How to fill the App Store keyword field.

1. Separate with commas, no spaces

Write "habit,tracker,routine,goals", not "habit, tracker, routine, goals". The spaces cost you three characters here and more in a full field.

2. Never repeat a word

Apple combines words from your name, subtitle and keyword field. If "tracker" is in your subtitle, it does nothing in the keyword field. Each word only needs to appear once across all three.

3. Use single words, not phrases

Apple matches "habit tracker" if you have "habit" and "tracker" anywhere in the indexed fields. Writing the phrase adds nothing but the extra characters.

4. Skip what Apple adds for you

Some words are wasted in the keyword field:

• Your app name and your company name
• The category name, and the word "app"
• Plurals when you already have the singular, in English
• Competitor brand names, which can get your update rejected

5. Localize per market

Every locale has its own keyword field, and some storefronts index more than one locale. The US storefront, for example, also searches the Spanish (Mexico) listing, which gives you another 100 characters for English-speaking users.

Translate keywords by what people search in each market, not word by word.

6. Measure, then change

Track your rank for each keyword for a few weeks after an update. Keep the words that brought you into the top results and replace the ones that did not.
