App Store keyword research without paid tools

Keyword research is the part of App Store Optimization that most developers overthink. The market is full of expensive tools that promise rank tracking, competitor intelligence, and magical keyword scores. In reality, you can build a strong keyword list for your iOS app without paying for any of them. It takes a bit of manual work, but the signal you get is often better than a dashboard full of estimates.

Start with the App Store search bar. Type the core word that describes your app and watch what Apple suggests. These suggestions come from real user queries, ordered by popularity. If you have a meditation app, type "meditation" and note every variation: meditation for sleep, meditation timer, guided meditation for anxiety. Each suggestion is a phrase people already search for. Repeat this with related words like mindfulness, breathing, and sleep sounds. Do it on both iPhone and iPad, because autocomplete can differ between devices.

Next, look at the apps that already rank for those terms. Open their listings and read the title, subtitle, and description. Apple gives you 30 characters for the title on iOS and 30 for the subtitle. Developers rarely waste that space, so the keywords they include are usually deliberate. You are not looking to copy them. You are looking for patterns. Are they using category words? Are they targeting specific use cases? Are they going broad or narrow? Write down every relevant term you see, then filter the list by how closely it matches what your app actually does.

Reviews are another free source of keyword ideas. Scroll through the reviews of competing apps and pay attention to the language users use. They will describe problems, features, and outcomes in ways you might not expect. Someone might call a budget app an "expense tracker" while the developer calls it a "finance manager." Both phrases could be useful. The words your potential users already use are the words most likely to convert.

Do not ignore the keyword field. Apple gives you 100 characters of hidden keywords. This is where you put terms you could not fit in the title or subtitle. Do not repeat words that already appear in the title or subtitle, because Apple does not give extra credit for repetition. Use commas without spaces to pack in as many relevant terms as possible. Every character matters, so choose carefully.

Once you have a list, group your keywords by intent. Some keywords describe what the app is, like "habit tracker." Others describe what the user wants, like "build better habits." A few describe the situation, like "stop procrastinating." A good metadata set mixes all three. The title should carry your strongest brand and category term. The subtitle should explain the main benefit. The keyword field should cover variations and long-tail phrases.

Now you need to turn that list into actual metadata. This is where AsoFast fits in. It gives you a single interface to draft titles, subtitles, keyword lists, and descriptions, all with live character counts. You can generate variations from your research, compare them side by side, and export the final set ready for App Store Connect. Because it runs locally, you can iterate without sending your app idea or competitor list to a third-party service.

After you publish, keep an eye on organic impressions. The App Store Connect analytics will show you which search terms bring traffic. Some will surprise you. That is the real feedback loop. Update your metadata every few weeks based on what you learn. Keyword research is not a one-time task. It is a habit.

Paid tools can save time when you manage many apps, but they are not required to get started. Free research gives you a sharper understanding of your market. Pair that with a disciplined writing process and a tool like AsoFast, and you can ship metadata that is grounded in real user language rather than guesswork.
