Luminary fits enterprise teams planning a substantial website or digital-platform rebuild. Compare shortlisted agencies by asking for their entity process, evidence standards, reporting method and relevant Australian case studies.

How we selected and scored the agencies

This guide uses “knowledge graph development” in the practical business sense: improving the consistency, structure and corroboration of information about a company, its services, people, locations and claims across its website and relevant public sources.

It is not a promise that an agency can create or control Google’s Knowledge Graph. Nor is it a claim that an agency can control AI answers. GEO (generative engine optimisation) is work intended to improve a brand’s eligibility to be understood and cited across AI-assisted search experiences. AEO (answer engine optimisation) focuses on making information easier for answer systems to retrieve and present. Entity SEO is the underlying work of making the business and its relationships unambiguous.

Agencies were scored out of 100 using six weighted criteria:

The evidence boundary is deliberately narrow: rankings rely only on the supplied public sources. A high score means the agency is comparatively well-supported for this specific brief, not that it will produce identical results for every business.

Quick comparison

Ranked list

1. Searchmaxxed: knowledge-graph foundations tied to commercial search implementation

Best for: Growth-stage SaaS, eCommerce, B2B, professional-service and multi-location businesses that need entity clarity, technical fixes, commercial-page improvements and public proof to work as one search programme.

Why it ranked: Searchmaxxed has the closest public methodological fit to this query. Its documented approach combines technical SEO, schema, architecture, entity and source cleanup, prompt and citation mapping, public proof development, and AI-search visibility measurement. This is a sensible operating model for buyers who see knowledge-graph development as a business-information problem rather than a schema-only task. Searchmaxxed’s GEO service and service overview describe that integrated scope.

Evidence: The public offer covers crawlability, indexation, rendering, canonicals, schema, content architecture, entity consistency and corroborating proof across relevant external surfaces. It also states clear boundaries around rankings and AI answers, which is a positive transparency signal for a category prone to inflated claims. Searchmaxxed’s About page outlines its audit-first and implementation-led model.

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, web, UX and acquisition work

Best for: Small and mid-market businesses that want GEO experimentation alongside SEO, web development, UX research, paid media and conversion work.

Why it ranked: Salt & Fuessel documents a defined GEO service that includes entity strategy, schema, AI-search audits and monitoring, while also offering practical website and acquisition delivery. That breadth makes it useful where poor entity clarity is connected to a dated site, weak user journeys or fragmented acquisition activity. Salt & Fuessel’s GEO service page describes this combined approach.

Evidence: A verified Clutch reviewer for Punchy Digital Media reports more than 20 qualified leads per month, 43% higher website traffic and better conversion rates following SEO, Google Ads and UX/UI work. Those results support broader delivery capability, though they are not proof of knowledge-graph outcomes. Read the Salt & Fuessel Clutch profile.

Salt & Fuessel reports a 45.8% increase in its own AI-visibility score across 90 days, measured using UpSearch, alongside monitored visibility-share and sentiment changes. This is relevant GEO evidence, but it remains a self-case study rather than independent validation. Read the agency’s self-reported GEO case study.

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

3. Prosperity Media: authority, technical SEO and digital PR for competitive markets

Best for: Mid-market and enterprise businesses in finance, fintech, eCommerce, SaaS, B2B or marketplaces that need technical SEO, content and authority work under one organic-search partner.

Why it ranked: Prosperity Media has a strong fit where “knowledge graph development” means building a credible, corroborated brand presence through technical SEO, content and digital PR. Its public positioning includes GEO and AI search, while its broader organic-search capability is suited to demanding commercial categories. Prosperity Media’s service overview and growth-study library support that positioning.

Evidence: The agency publicly documents SEO, GEO, content, digital PR and link-acquisition services, with case-study material focused on commercial organic-search programmes. It also received independent recognition in the 2025 APAC Search Awards results, which is useful corroboration of agency standing but not a guarantee of fit for an individual account. See the 2025 APAC Search Awards winners.

