How to Optimize Your App Store Keywords and Metadata — and the Best Free Tool to Help You

When it comes to App Store Optimization (ASO), choosing the right keywords and perfecting your app metadata can be the difference between getting discovered — or getting buried.

In this guide, we’ll walk you through why keyword optimization matters, how to craft better titles, subtitles, and keyword lists, and how to use the free App Store Keyword Optimization Tool to make the process faster and easier.

Why Keyword Optimization is Critical for App Success

Every word you choose in your App Store title, subtitle, and keywords field affects how your app ranks in search results.

Good metadata directly improves your app’s visibility, ranking, and ultimately, downloads.

Optimizing your App Store metadata helps you:

• Reach a wider audience searching for related terms

• Increase organic downloads without spending on ads

• Target niche audiences with specific keywords

• Improve search rankings in multiple countries and languages

But manually managing all this metadata — across many languages — can quickly become confusing.

That’s where the Free App Store ASO Keyword Optimization Tool comes in.

How to Optimize Your Keywords and Metadata with This Tool

Here’s a step-by-step guide to making the most out of appkeywords.pro:

1. Fill In Your Title, Subtitle, and Keywords

• For each locale (like en-US, es-ES, de-DE), you’ll see fields for Title, Subtitle, and Keywords.

• The tool shows you character limits in real-time (30 for Title/Subtitles, 100 for Keywords).

• Stay within the limits to avoid App Store rejections.

2. Press “Optimize” to Clean Your Keywords

• Hit the Optimize button next to the Keywords field.

• The tool automatically:

• Normalizes commas from different languages (Arabic, Japanese, Chinese, etc.)

• Replaces spaces with commas

• Trims extra commas

• Highlights duplicate or repeated keywords

➔ Blue bubbles mean good, unique keywords.

➔ Red bubbles flag keywords repeated in your title, subtitle, or primary locale (en-US).

• Click a bubble to quickly remove a keyword.

3. Autosave and Local Storage

• Autosave is enabled by default.

• Your inputs are automatically saved in your browser, even if you close the page.

• Nothing is uploaded or stored externally — your data stays 100% private.

4. Import or Export Your Metadata (Optional)

• Use Import from JSON to load a previously saved metadata set.

• Use Export to JSON to download your current metadata as a file you can reuse or archive.

• JSON format is perfect for large apps managing multiple languages.

5. Clear All Data (Optional)

• If you want to start fresh, click Clear All Data.

• This wipes all fields and resets autosaved values.

Pro Tips for Better ASO

• Focus on high-intent keywords — words users actually search for.

• Avoid repeating the same keyword in title, subtitle, and keyword field unless absolutely necessary.

• Use all 100 characters in the keywords field — every character counts.

• Localize metadata for every major market you target.

• Regularly update your metadata based on seasonal trends or performance changes.
