# 100 characters, not one wasted.

> Uptika's keyword field builder fills the App Store's 100-character keyword field for you: it drops words already in the name or subtitle and filler words, splits phrases into words, removes repeats and lists the rest by popularity, separated by commas.

The keyword field builder fills the App Store's hidden keyword field with words your name and subtitle do not already cover, in popularity order, counting bytes as it goes.

## What do you get?

- **No repeats**: A word in your name or subtitle stays out of the field; the store already reads it. Multi-word phrases are split and each word goes in once.
- **Characters and bytes**: App Store Connect counts the field as 100 bytes, and accented letters take two bytes each in UTF-8. The counter shows both and warns when you go over.
- **Before and after**: The current field next to the new one: words added and removed, and how many tracked keywords are covered now and after.
- **Plain-letter spellings**: For Turkish storefronts you can add plain-letter spellings of your top three words, for searches typed without ç, ğ, ı, ö, ş or ü.
- **Keyword density for Google Play**: Google Play has no hidden field, so the page turns into a keyword density table: how often each word appears in the title, short and full description; 3–5 is good, more than 8 can count as stuffing.

## How does it work?

1. **Your keywords are ready**: Your tracked keywords arrive with their popularity; add extra words if you like.
2. **The field is built**: Uptika splits words, drops repeats and what the name and subtitle cover, and lines up the rest by popularity into 100 characters.
3. **Copy and paste**: Copy the result and paste it into the keyword field of your next version in App Store Connect. Uptika does not send anything to the store.

## Which plan includes it?

Free: The keyword field builder is on every plan. To fill it from more keywords, Starter tracks 100, from $29 a month.

## Questions

### Should I put spaces between keywords?

No. A space after a comma costs a character. The builder separates words with commas and no spaces.

### How does it know my current field?

With App Store Connect connected it reads the live field. Without it the field is unknown and you type your name and subtitle by hand.

### Is it free?

Yes, on every plan. The words come from your tracked keywords; Free tracks 10.

### Does it work for Google Play?

Google Play has no keyword field. There the same page shows keyword density and whether a word appears in the first three lines.
