Ever wonder how your Amazon PPC ad campaigns are performing when compared to other sellers? 

Knowing how your campaigns stack up against the average Amazon seller can help guide you when creating strategies designed to enhance the performance of your PPC ad campaigns. 

Are you curious about the overall trends for Amazon Sponsored Product ads over the past year?

Sellers who regularly monitor data/trends are able to make informed decisions about their PPC campaign optimizations, which can provide them with unique advantages over their competitors. 

Key metrics can give sellers vital insights into the health of their Amazon advertising presence.  When monitored properly, sellers can use these metrics to sustainably scale their businesses while keeping Ad Spend low.

Unfortunately, not every seller knows how to use data/trends to increase their profitability while lowering their advertising costs. With so many metrics to track, it can be difficult to know which ones to focus on and improve.

That’s why it’s important for a seller to be aware of the average of Amazon advertising stats for key metrics like ACoS, Cost-per-Click, ROAS, Conversion Rate, click through rate percentage and even a few of the lesser known but equally important metrics. 

This blog will present several interesting trends occurring in the Amazon advertising space in order to help you to see how it has evolved in recent years.  

The data used in this blog references approximately 1,400 accounts (2018-2021), and this data is exclusively related to Sponsored Products ads data for the US marketplace.

ACoS Data/Trend

ACoS is the relationship between a seller’s Ad Spend and how much that spend is generating to the seller in revenue. 

Sellers should keep in mind when looking at this metric, that they must understand what they are optimizing for, and what the purpose of the campaigns are. 

Pro Tip: In large accounts with dozens or hundreds of campaigns, it’s normal to have a wide range of ACoS percentages throughout your campaigns as many of them are built to serve different objectives.

Range: 2018-2021

Ad Spend per Order Data/Trend

Click through rate Data/Trend

A seller’s click through rate is the total number of clicks their ad gets divided by the total number of impressions. The higher a seller’s click through rate is the more relevant their ads are to online shoppers.
