A/B Title Tests Boosts Impressions +13%

Small Changes Drive Performance Growth

Challenge: This fashion retailer wanted to test whether adding “Size Fit” to product titles would improve Google Shopping performance.

While size fit could help shoppers quickly assess suitability, it risked pushing other important keywords out of view on mobile, where space is limited - potentially affecting engagement and conversion rates.

Approach: We ran a 2-week A/B test (1,000 SKUs, split 50/50), comparing:

Control: Titles without “Size Fit”
Test: Titles with “Size Fit” included

Performance was measured on impressions, clicks, and potential uplift if the change was applied feed-wide.

Outcome: Including “Size Fit” increased impressions by 13.19% and clicks by 3.51%, with projected feed-wide gains of +100,904 monthly impressions and +584 monthly clicks.

This made including “Size Fit” the recommended title format for maximising visibility and traffic in this category.
