Writing for the Amazon.com Marketplace

The US marketplace accounts for over 80% of English-language ebook sales globally. American readers expect punchy, direct descriptions that get to the point fast. On Amazon.com, the average reader spends just 8 seconds scanning a description before deciding whether to read more or bounce — so your first two sentences carry enormous weight.

For US authors using Amazon A+ Content (available to brand-registered sellers), your book description works alongside enhanced visual content. A+ Content lets you add comparison charts, images, and formatted text modules below the standard description. When writing your description, assume some readers will also see your A+ Content and focus the description on emotional hooks rather than repeating factual details that appear in your enhanced content.

Amazon.com's bestseller categories have the most competition of any marketplace. Your description should include genre-specific tropes and language that US readers actively search for. Romance readers look for 'enemies to lovers', 'slow burn', and 'second chance romance'. Thriller readers respond to 'pulse-pounding', 'twist ending', and 'unputdownable'. Our AI understands these genre conventions and incorporates them naturally.

US tax considerations affect your pricing strategy, which in turn affects your description approach. At the $2.99-$9.99 sweet spot for 70% royalties, your description needs to justify the price point. For books priced at the higher end ($7.99-$9.99), include social proof elements like 'from the bestselling author of...' or '100,000+ copies sold' if applicable.

KDP's 7 keyword slots on Amazon.com support up to 50 characters each. Use these for terms readers search but that don't fit naturally in your description — competitor book titles, niche subgenre terms, and reader demographics. Our tool generates keywords specifically optimized for US market search patterns.
