TL;DR: Google Ads does not auto-translate your ads. Write German copy manually, stay within 30-character headlines and 90-character descriptions, and plan for 20-35% longer text than your English original.
Translating a Google ad to German takes more than swapping words. Character limits are strict, and German text runs long.
Understand Google Ads Language Targeting
Language targeting determines who sees your ads, not the language your ad copy displays in.
What language targeting does
Per Google's Ads Help Center, language targeting shows your ads to users who interact with Google products in a chosen language. Set targeting to German and German-speaking users enter your funnel. Your copy still needs to be written in German.
Language targeting vs. campaign language
Two different settings control language in Google Ads. Language targeting controls audience reach. The language of your ad copy is your responsibility. Align both for a German campaign to work correctly.
Why you need separate ad versions
Google Ads does not auto-translate your ads. You must create a separate German ad version with its own headlines and descriptions.
German as a target language
German uses standard single-width character counting in Google Ads. Each character counts as one. That matters when German compound words eat through your 30-character headline limit fast.
Step-by-Step: Translate Your Google Ad to German
These six steps take you from a working English campaign to a ready-to-launch German version.
Step 1: Set campaign language targeting to German
Go to campaign settings. Find the "Languages" field. Add German. This tells Google to show your ads to German-speaking users across Search, Display, and Gmail.
Step 2: Duplicate your existing ads for the German version
Don't overwrite your English ads. Create a new ad group. Duplicate your existing ads as a base. Edit the copy from there.
Step 3: Write or translate headlines (max 30 characters each)
Each headline allows 30 characters. German words run long. "Jetzt kaufen" (12 chars) works fine. "Kaufen Sie jetzt sofort ein" (27 chars) leaves almost no room. Write short, punchy phrases.
Step 4: Write or translate descriptions (max 90 characters)
Per Google's Ads Help Center, description limits are 90 characters, consistent across all languages. German translations push against that ceiling quickly.
Step 5: Plan for 20-35% text expansion
German translations of English copy typically run 20-35% longer in character count. Shorten your English source before you translate, or rework the German phrasing to stay tight.
Step 6: Preview your ad before launch
Use the Google Ads ad preview tool before publishing. Check that headlines display correctly. Confirm no copy gets cut off.
Key Translation Challenges for German
German localization is harder than most languages for paid ad copy.
Character limits and compound words
German builds meaning through long compound nouns. One German word can do the work of two or three English words and still run past 20 characters. That pattern hits every headline you write.
Preserving brand voice
Literal translation often kills the hook. "Save big today" becomes "Sparen Sie heute viel" in German. Technically accurate. Flat in tone. The German version needs the same urgency, just in German rhythm.
Using AI to speed up localization
AI tools can translate and refit copy to character limits at the same time. Coinis Revise includes AI Translate for exactly this. It adapts your copy to fit within target-language constraints without losing the core message. Pair it with AI Copywriting to rebuild headlines that land hard in German.
Common errors to avoid
Don't over-translate. Keep the marketing intent sharp. Check your formality level ("du" vs. "Sie") against your brand voice. Confirm your value proposition still lands after translation.
Why Manual Translation Matters (Google Ads Has No Auto-Translate)
Google Ads has no auto-translate feature. Google's own documentation confirms this. You must write German copy yourself, or use a dedicated translation workflow.
Cultural and legal relevance
DACH markets (Germany, Austria, Switzerland) have specific consumer expectations. German advertising law also has nuances. Literally translated copy often feels generic, off-brand, or misleading. A native review step matters.
How Coinis Revise AI Translate helps
Coinis Revise is an AI creative editor. Its AI Translate capability adapts your ad copy into German and refits it to character limits automatically. Coinis does not publish directly to Google Ads today. But it handles the translation and creative work before you upload to Google Ads. That saves significant time when you're managing multiple ad variants.
Next Steps: Launch Your German Campaign
Setup is done. Now focus on performance.
Review language targeting settings
After loading your German ad versions, confirm language targeting is set correctly at the campaign level. Double-check bid adjustments if you're entering a new market.
Monitor performance by language
Keep German and English campaigns separate. That gives you clean data to compare performance across languages.
Use Coinis to refresh your creative if performance dips
Translation is not a one-time task. If CTR drops after a few weeks, revisit the German copy. Use Coinis Revise to generate variants quickly and test new angles.
