Brisbane search demand surged, then slumped in 2026

01 · The headline number

Brisbane search demand fell 42% in a year

We pulled monthly Google search volume for 80-plus Brisbane service keywords, "plumber brisbane", "mortgage broker brisbane", "dentist brisbane" and the like, across 20 industries, from January 2024 through April 2026, then compared like-for-like windows: January–April 2026 against January–April 2025.

Demand fell 42% year-on-year, and it fell from a high: the same basket of searches had surged +34% from 2024 to 2025 before dropping away in 2026. By April 2026, demand sat about 22% below its early-2024 level.

The timing points in one direction. The break happens in 2026, the same window in which Google's AI Overviews scaled across Australia, and our companion study found AI Overviews now appear on roughly 38% of Brisbane search results. We can't prove causation from volume data alone, but the matched-window comparison is robust, and the most plausible single driver is the one reshaping every results page in the country: AI answers are absorbing searches that used to be typed, repeated, and clicked.

02 · The demand curve

The rise, the peak, and the fall

Here is total monthly search volume across all 20 tracked industries, every month from January 2024 to April 2026. Demand climbed to a peak of about 143,690 searches in March 2025, then fell away through 2026 to around 60,090 by April.

The 2026 fall is broad, not isolated. Of the 20 industries we tracked, 20 recorded lower demand in 2026 than in 2025. When almost every category turns down together, in the same window, it points to something happening at the level of the search engine rather than 20 separate local markets all cooling at once by chance.

03 · What Brisbane searches for

The demand league table

Average monthly searches in the January–April window of each year, for 2024, 2025 and 2026, with the year-on-year change at each step. Read a row left to right to watch each category rise into 2025, then fall in 2026. Lawyers, Web Design and Pest Control lead by volume; the smallest categories swing wildly on tiny numbers, so read those with caution. Brisbane's marketing keywords are the most savagely contested in the country, more on that below.

The decline is near-universal. 20 of the 20 categories fell in 2026. Be careful with the smallest rows, the marketing and niche categories swing violently because they sit on just a few hundred searches or fewer, where Google's volume buckets round hard. The big, stable categories, pest control, the trades, legal, are the reliable signal, and they're pointing down.

04 · The cost to compete

What a Brisbane click costs

Demand is only half the picture, the other half is what it costs to capture it. Here is the average cost-per-click (top-of-page, AUD) for each Brisbane category with enough advertiser data to report.

SEO Agency ($131) and Google Ads ($118) command the dearest clicks. Brisbane is the most expensive marketing market we measured anywhere: SEO clicks average about $131 and Google Ads about $118, well above Sydney or Melbourne. At the other end, Yoga and Vets are the cheapest to advertise against. Note that Paid Marketing returned no reliable cost-per-click, too few advertisers bid on those Brisbane-specific terms for Google to report a rate.

05 · Brisbane vs the nation

Where Brisbane is dearer, and where it's a bargain

Is Brisbane an expensive place to advertise? It depends on the category. We compared each industry's Brisbane cost-per-click to the national average. 16 of the 19 categories with data cost more here; 3 cost less. Green means Brisbane is cheaper than the national average, a relative bargain.

Web Design (+131%), SEO Agency (+73%), Accountants (+65%) cost the most relative to the national rate, the classic big-market bidding pressure. By contrast Air Conditioning (−3%), Digital Marketing (−5%), Real Estate (−54%) are genuine bargains, worth knowing before you set a bid cap off a national figure.

06 · What to do about it

Five takeaways for Brisbane businesses

1. Never size a budget off one year. The same keywords rose 34% then fell 42% in two years. Plan against the multi-year trend, not a single snapshot, and re-pull your category's volumes at least twice a year.
2. Assume AI is eating the top of your funnel, and measure it. Demand fell across 20 of 20 categories in 2026, alongside AI Overviews now on roughly 38% of Brisbane results. Shift the goal from "rank #1" to "be the source the AI cites", and track AI-answer visibility, not just classic rankings.
3. Defend the transactional, local queries. "[service] brisbane" and "[service] [suburb]" searches still convert and are the ones AI is least able to answer. Concentrate effort there rather than on the explainer content AI is absorbing.
4. Price paid search against Brisbane, not the nation. Costs swing wildly by category here. Set bid caps and channel budgets off the Brisbane figures in this report, not a generic national benchmark, or you'll mis-price both ends. It is how our team runs Brisbane Google Ads for clients.
5. Own organic and AI-citation visibility, it compounds. With demand falling and the dearest clicks in marketing itself, every lead earned through organic search, content and citations is worth multiples of a bought one. It is the focus of our Brisbane SEO work.
