eCommerce Checkout or Check Out?

This is the question I’ve struggled with. Should I use checkout or check out?

For an online retailer getting users to complete the order is the most critical step. That we can all agree on.

What’s harder to agree on is the phrasing: is it checkout (one word) or check out (two words)?

From a grammar perspective Writing Explained has a solid explanation:

Check out is a verb phrase that means to sign for something or to observe something. Checkout means a place to buy things or the process of leaving a hotel as a noun, and it describes qualities of these things as an adjective.

Writing Explained

Based on the definition above I’m leaning towards declaring checkout is the way eCommerce retailers need to use it on their sites.

Unfortunately, it doesn’t help when the two largest retailers on this planet don’t see eye to eye:

Once again, Apple and Amazon see things differently.

Revealing It All

We hope you liked this article about the differences between check out and checkout.

We have so much more to share with you.

Why Listen to Us?

We’ve spent the last 14 years in our marketing lab 🧑‍🔬 🧪, experimenting on online shoppers. We’ve learned a crap ton and are ready to share those learning.

We want more marketers and CEOs to know about it.

Eventually, we’ll make this into a book. If you want an unfair advantage over competitors now is the time to steal our ideas because once they are published the cat will be out of the bag.

Each chapter in our forthcoming book will feed into the next. Click the link that best describes where you want to start the story:

Chapter 1: is all about conversation rate optimization (CRO). It talks about the history of CRO, statistics of CRO, and describes how most agencies do CRO. We need to describe how most are doing it before revealing our process (that’s the topic of Chapter 4.)

Chapter 2: For every 1,000 product pitches encountered the shopper buys 1️⃣ item (and we’re being generous). If the goal is to have the consumer choose your product we need to understand their selection criteria– we need to understand their buyer psychology. Marketers who nail this will always outrun their peers.

Chapter 3: Conversion optimization work typically focuses on design and layout changes. We don’t limit ourselves to design and layout. Through extensive experimentation, we realized that the thing that moves the conversion needle 🧭 are the words and ideas expressed on the page. Conversion copywriting is where it’s at.

Chapter 4: Marketers make a fatal mistake. They focus on optimizing the whole site. We focus on the tip of the spear. The most important page on your entire site is your product page. To understand why this is, read this post: Product Page Optimization.

Apple’s “Check Out” button is a verb phrase, and thus has a space – equivalent to a button that reads “Go Home”.

Amazon’s “Proceed to checkout” uses checkout as a noun – equivalent to a button that reads “Proceed to aquarium”.

There’s no inconsistency, and both “check out” and “checkout” are correct, depending on verb vs noun usage. There’s no *single* spelling that applies to all contexts.

Now I will jumpoff a bridge.

Please don’t jump off anything. You are right about both being correct.
