Key takeaways
- ChatGPT holds roughly 65-68% assistant share in the UK, Canada, and Australia, but Copilot takes a meaningfully bigger slice in the UK and Australia (11-13%) than in Canada (where Gemini edges ahead instead) — your tool needs to cover the right engines per market, not a generic global list.
- Google AI Overviews shows up less often outside the US: roughly 87% of US frequency in Canada, 83% in the UK, and 70% in Australia, according to ZipTie's 500-query sample. Budget your monitoring accordingly.
- Not every GEO tool treats country-level tracking the same way. Some gate it behind enterprise plans (Scrunch AI), some include unlimited countries on the entry tier (Otterly.AI, Peec AI), and some claim broad coverage that's disputed by competitors (Semrush).
- AI answers are noisy by nature — identical prompts can return meaningfully different cited sources from run to run — so a single snapshot from any tool, in any country, should never be treated as gospel.
- Promptwatch tracks ChatGPT, Gemini, Claude, Perplexity, Copilot, and Google AI Overviews/AI Mode with country and even city-level tracking, which matters a lot once you're running campaigns across three separate English-speaking markets with different engine mixes.
Why the UK, Canada, and Australia aren't just "English-speaking America"
I see this mistake a lot: a brand sets up AI visibility tracking once, assumes the US numbers roughly translate, and calls it done. They don't translate. The assistant mix is different, the frequency of AI Overviews is different, and even which content formats get cited can shift by market.
Start with assistant share. Data from Alphametic's 2026 breakdown puts ChatGPT at similar levels across all three countries (65-68%), but the runner-up is not consistent. In the UK, Copilot takes 13.38% of share, likely a hangover from Windows and Microsoft 365 penetration in British offices. Australia shows a similar Copilot bump at 11.56%. Canada is different: Copilot barely registers, and Gemini takes the number two spot at 12.35%. If your GEO tool only tracks ChatGPT and Perplexity, you're missing a real chunk of the conversation in two out of three markets.
Then there's Google AI Overviews frequency. ZipTie's testing (a 500-query sample) found AI Overviews triggering in about 20.9% of Canadian queries, 19.8% of UK queries, and 17% of Australian queries, against roughly 24% in the US. SeoProfy's independent estimate lands close to that for Canada and the UK too, though the exact number moves depending on methodology and query mix. The point isn't the precise percentage. It's that Australia, in particular, sees noticeably less AI Overview coverage than the US or UK, so a brand chasing AI Overview citations there needs patience and a tool that still tracks the country reliably even when hit rates are lower.
Perplexity's audience also skews toward these markets more than people assume. Technologychecker's data puts combined English-speaking markets (US, UK, Australia, Canada, New Zealand) at over 72% of Perplexity's enriched user base, with the UK alone at 9-17% depending on the cut. If you sell in the UK, Perplexity visibility isn't a nice-to-have.
What actually determines citations, regardless of country
Before picking a tool, it helps to understand what the data says drives citations in the first place, because this applies whether you're targeting London, Toronto, or Melbourne.
Promptwatch's analysis of citation share by domain rank bucket for August 2026 found something counterintuitive: domains with DR 46-75 captured nearly half of all ChatGPT citations, while top-tier DR 91-100 domains shrank from 7% to around 3% share by mid-August and stayed there. You don't need to out-authority the BBC or CBC to get cited. Mid-authority sites with specific, well-sourced content are doing most of the winning.
Social platforms matter unevenly too. Promptwatch's social citation data shows Reddit dominating ChatGPT citations at 5.19%, more than 20 times its share on any other platform for that engine, while AI Overviews and Grok lean toward YouTube instead (4.08% and 4.85%). X barely registers anywhere, under 0.25% across every engine tracked. None of this is UK/CA/AU-specific research, since Promptwatch's public data reports are global, but the underlying behavior (which content formats and sources get cited) carries across markets. If you want the country-level nuance, you'll need a tool that lets you run the same prompt set across regions and compare.
Comparing GEO tools for multi-country tracking
Here's where pricing and feature gates actually matter, because "supports multiple countries" means very different things across vendors.
