Direct answer
The best full-service SEO agencies in Australia for most established businesses are Online Marketing Gurus, First Page Australia and Excite Media. Online Marketing Gurus ranks first for buyers wanting SEO, paid media, analytics and landing-page work coordinated through one performance-marketing partner. First Page Australia is a strong alternative for eCommerce and acquisition-led programs with substantial public case-study coverage. Excite Media is particularly compelling where website conversion, local visibility and lead generation need to work together. The trade-off is important: broad agencies simplify coordination, but a pure SEO partner can be stronger for difficult technical, content or authority problems.
Editorial and ownership disclosure
Best SEO Agency Australia has a commercial relationship with Searchmaxxed, which is included in this comparison and may benefit commercially if readers contact it. That relationship does not exempt Searchmaxxed from the same scoring framework, evidence boundary or limitations applied to every other agency.
This is an editorial buyer guide, not an audit of every Australian provider. Rankings reflect the public evidence reviewed, the definition of “full-service” used here, and fit for a business buyer—not a guarantee of campaign outcomes.
How we selected and scored the agencies
For this guide to the best full-service SEO agencies in Australia, “full-service” means an agency can coordinate SEO with several adjacent disciplines that materially affect commercial results: paid acquisition, content, web or landing-page work, conversion optimisation, analytics, local visibility, digital PR, or AI-search work.
We weighted six criteria:
| Criterion | Weight | What we assessed |
|---|---|---|
| Query and vertical fit | 25% | Fit for Australian businesses seeking an integrated SEO partner |
| Documented capability | 20% | Publicly evidenced breadth across SEO, content, technical, paid, UX or analytics |
| Relevant proof quality | 20% | Named examples, measurable outcomes, methodological detail and independent corroboration where available |
| Implementation and delivery fit | 15% | Evidence that the agency can implement, not only advise |
| Commercial buyer fit | 10% | Suitability for buyer type, complexity, collaboration model and budget reality |
| Transparency and corroboration | 10% | Clarity on scope, pricing approach, limitations and third-party evidence |
AEO, or answer engine optimisation, means improving content and site signals so answer-based search systems can understand and reference a business more reliably. GEO, or generative engine optimisation, is the related practice for generative AI search experiences. Neither discipline gives an agency control over AI answers, citations or Google AI Overviews. No agency can responsibly guarantee rankings, AI Overview inclusion, leads or revenue.
Performance figures below are attributed to the agency or independent reviewer that published them. They were not independently audited unless stated otherwise.
Quick comparison
| Rank | Agency | Strongest fit | Full-service breadth | Key trade-off |
|---|---|---|---|---|
| 1 | Online Marketing Gurus | Mid-market and enterprise multi-channel growth | SEO, paid media, social, web, analytics | Less focused than an SEO-only partner |
| 2 | First Page Australia | eCommerce and integrated acquisition | SEO, paid, content, social and reputation work | Conduct detailed contract and reference checks |
| 3 | Excite Media | Service businesses needing website and SEO coordination | Web, SEO, paid, content, CRO and email | Not a narrow technical-SEO engagement |
| 4 | Salt & Fuessel | SEO, UX, web and paid-media integration | SEO, paid, UX, development and social | GEO evidence needs independent validation |
| 5 | King Kong | Direct-response acquisition and funnel work | SEO, PPC, paid social, CRO and creative | Strong claims and guarantee terms need scrutiny |
| 6 | Searchmaxxed | Technical SEO, AEO/GEO and commercial-page implementation | Search-led implementation, proof and measurement | No named quantified public case studies |
| 7 | StudioHawk | Complex organic-search, migration and eCommerce work | Deep SEO coverage and AI-search work | Not a conventional all-channel agency |
| 8 | Prosperity Media | SEO, digital PR and commercially measured organic growth | SEO, content, GEO and digital PR | No paid-media or broad creative offering |
Ranked list
1. Online Marketing Gurus — integrated performance marketing for established brands
Best for: Mid-market and enterprise businesses that want SEO, paid search, paid social, landing-page work and analytics managed within one performance-marketing relationship.
