How Does Google Ads Count Characters?
Spaces, letters, numbers, and punctuation contribute to text limits. Google also specifies that double-width characters, such as many Chinese, Japanese, and Korean characters, count as two. This tool counts Unicode characters and applies double-width weighting rather than relying on JavaScript's basic string length.
For uncommon emoji sequences, special formatting, automatically inserted text, and editorial restrictions, always check the final text in Google Ads itself. A passing character count does not guarantee ad approval.
Tips for Writing Responsive Search Ads
Make headlines useful on their own, avoid repeating the same message across assets, and write descriptions that add meaningful information. Google can assemble the assets in different combinations, so do not rely on a particular ordering.
