ComScore estimates mobile accounts for more than 20% of online sales so far this holiday season.

Desktop online shoppers in the U.S. are on a record-setting spending streak.

New data from comScore Inc. shows that shopping on desktop devices eclipsed the $1 billion mark every day from Thanksgiving through Dec. 4, the first time that has happened. During Cyber Week alone, from Nov. 28-Dec. 4, shoppers spent $10.980 billion on desktop, up 12.7% from $9.745 billion for the same period last year.

“We’re seeing billion-dollar shopping days become the new norm, with 11 consecutive days eclipsing that milestone on desktop—a trend we expect to continue through the current week and beyond,” comScore CEO Gian Fulgoni says.

ComScore does not yet have exact figures for the amount spent on mobile devices during that time, however Andrew Lipsman, comScore’s vice president of marketing and insights, says mobile commerce for the holiday season thus far should be “somewhere north of 20% of total digital commerce.”

Factoring in mobile sales would bring total online spending to approximately at least $13 billion during the week of Nov. 28-Dec. 4.


While Black Friday posted the strongest year over year online sales growth rate (19.0%) of any of the individual dates measured, Cyber Monday (17.1%) remains the leader in terms of online desktop sales, with shoppers spending more on the Monday after Thanksgiving alone ($2.671 billion) than they did on the Saturday and Sunday before it combined ($2.486 billion), comScore says. Shoppers spent $1.970 billion on desktop on Black Friday, up 19.0% from $1.656 billion last year.

From Nov. 1-Dec. 4, shoppers spent $37.986 billion on desktop devices, up 12.1% from $33.872 billion during the same period last year.

Meanwhile, e-commerce platform provider Kibo Commerce reported overall online sales for its clients on Black Friday were up 14% year over year. Mobile proved to be lucrative, with 58% of all purchases from more than 500 Kibo clients being completed on mobile devices. Kibo was formed in 2015 when e-commerce platform provider MarketLive Inc. and order fulfillment software firm Shopatron merged.

Web performance vendor Yottaa, which works to speed and optimize the performance of desktop and mobile sites, reports that during the period from Black Friday through Cyber Monday, its clients saw a 45% year-over-year spike in mobile conversions and a 47% jump in overall online sales.


According to Adobe Digital Insights, from Nov. 1-Dec.  5, shoppers spent $52.16 billion online on desktop and mobile devices, up 7.8% year over year, with all but one day during that span—Saturday, Nov. 5—producing more than $1 billion in online sales in the U.S.
