What the numbers mean
Auto parts leads Shopping CTR (1.20%) with cheapest CPC ($0.56) because searches are highly specific. When someone searches for a part number or exact component, they know what they need. This specificity drives both high CTR (exact matches) and reasonable conversion (ready buyers). Fitment data accuracy is critical—wrong fitment information creates returns and negative reviews. The $54.76 CPA reflects higher AOV than most Shopping categories.

How to act on this
Ensure fitment data accuracy in feeds—wrong parts create returns and destroy margins. Include part numbers in titles for exact-match searches. Segment by vehicle make/model for relevant bidding. Use merchant promotions for competitive differentiation.
