Australian businesses urged to measure AI search beyond mentions and clicks

Predicta Digital publishes a practical guide to following AI-influenced enquiries through to sales and gross profit

MELBOURNE, 28 October 2026 — Australian businesses investing in AI search should look beyond visibility scores and referral traffic when assessing whether that investment is paying off, according to Melbourne SEO agency Predicta Digital.

The agency has published How to Measure AI Search ROI: A Practical Guide for Australian Businesses, outlining how business owners can connect identifiable AI referrals and customer feedback with qualified enquiries, completed sales and campaign costs.

The guide addresses a measurement gap that can work in both directions. A customer may discover a business through an AI recommendation, then search for its name on Google before making an enquiry. Analytics may record the Google visit without revealing the earlier AI interaction. Conversely, growth in branded searches or direct visits does not prove that AI caused it.

“Being recommended in ChatGPT is useful to know. It does not tell a business owner whether the work is paying for itself,” said Tanya, founder of Predicta Digital.

“The next questions are whether suitable customers are finding you, what happens after they enquire and how much value those customers bring to the business.”

The release of the guide follows Australian research highlighting AI's role in purchase decisions. WPP Media's The Hidden Pathway research reported that three in four Australians used AI search to inform what they buy. The research includes AI-powered summaries within conventional search results as well as direct use of large language models. The headline figure should not be read as three in four Australians buying through ChatGPT.

Predicta's guide recommends that businesses:

Follow identifiable AI referrals from the landing page through to qualified enquiries and closed sales.

Ask customers how they found and compared providers, allowing them to name more than one source.

Keep tracked referrals and customer-reported AI influence against the same customer record to avoid counting a sale twice.

Assess gross profit against campaign costs, including a reasonable allocation of work shared with conventional SEO.

It also recommends reporting wider changes in branded search and direct traffic separately, rather than automatically assigning that growth to AI.

“A customer might tell you that ChatGPT recommended the business, then they checked your reviews and found you on Google,” Bhattacharya said.

“That information helps explain the journey. But if the same customer also appears in your tracked referrals, it is still one customer. The reporting should make the budget decision clearer.”

The guide advises businesses to choose a review period that reflects their sales cycle. A retailer can record a purchase quickly, while a clinic may need to follow a booking through to attendance and a mortgage broker may wait months for an enquiry to become settled business.

It distinguishes estimated returns under an attribution method from proof that AI search independently generated a sale. Visibility data remains useful for investigating where a business appears, but needs to be considered alongside customer outcomes.

The AI search ROI guide is available on Predicta Digital's website.
