# App Store Keyword Field Optimizer: Free 100-Character Cleaner

Source: https://asostudio.app/tools/keyword-field

Paste your App Store keyword field and get it back with duplicates, spaces and title words removed, counted live against Apple's 100-character limit. Free, no sign-up.

## What it does

Paste your keyword field. Get it back with nothing wasted, counted against Apple's 100 characters.

It runs in the browser. Nothing typed into it is uploaded, so a model cannot run it: the rules it applies are below, and they are the answer to the question the page is for.

## The rules it applies

- The field caps at 100 characters in App Store Connect, and everything past that is silently ignored.
- Single words separated by commas, with no spaces after the commas: a space is a character spent on nothing.
- Words already in the title or subtitle are removed, because Apple indexes those fields anyway and repeating a word buys nothing.
- Duplicates are removed, including close plural pairs: Apple matches "movie" and "movies" as one spend.
- Nothing typed into the tool leaves the browser.

## Frequently asked questions

### How long can the App Store keyword field be?
100 characters, and everything past that is silently ignored. The keyword field in App Store Connect caps at 100 characters. Apple indexes single words from it and combines them with the words in your title and subtitle, in any order, so the highest-value form is single words separated by commas with no spaces.

### Should I repeat words from my title in the keyword field?
No. Words in your title and subtitle are already indexed, and repeating one in the keyword field spends characters on a word Apple already has. That is the first thing this tool removes.

### Do I need plurals in the keyword field?
Usually not. Apple matches close plural forms of a word, so "movie" and "movies" are one spend, not two. The tool treats plural pairs as duplicates for the same reason.

### Is my keyword field uploaded anywhere?
No. The whole tool runs in your browser and nothing you type leaves the page.
