Free App Store Keyword Tool: What to Check First

A free App Store keyword tool is useful when it helps you answer one question: is this keyword worth using in metadata?

That sounds simple, but it is where a lot of ASO work goes wrong. A keyword can sound relevant and still have no demand. It can have demand and still be impossible to rank for. It can rank well in one country and do nothing in another.

So before you edit your app name, subtitle, or 100-character keyword field, use a keyword checker to narrow the list. You are not trying to build the perfect keyword universe. You are trying to find a small set of searches that deserve a real test.

If you want to check a term while reading, open the free App Store keyword checker. Then use the steps below to decide what the result means.

Start with a keyword that matches the app

The first filter is relevance. If the searcher would not be happy to land on your App Store page, the keyword is weak even if the numbers look good.

Good seed keywords usually come from:

• The main job your app does.
• The words users use in reviews or support messages.
• App Store autocomplete suggestions.
• Competitor titles and subtitles.
• Problems users are trying to solve.

For a habit app, "habit tracker", "daily routine", and "streak counter" are natural starting points. "Productivity" might have more demand, but it is broader and harder to satisfy. A broad keyword usually needs stronger ratings, stronger screenshots, and more authority before it works.

Use the free tool to test the obvious terms first. If the first result looks too competitive, move one level more specific.

Check demand before spending metadata space

The App Store keyword field is small. Your title and subtitle are only 30 characters each. That means every word has to earn its spot.

A keyword with no demand is not automatically useless, but it should not take your best metadata space. Low-demand terms can work when they are precise, local, or tied to a high-value user. For most apps, though, the first keyword set should include terms with enough search behavior to matter.

When you check demand, avoid reading one number in isolation. Ask:

• Is this term searched in the country I care about?
• Is demand high enough to justify using visible metadata?
• Is the phrase too broad for my current app strength?
• Does it describe a user with buying or download intent?

The useful keyword is rarely the biggest term on the list. It is the term where demand, relevance, and ranking difficulty meet.

Read difficulty as a reality check

Difficulty tells you how hard the current result page looks. It should slow you down before you chase a glamorous keyword.

Look at the apps already ranking. If the top results are established brands with thousands of ratings, strong screenshots, and exact keyword matches in their visible metadata, you need a reason to compete. That reason might be a sharper niche, a better product page, a country where the results are weaker, or paid data showing that the search converts.

For newer apps, the early wins often come from keywords with one of these patterns:

• Smaller apps already rank in the top results.
• The top apps do not use the phrase clearly in title or subtitle.
• The search intent is specific and your screenshots answer it well.
• The keyword is stronger in a country with less competition.

This is where a keyword finder should save you time. It should help you avoid spending a release on a keyword that had no realistic path.

Compare countries before choosing the final keyword

App Store search is country-specific. A keyword can be attractive in the United States and weak in Canada, the United Kingdom, Australia, France, or Germany. Even when the language is the same, the result page can change.

When you have a shortlist, check the same keyword in more than one country. You are looking for gaps:

• Countries where demand exists but difficulty is lower.
• Countries where different competitors rank.
• Countries where a localized keyword is stronger than the English term.
• Countries where your app category seems less crowded.

This matters because App Store metadata localization can give you more keyword surface area. A country-level keyword check helps you decide where that work is worth doing first.

Use competitors to understand search intent

The best free App Store keyword tools do more than show a score. They help you read the result page.

For each promising keyword, open the top ranking apps and check:

• Their app names and subtitles.
• Their first three screenshots.
• Rating count and average rating.
• Pricing and monetization.
• Whether the promise matches the search.

If every top app is a direct answer to the query and your app is only loosely related, skip the keyword. If several top apps feel generic, outdated, or poorly matched, you may have room.

Competitor research is not about copying metadata. It is about seeing what Google would call search intent, but inside the App Store: what the user probably expects when they type that phrase.

Turn the result into a metadata decision

After you check a keyword, decide where it belongs.

Do not repeat the same word across the title, subtitle, and keyword field. Apple can combine words across indexed fields, so repeated terms often waste character space. Use the strongest visible fields for the clearest promise, then use the keyword field to add supporting words.

For the full workflow, read the App Store keyword research guide. If you want the deeper product workflow after the free check, AppSprint ASO also has keyword research, rank tracking, and a metadata editor in the macOS app.

Track the keyword after you publish

A keyword check is only the first step. After you update metadata, give Apple time to reindex, then track whether the keyword actually moves.

Watch:

• Ranking position by country.
• Impressions from App Store search.
• Product page views.
• Conversion rate from product page view to download.
• Trial, subscription, or revenue signal if you have it.

If a keyword improves rank but does not bring downloads, the search may be weak or the product page may not match the promise. If impressions rise but conversion drops, your screenshots or subtitle may be attracting the wrong searcher. If ranking improves slowly, keep the keyword long enough to learn before replacing it.

The point is not to update metadata every week. The point is to keep a short feedback loop: research, edit, wait, measure, and replace the weak terms.

A simple free keyword-tool routine

Use this routine when you do not have a dedicated ASO team:

1. Write 10 seed keywords.
2. Check each keyword in your main country.
3. Remove terms with weak relevance.
4. Save terms with demand and manageable difficulty.
5. Check the best terms in two more countries.
6. Inspect the top ranking apps for the final shortlist.
7. Put the best phrase in title or subtitle.
8. Put supporting words in the keyword field.
9. Track rankings and search downloads after indexing.

That is enough to avoid the most common ASO mistake: choosing keywords because they sound right instead of because the data gives them a path.

Start with one term in the free App Store keyword checker. If it looks weak, test a more specific phrase. If it looks promising, check the result page before you spend metadata space on it.
