Every ecommerce marketplace has its unique quirks. And while copywriting guidelines are often generalized as SEO best practices—make no mistake that each marketplace has its own rules of engagement.

In this blog we'll cover requirements and recommendations for getting your products listed properly on each channel. Make sure to check out our guide for images if you haven't already and bookmark, print or download this page for easy reference later on.

Content Requirements by Channel

<div id="amazon"></div>


With the lion's share of the U.S. ecommerce market, Amazon is getting more and more strict with its listing requirements to limit the chances of messy, spammy or inauthentic content. There are already 1.1 million U.S. sellers (and counting) on its marketplace. To compete, you'll want to make sure that your copy meets all the standards and is optimized for Amazon's A9 algorithm specifically.

Keep in mind that aside from the below standards, Amazon tends to favor products with a high click-through rate, positive product reviews and high conversion rates. Many sellers will therefore leverage Amazon ads to some capacity to kickstart the flywheel effect and get the momentum going.

Walmart Marketplace

As now the second largest online retailer in the U.S., Walmart is turning heads with its fast-growing marketplace. More and more sellers are lining up for access. Meanwhile, the company maintains that its ambitions are different from that of Amazon; instead of partnering with every seller, it's looking to partner with the right sellers.

This sets the tone for many of its policies, from its application process to its listing standards. Make sure you follow the below guidelines to stay listed and study Walmart SEO best practices to get your products ranking.

<div id="ebay"></div>


Though it lost its second-place title to Walmart, eBay is still a vital channel for many multichannel sellers. With a loyal following of hobbyists and everyday buyers looking for a good deal (especially in categories like clothing, cell phones, home/garden, and sports goods), eBay won't be going away any time soon.

That being said, the marketplace is a mixed bag of at-home sellers and brands, like adidas. To stand out, you'll want to make sure that your listings offer as much detailed and authentic content as possible, and speak to the values of eBay consumers.
