eCommerce Advertising in the US – A High-Level View


The eCommerce industry is experiencing a non-linear growth 

The eCommerce industry in the U.S. was approximately $600BN in 2019 and according to the U.S. Department of Commerce growing faster than 2018 at a pace of 13.6% is one of the fastest-growing areas of the economy.  


This big market is attracting large retail corporations as well as eCommerce entrepreneurs that are trying to capture a stronghold in the market. It is currently estimated that there are over one million eCommerce businesses in the U.S. alone (and growing daily), each competing for consumer attention using eCommerce advertising.

The influence of COVID 19

In relative terms, looking at the long-term eCommerce growth we observe that eCommerce sales in the US grew from 9% in 2016 to about 11% in 2019 and was predicted to cross 12% this year 2020. 


However, COVID19 changed the course and probably made the industry jump 4 or 5 years into the future displaying a non-linear step-function growth with initial evidence in the US indicating an increase of over 50% in many online sales categories. 


With the changing consumer purchasing behavior and the shrinking brick-and-mortar stores, the post-crisis eCommerce share of all retail will most probably be much higher than forecasted.

Seizing the opportunity 

The booming eCommerce attracts many businesses that would like to join and seize the opportunity. But the more retailers, the more critical becomes the need to stand out from the competition in the fight for the attention of the consumer.


In the world of physical retail stores, the task of getting discovered is translated into real-estate and location. Be it the High-Street or the Shopping Mall, retail businesses must be discovered and make it easy for their customers to know of their available merchandise. 


In the digital space, however, getting discovered and grabbing the volatile consumer attention, largely means turning to The Big Three websites.

In similarity to the physical world, there are two alternatives for online stores.


Online store on a Marketplace

The Shopping Mall can be compared to the online Marketplace, with Amazon being the largest and far behind are eBay and Etsy servicing retailers. The marketplace invests in creating a digital presence so that retailers on the platform can enjoy organic traffic from consumers. However, the marketplaces often get saturated with many retailers selling similar or same products, hence, retailers need to also use Pay Per Click (PPC) advertising plans offered by the marketplace.


The cost of Sales on a Marketplace

For professional sellers on Amazon amounts to a significant portion of their top-line revenue when they pay fees ranging from 6% to 25% (an average of 13%) of sales. This number contains the Amazon charges including selling plan fees and eCommerce advertising fees if so chosen by the seller.



Online store as an Independent Website

The alternative to the Marketplace is the independent online shop. Most of the eCommerce in North America and the UK is using one of the following technologies; Shopify, Magento, WooCommerce, and BigCommerce. There are differences in the technologies in terms of ease of use, time, cost, and skills required for setting up a web-store with these technologies.


Regardless of the chosen technology, an independently owned web-shop requires its owner to operate and advertise to get noticed, however in this case the effort and spend goes to the other two giants; Facebook and Google.

The cost of Sales for Online Stores

Research shows that successful online retailers spend as much as 22% of their top-line revenues on eCommerce advertising in an effort to bring relevant shoppers to their stores.

Why is the Cost of Sales going up

In contrast to brick-and-mortar, when selling online shops must ensure they are present on the first page whenever people are looking for their products. Even strong brands must keep this online presence at all times, therefore they execute several different activities such as creating Social Presence on Facebook and Instagram and improving their SEO (search engine optimization) to enable Google Indexing of the website that can help drive organic traffic of interested shoppers to the store products. 


But the biggest problem for the growing eCommerce is the supply of space on the first page vs. the demand of retailers. The ability to organically direct a substantial amount of shoppers traffic to the shops is limited. For that reason, the competition between retailers on the first-page moves to the paid advertisement, still, the limited supply of advertising space and the growing demand, constantly elevates the price of getting discovered. This means the cost of acquiring a new eCommerce customer is constantly increasing.


What can the retail advertiser do?

To stay profitable while growing sales, the digital retailer needs to crack the secret of How to Lower the Advertisement Cost (Lower PPC) and Elevate Exposure (Increase Impressions) to sell more at a lower cost. To do that, one must understand the logic of the AI robots responsible for placing Ads at the chosen Advertising Platform to ensure the Google Adwords campaign will receive a high relevance score.



Amazon, Google, and Facebook are doing everything to ensure their customers receive the best service. The meaning of “Best Service” however, is slightly different for the different platforms.

the Big 3

Amazon is focused on ensuring an overall positive shopping experience, therefore showing consumers with the highest scoring sellers (“Best Seller” badge) on the first page. Amazon retailers must ensure their customer ratings and reviews are high.


Facebook, on the other hand, is after ensuring their users see, at all times, the most relevant content to their interests including for that purpose relevant Advertisements. For that reason, and based on many analytics measurements, Facebook will give a high-quality score to relevant Retail Ads that convert well.


Google is after providing users with the most relevant search results. Simply put, for a retailer advertisement, if in response to a query, the user clicked on a search result on the first page and eventually made a purchase, it indicates a high-relevance of the Search Keywords to the Ad Text and the landing page on the target store-website. 


Ads with optimized Keyword-Ad-Landing page experience get a high-quality score. The high-Quality score will in turn make Google AI Robots prefer that Ad on others – this will Increase Impressions, and also lower the required PPC bidding cost, as the engine always looks to optimize the user experience, even at the cost of making less revenue to Google.


The conclusion here is that to drive sales up at lower PPC cost, the retailer must optimize its Ads relevance while increasing Ads exposure to ensure increasing amounts of interested shoppers arrive and buy the store products.
