How the Apple Ads auction actually works (hint: relevance gates, then bid + predicted performance)
ConsultMyApp analysed a real UK Apple Ads auction dataset and found semantic relevance isn’t the whole story. This summary captures the practical takeaway: treat exact/broad/search match as different eligibility gates, then manage Search Terms like a safety system.

Summary
ConsultMyApp’s analysis starts from a question most ASA managers have felt in their bones:
How much does semantic relevance actually matter once you’re “in the auction”?
They analysed a real UK dataset (keywords × the top auction positions), attached app metadata, then used a semantic scoring approach to compare:
- what an intuitively “most relevant” stack would look like, vs
- what Apple Ads actually showed in positions #1–#5.
The headline takeaway: Apple Ads is not a pure relevance auction.
Relevance seems to matter as an eligibility gate (especially for exact match), but bid + predicted performance do a lot of the final ordering work. That matches the lived reality: you can sometimes see bizarre Search Match outcomes at the top of a stack if you’re not policing search terms aggressively.
A useful mental model
Even though Apple doesn’t publish a formula, this is the practical model to plan around:
-
Candidate generation
- exact match
- broad match (expanded variants)
- Search Match (metadata + similarity + other signals)
-
Eligibility gating (relevance threshold)
- strictest for exact
- looser for broad
- loosest for Search Match
-
Auction ranking
- bid and predicted performance can reshuffle the winners after the gate
What to do with this (tiny win)
If you want one change that prevents the “why is this term spending?” surprise:
- Pick your top 3 Search Match campaigns.
- Pull the last 14 days of Search Terms.
- Add negative keywords for the bottom 10–20% by relevance (not just by CPA).
Treat this like brand safety, not optimisation. If you don’t, the auction will happily buy you visibility where users did not actually come for you.
