How do you find Canadian lookalikes of US seed sites?
Part of Lookalike websites
The short answer
To find Canadian lookalikes of a US seed site, describe the seed by its subject and depth rather than its name, search for Canadian publishers covering the same subject in English and in Canadian French, then confirm each match with country level audience evidence. US seeds with a proven Canadian audience can stay; the rest guide the search.
Key takeaways
- A US seed is translated into a subject, a depth and a voice before the search starts; its name and its US angle do not travel.
- French counterparts are found through bilingual sites' own language versions, French subject vocabulary and French sections of national outlets, not by translating the English query.
- A Canadian audience is shown by country level popularity data and by delivery reports, not by a domain ending or a Canadian incorporation.
- A US seed with real Canadian readers can stay on a Canadian plan beside its Canadian lookalikes.
- The French share of a Canadian lookalike list follows the brief's languages and the forecast, with census data as context.
How do you find Canadian sites like a US seed site?
Clients hand over the sites they read, and for a Canadian campaign some of them are American. A US seed carries a US angle: US prices, US retailers, US regulations and US places. A Canadian lookalike shares the seed's subject and depth while covering the Canadian version of that subject. The lookalike websites hub covers seed based search in general; this guide covers the step across the border.
Five steps from a US seed to Canadian lookalikes
- Describe the seed without its name. Write one sentence each for its subject, its depth and its voice, from several recent articles, and note which parts are specific to the US.
- Swap the US specifics for Canadian ones. Replace US agencies, retailers, programs and places with their Canadian counterparts in the description.
- Search the Canadian description. Use exact phrases for Canadian programs and institutions, and the site: operator from Google's search help (opens in a new tab) to look inside Canadian outlets' sections.
- Run a French pass. Repeat the search with French subject vocabulary and the Language results filter set to French.
- Check audience and selling path. Confirm each candidate's Canadian audience and its ads.txt file before it joins the list.
How do you find French language equivalents of English seeds?
French Canadian publishers serve a readership of their own. Canadian Heritage's official languages statistics (opens in a new tab), from the 2021 Census, count 8,066,633 French-speaking people, 22.0 percent of Canada's population, including 84.1 percent of Quebec's population; 18.0 percent of Canadians are bilingual in English and French. A plan that stops at English lookalikes leaves that readership to chance.
| Route | How it works | Strength | Weakness |
|---|---|---|---|
| Language versions of bilingual sites | Follow a Canadian candidate's language switch or its hreflang alternate links to the French version | The French version covers the same subject by design | Only finds French pages of sites that already publish both languages |
| French subject vocabulary | Search the subject with the terms French Canadian writers use, not a word for word translation | Finds French first publishers with no English version | Needs a French speaking reviewer to choose and check the terms |
| French sections of national outlets | Seed with the French section's articles, not the whole outlet | Large, established inventory on the subject | A section can be thin while the outlet as a whole is broad |
| Francophone networks outside Quebec | Check member lists of minority language press networks | Reaches French readers in other provinces | Community papers cover places more than specialist subjects |
Google's guide to localized versions (opens in a new tab), last updated 21 September 2026, describes hreflang link elements in a page header that "tell Google all of the language and region variants of a page." A bilingual Canadian site that uses them hands the planner a direct path from an English article to its French counterpart. The French Canadian advertising guide covers telling a Canadian French site from one in France or Belgium.
How do you confirm a lookalike has a Canadian audience?
Three kinds of record speak to a Canadian audience, and each answers a narrower question than it seems to. The domain ending, the footer address and the country of incorporation are not among them. The Government of Canada's directories of Canadian companies (opens in a new tab) let a buyer check that a company is incorporated, which says where a business is registered, not where its readers are.
| Record | What it measures | Limit |
|---|---|---|
| Chrome UX Report country data | Popularity of an origin among Chrome users, with country values "inferred from users' IP addresses" | "Country dimensions are not available in the CrUX APIs", only in BigQuery, and small sites fall below an undisclosed threshold |
| Google Ads matched locations | Performance by "the locations where your ads appeared" | Google says these "could be users' physical locations or locations of interest" |
| Display & Video 360 Country dimension | Delivery by country, read beside the App/URL dimension for each site | Shows where a campaign's ads were delivered, not the site's whole readership |
| Business registry record | Where the publisher's company is incorporated | Says nothing about where its readers live |
The Chrome UX Report dimensions page (opens in a new tab) is the planning record; Google's geographic performance reports (opens in a new tab) and Display & Video 360's report dimensions (opens in a new tab) are the delivery record once a test runs. A lookalike with no country data yet is recorded as missing, as the small websites guide explains.
