Hello I need help with the Bazaar ROI case study please. The case study is in Course Hero already its a Search Engine Marketing homework.

A key component of search engine marketing success lies within measurement, analysis, and optimization.

Bob and Myra focus on marketing analytics at Bazaar.com, leveraging search and display advertising efforts for Google and Bing. Their team is currently analyzing recent paid search efforts to understand the return on investment (ROI) of their branded keywords.

This case study provides an in-depth view of common questions that businesses encounter when assessing the strength, success, and legitimacy of their pay-per-click (PPC) campaigns.

To earn credit for this assignment, read the case study and answer the following questions:

1. Is Bob's ROI calculation of 320% for sponsored search ads for branded keywords potentially incorrect? What are your reasons for your answer? Support this with calculations or data-based references.
2. How could you improve the ROI calculation for sponsored search? Based on the data, conduct the calculation and show your work.
