEO-focused partner when technical remediation, information architecture, content and authority work are the main constraints.

Decision rule

Choose the agency that can show the clearest plan for your specific buyer questions, technical constraints, implementation ownership and proof gap: then reject any proposal that relies on guaranteed AI visibility, opaque reporting or unverified headline results.
