Whenever you open an ASO tool such as AppRadar, Mobile Action or ASORanker, the first number you look at is usually search volume. It is commonly shown on a scale from 1 to 100 and represents the popularity of a query on the App Store.
But volume alone can be misleading. A large number may actually be your worst option if you ignore the context. Here is how to read that signal for stronger mobile ASO decisions.
1. The score is relative, not absolute
Apple does not reveal exact monthly search counts. The "popularity" score you see is an estimate derived from Apple Search Ads data.
- 10-20: very low volume, often extremely niche terms.
- 30-50: the sweet spot for many apps, with useful traffic and manageable competition.
- 60+: high traffic, usually broad terms such as "travel", "banking" or "games".
2. Relevance matters more than raw volume
A keyword with a score of 80 is worthless if the user intent does not match your product.
The classic mistake: targeting "calendar" for a note-taking app only because the number looks attractive. The result: you might earn a few impressions, but almost no downloads. Apple notices the poor conversion signal and pushes your ranking down.
3. Why opportunity score matters
At ASORanker, we focus on the relationship between volume and difficulty.
If you go after a keyword with volume 50 but the top 10 results are dominated by apps with one million reviews and weekly updates, your opportunity score is almost zero.
The rule of thumb: look for imbalance. Anything above volume 30 with difficulty below 40 can be a strong niche opening.
4. Seasonality and trends
Search volume is not static.
- "Diet" spikes in January.
- "Christmas gift" surges in December.
- "Paris Olympics" had huge volume before collapsing again.
Pro tip: review historical trends before shaping your whole strategy around a short-lived spike that will disappear next month.
5. How do you find hidden keywords?
The best keywords are rarely the obvious ones. That is where long-tail strategy becomes useful.
Instead of chasing "Yoga" (Volume 70, Difficulty 90), go after "Yoga for back pain" (Volume 35, Difficulty 20). Traffic is lower, but ranking first on that niche query is where most downloads happen.
Conclusion
Search volume is a compass, not a destination. For effective mobile ASO, always prioritize relevance over raw volume and feasibility over popularity.
ASORanker helps you automatically calculate the right balance between search volume and difficulty so you stop wasting time on impossible keywords.
