The five ASO metrics that actually drive decisions are: keyword rankings (check weekly), impressions (weekly in App Store Connect), product page views and tap-through rate (weekly, healthy range is 6-10%), conversion rate (biweekly, average is 25-35%), and downloads from search (weekly). Track these in a 15-minute Monday morning routine and write a one-sentence weekly summary to build a decision log.
You've done your keyword research, optimized your subtitle, and pushed an update. Now what? If you're not tracking what happens next, you're optimizing blind. You won't know which changes helped, which ones hurt, or what to try next.
But ASO tracking has a trap: too many metrics. Between App Store Connect, third-party tools, and your own analytics, you can drown in numbers without any of them leading to your next decision.
Here are the five metrics that actually matter, how often to check them, and what to do when they change.
1. Keyword rankings
Your rank position for each keyword you're targeting. This is the most direct measure of whether your ASO changes are working, and it moves before anything else does.
What to look for:
- Movement after an update. Did your target keywords improve, stay flat, or drop? Give it at least two weeks after a metadata change before judging.
- Surprise rankings. Sometimes Apple ranks you for terms you didn't explicitly target. These are free insights into how Apple's algorithm interprets your metadata.
- Sudden drops. Usually means a competitor updated their metadata or a new app entered the top results for that keyword.
How to read the changes:
- Moved from unranked to top 50: your metadata is getting indexed. Wait another week.
- Moved from 30-50 to 10-20: real progress. This keyword is worth keeping.
- Stuck at 15-20 for 4+ weeks: you've likely hit your ceiling with current metadata. Either strengthen it (move the keyword to your subtitle or app name) or focus elsewhere.
- Dropped 10+ positions suddenly: something changed. Investigate.
How often: Weekly. Daily fluctuations are noise.
Where to get it: Apple doesn't show rank positions directly. You need a third-party tool. App Sprint tracks keyword rankings automatically so you can see position changes over time without manual searching.
2. Impressions
How many times your app appeared in search results or browse sections. Impressions tell you whether people are seeing your app at all.
What to look for:
- Impression jumps after keyword changes. A rise means your new keywords are putting your app in front of more people.
- High impressions, flat downloads. Your keywords are working but your product page isn't converting. The problem is your screenshots, icon, or subtitle, not your keywords.
- Sudden drops. Could mean a keyword lost relevance, a competitor overtook you, or Apple changed something in their algorithm.
How often: Weekly in App Store Connect.
Where to get it: App Store Connect, Analytics, Metrics, Impressions.
3. Product page views (tap-through rate)
The number of people who tapped on your app to see the full listing. This is different from impressions. Impressions mean they saw you in results. Product page views mean they were curious enough to tap.
The ratio between these two is your tap-through rate (TTR):
TTR = Product Page Views / Impressions
Benchmarks:
- 6-10%: healthy.
- Below 4%: your search result appearance (icon, name, subtitle, first screenshot) isn't compelling enough.
- Above 12%: strong match between keyword intent and your listing.
What drives TTR:
- Your app icon (is it clean and recognizable at small size?).
- Your app name (does it clearly describe what you do?).
- Your subtitle (keyword-rich or wasted on a tagline?).
- Your first screenshot (visible in search results, does it hook?).
If TTR is low, the fix isn't better keywords. It's a better search result appearance. Changing your subtitle alone can move TTR by several percentage points.
How often: Weekly.
Where to get it: App Store Connect, Product Page Views divided by Impressions.
4. Conversion rate
The percentage of product page visitors who download. This is the ultimate measure of how well your listing sells.
CR = Downloads / Product Page Views
Benchmarks:
- 25-35%: average for most categories.
- Below 20%: your product page needs significant work.
- Above 40%: you're converting well. Focus on getting more traffic.
What drives conversion:
- Screenshots (the biggest factor, by far).
- Ratings and reviews (below 4.0 hurts conversion significantly).
- Description (less impact than screenshots, but still matters).
- Price/monetization model (free with IAP vs. paid upfront).
Common patterns:
- High TTR + low CR: people are curious but your full product page doesn't close the deal. Focus on screenshots and ratings.
- Low TTR + high CR: your page is great but not enough people see it. Focus on keywords and your search result appearance.
