App Metadata Optimization: Field-by-Field Audit Guide

App metadata helps people find your app and decide whether it is useful to them. Review the name, short copy, keywords and description together. The wording should describe the current app, fit each field and make sense without a list of search terms attached.

This guide walks through the text fields on the App Store and Google Play. Use it to prepare a launch or review an existing listing. For the wider process, see the app store optimization guide.

Start with the fields each store provides

Both stores have a title and full description, but their other fields differ. Apple provides a subtitle, hidden keywords and promotional text. Google Play has an 80-character short description and no separate keyword field.

Apple's search guidance names the title, subtitle, keywords and category among its relevance signals. Its field reference also says the description is used for web search results. Keep those uses separate, and write the description to explain the app clearly.

Apple's marketing guidance calls the keyword allowance 100 characters, while its field reference specifies 100 bytes. Accented and non-Latin characters can use multiple UTF-8 bytes. Check both counts and validate the final text in App Store Connect.

Make the title easy to understand

A title needs to identify your app at a glance. If the brand name does not explain its purpose, add a short task phrase. A fictional example such as “FitTrack: Workout Planner” tells a reader more than “FitTrack” alone.

Try a few versions and read them at phone size. A colon or dash can separate the brand from the description; choose whichever reads best. There is no published ranking bonus for a particular separator.

• Keep the name within 30 characters and check how it appears in a search result.
• Choose a relevant phrase that describes the current app.
• Remove decorative symbols, repeated keywords and claims you cannot support.
• Keep enough of the brand name for existing users to recognize it.

A crowded title such as “Photo Editor Collage Filters Camera Beauty” is hard to read and may fail store rules. A generic name such as “Photo App” gives people little to remember. Aim for a clear middle ground.

AI metadata generation can help you explore alternatives from an accurate app brief. Review the wording yourself; a generated title is a draft, not a prediction of search performance.

Use short copy to add something useful

Apple subtitle: 30 characters

The subtitle can explain another important task or benefit. Avoid repeating the full title. For example, a fictional notes app might pair “Fieldbook: Notes” with “Organize ideas and projects,” if those features are available.

Apple's product-page guidance explains the role of the subtitle. Choose wording that helps a reader understand the app, then check keyword relevance and length.

Our listing-update study cannot reliably measure how many apps omit subtitles because its collected fields do not establish subtitle coverage. Check your own live listing directly.

Google Play short description: 80 characters

Use the extra room to explain the main task in one natural sentence. For a workout app, an illustrative draft is “Track workouts and build a plan that fits your week.” Add a feature such as AI coaching only if the app actually offers it.

Read the title and short description together. If they repeat the same idea, use the short description to answer the next question: who is the app for, what can they do, or what makes that task easier?

Choose Apple keywords deliberately

The keyword field is hidden from visitors. Use it for relevant terms that are not already covered by the app name, subtitle or category. Separate entries with commas and omit spaces after those commas. Apple allows spaces within keyword phrases.

For a budgeting app, a candidate list might be expense,savings,bills,receipt. This is an example of formatting, not a recommendation for every finance app. The right terms depend on the app's features and the results in its target storefront.

1. Start with real tasks. Write down what people can do in the app and how they describe those needs.
2. Inspect the search results. Check whether the leading apps serve the same purpose as yours.
3. Use research scores carefully. Record the source, country and date. A popularity estimate is not necessarily a count of searches; an unavailable value does not mean zero demand.
4. Remove duplicates. Apple advises against including plural forms of words already in the field. Review the appropriate phrasing for each language.
5. Validate before saving. Check the allowance and remove unrelated or unauthorized terms. You do not need to fill every available byte.

Keep the research in a small worksheet so you can explain why you chose each term. The keyword selection guide walks through that process. Longer phrases can be useful, but their actual competition still needs checking.

Write a description people can skim

Both stores allow up to 4,000 characters. That is a limit, not a target. Start with what the app does, explain its main features and make account, device or payment requirements clear.

App Store description

Focus on the decision a visitor needs to make. Give the main benefit in the opening, then show how the app delivers it. Short paragraphs and a few useful feature groups are easier to scan than a long catalogue.

Specific wording usually helps more than a grand promise. “Save a shopping list and share it with your household” tells readers what to expect. “Transform your life with effortless organization” leaves the task unclear.

Google Play description

Use the language of your app's tasks naturally throughout the explanation. Google's listing guidance asks for everyday language and warns against repetitive or irrelevant word blocks. It does not give an ideal keyword-density percentage.

A useful structure is:

1. Opening: explain the main task and who needs it.
2. Features: group related actions and describe what each helps the user do.
3. Requirements: state important account, subscription, device or connection needs.
4. Next step: explain how someone can begin.

Keep claims specific and supportable. Google's metadata policy and listing guidance cover misleading claims and other restrictions. Do not add user counts, awards or testimonials simply because a template asks for social proof.

Describe the actual changes in release notes

Replace “Bug fixes and improvements” with details that matter to users. For example, “Shared lists now stay available offline” explains a new capability. Only use that sentence if the release delivers it.

Lead with the most useful change, then mention other relevant improvements or fixes. Avoid promising features that are not ready. There is no need to fill the field with search terms.

Google's release guide specifies 500 characters per language. Apple allows 4,000. If you use batch updates, check the app, locales and approved text before sending, then verify the published result.

Review each language in context

Localizing a listing involves more than translating words. The task needs to be useful in that market, the wording needs to sound natural and the screenshots need to match the experience after installation.

• Research local phrases instead of assuming a direct English translation is the right keyword.
• Give a fluent reviewer the source copy, screenshots and product terminology.
• Rewrite text that no longer fits rather than cutting it mid-word.
• State any limits on languages supported inside the app.
• Assign someone to update the translations when the product changes.

AppDrift metadata translation prepares drafts in 60+ languages. It does not replace local research or human review. AI work uses tokens; check the quoted cost for the selected job.

For implementation, use the localization guide. To choose a first market and measure the result, see how to measure localization and installs.

A short metadata review checklist

• Can a new reader explain what the app does from the title and short copy?
• Does every claim match the current app, including paid features and language support?
• Do the final fields pass the store's limits, and do they look readable in previews?
• Are keywords relevant, researched in the right country and free of unnecessary repetition?
• Does the description explain the main task and its requirements?
• Do release notes and translations match the version being submitted?

Correct factual errors first. Then choose one meaningful wording change and save the old version, country, dates and traffic source. Store consoles show visits and downloads; AppDrift's listing tools help you prepare and maintain the text. A rank change and a download change answer different questions.

Review metadata when the app changes, users reveal confusion or your search research points to a better phrase. A fixed editing schedule does not guarantee better rankings. If discovery is still weak, use the download-growth planning guide to check the wider problem.

Frequently asked questions

How often should I update my app metadata?

Update inaccurate text promptly. Review the rest when features, requirements, audience needs or relevant search terms change. Save a baseline and allow enough traffic to assess the change; there is no universal editing or reindexing timetable.

Can I use the same metadata for iOS and Android?

You can reuse accurate app facts and suitable wording, but adapt them to each store. Apple has a subtitle and keyword field; Google Play has a longer short description and no keyword field. Validate every final field separately.

What's the fastest way to optimize metadata for multiple locales?

Keep source copy, terminology and reviewer decisions together. AI can help prepare drafts, but each language still needs review and final field checks.

Should I include competitor names in my keyword field?

No. Apple advises against competing app names and unauthorized third-party terms. Choose relevant words that describe your own app.

Do release notes actually affect rankings?

Use release notes to explain the changes in a version. They are not a confirmed keyword-ranking field. Keep the App Store and Google Play allowances separate.
