Most businesses by now are well versed with the consequences of the COVID-19 pandemic: Faltering offline sales, flexible work-from-anywhere options, fluctuating foot traffic with lockdown mandates and e-commerce becoming a channel many brands wished they had built infrastructure for earlier.

As a record number of consumers in Southeast Asia move from shopping malls to online platforms like Shopee, Lazada, Tiki and Tokopedia, the advertising dollars are naturally flowing in. Emerging markets are witnessing the advent of retail media right now.

Amazon paved the way in North America in 2018 by launching Amazon Advertising to become the first bid-and-buy marketplace. BCG now estimates retailers have a $100 billion business opportunity to capture, if they can keep up.

To understand why retailers will capture more ad spend, it’s important to evaluate what modern day marketing has become.

Is it bus stop advertisements? Bidding on Google keywords or a Clubhouse session? Or is it a viral TikTok video? As the world becomes more connected and the lines between offline and online blur even more, modern day marketing is a mix of all the channels tied to key performance metrics.

The main goal of marketing, no matter the medium, is to highlight a business or product to the right consumers to score a potential sale. And like most things, there is a bad, a good and a much better way of doing things.

E-commerce as an advertising channel is unique, because it encapsulates the entire consumer journey from start to finish, especially as marketplaces continue to steal the share of search from search engines.

Traditional marketing channels were primarily linear TV, radio and print, because the mediums were highly popular at the time. However, with the birth of the internet newer platforms emerged such as email, websites and streaming. Then came the rise of social media and apps that shook up the advertising landscape. But regardless of these shifts, there has always been one constant: The business went where the consumer was.

So when sources of traffic and revenue once again change, let’s say due to a pandemic, the marketing mix follows. In the next 12 months alone, many marketers are planning to decrease spending in cinema, print and out of home (OOH), while the majority will increase budgets in social and search, according to Nielsen.

So which channels will benefit as money flows out of outdated buckets? A good indicator is ad revenue trends in mature markets like the U.S. While Google and Facebook remain the dominant advertising players, Amazon has eaten into the duopoly’s ad revenue pie in the U.S., growing its share from 7.8% to 10.3% in 2020 alone, according to eMarketer.

How? Because the most valuable advertising channel is the one that has the most measurable touch points with the consumer.