Should US seeds popular in Canada stay in the list?
Yes, when the evidence shows Canadian readers. Location targeting decides where ads reach people: Google Ads lets advertisers choose "entire countries, areas within a country like cities or territories, and even a radius around a location", per its location targeting help (opens in a new tab). A US site with a real Canadian audience delivers to Canadians under Canadian targeting, and dropping it for its address removes readers the client already values.
The review quadrant matters for subjects with national rules. A US seed popular in Canada that writes about US rebates, prices or regulations can confuse a Canadian reader beside an ad for a Canadian offer. Keep it if its coverage is general enough for the creative; otherwise let its Canadian lookalikes carry the subject. The US and Canada audience guide covers audience targeting across both markets.
How many Canadian lookalikes should a plan include?
The Canadian part of a lookalike list is sized in two directions: across languages and against the forecast. The brief sets the languages. Within them, the census figures above are context for whether a French list is needed, not a quota for its length. The forecast sets the size: Display & Video 360's Inventory Availability report (opens in a new tab) can be refined by targeting and inventory settings, so run it with Canada as the location and each language separately.
Before the Canadian lookalike list is approved
- Each US seed kept on the plan has Canadian audience evidence recorded beside it.
- Each Canadian lookalike is labeled with the seed it resembles and the articles that show the match.
- French lookalikes were found by a French pass, and each was read in French by a reviewer.
- The forecast was run for Canada with the English and French parts of the list separately.
- Sites with no country data are labeled as missing data, not as having no Canadian readers.
- Each site's ads.txt file was opened and its selling path recorded.
A short Canadian list is a finding, not a failure. When a subject has few Canadian specialists, the plan can say so and keep the US seeds with Canadian readers, rather than adding broad Canadian sites that cover the subject in passing. The programmatic media planning hub covers list size in general.

What does a Canadian lookalike search look like on a real brief?
Fictional example
A fictional air purifier maker selling across Canada
An unnamed maker of home air purifiers, selling across Canada, gives its agency two US seeds: a home air quality review site and an indoor allergy blog. The campaign runs nationally in English and Canadian French.
The planner describes the review site as in depth testing of purifiers and filters, with US retailer prices, and the allergy blog as practical advice for allergy sufferers at home, citing US health agencies. The Canadian descriptions swap in Canadian prices, retailers and health agencies. The English search finds a Canadian home technology review site and a home section of a national outlet; the French pass finds a Quebec home and renovation magazine with a regular air quality column and the French version of a bilingual Canadian health site, reached through its hreflang links.
Country data shows the US review site popular in Canada, so it stays, labeled as a seed with Canadian readers. The allergy blog has little Canadian popularity and stays a seed only. The plan lists the English and French lookalikes in separate parts, each sized against its own forecast for Canada.
Frequently asked questions
Is a Canadian edition of a US site a separate lookalike?
Treat it as its own entry when it publishes its own Canadian articles in its own section or subdomain. Seed and review that edition's pages, not the US home page. Check which ads.txt file covers it, since the specification places the file at the root domain, and confirm the edition's sellers match its owner.
Do Canadian lookalikes need to be Canadian owned?
Only if the brief requires it. Audience and subject decide whether a site fits a Canadian plan; ownership is a separate requirement some clients set. When it applies, check the publisher's company in the Canadian business registries and record the result, keeping it apart from the audience evidence.
What if a French counterpart covers a broader subject than the English seed?
Seed and judge it by the section that matches. A French home magazine with a regular air quality column can match an English air quality site through that column alone. Label it with the section and the matching articles, and keep the rest of the magazine out of the matching claim.
What if a US seed has no Canadian equivalent?
Say so in the plan. Keep the US seed if it has Canadian readers, and look for Canadian sites that cover the subject inside a broader section. If neither exists, the plan carries fewer Canadian sites for that subject, with the reason, rather than broad sites that match only loosely.
