## Which fields affect App Store search

App Store search uses three fields: the app name, the subtitle, and the keyword field. The promotional text, description, and What’s New notes are for people deciding whether to download, not for search.

- **Name and subtitle:**  put your most important search words here, since customers see them too. Repeating a word between the two is allowed, but it uses visible space without matching any new searches.
- **Keywords:**  add different words that didn’t fit in the name or subtitle. Repeating name or subtitle words here only spends bytes.
- **Promotional text, description, and What’s New:**  write for people. Repeating words is fine; packing in keywords doesn’t help search and makes the page harder to read.

## How to use the keyword field well

1. Separate terms with commas and no spaces: timer,remote,group photo . Spaces inside a phrase are fine.
2. Leave out words already in your app name or subtitle. Both are searchable, so repeating them spends bytes for nothing.
3. Skip duplicates, plurals of words you already include, the word “app”, and names of categories.
4. Prefer single words over long phrases that repeat the same word.

Apple documents these limits in the [App information](https://developer.apple.com/help/app-store-connect/reference/app-information/app-information)  and [platform version information](https://developer.apple.com/help/app-store-connect/reference/app-information/platform-version-information)  references, and gives keyword advice on its [product page guide](https://developer.apple.com/app-store/product-page/) .

## Frequently asked questions

### What are the App Store character limits?

The app name and subtitle can each be up to 30 characters, promotional text up to 170, and the description and What’s New notes up to 4,000. The keyword field allows 100 bytes.

### Why are keywords counted in bytes?

App Store Connect limits the keyword field to 100 bytes, not characters. Letters such as ğ, é, or ü take two bytes, and many Chinese, Japanese, and Korean characters take three, so localized keyword lists fit fewer characters.

### Should I put spaces after commas in App Store keywords?

No. Apple recommends separating keywords with commas and no spaces. Each space is a byte you could spend on another keyword. Spaces inside a phrase, such as photo editor, are fine.

### Does the App Store description affect search?

No. App Store search uses the app name, subtitle, and keyword field. The description and promotional text are for people deciding whether to download, so write them to read naturally rather than repeating keywords.

### Should keywords repeat words from my app name or subtitle?

Usually not. The app name and subtitle are already searchable, so repeating their words in the keyword field uses bytes without adding new search terms.

### Does this tool upload my App Store text?

No. Counting and keyword checks run in your browser. The text is not uploaded, saved, or sent to a server.
