How to Write App Store Ad Copy (Listing Text and Apple Search Ads Creative)
To write App Store ad copy, treat your listing as the landing page for every ad: write a keyword-aware title and subtitle within Apple's character limits, lead the promotional text with one specific benefit, make the first screenshots carry the pitch, and create custom product pages for the audiences or keywords you advertise to. Infinall AI drafts copy options and creative for your review; you enter the final text in App Store Connect and manage any Apple Search Ads campaign yourself.
On the App Store, much of your 'ad copy' is your listing itself. Apple Search Ads can reuse your product page metadata, so the title, subtitle, screenshots and description do the persuading for paid and organic traffic alike. Writing that copy takes more constraint than creativity: tight character limits, indexing considerations and Apple's review guidelines all apply. This guide covers the mechanics in App Store Connect and Apple's advertising platform, with a short Google Play note, then explains where Infinall AI can help draft and compare options. Limits and features change, so confirm current figures in Apple's and Google's documentation. Infinall AI does not submit your listing, place media or guarantee App Review approval.
How to Write App Store Ad Copy (Listing Text and Apple Search Ads Creative)
Define one audience, one promise and your priority keywords
Before writing, decide who the app is for, the single outcome it delivers and the 10 to 20 phrases that audience would search to find an app like yours. Check the live listings of competing apps to see how they describe the category; Infinall AI's Ad Spy can help you browse competitor ads, and App Store search suggestions show phrases people actually type. Rank the keywords by relevance first and difficulty second, because a relevant mid-volume term usually beats an irrelevant big one.
Write the title and subtitle within the character limits
In App Store Connect, the app name and subtitle are each limited to 30 characters on the App Store at the time of writing (verify current limits). Use the name for your brand plus one core descriptor if there is room, and use the subtitle for the clearest benefit written in plain words. Do not repeat words across name, subtitle and keyword field, since Apple indexes them together and repetition wastes space. Avoid unverifiable superlatives such as 'best' or 'number one', and never reference other brands or prices that Apple's guidelines prohibit.
Fill the keyword field and write the promotional text
The keyword field in App Store Connect holds up to 100 characters of comma-separated terms that users do not see. Use single words without spaces after the commas, skip plurals if the singular is indexed, and leave out terms already in your name and subtitle. Promotional text (up to 170 characters) appears above the description and can be edited without submitting a new app version, so use it for a current benefit, a seasonal message or a launch offer you can honestly stand behind. The longer description does not directly drive App Store search, so write it for readers, with the strongest benefit first.
Let the first screenshots and preview video carry the headline
Most people see only the first few screenshots in search results and on your product page, so treat them as ad frames. Give each screenshot one short caption stating a benefit (not a feature name), show the real interface, and order them as a story: the main outcome first, then supporting features. Keep text large enough to read at thumbnail size and localise captions if you target several languages. An app preview video should show the core action within the first seconds. Infinall AI can generate caption options and image drafts for these frames, which land in an Approval Queue for you to edit before export.
Create custom product pages for the audiences you advertise to
In App Store Connect, create custom product pages with their own screenshots, promotional text and preview videos, each with its own URL. Match each page to a specific ad group or keyword theme, for example one page for budgeting features and another for investing, so someone who searched for a particular need sees copy that answers it. In Apple Search Ads Advanced you can choose which product page an ad uses, so check the options available in the current interface. Keep the claims on each page consistent with what the app actually does.
Submit, then test and refine copy using store and ad data
Submit the metadata for App Review, making sure screenshots, description and any claims match the app's current behaviour. Once live, compare conversion from page views to downloads in App Store Connect analytics and, if you advertise, tap-through and install rates in Apple Search Ads by keyword. Change one element at a time (the first screenshot, the subtitle, the promotional text) so you can tell what moved the numbers, and use product page optimisation tests where available. If you also publish on Google Play, note that its title is 30 characters and its short description is 80, with the full description indexed for search; the writing approach is similar but the fields differ.
Frequently asked questions
What is the difference between App Store listing copy and Apple Search Ads copy?
With Apple's search ads, the ad format pulls from your App Store product page, so your listing text and screenshots effectively are the ad creative, and you choose which custom product page the ad shows. That means you do not write a separate headline for each ad the way you would on Google Search. The copy you control is the metadata and custom product pages in App Store Connect.
Can Infinall AI publish my App Store listing or run Apple Search Ads?
No. Infinall AI drafts and reviews copy options, caption ideas and creative for your approval, but you paste the final text into App Store Connect and run any Apple Search Ads campaign yourself. It does not submit listings, place media, manage live ad spend or guarantee App Review approval, and it does not replace a review against Apple's guidelines. The Free plan is $0 with 1,000 credits/month; Pro is $30/month.
How often should I change my app's title and subtitle?
Changing the name or subtitle requires a new app version submission, and each change can shift the keywords you rank for, so avoid frequent rewrites. Make one deliberate change, give it enough time to produce meaningful data, and keep a record of what you changed and when. Promotional text is different: it can be updated without a new version, which makes it a safer place to test messaging.
