Question $4$: What do you think the ROI for the campaign is given your analysis?

First, calculate the return from running the campaign.

Calculate the average weekly incremental traffic attributable to sponsored ads $($the number multiply that by the average total weekly traffic from Google for Weeks $1-9.$

$156,585**0\mathrm{.}0162=2,544\mathrm{.}11$

Take that number and multiply by the average revenue per click

$2544\mathrm{.}11**2\mathrm{.}52=6,411\mathrm{.}17$

Now, calculate the cost of the campaign

What is the average number of sponsored clicks from Google during Weeks $1-9.$

$31,390$

Take this number and multiply by the cost of each click.

$\mathrm{.}60**31,390=18,834$

Calculate ROI

return from the campaign $-$ cost of the campaign$)/$cost of the campaign

$\frac{6,411\mathrm{.}165319-18,834}{18},834=-0\mathrm{.}6596=-65\mathrm{.}96$

Do you believe this campaign was successful? Why or why not? Bob's $320\%$ ROI was wrong. I do not th this campaign was successful because the ROI was negative, meaning thrat there has been a loss on the investment and the campaign was not as successful as it was previously thought to be$.$
