Write each responsive search ad asset in its own field above. The counter checks every headline, description, and display path independently, so a longer description is not compared with a headline limit.
Responsive Search Ad Character Limits
| Asset | Limit |
|---|---|
| Headline | 30 characters each; 3–15 headlines |
| Description | 90 characters each; 2–4 descriptions |
| Display path | 15 characters each; 2 optional paths |

How to Check Your Ad Copy
- Fill the three initial headline fields and two description fields.
- Use Add headline or Add description for extra variants.
- Add optional display paths separately from the final destination URL.
- Review any asset marked over its limit. Extra characters remain visible so you can edit them.
- Copy the labeled draft or download it as TXT, then transfer each asset into Google Ads.
Drafts stay in the current tab and are not uploaded or saved by this tool. Copy or download your work before leaving or reloading.
Counting Double-Width Characters
Google counts double-width characters as two. This tool uses Unicode width data to account for text such as Chinese, Japanese, Korean, and fullwidth forms. “Shop 東京” uses nine character units: five for the Latin text and space, plus four for the two Japanese characters.
Do spaces and punctuation count?
Yes. “Free Shipping & Returns” uses 23 characters, including spaces and the ampersand. The count updates per field.
Does passing the length check mean my ad is approved?
No. Length is one requirement. Review the final preview, destination, dynamic text, emoji, and policy requirements in Google Ads. The tool does not submit ads or check approval status.
Will every headline appear together?
No. Google combines eligible assets for the available ad layout. Write each asset to make sense independently and review pinning options inside Google Ads when a particular message must appear.
