How limitpad counts
Each field is counted separately, including spaces and commas. Apple measures keywords in bytes, not characters: plain English letters take 1 byte each, accented letters 2 and Chinese, Japanese or Korean characters 3, so the keyword field holds fewer characters in those languages.
Tips
- Don’t repeat words from your app name in the keyword field. Apple already indexes them.
- Use commas without spaces between keywords to save characters.
