The Complete Review-Writing Guide
A good review isn't just "I liked it." It captures a real experience so sellers and future buyers both learn something. With Reviu, one photo gets you started.
1. The photo is half the review
Shoppers care about what the product actually looks like in real life — packaging, texture, size in your hand. Upload a clear photo and Reviu's AI reads color, material, and shape into the copy. Natural daylight gives the sharpest analysis.
- Shoot in daylight so colors stay true
- Combine one wide shot with one close-up detail
- Keep the background simple so the product pops
2. Star rating sets the tone
The star rating is the first thing readers see. Reviu adjusts the voice automatically: 5 stars leans into what you loved, 3 stars stays balanced, 1–2 stars gets specific about what went wrong.
★★★★★ (5)
Warm, positive, hints at repurchase without hype.
★★★ (3)
Honest pros and cons, weighing price against value.
★★ (2) / ★ (1)
Concrete problems (shipping, quality, sizing) so sellers and future buyers can act on it.
3. Platform culture matters
Amazon, Instagram, and a blog all have different review cultures. Reviu ships tuned tones for each one so your review reads native to the platform.
Amazon
Detailed and practical wins. Mention shipping, packaging, and how the product compares to what the listing promised.
Instagram caption
Sensory and specific. Vibes, colors, "everyday" energy — Reviu auto-adds a handful of relevant hashtags.
YouTube comment
Short, casual, viewer-voice. Great for saying "I bought this because of your video."
General
Blog reviews, forum posts, product pages. Medium-length narrative that flows from motivation to use to verdict.
4. Picking a tone
- Honest — balanced pros and cons, no exaggeration. The safe default.
- Warm — friendly and sincere. Great for gifts and home goods.
- Detailed — texture, fit, and finish. Ideal for fashion and beauty.
- Concise — short and to the point. Perfect for quick shopping notes.
- Witty — playful, quotable. Nice for Instagram or short-form video.
5. Steer the AI with keywords
The "keywords" field is the strongest control you have. Type three to five things you want the review to mention — "lightweight, roomy, fast shipping" — and the AI weaves them in naturally. Too many and the sentences get awkward; pick the ones that matter most.
6. Choosing the length
- Short — quick shopping reviews, Instagram captions.
- Medium — Amazon and general product reviews.
- Long — blog reviews, sponsored posts, detailed writeups.
7. Make the AI draft your own
Treat the AI output as a strong first draft. Add one or two sentences from your actual experience, or tweak a detail that only you would notice. Use "Rewrite" to try a fresh variation with the same settings until you find one you like.
