How Much Does a Cross-Engine AI Citation Audit Cost in Australia?

Why a Single Query Is Not an Audit

A question typed into ChatGPT once is one draw from a probabilistic system. Researchers at the University of St Gallen measured brand and source visibility across four AI search engines over a 46-day tracking window and found that a single query carries a standard error of 0.370 on the per-brand detection rate. A true 50% citation rate could therefore show up as anywhere near 0% or over 100% in that one attempt.

Independent coverage in Search Engine Journal reached the same conclusion, that a single before-and-after reading cannot separate a real change from ordinary noise. The same research measured exactly how the error rate drops as run count increases.

This is the mechanic that separates a free check from a priced audit. A free version stops at row one. Intelligent Resourcing's own tracker ran an average of 6.7 times per prompt across 157 tracked prompts in its most recent 14-day window (Intelligent Resourcing AEO Tracker, 22 July 2026), close to the range this research treats as reliable, though this reflects the tracker's observed activity rather than a stated internal policy.

What a Real SaaS Tracker Costs

The $99 to $399 a month range maps to real, published pricing from the category, checked directly on 23 July 2026, roughly $142 to $580 AUD at current exchange rates. These tiers match one of the market's own leading tools, so the comparison is against an actual product a business could buy today.

• Starter tier, $99 a month: ChatGPT only, 50 prompts tracked.
• Growth tier, $399 a month: three engines tracked (ChatGPT, Perplexity and Google AI Overviews), 100 prompts.
• Enterprise tier, custom quote: coverage across up to nine engines.

That mid-tier price works out to close to $4,800 a year for ongoing monitoring alone, before any content work to close the gaps it finds. A one-off diagnostic audit priced around half that annual figure includes root-cause detail a subscription tracker leaves out entirely.

One Prompt Worked Through in Full

On the prompt "best AI SEO agencies in Australia," Intelligent Resourcing was cited in 0 of 11 tracked runs, 0 of 3 on Gemini, 0 of 2 on AI Overview, 0 of 4 on Perplexity, and 0 of 2 on ChatGPT (Intelligent Resourcing AEO Tracker, 22 July 2026). The audit classified this as a content gap, not an authority gap. No page on the site targeted this exact query, while Formulate, StudioHawk and Prosperity Media were cited instead.

A content gap is closed by building the missing page, a matter of weeks. An authority gap needs sustained external reference building over months. Mistaking one for the other is the exact error a free check or a blended SaaS score cannot catch, since neither traces the absence back to a specific, fixable cause.

The audit's fix followed directly from that diagnosis:

• Build a dedicated page targeting this precise query and its close variants.
• Connect it to a supporting content hub.
• Add FAQ schema written to answer list-style, evaluative questions directly.

What You Get for the Price

A real audit's output shows exactly which prompts a brand is absent from and which competitors are cited in its place, rather than a single blended score. That granularity, shown above, is what turns a diagnosis into a fix instead of a guess.

A $99 to $399 monthly subscription reports a number, an audit explains it. Intelligent Resourcing's Strategic Blueprint is priced from AUD $2,500 plus GST for this kind of output, covering ChatGPT, Perplexity, Claude and Gemini. It sits inside Intelligent Resourcing's Generative Engine Optimisation service as the entry diagnostic, including a competitor citation map, a buyer question taxonomy by intent stage, and an AI-readiness check across schema, robots.txt and llms.txt configuration.

Intelligent Resourcing's AEO pricing breakdown sets out root cause classification and retainer options in full, including the four specific gap types an audit can surface and how each is fixed differently.

What to Check Before You Pay for Any Audit

Run each question past a provider before you sign. A real audit answers all five with a number.

1. Ask how many times each prompt was run. The same research recommends seven or more runs for brand-level tracking, eight or more when tracing to a specific page.
2. Ask whether results are sliced by branded versus non-branded queries. A blended number hides whether a brand is only found when someone already knows its name.
3. Ask whether citations trace to a specific page. Intelligent Resourcing's own case work found citations spread across more than 25 pages, not one hero article, so breadth was the mechanism.
4. Compare the audit price against a SaaS subscription over the same period. A $2,500 one-off diagnosis and a $99 to $399 a month tracker solve different problems.
5. Ask whether the recommendation is specific or generic. "Publish more content" is a sign the root cause was never actually classified.

Fit Check

A $2,500 audit is only worth paying for if there is something specific it needs to answer.

• Best for: teams that suspect they are invisible, or worse, being used without being named, and need to know exactly why before committing to an ongoing programme.
• Not for: brand-new sites with no published content yet, since there is nothing for an audit to trace back to a source.
• The trade-off: a proper audit costs more upfront than a free check or a subscription's first month, and returns a diagnosis instead of a guess.

The free version tells you there is a problem. The audit tells you which page to fix first.
