Description Quality
How Vantage scores your product descriptions — word count, factual content, structure, and tips to improve
Last updated: 6th June 2026
Description Quality
Weight: 16.7% — One of the three highest-weighted dimensions. Your product description is where AI shopping agents gather the detailed information they need to match products to shopper queries.
What Vantage checks
Vantage evaluates four aspects of every product description:
Word count (25 points)
Descriptions need enough depth to be useful but shouldn't be padded with filler.
| Word count | Points | Why |
|---|---|---|
| 150-300 words | 25 | Ideal — thorough without being excessive |
| 100-149 words | 18 | Good but could include more detail |
| 300-500 words | 18 | Solid depth, may include some excess |
| 50-99 words | 10 | Light — missing important details |
| Under 50 words | 0 | Too thin for AI agents to work with |
Factual content density (25 points)
AI agents prioritize facts over feelings. Vantage measures the ratio of factual content in your description — things like numbers, units of measurement, materials, and technical specifications.
- High factual density (5% or more of words are factual): 25 points
- Moderate factual density (3-5%): 15 points
- Low factual density (under 3%): 5 points
Attribute density (25 points)
Vantage looks for mentions of concrete product attributes: material, dimensions, weight, color, use case, compatibility, and more. Each attribute found earns 5 points, up to a maximum of 25 points.
Structure (15 points)
How your description is formatted matters. AI agents parse structured content more reliably.
| Format | Points |
|---|---|
| Paragraphs and bullet points combined | 15 |
| Only paragraphs or only bullets | 10 |
| Unstructured wall of text | 0 |
Low marketing fluff (10 points)
Similar to titles, descriptions are penalized for excessive marketing language. Keeping the hype-to-fact ratio low earns you the full 10 points.
Tips to improve
- Write 150-300 words. Cover what the product is, what it's made of, how it's used, and who it's for.
- Lead with facts. Dimensions, materials, weight, and compatibility should appear in the first paragraph.
- Use bullet points for specs. A specs section with bullets is easy for both humans and AI to parse.
- Mention 5+ attributes. Material, dimensions, weight, color, and use case is a solid starting set.
- Cut the fluff. Replace "This incredible product will change your life" with "This 12oz stainless steel tumbler keeps drinks cold for 24 hours."
Before and after
Poor description:
"You'll love this amazing product! It's the best thing ever and perfect for everyone. Buy now and you won't be disappointed!"
- 23 words — far too short
- Zero factual content
- No attributes mentioned
- Pure marketing fluff
- Score: ~5/100
Good description:
"The Hydro Flask Wide Mouth Water Bottle holds 32oz of your favorite beverage and keeps it cold for up to 24 hours or hot for 12 hours. Made from 18/8 pro-grade stainless steel with a powder-coated finish for durability and grip.
Features:
- 32oz capacity
- Double-wall vacuum insulation
- BPA-free and phthalate-free
- Dishwasher safe
- Fits most car cup holders
Perfect for hiking, gym sessions, or daily commuting. The wide mouth opening makes it easy to add ice cubes and clean."
- 89 words — could be longer, but packed with facts
- Strong factual density (numbers, materials, specs)
- Multiple attributes mentioned
- Combined paragraph and bullet structure
- Score: ~82/100
Common mistakes
- Empty or near-empty descriptions. Even a few sentences score dramatically higher than nothing.
- Copy-pasted marketing emails. Promotional language doesn't help AI agents understand what the product actually is.
- Wall of text. Break descriptions into paragraphs and bullet points for better parsing.
Quick win: add a bullet-point specs section to every product. Even 5-6 bullets with material, dimensions, weight, and key features can push your Description Quality score above 70.
