What this question tests
Tests metrics design for a two-sided local advertising product: can you balance advertiser (local business) value against user (searcher) experience.
How to approach it
- Clarify the product: ads shown on local intent (nearby businesses or services), serving both the searching user and the local advertiser.
- Define advertiser-side metrics: click-through rate, conversion to a local action (call, directions, store visit), and advertiser renewal rate.
- Define user-side metrics: ad relevance, measured via click-through rate and a low ad-dismissal or complaint rate.
- Define a business-outcome metric: local ad revenue, guarded against maximizing revenue at the cost of relevance, since low-quality local ads erode trust fast.
- Add a guardrail: complaint rate stays low, since local ads tied to physical businesses carry real-world trust implications if misleading.
- Tie it together with a primary metric: verified local actions per impression, since that captures real value to both sides, not just clicks.
What a strong answer includes
- Picks verified local actions per impression as the primary metric, capturing genuine value over a vanity click metric.
- Separates advertiser value from user experience explicitly, since local ads need both sides to trust the system long-term.
- Adds a complaint-rate guardrail, recognizing local ads carry real-world consequences beyond a typical digital ad.
- Names advertiser retention as a health metric, since local businesses churn fast if ROI is unclear.
Common mistakes
- Treating local ads like generic display ads, missing the local-intent and physical-action dimension that makes them distinct.
- Optimizing purely for click-through rate or revenue without a guardrail for user trust or ad quality.
- No advertiser-side retention metric, missing that local businesses are often small and price-sensitive, unlike large ad buyers.
Likely follow-up questions
- How would you measure a call or store visit that resulted from an ad, given attribution is hard for local actions?
- How would you handle a local business that gets many clicks but few conversions?
- How would this differ for a national brand running a local ad campaign versus a small local shop?
