Definition
Ad rank is a system used in search auctions to decide ad position. It is influenced by bid and quality signals.
How to use it
- Higher bid does not guarantee top position if quality is weak.
- Improve landing page experience and relevance to raise rank efficiently.
Why this matters
This term matters because it affects how you interpret performance and make budget decisions. If you use inconsistent definitions or windows, ROAS/CPA can look "better" while profit gets worse.
Practical checklist
- Write a 1-line definition for "Ad Rank" that your team will use consistently.
- Keep the time window consistent (weekly/monthly/quarterly) when comparing trends.
- Segment results (channel/plan/cohort) before drawing big conclusions from blended averages.
- Sanity-check with a related calculator from the same category on MetricKit.
- Read the related guide (e.g., Max CPC and break-even CPC: how to set bidding targets from margin) for context and common pitfalls.
