The Search Terms report as a research source
Expert: with sources and numbers. Plain: the same, without them, for beginners.
The only real App Store query data a developer can get, and how to turn it into organic metadata.
Apple publishes no search volume data. This report is the closest thing that exists, and it is frequently the strongest business case for running Apple Ads at all.
What it contains
A “All search term and corresponding keyword performance in all search results ad groups and campaigns in a single campaign group”, showing search terms that led to impressions, taps and conversions, with terms addable as keywords or negative keywords directly from the report. (Reporting options and definitions, verified 2026-09-18)
A It reveals the queries Search Match matched your ad to automatically, the part you did not supply, and therefore the part that teaches you something. (Keywords best practices, verified 2026-09-18)
A Impression share is reported against the total number of searches on that search term (Reporting options and definitions), the nearest available proxy for a term’s total volume.
What it actually measures
Real queries, typed by real people, in a specific storefront, during a period in which you were bidding.
Not total market volume, volume you paid to observe. That limit is also the value: each term arrives with a tap rate and a conversion rate attached, which no third-party volume estimate provides (30-02).
The conversion rate is the part worth having. A term with volume that does not convert is a term you do not want in your metadata either. Discovering that for the price of a small test is cheap; discovering it after an iOS release is not, because the keyword field only ships with a build (10-09).
Harvesting into organic
A Apple documents the paid half of this loop: run Search Match in a dedicated discovery campaign, identify high performers, move them into focused campaigns (Keywords best practices).
B Taking those same proven terms into organic metadata at the next release is the extension, reported consistently by independent practitioners, and the obvious use of the data once you have it. Procedure in runbooks/apple-ads-discovery-and-keyword-harvest.
Read the Search Terms tab, not the keyword tab. Keywords are what you supplied. Search terms are what people typed. Teams that report on the keyword tab never see the discovery.
Look for phrasings, not just terms. The most useful output is often how people describe the thing, vocabulary you would not have generated, especially in languages you do not speak (30-05).
The limits
Budget bias. You observe terms you bid on or that Search Match reached. Low-bid terms in expensive categories stay invisible.
Small numbers. Eleven taps and one install is a 9% conversion rate with an enormous error bar. Do not act on early per-term rates.
Storefront-bound. Terms observed in one storefront say nothing about another.
Paid intent is not organic intent. A term converting well on an ad may behave differently in an organic result, with different placement and no ad label.
No Play equivalent. Play Console reports organic search terms (30-01); Google Ads app campaigns do not expose keyword-level search terms this way (95-02). This technique is iOS-specific.
Making the business case
If you need to justify Apple Ads spend beyond its media value: iOS provides no organic query data at all. A modest discovery campaign is the only way to buy it, and it is usually cheaper than a wasted release cycle spent on terms nobody searches.
Argue it as a research line, with the installs as a by-product.
What goes wrong
Reporting on keywords instead of search terms. Misses the discovery entirely.
Acting on ten taps.
Never harvesting. Data accumulates in the ad account and never reaches metadata. The most common failure, the loop is a habit, not a feature.
Generalising across storefronts.
Treating observed volume as market volume. You saw what you paid for.
In short
Every fact on this page in one line, with its evidence tier, source and verification date, 3 A · 1 B. Generated from the claim register, so it cannot drift from the page above.
The centre publishes no data at all on how often anything gets asked for. This read-out is the closest thing that exists, and it's frequently the single strongest business case for running a paid billboard at all.
What it actually contains
Every question and its matching word's performance, across every order in a group, showing exactly which questions led to being seen, being tapped, and an actual walk-in, with any of those questions addable straight from the report as a word you bid on, or one you deliberately exclude.
It reveals the exact questions the centre's own automatic matching decided to show your billboard for, the part you never actually supplied yourself, and therefore the part that genuinely teaches you something new.
Your share of a word's appearances is reported against the total number of times that exact question was ever asked, the closest available stand-in for that word's true total volume.
What it actually measures
Real questions, typed by real people, in one specific branch, during a stretch when you were actually bidding.
Not the whole market's worth of asking, the slice you paid to actually observe. That limit is also exactly where its value comes from: every word arrives with its own tap rate and conversion rate attached, which no outside guesser's volume estimate can ever give you.
The conversion rate is the part genuinely worth having. A word with real volume that never actually converts is a word you don't want in your permanent writing either. Discovering that for the price of a small test is cheap. Discovering it only after a full rebuild has shipped is not, because your hidden pocket only ever ships bundled with one.
Harvesting this into your permanent, unpaid writing
The centre documents the paid half of this loop itself: run its automatic matching inside a dedicated discovery order, find whatever performs well, move it into your more focused orders.
Taking those exact same proven words into your own permanent writing at the next refit is the natural extension, reported consistently by experienced shopkeepers, and the obvious thing to do once you actually have the data in front of you.
Read the actual-questions tab, not the words-you-supplied tab. The words you supplied are what you already knew. The actual questions are what people genuinely typed. Anyone reporting only from the words-you-supplied tab never sees the real discovery at all.
Look for whole phrasings, not just individual words. The most useful thing this ever gives you is often how people describe the thing they want, vocabulary you'd never have come up with yourself, especially in a language you don't personally speak.
The real limits
A bias toward whatever you paid for. You only ever see words you bid on, or ones the automatic matching happened to reach. A cheap word buried inside an expensive category stays completely invisible to you.
Small numbers lie. A handful of taps and one single walk-in looks like a striking conversion rate, with an enormous margin of error hidden behind it. Don't act on an early, tiny per-word rate.
Bound to one branch. Words observed in one country say nothing at all about a different one.
Paid intent isn't unpaid intent. A word converting well as a paid billboard may behave completely differently in an unpaid result, with different placement and no advertising label attached.
No real equivalent on the other centre. That side reports its own unpaid search questions, but its own paid advertising system doesn't expose word-level results the same way at all. This whole technique is largely specific to this one centre.
Making the actual business case for this
If you need to justify spending on a paid billboard beyond its advertising value alone: this centre otherwise gives you no real query data at all. A modest discovery order is the only way to actually buy it, and it's usually far cheaper than an entire wasted refit cycle spent on words nobody actually asks for.
Argue for it as a genuine research line, with the walk-ins themselves as a welcome side effect.
What tends to go wrong
Reporting from the words-you-supplied tab instead of the actual-questions tab. Misses the whole discovery entirely.
Acting on a tiny handful of taps.
Never actually harvesting the results. The data just piles up inside the billboard account and never reaches your permanent writing. The single most common failure, the loop is a habit you have to build, not something that happens automatically.
Generalising a result across different branches.
Treating observed volume as the whole market's real volume. You only saw what you paid to see.
