2017 sales grew across the three-day period from the Wednesday before Thanksgiving to Black Friday, showing 21 percent year-over-year revenue growth and 11 percent purchase growth. Average order value over the same period was up slightly, with YOY growth of nine percent. Additionally, purchases were up 17 percent during the two weeks leading up to Thanksgiving week, supporting predictions of an early peak shopping period in 2017. These figures give retailers early promise to what the company expects to be a positive 2017 holiday selling season, forecasted by Adobe to reach $107.4 billion overall. Rakuten Marketing supports these figures with Thanksgiving week highlights defining consumer shopping behaviors during the year's most critical shopping week of the year.

• Combined revenue growth across Thanksgiving and Black Friday was 23 percent YOY.

• Online revenue and purchases on Thanksgiving Day grew 28 percent and 35 percent YOY respectively.

• Online revenue on Black Friday grew 21 percent and AOV grew 24 percent, though purchases were down three percent, a further indication of consumers spreading spend across more days, but saving the bigger ticket items for Black Friday.

• Peak revenue and purchase activity occurred at 2:00 pm ET on Black Friday.

• Click-through and ad engagement rates surged in the week prior to the holiday, up 154 percent and 111 percent respectively, indicating the consumers were researching products for their holiday shopping gift list in advance of the peak shopping days.

• Consumers are more and more comfortable shopping on mobile devices, with smartphone shopping up over the course of the full Thanksgiving Week, Sunday-Friday. Mobile revenue grew by 43 percent, purchases by 34 percent, and AOV by seven percent.

Holiday retail sales results from Thanksgiving week show the continued power of peak promotions. Rakuten Marketing stresses the importance of cross-device measurement and attribution in order to capitalize on the overall holiday selling period. Insight into constant and rapidly evolving consumer shopping behaviors allows advertisers to anticipate, prepare and execute marketing strategies during peak sales hours on peak sales days.

"Holiday shopping behavior is evolving year after year, and we continue to experience outstanding growth as consumers open their wallets in response to retailer strategies during the peak holiday shopping days," said Rakuten Marketing CEO, Tony Zito. "We expect this upward growth to continue into Cyber Monday, and encourage brands to focus on strategies that re-engage the shoppers who have visited their site over the past week who may be holding out to see if there are deeper discounts on Cyber Monday."
