If you’re a third-party Amazon seller advertising on the marketplace then it’s essential that you measure how it performs. Sellers want to gain buyers’ attention affordably — so, if you’re spending a lot of money on advertising and not seeing much back in terms of extra sales, then you might want to stop or optimise it.

In a study by Econsultancy, 77% of marketers agreed that the success of advertising should drive the level of budget allocated to it.

There are many ways to measure the success of Amazon advertising. This post will examine Amazon TACoS which has started to gain traction recently as a key performance metric.

Before we dive in any further, let’s start with the basic question.

What Does Amazon TACoS Mean?

Amazon TACoS has nothing to do with Mexican food. Instead, it stands for the total advertising cost of sales. It measures your advertising spend relative to the total revenue generated.

The TACoS metric is growing in popularity across the ecommerce sector and gives you a snapshot of how your Amazon PPC ads are performing and directly affecting sales.

How to Calculate Your TACoS

To work out your TACoS, you divide your total advertising spend by your total sales revenue and then multiply it by 100.

TACoS = (Advertising Spend/Total Revenue) x 100

With this information, you can better decide how much your advertising is driving sales.
