Language strategy comes first. This article covers execution: when you advertise in French and Hebrew, how should you structure campaigns, test and decide?
One language, one complete journey
Each language must stay consistent throughout: ad, landing page, form, confirmation message and follow-up call.
Include the language in campaign and ad names (_FR, _HE). Without it, language-level analysis is unreliable.
On Meta: let the creative select the audience
-
Language targeting excludes French speakers using their phones in Hebrew or English. A French creative with broad delivery qualifies its audience more effectively
-
To compare languages, test the same concept and offer. Comparing an established French winner with a new Hebrew creative proves little
-
Hebrew imperatives are gendered: choose plural, neutral wording or separate versions
-
For bicultural families, a Hebrew video with French subtitles is worth testing
On Google: ad language becomes the lever
-
Google identifies the languages a user understands from several signals, including their search language and settings
-
Google announced that from September 2026, campaign-level language settings would be removed for Search campaigns: matching would use the language of the ads themselves. Writing ads in the right language becomes your main language-targeting tool
-
Separate ad groups or campaigns by keyword language to keep performance analysis clear
-
Cover Hebrew spelling variants and transliterated French brand names
Measure by language all the way to the customer
-
Include language in your UTM parameters and a CRM field
-
Compare cost per qualified lead and cost per customer, not just CTR or CPM
-
One language may produce cheaper leads but more expensive customers. Cost per customer decides
-
Wait for enough conversions per version before drawing conclusions
The most common mistakes
-
unreviewed machine translation,
-
the same landing page for both languages,
-
a decision based on the first week’s CPM,
-
a sales follow-up in a different language from the ad
