How AI Overviews are reshaping accounting search in Australia

01 · The headline number

Accounting is the most AI-exposed industry in Australia

When we ran the trigger-rate analysis across all 18 industries in our dataset, we expected Legal or Healthcare to lead. Both are stuffed with the regulatory and informational content Google's AI was built to summarise. Accounting was the surprise.

Of 6,462 commercial accounting searches we tested, 3,439 returned a Google AI Overview. That's 15.4 percentage points above the national average, and the largest deviation of any vertical in the study. For comparison, Hospitality (the least exposed industry) sits at 9.1%.

The headline reads in two directions. For your customers, AI is now the default first answer for accounting questions. For your firm, the SEO playbook that built traffic over the last decade is being mediated by a competing surface that wasn't there in 2023.

02 · The intent breakdown

What kinds of searches actually trigger the AI

Trigger rate varies dramatically by what your customer is actually asking for. We split every accounting query into one of four intents (informational, commercial, transactional, navigational) and measured each separately. Here's what we found.

Informational queries are the danger zone. Things like "what is GST", "how does a BAS work", "tax deductions for sole traders". The AI returns an answer on 64.4% of them. If your content is structured around how-to and what-is formats, which most accounting content is, you're competing with the AI on more than 6 in 10 of those queries.

The transactional number surprised us. In other verticals we tested (Real Estate, Trades, Home Services), "I want to buy or hire something" queries push the AI to back off. Google prefers to keep transactional intent inside its ad inventory, where it earns. Accounting transactional queries don't behave that way: 61.1% of them trigger an AI Overview. When we dug into examples, the reason became clear. Australian transactional accounting queries usually carry a definitional component. "How much does an accountant cost in Sydney" reads like a price question, but Google's AI treats it as a request for an explainer and writes a definitional answer first.

Commercial intent (best accountants Melbourne, tax agent comparison) sits much lower at 33.4%. Navigational queries (Xero login, ATO portal) lower again at 19.3%. These are where your firm's pages still get the user's first impression.

03 · Mobile vs desktop

Mobile is +7.1pp more AI-exposed than desktop

We split the dataset by device to test a specific hypothesis. Agencies have been telling clients to audit AIO presence on desktop, because that's where SEO tools traditionally live. Was that misleading them? For accounting, yes. And significantly.

The +7.1pp gap between mobile and desktop AIO exposure on accounting is the second-largest in the entire study. Only Legal, at +7.2pp, is bigger. The likely reason: accounting questions skew toward quick mobile lookups (pricing, deadlines, deductions), which are exactly the queries Google's AI is built to answer.

Our recommendation: if your team or agency is running AIO presence reports for accounting clients on desktop, switch to mobile screenshots tomorrow. The 7-point gap means your reports have been systematically underselling the problem.

04 · The citation leaderboard

Government domains dominate accounting citations

This is the section where the data forced us to update our standing recommendations. Before running the study, our working assumption was that AI Overview citations would be dominated by Wikipedia, US news publishers, and long-form authority sites. That's roughly what US studies show. Australian accounting is different.

ATO.gov.au alone accounts for 20.4% of every AI Overview citation in our accounting sample. Add the other government sources visible in the data (my.gov.au, tpb.gov.au, moneysmart.gov.au, business.gov.au, jobsandskills.gov.au) and roughly 28% of citations are government. The figure rises further once you include CPA Australia (cpaaustralia.com.au) and similar regulator-adjacent sites.

The implication is straightforward, and it's a recommendation we'd give to every accounting client right now: you cannot displace the ATO from Google's AI answer. Don't try. Two productive responses instead.

• Be the second source. The ATO explains the rules. Your audience needs the next layer: what does this mean for a sole trader specifically, how does this change my BAS process, what's the practical workflow. You're not trying to outrank ato.gov.au. You're trying to be the source the AI cites alongside it.
• Be on Reddit. 822 accounting AIO citations point to Reddit threads (r/AusFinance, r/Accounting, r/AusBusiness). That's meaningfully structural to Google's AI in this vertical. Have a senior team member with a verified-expert profile answering questions there. We'd argue it's the highest-ROI citation channel for accounting right now.

