How Apple's keyword indexing works

Title (30 chars)

Carries the most weight for search ranking. Primary keywords — the ones you most want to rank for — should be here.

Subtitle (30 chars)

Second-highest weight. Use secondary keywords that didn't fit in the title. Avoid repeating title words.

Keyword field (100 chars)

Comma-separated. No spaces around commas needed — commas don't count toward the 100-char limit. No repeats from title or subtitle.

Duplicates waste space

Apple only indexes a word once. A word in your title AND keyword field wastes 100-char keyword field space that could be a new keyword.
