TTR (Tap-Through Rate)
The ratio of taps to impressions for an Apple Search Ads ad placement. Expressed as a percentage. TTR is the funnel-top efficiency metric — it tells you whether your ad is interesting enough to be tapped.
Also known as: Tap-through rate, TTR ASA
What is TTR?
Tap-Through Rate (TTR) is the percentage of Apple Search Ads impressions that resulted in a tap. It is Apple’s equivalent of Click-Through Rate (CTR) — the same metric, different verb.
The formula:
TTR = Taps / Impressions × 100%
If your ad showed 10,000 times and got 500 taps, TTR = 5%.
Typical TTR by campaign type
| Campaign type | Typical TTR | Notes |
|---|---|---|
| Brand (your own app name) | 20-30% | Brand intent is high; users were already searching for you |
| Brand defense (competitor’s name) | 8-15% | Lower than own-brand; many users still tap competitor |
| Category (high-intent non-brand) | 5-12% | Steady core driver of TTR volume |
| Discovery (Search Match + Broad) | 2-6% | Wider net, lower precision |
| Today Tab | 1-3% | Premium placement but pre-intent surface |
| Search Tab | 1-4% | Browsing surface, not active search |
Why TTR matters
TTR is the top of the paid-conversion funnel. Two campaigns with identical CR and CPT can have vastly different CPI just because of TTR difference:
| Campaign | TTR | CR | CPT | CPI | Daily volume @ 100K impressions |
|---|---|---|---|---|---|
| A | 8% | 35% | $2 | $5.71 | 2,800 installs |
| B | 3% | 35% | $2 | $5.71 | 1,050 installs |
CPI is the same but Campaign B requires 2.7× more impressions for the same install volume. In a capped-budget scenario, Campaign A wins.
How to improve TTR
- App icon clarity. The icon is the most prominent visual in the search results card. Test high-contrast and benefit-clear icons quarterly.
- First screenshot strength. For Search Results placements that show one screenshot, the first screenshot must communicate the core value in <2 seconds.
- App name match. ASA shows the app name on the card. Names that include the searched keyword (or a close variant) typically get 15-30% higher TTR.
- Star rating. Below 4.0 stars suppresses TTR meaningfully. Above 4.5 is the competitive zone.
- Tighter keyword targeting. Search Match casting too wide produces impressions on low-relevance queries — TTR drops because users don’t recognize the relevance.
Common TTR failure modes
- Icon refresh without testing. Replacing a familiar icon overnight drops TTR 20-40% for the first 2-4 weeks.
- Search Match drift. Apple expanded your match scope to new queries that aren’t relevant. Audit the Search Term Report for new low-TTR terms.
- Competitor entered auction. Their creative is stronger; you’re showing but losing attention. Either improve creative or accept the lower share.
- App Store featured spot ended. Featured spots inflate organic TTR; when they end, paid TTR can look worse relative to baseline.
