Running multiple A/B tests to identify the most effective design solutions that drive conversions and maximize sales.

Tested three variations across two product recommender positions on the product page, analyzing session data, revenue, conversion rate, and RPS to determine the most effective combination for driving sales performance.
Result:
Product Recommender A: "Viewed Together" delivered the highest Revenue and Revenue Per Share
Product Recommender B: "Most Valuable of Category" delivered the highest Average Order Value and Revenue Per Share
Next Step:
Increase traffic allocation to "Viewed Together" for Product Recommender A and "Most Valuable of Category" for Product Recommender B

Tested three price range sequences for product recommendations in ascending order, evaluating conversion rates across variations to identify the optimal pricing display order that best influences purchasing decisions.
Result:
Variation C recorded the highest conversion rate among all tested sequences, with Variation B following as the second best-performing price range order
Next Step:
Reorder price range display from ascending to descending order
Variation C > Variation B > Variation A

Evaluated three placement positions for social proof elements on the product page, measuring conversion rate, revenue, and AOV to determine the most persuasive location that encourages customers to complete a purchase.
Result:
Variation B consistently outperformed Variations A and C across all key metrics, including Conversion Rate, Revenue, and Average Order Value
Next Step:
Allocate 100% of traffic to Variation B

Revised and tested two variations of social proof copy within the same placement, comparing conversion rates to identify which messaging most effectively builds trust and motivates purchase decisions among site visitors.
Result:
Variation B delivered a conversion rate uplift of up to 3% over Variation A, proving the revised messaging to be significantly more effective in driving purchase intent
Next Step:
Maintain a 50/50 traffic split and introduce a new variation to further refine social proof messaging
