App Metadata Optimization for iOS
Your iOS metadata is a small, high-leverage budget. Spend it deliberately.
The three fields
Title (up to 30 chars) — your brand plus one or two top keywords. Subtitle (up to 30 chars) — a second cluster of high-value terms. Keyword field (100 chars, hidden) — everything else, comma-separated, no spaces, no repeats of title/subtitle words.
Don't waste characters
Apple combines your fields, so never repeat a word across them. Skip plurals Apple already handles, drop stop-words, and don't include your category name if it's implied.
