In the Olympics of digital advertising, Amazon has earned itself a bronze medal.
That’s because market research firm eMarketer says U.S. advertisers will spend $4.61 billion on Amazon’s platform this year, accounting for 4.1 percent of overall spend, which will make it the No. 3 digital advertising platform in the U.S.
That means it is leapfrogging Oath and Microsoft for the first time—and is now directly behind Facebook and Google.
EMarketer said much of Amazon’s growth is due to an accounting change that affected estimates for 2018 and beyond. Nevertheless, eMarketer said the forecast increases its estimate of Amazon ad revenue by 10 to 12 percent in 2018, thanks to organic growth that was stronger than expected.
In fact, eMarketer expects increases of more than 50 percent per year through at least 2020, when Amazon will claim 7 percent of U.S. digital ad spend.
That’s still a far cry from the duopoly—Google has a 37.1 percent share, and Facebook commands 20.6 percent this year—but eMarketer expects Amazon—and, to a lesser degree, Facebook—to grow their respective shares. And, by 2020, eMarketer says Google’s share will drop to 35.1 percent.
“Its strong handle on consumer purchase behavior sets it apart from Google and Facebook in the digital ad market, which has made the company an attractive option for advertisers,” said Monica Peart, eMarketer’s senior director of forecasting, in a statement.
EMarketer said the jump in market share is also attributable to consumers increasingly starting product searches on Amazon instead of Google.
“That increased search traffic gives third-party sellers a reason to increase bids for keywords on Amazon,” Peart added.
