Best AI Description Prompts (Copy-Paste Templates for Every Platform)

The quality of an AI-generated description depends almost entirely on the prompt behind it. A vague prompt like “write a description for my candle” produces filler copy you’ll end up rewriting anyway. A specific prompt — one that names the audience, the platform, the tone, and the key details — produces something close to publish-ready on the first try. This guide gives you tested templates for every major platform, plus the reasoning behind why each one works, so you can adapt them to anything you sell.

Why Prompt Structure Matters More Than Prompt Length

A long prompt isn’t automatically a good one. What matters is that it includes four things: the platform (so formatting matches expectations), the audience (so tone lands correctly), the specific details (so the output isn’t generic), and the desired length. Miss any one of these and you’ll spend more time editing than you would have spent writing from scratch.

Etsy Product Prompt

Why this works: Etsy buyers respond to story and emotion before specs. Leading with a hook and only introducing dimensions and materials afterward mirrors how a real Etsy seller would naturally pitch a handmade item — and it matches how Etsy’s own search algorithm weighs descriptive, buyer-intent language over plain product terms.

Amazon Listing Prompt

Why this works: Amazon shoppers are scanning, not reading closely, so short paragraphs matter more than flowery language. Avoiding unverifiable claims (“the best on the market”) also keeps you compliant with Amazon’s content policies, which can flag or suppress listings that make unsupported claims.

YouTube Video Description Prompt

Why this works: The visible portion of a YouTube description (before the “show more” cutoff) is prime real estate — it’s what shows in search results and under the video. Prompting specifically for that constraint prevents the AI from burying your hook three paragraphs down.

Instagram Caption Prompt

Why this works: Instagram truncates captions after roughly 125 characters, so the first line has to function as a complete thought on its own. Asking for exactly one call-to-action — instead of several — also avoids the diluted, “buy now, follow us, check the link” pileup that makes captions feel like ads.

Business “About Us” Prompt

Why this works: Most “About Us” sections ramble because they try to say everything at once. Structuring the prompt around three fixed questions forces a tight, scannable result — which is exactly what a visitor deciding whether to trust your business in the first five seconds needs.

YouTube Shorts / Reels Caption Prompt

Why this works: Short-form video captions compete with autoplay and swipe behavior, not search. The goal isn’t SEO here — it’s stopping a thumb mid-scroll, so length and punch matter more than keywords.

Google Business Profile Prompt

Why this works: Google Business descriptions are read by local searchers deciding between multiple similar businesses in seconds — specificity about what makes you different does more work than generic praise like “best service in town.”

How to Adapt These Templates to Anything You Sell

Every template above follows the same skeleton: platform + audience + tone + specific details + length constraint + one clear action. If you’re writing for a platform not listed here, you can build your own prompt using that same skeleton — the specific platform rules matter less than making sure all five ingredients are present.

A Quick Before-and-After

Vague prompt: “Write a description for my candle.” Result: generic filler about “the perfect addition to your home.” Specific prompt: “Write an Etsy description for a hand-poured soy candle in a reused wine bottle, for eco-conscious gift shoppers, warm and cozy tone.” Result: something you could publish today with minor edits. The difference is always specificity — audience, material, tone, and platform, every time.