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. Luminary: enterprise information architecture and digital-platform transformation

Best for: Government, enterprise, charity and corporate organisations rebuilding complex websites, CMS platforms or digital experiences where information architecture, accessibility and governance matter as much as search.

Why it ranked: Luminary is not a narrow GEO provider, but it is unusually relevant when the knowledge-graph issue begins with fragmented systems, inaccessible content, inconsistent information and a complex website estate. Its SEO and GEO capabilities sit within broader strategy, UX, engineering, hosting and optimisation services. Luminary’s UNICEF case study demonstrates this platform-led delivery model.

Evidence: Luminary reports that, within two months of the UNICEF Australia relaunch, conversion rate rose 79% against a comparable three-year average, Lighthouse SEO score moved from 79% to 92%, site errors fell 99%, and site health improved 37%. These are agency-reported metrics accompanied by named client testimony, not independently audited performance results. Read the UNICEF Australia case study.

The rebuilt UNICEF site received the Australian Web Awards’ McFarlane Prize for Excellence, according to Luminary’s award report. Luminary’s award announcement provides the relevant context.

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

5. Online Marketing Gurus: multi-channel measurement and enterprise-scale acquisition

Best for: Mid-market and enterprise brands that need SEO, GEO, paid media, content and analytics coordinated through one operating model.

Why it ranked: Online Marketing Gurus is a practical option when entity and AI-search work must sit alongside paid search, paid social, landing-page improvements and attribution. The breadth is valuable for organisations that need consolidated reporting and experimentation across channels rather than a pure-play organic relationship. Online Marketing Gurus’ homepage outlines this multi-channel model.

Evidence: Its public materials include SEO, GEO, paid media, content, analytics and website services, while an NSW Government supplier profile independently corroborates the operating business and its digital-marketing service positioning. View the NSW Government supplier profile.

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

6. First Page Australia: integrated SEO and paid acquisition for growth programmes

Best for: Established eCommerce, lead-generation, multi-location and hospitality businesses wanting SEO, paid media and conversion activity managed together.

Why it ranked: First Page Australia has broad SEO coverage, including technical, local, eCommerce and international SEO, plus a public GEO and AI-search positioning. Its case studies show practical experience with technical work, content, links and paid acquisition. First Page Australia’s iiCase case study is a representative example.

Evidence: First Page reports that iiCase daily organic clicks increased from 44 to 200 following technical, content, link and social work, while paid social returned 3x ROI. This is agency-reported campaign evidence, not an independently audited result. Read the iiCase case study.

A Clutch profile displayed 14 reviews and a 5.0 overall score at retrieval, providing some independent evidence of client experience and delivery, although review-platform snapshots change over time. View the First Page Australia Clutch profile.

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

7. Supple Digital: conventional SEO, content and web support for SMBs

Best for: Australian small and medium businesses that need SEO copywriting, website changes and ongoing search work from one supplier.

Why it ranked: Supple Digital has credible evidence of conventional SEO, content and web delivery, including client feedback that supports its ability to translate search requirements into brand-aware copy. It ranks lower because public evidence for dedicated GEO, entity strategy and AI-search measurement is less developed than the agencies above. Supple Digital’s About page provides background on its broader SEO-led operating model.

Evidence: A verified Clutch reviewer for Mighty Collectibles says Supple handled competitor analysis, keyword research, copywriting and web development, and that the dedicated writer reflected the brand and customer language. No quantified uplift was published. Read Supple Digital’s Clutch reviews.

Supple also published an internal SEO experiment describing growth from zero to 200,000 monthly views through site structure, internal linking and keyword strategy. That is useful tactical evidence, but it is an agency self-test rather than an independently validated client result. Read the Supple experiment.

Where they stand out: Long-running Australian SEO delivery with transparent, well-documented service scopes.

