The bottom line
Mobile Action gives more accurate keyword data than Sensor Tower for optimizing on Google Play. Its chance score shows which keywords are winnable, where Sensor Tower's difficulty score marks almost every keyword as too hard.
Key takeaways
- Good ASO means finding keywords with decent traffic and low competition. 2:59
- Low competition is marked as a Sensor Tower difficulty under 3, or a Mobile Action chance score over 70.
- One example keyword has a search score of 23 and very low competition.
- Sensor Tower rates almost every Google Play keyword as hard. 2:44
- Scores are never under 3 and usually sit around 5, 6 or 9 on a scale of 10.
- That leaves no clear keyword to target.
- Apps are already ranking for keywords that Sensor Tower calls too competitive. 3:52
- The first client ranks for these keywords before any optimization was done.
- Relying on Sensor Tower alone could mean skipping keywords that are in reach.
- Mobile Action's chance score matches real rankings better. 6:15
- One keyword has a Mobile Action chance of 98 and a Sensor Tower difficulty of 6.4, and the unoptimized app already ranks number 7 for it.
- Chance runs on a scale of 100, while difficulty runs on a scale of 10, so a 98 means a very high chance of ranking.
- Mobile Action is the tool to pick for Google Play, and a UK comparison is coming. 7:06
- Traffic scores are harder to judge, because one keyword shows 41 on Mobile Action and little traffic on Sensor Tower.
- Search volume can be checked against Google AdWords.
If you had to choose when you're trying to optimize for Google Play which ASO tool, I would recommend Mobile Action.

Chapter summaries
0:00 Why Google Play needs its own tool test
Google Play is an important channel, and the right ASO tool depends on real rankings, not on a tool's own scores.
- Real client rankings are the test for which tool is most accurate. 1:11
- The data comes from a couple of client apps, with keywords and app names hidden.
- The goal is to help anyone doing ASO alone choose a tool for Google Play.
- Google Play is less fun than Apple because it lacks the localization hacks and the many keyword fields.
- The agency is doing more Google Play optimizations and plans to share more stats.
1:44 Two client apps, before any optimization
Both tools were checked against where unoptimized apps already rank, and Sensor Tower's difficulty scores look too harsh.
- The spreadsheet puts each tool's scores next to the client's actual rank. 1:44
- Sensor Tower gives traffic and difficulty. Mobile Action gives search score and chance.
- Other columns show keyword length, the apps that show up for the keyword, and the client's rank.
- A higher chance score means a better shot at the top ten for that keyword.
- Highlighted cells are the keywords Steve judged to be low competition.
- Using both tools is the usual advice, and Mobile Action looks stronger on Google Play. 2:29
- An earlier three-tool case study found Sensor Tower and Mobile Action the most accurate on iOS.
- Rankings for the first app were taken before any optimization, so no Google Play work had touched it.
- A follow-up video will show how the same keywords rank after optimization.
- The second app shows the same pattern. 4:47
- It had launched but was not yet optimized, and it already ranks for some keywords.
- The columns are rearranged, but the rules are the same: difficulty under 3 or chance over 70 counts as low.
- Steve is unsure whose traffic score is more accurate, because the two tools disagree on one keyword.
5:34 Checking the scores against real data
Traffic scores can be cross-checked outside the tools, while the chance score is the number that predicts rankings.
- Traffic scores are trustworthy when both tools land close together. 5:44
- One keyword scores 50 on Mobile Action and 5.9 on Sensor Tower, so it likely has decent traffic.
- Google can be searched to see which tool is closer.
- The 41 keyword stays unresolved: who knows we don't know yet.
- Search scores can be verified against Apple and Google, so they are less of a worry.
- The chance score is the number to watch, because real rankings back it up. 6:08
- The app has not been optimized for the 98-chance keyword, yet it ranks number 7.
- That keyword is now getting extra work to push the ranking higher.
- Sensor Tower rates nearly all these keywords as very competitive, with nines common.
- No outside source exists to verify difficulty or chance, so the real rankings are the test.