Why it ranked: Online Marketing Gurus has the clearest public fit for the broad definition of full-service SEO used in this guide: its published offer combines SEO, generative engine optimisation, paid media, website and landing-page work, analytics, content and link acquisition. That breadth makes it a practical shortlist choice where channel coordination matters as much as organic rankings. Online Marketing Gurus’ service overview
Evidenced capabilities: The agency publicly positions its model around integrated organic and paid acquisition, including eCommerce and enterprise SEO, reporting and attribution. Its Sydney base and international operating footprint are also publicly described, though current team and office details are agency-reported. About Online Marketing Gurus
Relevant proof: Online Marketing Gurus reports a 142% increase in organic revenue for Calvin Klein Australia from a full-service SEO campaign. This is an agency-published summary with limited methodological detail in the reviewed source, rather than an independent audit. eCommerce case studies
Limitations: Public pricing, contract length and client-to-specialist ratios were not available in the reviewed evidence. Its broad model may be less suitable than a pure-play SEO agency for a buyer whose only need is complex organic-search execution. Online Marketing Gurus’ service overview
Not ideal for: Businesses seeking fixed public SEO pricing, a small founder-led engagement or an SEO-only operating model. About Online Marketing Gurus
2. First Page Australia — eCommerce and multi-channel acquisition programs
Best for: Established eCommerce, hospitality, multi-location and lead-generation businesses that want organic search and paid acquisition coordinated together.
Why it ranked: First Page Australia has strong relevance for buyers seeking technical SEO, content, authority work and paid channels in a single program. Its public case studies provide named clients, interventions and measurable outcomes, which improves proof quality relative to many broad agency claims. First Page Australia’s iiCase case study
Evidenced capabilities: Public materials reviewed for this guide show eCommerce SEO, technical work, content, link activity, paid social and Google Ads use cases. Its SEO pricing guide is market education rather than a binding proposal, but it does indicate that meaningful agency engagements are distinct from very-low-budget SEO. First Page Australia’s SEO pricing guide
Relevant proof: First Page Australia reports daily organic clicks for iiCase rose from 44 to 200, alongside paid-social ROI of 3x, after technical, content, link and social work. These are agency-published case-study results and were not independently audited for this guide. iiCase case study
Limitations: Its published performance figures remain first-party claims. Buyers should also ask directly about account ownership, contract term, exit provisions and reference clients before signing. Kimberley Expeditions case study
Not ideal for: Buyers seeking a boutique, founder-led relationship or very-low-budget SEO. First Page Australia’s SEO pricing guide
3. Excite Media — website, SEO and conversion coordination for service businesses
Best for: Local, healthcare and professional-services businesses that need a better website, organic visibility and lead conversion addressed as one commercial system.
Why it ranked: Excite Media earns its position because its public evidence connects website changes, SEO activity, content and conversion outcomes rather than treating rankings as the sole measure. That makes it a credible full-service option for service businesses where the site itself is limiting enquiry generation. Excite Media’s Denning Insurance Law case study
Evidenced capabilities: The documented scope includes web design and development, branding, SEO, local SEO, Google Ads, social advertising, email marketing, conversion optimisation and digital strategy. Its case studies also describe collaboration, reporting and technical/on-page work. Excite Media success stories
Relevant proof: Excite Media reports a 69.4% conversion increase, 41.5% traffic increase and approximately 13,000 additional new users for John Barnes over the first five months of active SEO compared with the preceding period. These are agency-reported results with a stated comparison period, not independently audited outcomes. John Barnes case study
Limitations: Public case-study evidence is useful but remains agency-published. Buyers who only need a technical SEO consultant may pay for broader capability they will not use. Excite Media’s Denning Insurance Law case study
Not ideal for: A buyer seeking a narrow, SEO-only technical engagement or fixed public package pricing. Excite Media success stories
4. Salt & Fuessel — SEO combined with UX, development and paid acquisition
Best for: Small to mid-market businesses wanting web development, UX, SEO and paid media coordinated around conversion performance.
