How much Cebu Pacific would have to spend on advertising to get an additional 187,200 visitors a month to their website?
Inquirer.net charges $5 for every 1,000 times they show your ad on their site ($5 per 1,000 impressions or CPM).
Assume that for every thousand impressions, 40 people actually click on the ad (4% clickthrough rate) and end up visiting the Cebu Pacific website. So in order to get 187,200 visitors, the ad needs to be displayed 4,680,000 times (4,680 CPM).
At a cost of $5 per CPM, the advertising value of all that lost traffic is: $5 X 4,680 CPM =
$23,400 a month or $280,800 a year