| Tool | Entry price | Country/region handling | Engines covered | Good fit for UK/CA/AU |
|---|---|---|---|---|
| Promptwatch | $95/mo (Essential) | Country, state, and city-level tracking from Professional tier up | ChatGPT, Gemini, Claude, Perplexity, Grok, Copilot, AI Overviews, AI Mode, DeepSeek, Mistral, Llama | Strong — granular location tracking plus Reddit/YouTube citation data and crawler logs to see what AI actually reads per market |
| Semrush AI Visibility Toolkit | $99/mo standalone | Claims 32+ countries; a competing review disputes this, citing only 6 fully supported regions (US, UK, Canada, Australia, India, Spain) | ChatGPT, Gemini, Perplexity, AI Overviews | Decent if the disputed claim holds for your markets; worth testing directly before committing |
| Ahrefs Brand Radar | $199/mo for one AI platform, +$699/mo for all 6 | ~180 countries supported, broader than most competitors | ChatGPT, Perplexity, Gemini, Claude, AI Overviews, Copilot | Strong country breadth, but the full 6-engine package gets expensive fast |
| Otterly.AI | $29/mo (Lite) | 50+ countries on every tier, including entry | ChatGPT, AI Overviews, Perplexity, Copilot by default; Gemini/Claude/AI Mode as paid add-ons | Good budget option, but you'll pay extra to cover Gemini in Canada where it outranks Copilot |
| Peec AI | ~€70-89/mo (Starter) | Unlimited countries and seats even on entry tier | ChatGPT, Perplexity, Google Search/AIO by default; Claude and Gemini as add-ons | Reasonable for agencies running several UK/CA/AU clients without per-country fees |
| Scrunch AI | $250/mo (Core) | Only 1 country, 1 persona, 1 language on Core; multi-country locked behind custom Enterprise | ChatGPT, Perplexity, AI Overviews, Copilot (Core); 9 LLMs on Enterprise | Weak for multi-market brands unless you're ready for an Enterprise deal |
| Profound | Free trial (1 region), custom Enterprise pricing | Custom regions/languages on Enterprise only | Up to 9 engines on Enterprise | Capable but pricing opacity makes it hard to plan a UK/CA/AU rollout without a sales call |
A few things stand out when you line these up. First, "countries supported" claims are inconsistent between vendors and even between a vendor's own marketing and independent reviews, so treat any number above as a starting point for a demo conversation, not a final answer. Second, the tools that gate country tracking behind enterprise tiers (Scrunch, and to a lesser extent Profound) make sense for a single large brand running one market carefully, but they're a bad fit if you're an agency or multi-region brand juggling the UK, Canada, and Australia on one budget.
Engine coverage: match the tool to the market, not the other way around
Given the assistant-share differences above, here's a practical rule: don't buy a GEO tool and then figure out which engines it happens to track. Decide which engines actually matter in each of your markets first, then check the tool covers them.
For the UK and Australia, Copilot coverage is non-negotiable if you're serious about AI visibility, since it holds double-digit assistant share in both. Many entry-tier plans (Otterly's Lite, for example) treat Copilot as a paid add-on, which quietly inflates your real monthly cost once you add it back in.
For Canada, Gemini matters more than Copilot. If a tool's base plan skips Gemini or charges extra for it, that's a bigger problem for a Canada-focused brand than it would be for a UK one.
Across all three markets, Perplexity deserves more attention than its US-centric reputation suggests, given how much of its user base sits in exactly these English-speaking regions.
Don't trust a single snapshot, anywhere
This is true globally but worth repeating for multi-country setups specifically, because the temptation to run one tracking pass per market and call it done is strong when budgets are tight.
An arXiv study cited by Forbes found that identical repeated prompts to Gemini returned overlapping cited sources only about 30% of the time, while Perplexity's overlap sat closer to 50%. Conductor's analysis of 14,000 API calls found purchase-intent prompts were the least stable query type of all, with only about 4 of 10 brands appearing consistently across repeated runs of the same prompt. A Semrush analysis by Kevin Indig found only 25% overlap in cited sources between ChatGPT's Instant and Thinking modes for the same query.
What this means practically: if you check your UK visibility once in March and once in September and see a drop, that might be a real trend, or it might be noise from the engine's own instability. The fix isn't a smarter single query, it's frequent, repeated tracking with enough prompt volume per market to smooth out the noise. Perplexity's citation set is the most stable of the major engines per Promptwatch's average-sources-per-response data, almost exactly 10 sources with barely any daily movement, which makes it a decent "GEO test bench" if you want a market where changes you see are more likely to reflect your content rather than engine volatility.
A workable setup for a UK/CA/AU brand
If I were setting this up today for a brand active in all three markets, I'd do a few things in order.
First, pick a tool that treats country-level tracking as a core feature, not an upsell. Promptwatch handles this with country, state, and even city-level tracking from its Professional tier, which matters once you're comparing London against Manchester, or Toronto against Vancouver, not just country-level averages. It also tracks the full spread of engines relevant here, including Copilot for the UK/Australia and Gemini for Canada, plus Reddit and YouTube citation tracking that most monitoring-only tools skip entirely.
Second, build separate prompt sets per market rather than translating one US-centric list. A "best project management software" prompt behaves differently when run against a UK persona versus an Australian one, both in which products get recommended and in which sources get cited.
Third, check crawler logs if the tool offers them. Knowing whether ChatGPTBot or PerplexityBot is actually hitting your UK-specific landing pages tells you something no citation dashboard can: whether AI crawlers can even reach the content you're trying to get cited.
Fourth, treat the first month of data as a baseline, not a verdict. Given how unstable individual prompt responses are, you want at least 4-6 weeks of repeated tracking before drawing conclusions about whether you're gaining or losing visibility in any one market.
For teams exploring the broader category before committing, the GEO software directory at bestgeosoftware.com is a reasonable place to browse additional options beyond what's covered here, and ai-rank-tools.com is worth a look if rank tracking specifically (rather than full GEO) is your main need.
Final word
The UK, Canada, and Australia get lumped together constantly because they're English-speaking and culturally adjacent to the US, but the AI assistant landscape in each one is genuinely different. Copilot matters in two of the three and barely registers in the third. AI Overviews shows up less often in Australia than anywhere else in this comparison. Reddit dominates ChatGPT citations globally, but nobody's published country-specific data confirming that holds identically in Melbourne versus Manchester, so don't assume it does without checking your own data.
Pick a tool that lets you check, rather than one that forces you to assume.
