Questions

What is an App Store SEO tool?
An App Store SEO tool, also called an appstore SEO tool or ASO tool, helps you pick the keywords your app should rank for. It shows how often people search a keyword and how hard it is to rank for. The practice is called ASO, App Store optimization.
Is there a free App Store SEO tool online?
Yes. Storetide is a free appstore SEO tool that runs in your browser. You get five keyword searches a week with no account. Pro is 4.90 euros a month, or 3.90 euros a month on a yearly plan.
How does the tool know how many people search a keyword?
It doesn't know exact numbers, and nobody outside Apple does. Apple publishes a relative search popularity score from 1 to 100 through Apple Ads, and Storetide shows that score. Keywords Apple doesn't list are marked as not in its list.
Are these Apple's popularity scores?
Yes, popularity is the score Apple publishes through Apple Ads. Difficulty and potential are Storetide's own estimates. Storetide isn't affiliated with Apple.
How many searches are free?
Five keyword searches a week. Searching the same keyword and store again in one visit doesn't use another one. Pro has no limit.
How much is Pro?
4.90 euros a month, or 3.90 euros a month if you pay for a year up front (46.80 euros once a year). You can cancel any time.
What does the app optimizer do?
Paste your App Store link and Storetide reads your app's name, description and genre. It then picks the keywords that fit your app best in the store you choose, and fills in a title, a subtitle and a keyword field you can copy. It is part of Pro.
What is the potential score?
A score from 0 to 100 that averages the factors you switch on: popularity, suggestion rank, weak competition, stale apps, weak apps, title gap and momentum. You can turn each one on or off.
What is the Top potential list?
Popular keywords where the top 10 apps are still beatable, ranked by potential score.
How often are the lists updated?
Apple publishes its search popularity data monthly. Each list shows the latest full month for the store you pick, or the highest score across all stores for Worldwide, and the month is printed under the list. Trending compares it with the month before. We refresh the data every week and keep the history. The competition for the Top potential list is checked live when you open it.
Do you store my searches?
No. A search goes to Apple and the answer comes back. Keywords aren't saved.