How often: Biweekly. Conversion rates need volume to be stable. Wait for at least 200+ page views before drawing conclusions.
Where to get it: App Store Connect, or calculate manually from Downloads and Product Page Views.
5. Downloads from search
Total downloads attributed to App Store search. This is the bottom line. Everything else feeds into this number.
What to look for:
- Week-over-week trends. Are organic downloads growing, flat, or declining?
- The relationship to other metrics. If impressions are up but downloads aren't, conversion is the bottleneck. If conversion is strong but downloads are low, you need more impressions (better keywords, higher rankings).
- Source split. If search is less than 50% of your total downloads, there's room to grow organically. Check the breakdown in App Store Connect.
How often: Weekly.
Where to get it: App Store Connect, Downloads filtered by Search source type.
The 15-minute Monday morning routine
The biggest tracking mistake is checking everything daily. That leads to overreacting to noise and changing things too often. Here's a weekly routine that works:
Every Monday morning:
- Open App Store Connect. Check impressions, product page views, and downloads for the past 7 days. Compare to the previous 7 days.
- Check keyword rankings in your tracking tool. Look at position changes for your top 15-20 keywords.
- Calculate your TTR and CR for the week.
- Write one sentence summarizing the week: "Impressions up 15%, conversion flat. 'budget planner' moved from #18 to #12."
That's it. Fifteen minutes, once a week. No daily obsessing. The one-sentence summary is the most valuable part because it forces you to identify what actually matters and builds a log you can reference when making decisions.
What to do when the numbers change
Tracking only matters if it leads to action. Here's how to read the most common patterns:
Impressions up, downloads flat
Keywords are working. People are finding you. But they're not downloading. The problem is on your product page. Fix your screenshots first. Then check your ratings.
Impressions down, everything else flat
Your keywords lost effectiveness. Check which specific keywords dropped. Did a competitor update? Is the keyword trending down? Swap underperforming keywords with fresh alternatives from your research backlog.
High TTR, low conversion
People are curious enough to tap but the full page doesn't convince them. Your search result appearance is strong, your product page is weak. Focus on screenshot optimization and getting your rating above 4.0.
Good conversion, low impressions
Your listing sells well but not enough people see it. This is a keyword and ranking problem. Review your keyword field. Are you using all 100 characters? Are you making any of the common ASO mistakes that limit discoverability?
Everything flat for 4+ weeks
Nothing is moving in any direction. You either haven't made changes recently, or your changes were too small to register. Make a meaningful update: rework your keyword field, refresh your screenshots, change your subtitle. Give Apple's algorithm something substantial to re-evaluate.
When to change vs. when to wait
This is the hardest part. Here are the rules:
Wait when:
- You just pushed an update. Apple takes 3-7 days to reindex. Don't judge before two weeks.
- Fluctuations are small (plus or minus 3 rank positions, plus or minus 10% impressions). That's normal noise.
- It's a holiday or seasonal period. Traffic patterns shift. Don't mistake seasonal changes for ASO problems.
Act when:
- A keyword has generated zero impressions after 3-4 weeks. It's dead. Replace it.
- Conversion rate dropped 5+ percentage points after a change. Revert or iterate quickly.
- A competitor took your top keyword and you dropped to page 2+. Decide whether to fight (strengthen metadata) or pivot to other keywords.
- You have 4+ weeks of stable data and want to test a new approach.
The golden rule: Change one thing at a time. If you update keywords, screenshots, and subtitle in the same release, you won't know which change drove the results. Update keywords in one version. Screenshots in the next. Measure each independently.
Start tracking this week
If you're not tracking anything today:
- Open App Store Connect this Monday. Write down impressions, page views, and downloads.
- Pick your top 10 keywords and check your rank position (manually or with a tracking tool).
- Calculate your TTR and CR.
- Write it down. Compare next week.
After four weeks, you'll have enough data to see real trends. That's when ASO gets interesting, because you're making decisions based on evidence instead of guessing.
The developers who grow organic downloads consistently aren't the ones making the biggest changes. They're the ones tracking, learning, and iterating. Small improvements compound. Start with these five metrics and build from there.