Wider context: 72.6% of all AIO citations on accounting queries are Australian domains (.com.au, .gov.au, .edu.au, .org.au, .net.au). That's nearly 18 points above the dataset average of 54.9%. Australian accounting content has a real geographic advantage in Google's AI, if you can rank for it.

05 · Local intent

Your service pages are mostly safe

This is the good-news section. And it lands more decisively for accounting than for most industries we measured.

Add "near me", a suburb, or a city name to an accounting query and the trigger rate drops from 56.1% to 38.3%. A 17.7 percentage-point reduction. The AI is much less likely to interject on queries with explicit local intent.

The way we read this: Google's AI seems to know when a query has local intent and steps back. A user looking for "an accountant in Sydney CBD" doesn't need a definition of what an accountant does, they need to see a list of actual accountants. So the AI defers.

Translation for your firm: pages targeting "accountants Sydney CBD", "tax agent Brisbane North", "small business accountant [suburb]" are largely insulated. The pressure is on your informational content (the how-to and what-is blog posts), not on your service pages. If you've been worrying that AIO is going to eat your service-page traffic, the data says relax. Worry about your blog instead.

06 · Page-type safety map

Which of your pages feed the AI

We measured AIO trigger rate by what kind of page ranks #1 in the accounting SERP. The results are stark, and for accounting they're sharper than for almost any other vertical we tested.

When an accounting blog post ranks #1 for a query, an AI Overview appears on 82.1% of those SERPs. That's meaningfully higher than the 18-industry average (76.1%) and almost the worst-case scenario for any kind of content. Your highest-traffic blog posts are your most exposed assets.

What surprises us less, but still warrants stating clearly: homepages are remarkably safe at 18.6%. Service and location pages sit in between at 34.8%. The takeaway is not "kill your blog". It's that for every blog visit your top posts used to get, you should now expect roughly four in five searches to see the AI's answer first. That's a click-through-rate problem you need to plan for, not avoid.

Our view: the spread between blog content (82.1%) and homepage (18.6%) is wider for accounting than the spread between Accounting and Hospitality (the most and least exposed industries in the entire study). The kind of page that ranks for your business predicts AIO exposure more strongly than the industry you're in.

07 · What to do about it

Five actions we'd take if we ran an Australian accounting firm

1. Reframe your blog around "second-source" content. The ATO already explains the rules. Your audience needs the next layer: what does this mean for a sole trader specifically, how does this change my BAS process, what's the practical workflow. Aim to be the source the AI cites alongside ato.gov.au, not the one it replaces. (Practical tip: open your top 20 blog posts. For each, ask "could the ATO have written this?" If yes, rewrite the angle.)
2. Get on Reddit. Seriously. r/AusFinance, r/AusBusiness, r/Accounting. 822 of your industry's AIO citations are Reddit threads. Have a senior accountant with a verified-expert flair answering questions there for an hour a week. The cost is low, the citation upside is genuine, and it compounds. We rank this as the single highest-ROI marketing action for an Australian accounting firm in 2026.
3. Invest in service and location pages. They're insulated. "Tax agent [city]", "small business accountant [suburb]", "BAS services [region]" trigger AIO at 34.8%, vs 82.1% for blog content. These are the pages where ranking still means being the user's first impression. If you've been deprioritising location pages because they "feel SEO-spammy", reverse that decision.
4. Audit AIO presence on mobile, not desktop. Accounting has a +7.1pp mobile gap. If you've been reporting on AIO from desktop screenshots, your numbers are 7 points light. Run your next AIO audit from a mobile device and brace yourself for what you see.
5. Don't optimise your homepage for AIO. Homepage rankings trigger AIO only 18.6% of the time. The homepage is already where conversion happens. Let the blog and service pages carry the SEO load, and keep the homepage built to close.