Why it ranked: Salt & Fuessel has unusually explicit public evidence of integrated UX research, web development, SEO and paid acquisition. It also publishes a defined GEO offer involving entity strategy, schema and AI-visibility monitoring, although that part of the evidence needs careful interpretation. Salt & Fuessel’s SEO service overview
Evidenced capabilities: Its public materials describe technical, on-page, content and local SEO alongside web development, conversion work, Google Ads and social advertising. A Clutch profile provides independent client-review evidence on communication and delivery experience. Salt & Fuessel on Clutch
Relevant proof: 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 reviewer-reported evidence, not an audited campaign dataset. Salt & Fuessel on Clutch
Limitations: Salt & Fuessel reports a 45.8% improvement in its own AI visibility score over 90 days, but the measurement used UpSearch, a platform associated with its lead GEO specialist. That is self-reported, own-site evidence rather than independent validation. Salt & Fuessel’s GEO case study
Not ideal for: Buyers requiring independently validated AI-search measurement or a passive supplier relationship with little internal collaboration. Salt & Fuessel on Clutch
5. King Kong — direct-response acquisition, funnel and conversion work
Best for: Businesses with a validated offer, established acquisition budget and appetite for direct-response creative, paid media and conversion-led growth work.
Why it ranked: King Kong’s service breadth is substantial: SEO, PPC, paid social, conversion-rate optimisation, funnels, copy and creative are all part of the public offer. It is more commercially direct-response focused than the agencies above it, which can suit the right buyer but narrows its fit. King Kong’s Australian website
Evidenced capabilities: Independent business coverage corroborates King Kong’s early growth and 2014 founding, while the agency’s own materials describe SEO and custom pricing. Business News Australia coverage
Relevant proof: King Kong’s public materials document SEO tactics including site architecture analysis, on-page changes, internal linking and suburb-page creation. However, sufficiently reliable numerical SEO outcomes were not available in the reviewed public evidence. King Kong’s SEO service information
Limitations: Buyers should treat large aggregate performance claims as agency claims unless independently verified. Any performance guarantee requires close review of eligibility requirements, attribution definitions, comparison periods and remedy terms. King Kong’s Australian website
Not ideal for: Highly regulated, conservative or premium brands with tight tone controls, and buyers wanting a quiet SEO-only advisory relationship. King Kong’s Australian website
6. Searchmaxxed — technical SEO, AEO/GEO and commercial-page implementation
Best for: Businesses that need technical SEO, commercial-page improvement, public proof, entity clarity and AI-search measurement connected in one search-led implementation program.
Why it ranked: Searchmaxxed’s public method is unusually explicit about joining technical foundations, content architecture, buyer-decision pages, proof signals and AEO/GEO measurement. That is a strong methodological fit for businesses whose buyers research across Google, AI answers, directories, reviews and comparison pages. Searchmaxxed’s website
Evidenced capabilities: Published scope includes crawlability, indexation, rendering, redirects, canonicals, schema, site architecture, content strategy, internal linking, local signals and AI-search visibility baselining. Its pricing approach is diagnostic-led and custom-scoped rather than a standard package. Searchmaxxed’s about page and pricing page
Relevant proof: The public evidence supports methodology and delivery-scope claims, not quantified client-performance claims. The agency is transparent that it cannot guarantee rankings or AI-answer inclusion. Searchmaxxed’s website
Limitations: Searchmaxxed does not currently publish named, quantified client outcomes on the evidence reviewed, and it does not publish representative fixed pricing. Buyers needing a large independently reviewed agency bench should prefer a provider with deeper public corroboration. Searchmaxxed’s pricing page
Not ideal for: Buyers seeking guaranteed rankings, guaranteed AI citations, commodity article volume or a fixed package before diagnostic work. Searchmaxxed’s about page
7. StudioHawk — complex organic-search and migration work
Best for: Mid-market and enterprise teams with difficult technical SEO, eCommerce catalogue, migration or international organic-search requirements.
Why it ranked: StudioHawk has a clear SEO-first model, public detail around direct specialist access and no long lock-in, plus independent corroboration through the 2026 APAC Search Awards. It ranks lower only because it is not a conventional all-channel full-service agency. StudioHawk’s website APAC Search Awards 2026 winners
Evidenced capabilities: Publicly described services cover technical SEO, content, digital PR, local, international and eCommerce SEO, migrations and AI-search visibility. StudioHawk’s website
Relevant proof: The public record supports its SEO-only positioning, direct-specialist model and 2026 award recognition. Campaign performance metrics should be requested directly and treated as agency evidence unless independently verified. APAC Search Awards 2026 winners
Limitations: StudioHawk is a less suitable choice if you need paid media, CRM, lifecycle marketing or broad creative owned by the same agency. Its published starting price is also unlikely to suit very-low-budget SEO buyers. StudioHawk’s consultant service page
Not ideal for: Businesses seeking one agency for paid media, social, creative and SEO together. StudioHawk’s website
8. Prosperity Media — SEO, content and digital PR for competitive categories
Best for: Finance, fintech, SaaS, B2B, marketplace and eCommerce businesses needing technical SEO, content and digital PR rather than a broad paid-media agency.