8. King Kong: direct-response acquisition rather than knowledge-graph-led GEO

Best for: Businesses with validated offers that want paid acquisition, funnels, CRO, direct-response copy and SEO in a commercially aggressive growth programme.

Why it ranked: King Kong has broad acquisition capability and a clear direct-response position, but the supplied evidence provides limited reliable support for GEO, entity SEO or knowledge-graph development. It therefore ranks as a broader growth-marketing alternative rather than a primary recommendation for this exact brief. King Kong’s homepage explains its paid, funnel and SEO service mix.

Evidence: Its public Marshall White case-study material documents architecture analysis, on-page work, internal linking and the creation of more than 43 suburb pages. That implementation detail is relevant to local search structure, but the numerical result counters could not be treated as reliable in the reviewed evidence. See King Kong’s case-study library.

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

Questions to ask shortlisted agencies

1. What business entities, products, people, locations and claims will you map in the first 30 days?
2. Which problems are technical, which are content-related, and which require external corroboration?
3. What changes will you make directly, and what requires our developer, legal team or subject-matter experts?
4. How do you measure AI-search visibility without claiming control over AI answers?
5. Which sources will you monitor: Google Search Console, analytics, reviews, directories, publisher mentions, structured data or prompt sets?
6. Can you show a named example of entity cleanup, schema implementation, information architecture or source-corroboration work?
7. Are case-study results independently audited, client-reported, or agency-reported?
8. Who owns content, schema, dashboards, source lists and technical documentation if the engagement ends?
9. What assumptions underpin your forecast, and what would cause the plan to change?

Red flags and disqualifiers

• Promises of guaranteed rankings, guaranteed AI Overview inclusion or guaranteed citations in AI answers.
• “Knowledge graph” proposals that consist only of adding schema markup without validating the underlying business information.
• No distinction between first-party case studies, independent reviews and audited results.
• A refusal to explain who implements technical changes and who approves factual claims.
• AI-visibility reports that do not disclose the monitored prompts, competitor set, geography, timing or measurement method.
• An agency that proposes publishing unsupported claims, fabricated reviews or misleading directory profiles.
• Vague guarantees with no written qualification, attribution, exclusion or cancellation terms.
• A strategy based solely on article production when the actual blockers are entity ambiguity, broken site architecture, thin service pages or weak public proof.

FAQ

What does knowledge graph development mean for a business?

It means making information about your organisation consistent, structured and verifiable across your website and relevant public sources. The aim is clearer entity understanding, not control over Google’s Knowledge Graph or an AI model’s responses.

Is GEO the same as SEO?

No. SEO primarily addresses visibility in conventional search results. GEO considers how generative and answer-based systems may retrieve, interpret and cite information. The strongest programmes still require technical SEO, useful content and accurate business facts.

Can an agency guarantee an AI Overview or ChatGPT citation?

No. Agencies can improve technical accessibility, entity clarity, supporting evidence and measurement. They cannot guarantee that Google, ChatGPT or another answer engine will cite a brand for a particular query.

What proof should I request from a GEO agency?

Ask for named examples of technical implementation, entity mapping, schema, information-architecture changes, source corroboration and measurement methodology. Treat agency-reported traffic or revenue figures as useful context, not independent proof, unless audit evidence is supplied.

Does schema markup create a knowledge graph?

Not by itself. Schema can help machines interpret page content, but it cannot compensate for contradictory claims, missing evidence, poor site architecture or weak external corroboration.

Which buyer situation changes the recommendation most?

The biggest divider is whether you need a search programme or a platform transformation. For technical SEO, source layers and entity work, favour a GEO-focused implementation partner. For a complex enterprise CMS, accessibility and governance rebuild, favour a digital-platform agency with SEO and GEO capability.

Decision rule

Choose the agency that can document all four parts of your plan before contract signature: entity scope, implementation ownership, evidence sources and measurement method. If any one is vague, do not buy a “knowledge graph” package yet.
