Offer development: how i created an attractive bundle

To increase sales, I created a bundle that combined complementary products at a discounted price. An analysis of customer purchases revealed that 60% of them bought a particular item together with an accessory. Based on that, I created three bundles: basic, intermediate, and premium, each offering a progressively larger discount. For example, the premium bundle offered 25% off compared to buying the items separately. I improved the visual presentation with high-quality images and descriptions that highlighted the savings and convenience.

Test results: before-and-after comparison

I ran A/B tests to compare the conversion rate before and after implementing the upsell. Before, the average conversion rate was 2.5%. After introducing the bundle, it rose to 3.3%. In addition, the average number of items per order increased from 1.8 to 2.4, generating a 30% increase in revenue in the following weeks.

Impact on the customer experience: feedback and metrics

Customer feedback was positive. I conducted a post-purchase survey, and 85% of respondents said they found the offers appealing. Metrics such as Net Promoter Score (NPS) increased from 45 to 65. This indicates that customers are more satisfied and more likely to recommend the store. Social media engagement also increased, with more comments and shares about the bundle.

Cart abandonment analysis: how i reduced it by 15%

The cart abandonment analysis showed that before implementation, the abandonment rate was 70%. After introducing the upsell, it dropped to 59%. One factor that contributed to this decrease was adding a reminder about the attractive bundle on the checkout page, encouraging customers not to miss the chance to save. I also set up cart recovery emails mentioning the bundle, resulting in a 40% open rate.

Direct marketing strategies: the decisive moves

To promote the new offers, I used segmented email marketing and paid ads on Facebook and Google. Segmentation allowed me to reach customers who had already shown interest in similar products. Facebook ads, optimized with FreeSpy data, focused on related interests and retargeting site visitors, increasing the click-through rate (CTR) by 20%. I also launched influencer campaigns to reach a broader audience, resulting in significant sales growth.