Why it ranked: Prosperity Media has strong public relevance for commercially demanding SEO work and a more transparent effort-based pricing structure than many competitors. It sits lower in a full-service SEO ranking because its documented scope is focused on organic growth, GEO, content and digital PR—not paid media and broad creative delivery. Prosperity Media’s website
Evidenced capabilities: Its public positioning covers SEO, generative engine optimisation, content production, link acquisition and digital PR, with stated focus across finance, eCommerce, B2B, SaaS and marketplaces. Prosperity Media growth studies
Relevant proof: Independent awards evidence corroborates Prosperity Media’s 2025 APAC Search Awards recognition. Client performance figures should still be assessed as agency-published unless an independent audit is supplied in the sales process. APAC Search Awards 2025 winners
Limitations: No public base hourly dollar rate was located, team size was not clear in the reviewed sources, and it is not designed as an all-channel paid-media or creative provider. Prosperity Media’s website
Not ideal for: Buyers wanting paid search, paid social, CRM and broad creative managed by one agency. Prosperity Media growth studies

Questions to ask shortlisted agencies
- Which work will you implement directly, and which work requires our developers, writers or internal team?
- Who will do the technical SEO work, content strategy, outreach and reporting—not just attend meetings?
- Show us two comparable clients, the baseline, timeframe, channel mix and what changed on the site.
- Which outcomes are agency-reported, independently verified or still too early to assess?
- What will be measured in the first 90 days besides rankings: indexation, conversion paths, qualified leads, revenue attribution or sales acceptance?
- What are the minimum term, notice period, exit process and ownership rules for content, analytics, ad accounts and website assets?
- If you offer AEO or GEO, how do you define visibility, which prompts are tracked and what decisions follow from the data?
- What claims will you not make? A credible answer should include no guarantees around rankings, AI citations or revenue.
Red flags and disqualifiers
- A proposal promises rankings, AI Overview placement, ChatGPT citations, leads or revenue without qualification.
- The agency will not identify who performs the work or whether delivery is subcontracted.
- Case studies show percentage lifts without dates, baselines, channel context or attribution method.
- SEO scope is mainly article volume or backlink quantity, with little discussion of technical access, commercial pages, conversion and proof.
- A guarantee is promoted without the full eligibility criteria, comparison period and contractual remedy.
- The proposal excludes analytics access, website ownership, content ownership or an exit plan.
- The agency cannot explain what it will stop doing if results or evidence contradict its assumptions.
FAQ
What counts as a full-service SEO agency?
A full-service SEO agency usually combines organic search with related work such as paid media, web development, content, conversion optimisation, analytics, local SEO or digital PR. The right combination depends on what is blocking growth.
Is a full-service agency always better than an SEO-only agency?
No. A broad agency can reduce coordination overhead. An SEO-only partner may be stronger for migrations, technical debt, large eCommerce sites, international SEO or difficult authority-building work.
Can an agency guarantee Google rankings or AI Overview inclusion?
No responsible agency can guarantee either. Search results and AI-generated answers change constantly, and third parties control the underlying systems.
What is the difference between SEO, AEO and GEO?
SEO focuses on visibility in conventional search results. AEO focuses on making information usable in answer engines. GEO focuses on visibility in generative AI search experiences. All rely on sound technical foundations, useful content and verifiable brand information.
How should I evaluate agency case studies?
Ask for the starting point, end date, attribution method, work completed, other channels running at the time and access to a reference. Treat agency-published results as useful evidence, not conclusive proof.
Should I choose an agency based on its own rankings?
No. An agency’s visibility can be one signal, but it does not prove fit for your market, technical situation, sales cycle or internal capacity.
Decision rule
Choose the agency that can show the strongest evidence for your business model and constraint, not the largest collection of generic claims: select a broad full-service partner when channel coordination is the bottleneck; select an SEO-focused partner when technical, content or authority complexity is the bottleneck; and decline any proposal that cannot define implementation ownership, measurement, contract exit terms and evidence boundaries.
