Say an advertiser makes $0.10 every time someone clicks on their ad. Only 20% of people who visit the site click on their ad. How many people need to visit the site for the advertiser to make $20?
200
Check this.
0.1x = 20
x = 200 must click on the ad.
0.2y = 200
y = 1,000 must visit the site.
To find the number of people who need to visit the site for the advertiser to make $20, we first need to calculate how many people need to click on the ad in order to earn $20.
Since the advertiser earns $0.10 for each click, we can determine the number of clicks needed by dividing $20 by $0.10:
Number of clicks = $20 / $0.10 = 200 clicks
However, only 20% of visitors click on the ad. To calculate the total number of visitors needed, we need to divide the number of clicks by the click-through rate (CTR):
Total visitors = Number of clicks / CTR
In this case, the CTR is 20% which can be written as 0.20. Plugging in the values:
Total visitors = 200 clicks / 0.20 = 1000 visitors
Therefore, in order for the advertiser to make $20, they need 1000 people to visit the site.
