How to tell if your ASO is actually working

ASO 26 July 2026 · 8 min read

Changing keywords feels productive. Redesigning screenshots feels productive. But without a measurement loop, ASO is astrology with better fonts. Here are the five numbers that actually answer "did that change work?" — and how to read them without an analytics SDK.

The funnel, in five numbers

Impressions — how often your app appeared in search results or charts. Keyword changes move this first.
Product page views — how many impressions became a visit. Your icon, title and first two screenshots move this.
Conversion rate — downloads ÷ impressions. The single best summary of listing quality, and the number screenshot redesigns exist to move.
Downloads — the result. Split first-time downloads from redownloads when you can; updates and redownloads flatter the total.
Ratings velocity — new ratings per week. It lags downloads by days but is public for every app, which makes it the one number you can also read for competitors.

Where the data lives

All of it comes from App Store Connect: App Analytics has impressions, page views and conversion; Sales & Trends has downloads and proceeds. Two habits make the data usable:

Log the date of every change. A keyword edit, a screenshot swap, a price change — without a change log, no chart can tell you anything.
Change one thing per release when you can. New screenshots and new keywords in the same week means neither gets credit.

Give each experiment two to three weeks. Search positions take days to settle after a metadata update, and weekly seasonality (weekends look different from Tuesdays) will fool you on anything shorter.

Ratings velocity: the competitor benchmark

Apple publishes each app's rating count publicly, per storefront. Snapshot it weekly — for your app and the apps ranking for your keywords — and you get a growth proxy no private dashboard gives you: if a competitor gains 2,000 ratings a month and you gain 40, that keyword's traffic is real and they're taking it.

Off-store traffic: campaign links

Running Reddit posts, a newsletter, or ads? Append Apple's campaign parameters (pt= your provider token, ct= a campaign name) to your App Store link and App Analytics attributes those downloads per campaign — no SDK, no pixel. One caveat: Apple hides campaign rows until they pass a small download threshold, so give small campaigns a few days.

Doing this without living in dashboards

This loop is exactly what Storeboard's Performance view (Pro) automates on your Mac: downloads, revenue, impressions, conversion and ratings charted per project, with competitor rating velocity tracked automatically alongside your keyword research. Ratings tracking works with no setup at all; sales and conversion read your App Store Connect data via an API key that never leaves your Mac's Keychain. The measurement stays honest because the data never passes through anyone's server — including ours.

The uncomfortable truth

Sometimes the answer is "it didn't work." A screenshot set you love can convert worse than the one it replaced. That's not failure — that's the loop functioning. Revert, keep the log entry, and you've paid one release cycle for a fact about your users most competitors don't have.
