> Quick answer: Build a separate French campaign in Google Ads. Translate all copy within the 30-character headline and 90-character description limits. Match your landing page. Review with a native speaker. Use AI tools to generate accurate French copy that keeps your brand voice intact.
Why Translating Google Ads to French Requires a Different Campaign
Mixing languages in one campaign is a structural mistake. Keep French and English completely separate from campaign creation.
Don't mix languages in a single campaign
Google Ads expects all ad copy in a campaign to match its language targeting. Mixing French and English copy inside one campaign sends conflicting signals to the platform. Performance suffers. Keep them separate from the start.
French language targeting in Google Ads
Google Ads natively supports French as a campaign language. You can target French speakers globally or by region. France, Canada, Belgium, and Switzerland all have large French-speaking audiences with different cultural expectations.
Creating French campaigns for French-speaking audiences
Copy your existing English campaign structure. Then replace every headline, description, and extension with French copy. Do not translate line by line inside a live English campaign. Start fresh with the French version.
Step-by-Step. Translate Your Google Ad to French
Set language targeting to French when creating your campaign
Go to Campaign Settings in Google Ads. Under Languages, select French. This ensures your ads reach French-speaking users. Set this before writing a single word of copy.
Translate headlines and descriptions while respecting character limits
Per Google Ads Help, headlines allow up to 30 characters each. Descriptions allow up to 90 characters. These limits apply equally in French. French text runs 15.20% longer than English on average. Draft your French copy first, then trim to fit.
Ensure French ad copy matches your brand voice
Word-for-word translation sounds unnatural to French speakers. A native reviewer catches phrases that technically translate but feel flat or off-tone. Brand voice must stay consistent, in any language.
Check your landing page is translated to French
Your landing page must match your ad language. Sending a French-speaking user to an English page breaks trust immediately. It can also raise compliance issues under Google's editorial guidelines. Translate the full landing page before launching.
Review for editorial compliance and natural language
Per Google's Advertising Policies, all ads must meet high professional and editorial standards. This applies equally to French ads. Spelling errors, awkward grammar, or unclear phrasing will get ads disapproved. Read the copy aloud in French before publishing.
Key Considerations When Translating to French
Character limits are the same across all languages (headlines 30 chars, descriptions 90)
Per Google Ads documentation, the 30-character headline limit and 90-character description limit apply to every language, including French. There are no exceptions for translated content.
French text is often longer than English. Plan your spacing.
"Click here to learn more" becomes "Cliquez ici pour en savoir plus." That expansion is typical. Count characters during the drafting phase, not after. Build trimming time into your workflow.
Use native speakers or professional translation for natural tone
Machine translation handles structure. It misses idioms, register, and cultural cues. A French-native reviewer catches what automated tools cannot. That review step is not optional if you want ads that convert.
Google's editorial standards apply to translated ads
Google treats French ads with the same editorial scrutiny as English. Poor grammar, odd phrasing, or unclear messaging triggers disapprovals. Translated ads must read like native content, not like a direct conversion.
Avoid machine translation alone. Add cultural nuance.
French audiences respond strongly to tone. Formal French (vous) versus informal French (tu) is a key choice that changes how your ad feels. Decide upfront. Apply it consistently across every headline, description, and extension.
How to Speed Up Translation with AI Tools
Translating copy manually for every variation takes hours. AI tools cut that time significantly and keep voice consistent across assets.
Generate French ad copy from your brand profile once
Coinis Brand Profile stores your tone, product details, and audience context. Once set up, Coinis AI Copywriting generates French headlines and descriptions that already sound on-brand. No briefing a translator from scratch for every campaign.
Translate existing English copy in seconds
Coinis Revise includes AI Translate. Paste your existing ad copy, select French, and the tool returns a translated version that fits your brand voice. You still review it. But you start from a strong draft, not a blank page.
Create variations for A/B testing in French
Responsive search ads support up to 15 headlines and 4 descriptions. Coinis AI Copywriting generates multiple French headline options in one pass. Feed them into a responsive search ad and let Google test combinations automatically.
Maintain voice consistency across all French ad assets
Every French headline, description, and visual overlay can pull from the same Brand Profile. Tone stays consistent as you scale into new markets, even across multiple campaigns.
Common Translation Mistakes to Avoid
Word-for-word translation without cultural context
Literal translation kills engagement. Phrases that work in English often land awkwardly in French. Always check meaning in context, not just word accuracy.
Ignoring character limits when expanding translations
French naturally expands. A 28-character English headline becomes a 34-character French version. Write and count in French from the start. Do not translate a finished English ad and assume it fits.
Mixing formal and informal French register
Choose tu or vous before writing. Apply that choice consistently across every ad, landing page, and extension. Inconsistency signals low quality to French speakers immediately.
Not testing landing page experience in French
Run the full user journey yourself. Click the ad. Read the page. Complete the form. Anything that breaks in French breaks your campaign. Test it before spending budget.

Frequently Asked Questions
Can I translate my Google Ad into French without creating a new campaign?
No. Google Ads recommends separate campaigns per language. Mixing French and English copy inside one campaign can hurt relevance and performance. Build a dedicated French campaign from the start.
Do French Google Ads have different character limits than English ads?
No. Per Google Ads Help, headlines allow 30 characters and descriptions allow 90 characters in all languages, including French. French text typically runs 15-20% longer than English, so plan your copy carefully within those limits.
Can I use machine translation alone to create French Google Ads?
Machine translation helps with structure but misses cultural nuance and idiomatic tone. Google's editorial policies require ads to read naturally and use correct grammar. Always review machine-translated copy with a native French speaker before publishing.
Will Coinis publish my French ads directly to Google Ads?
Not yet. Coinis direct publishing supports Meta (Facebook and Instagram) today. Google Ads direct publishing is on the roadmap. You can use Coinis AI Copywriting and AI Translate to generate accurate French ad copy, then paste it into Google Ads manually.
