App Store Keyword Field Optimizer
Pack your iOS keyword field to the 100-character limit. We strip duplicates, space-stealing commas, and words Apple already indexes from your title or subtitle.
Words here are auto-indexed by Apple, so we drop them from your keyword field.
Same deal. Subtitle words are already indexed.
One per line, or comma-separated. Multi-word phrases stay together.
Strips Title Overlap
Words in your app name and subtitle are auto-indexed. We drop them so you do not burn characters twice.
Greedy 100-Char Packer
Walks your list in order, fits every keyword that will fit, and tells you exactly why the rest did not.
Comma-Only Separator
No spaces after commas. That is Apple's rule, and spaces cost you searchable characters.
How it works
Optional but recommended. Lets the optimizer skip words Apple already indexes.
One keyword per line, or comma-separated. Multi-word phrases stay intact.
Get a ready-to-paste, comma-separated string that fits in 100 characters.
