Business Plan

A new solution for Staples Online Sales

Link

In this project, we explore and analyze the situation of Staples in 2014, when the company was too

confident in traditional in-store sales methods and was slow in the race for e-commerce and digital

transformation. At the end of the project, we

propose a plan for both marketing and sales to

boost online sales for Staples.

Data Visualization (Power BI)

Marketing Performance Analysis

Link

This project assesses the performance of

marketing campaigns across multiple channels and

audience segments in 2022. Despite impressive

reach - $1.9B in spend, 4.4B clicks, and 13.5B

impressions - the results highlight channel

inefficiencies. Typically, Pinterest showed markedly lower ROI compared to other platforms. These

insights provide critical guidance for reallocating budgets and refining channel strategies to

maximize the impact of future campaigns.
