Savvy Internet retailer could make sure its ad runs in the late afternoon, when online shopping spikes but ad competition falls
From WSJ: Most online shopping happens on weekdays between 10 a.m. and 1 p.m. and then in the late afternoon between 3 p.m. and 5 p.m., largely at work, according to comScore Networks, a Chicago Internet market-research firm.
The highest percentage of dollars spent online during a typical weekday occurs between 11 a.m. and noon, followed by 4 p.m. to 5 p.m. and then 3 p.m. to 4 p.m., comScore says. By far, consumers spend the fewest dollars online in the hours between midnight and 8 a.m.
Peter Fader, a marketing professor at University of Pennsylvania's Wharton School, says some advertisers start running ads at midnight and exhaust their daily preset ad budgets by midday.
