Final answer:
Inventory Turnover is not a website performance measure; it's a metric related to the speed of selling and replacing stock, whereas Page Load Time, Conversion Rate, and Bounce Rate are key website performance measures for online retailers.
Step-by-step explanation:
The correct answer is c) Inventory Turnover. The key website performance measures commonly used by online retailers include a) Page Load Time, b) Conversion Rate, and d) Bounce Rate. Inventory Turnover is not a website performance measure; instead, it's a measure of how quickly a company sells through its inventory within a given time period.
Each of these metrics provides valuable insight into the user's experience and the effectiveness of the website:
- Page Load Time is crucial because slow load times can result in higher bounce rates and lower user satisfaction.
- The Conversion Rate indicates the percentage of visitors who take a desired action on the site, like making a purchase.
- The Bounce Rate measures the percentage of visitors who navigate away from the site after viewing only one page, hinting at issues with user engagement or relevance of content.
Knowing that Inventory Turnover refers to the speed at which a company sells and replaces its stock, it is easy to see that it's not directly related to online customer behavior or website effectiveness.
