How to complete a hair masks listing on Amazon Spain

The 5 attributes that most set best sellers apart

Sample: 129 best sellers against 200 from the rest of the category, data from 5-Nov-2026.

Your Wintraits Scan Index: what raises it

The Wintraits Scan Index sums up in one number from 0 to 100 how close your listing is to the best sellers'. Each trait adds its weight: more the more it separates best sellers from the rest. The middle half of best sellers scores 33-79; that of the rest, 22-48.

Best sellers 33-79Rest 22-48

If we can't read a trait from your listing, it counts neither for nor against: the index uses the ones that can be read.

Attribute by attribute

Repite el nombre de marca dentro de las viñetas

77% of the best sellers have it, against 39% of the rest. We read it from the text and data of the listing of each product in the sample.

• Common mistake: Putting it in the listing when your product does not really meet it.

More than 5 images

64% of the best sellers have it, against 33% of the rest. We count the images in the listing. Above the threshold, the listing usually shows more than the main photo: details, size, use and information.

• How it looks in a listing: Main photo on a white background, product in use, close-up of the texture or material, size next to a reference, ingredients or specifications, and what is in the box.
• Common mistake: Uploading several near-identical images to reach the number: each image should answer a buyer’s question.

Alguna viñeta tiene más de 150 caracteres

55% of the best sellers have it, against 26% of the rest. We read it from the text and data of the listing of each product in the sample.

• Common mistake: Putting it in the listing when your product does not really meet it.

Description over about 690 characters

65% of the best sellers have it, against 40% of the rest. We count the characters in the description. An empty description does not count as short: it is usually A+ content, which we cannot read.

• How it looks in a listing: One paragraph per topic: what it is, how to use it, what it contains or is made of, who it is for and what is in the box.
• Common mistake: Copying the bullet points word for word or padding the text: length only helps the buyer if it adds new information.

Has 5 bullet points or more

57% of the best sellers have it, against 33% of the rest. We count the bullet points, the key points shown next to the title.

• How it looks in a listing: One bullet point per idea: main benefit, how to use it, ingredients or materials, who it is for and what is included.
• Common mistake: Leaving bullet points empty, or writing five that say the same thing in different words.

Listing checklist

Title

• No clear differences here in this category.

Bullet points and description

• “Description over about 690 characters”: if your product has it, make it visible in the bullet points and description.
• “Has 5 bullet points or more”: if your product has it, make it visible in the bullet points and description.

Images and video

• “More than 5 images”: if your product has it, make it visible in the images.

What you say about the product

• “Repite el nombre de marca dentro de las viñetas”: if it is true of your product, say it in the title or the first bullet points.
• “Alguna viñeta tiene más de 150 caracteres”: if it is true of your product, say it in the title or the first bullet points.

Only include what is true of your product: this describes today's sellers, it does not say what will make yours sell.

How to use this guide, step by step

1. Open your listing next to the attribute table.
2. Check which ones it already has. For the title, bullet points and description you can use the quick check, free and without saving anything.
3. If your product has an attribute but it does not show, add it where the checklist says.
4. Change one thing at a time and note the date, so you know what changed your results.
5. Come back when we update the category: best sellers change.

At what price?

Best sellers tend to be below €21.45: 31% of them are above it, against 68% of the rest.

Common mistakes

• Copying a best seller’s listing: this data says which traits recur, not which text works.
• Adding traits your product does not have: returns, bad reviews and Amazon warnings follow.
• Changing everything at once: if you change one thing at a time and note the date, you will know what moved your sales.
• Relying on a single trait: best sellers usually combine several, and many were already big before they had it.
• Forgetting what depends on the shop (who sells, variations, brands with several products): it also sets best sellers apart, but it is not fixed in the listing.
