What is an ASO score, not just a number
An ASO score is a 0 to 100 rating of your app's store listing optimization across keyword relevance, title strength, description quality, visual completeness and preview text effectiveness. The app store optimization score focuses on signals that Google Play and the App Store actually rank by: keyword positioning, character usage, screenshot quality and conversion funnel clarity. An app ASO rating measures how your metadata aligns with what the stores reward in search and browse.
App developers and ASO specialists use an ASO score to audit any app (their own or competitors') without a subscription tool. The report ranks the fixes by weight, so a weak title (25 of 100) is flagged ahead of a freshness issue (10 of 100). Score a few competitors alongside your own listing to see where the gap is; the tool reads any public store page.
What the ASO Score checks
The score covers the five parts of a listing that the store algorithms and the humans scrolling past both react to. Each is scored 0 to 100 and weighted into the total.
| Area | Weight | What is checked |
|---|
| Title and subtitle | 25 | Keyword use, length against the 30-character limits, clarity of what the app does |
| Description | 25 | Whether the first three lines carry the hook and the main keyword, structure, feature clarity, a call to action |
| Ratings and reviews | 20 | Average rating and rating volume against what the category usually shows |
| Visuals | 20 | Screenshot count against the 10 slots on Apple and 8 on Google Play, and whether the set looks complete |
| Freshness and localisation | 10 | How recently the app was updated and how many languages the listing supports |
The public store data is read first, then a language model writes the findings and fixes from that data only. If a field is not available, the report says so instead of guessing.
Apple does not publish the subtitle or the 100-character keyword field through its public lookup, so those two are never scored from real data. Google Play screenshot counts are read from the page and are approximate. Neither store exposes conversion rate, impressions or keyword rankings. For those you need App Store Connect, the Play Console, or a paid ASO tool. This score is the part of the audit you can run on a competitor as easily as on yourself.
The rules the score is built on
- Apple: app name up to 30 characters, subtitle up to 30, keyword field up to 100, promotional text up to 170, up to 10 screenshots per device size.
- Google Play: title up to 30 characters, short description up to 80, full description up to 4,000, up to 8 screenshots per device type.
- Words already in the title and subtitle are indexed once on Apple, so repeating them in the keyword field wastes characters.
- Google Play indexes the full description; Apple does not index the description at all.
How to read the score
- Under 45. The listing is costing you installs you already paid to attract. Fix the title and first three description lines this week, then screenshots.
- 45 to 70. Normal for an app that has not been through an ASO pass. Work the fixes in the order the report gives; the top three are usually the title, the first screenshot and rating volume.
- Over 70. The basics are in place. Gains now come from A/B testing screenshots, localising the top five markets and a ratings prompt at the right moment in the app.
Run the tool on the three apps that rank above you for your main keyword. The gap between their scores and yours is the shortest list of things to do.
How to use the score
- Enter App Store or Google Play URL: Any public listing works, including a competitor's.
- Choose What matters most right now.
- Press Score this listing. The report takes about 20 to 40 seconds to write.
- Enter your email when asked. The full report appears on the page and a copy is sent to you so you can share it.
- Read the report top to bottom: the score, the findings in priority order, then the fixes. Use Copy report to paste it into a doc or a message.
- Change an input and run it again to compare scenarios; the link in your address bar carries your inputs.
Questions people ask
Can I score a competitor's app?
Yes. Any public listing works. Scoring the three apps above you for your main keyword tells you what they do that you do not.
Why does it ask for my email?
Each report costs us to run and we send you a copy so you can share it with a developer or designer. We do not add you to a sequence.
Why can it not see my keyword field?
Apple keeps the keyword field private. It is visible only in App Store Connect. The report scores what the public page shows, which is also what your users see.
Is the score the same as my ranking?
No. Ranking depends on downloads, velocity, ratings and keyword competition as well as the listing. A strong listing converts more of the impressions you get; it does not create impressions on its own.
How often should I re-run it?
After every listing change, and once a month otherwise. Ratings and update recency move the score without any edit from you.
What happens after the report?
Nothing unless you want it to. The report ends with a link to talk to ApsteQ's app growth team. Most people take the fixes and do them in-house.
What is a good ASO score?
There is no published average; the score is this tool's rubric, weighted 25 for title and subtitle, 25 for description, 20 for ratings, 20 for visuals and 10 for freshness. Use it two ways: compare your listing against competitors you score with the same tool, and re-run it after each fix to confirm the number moved. Title, description first lines and screenshot count are the fixes that move it most.
Does my ASO score affect my app store ranking?
Indirectly. The ASO score measures keyword positioning, title strength and description clarity, which all affect search ranking. A higher app listing score correlates with higher organic visibility, but the score itself is not what the app store uses to rank. Installs and reviews still matter most.
