The change
The variant adds a 'Best Seller' label on the top-left of the hero image.

Control
The product page with the main image and no badge on it.
Variant
A small "Best Seller" label placed in the top-left corner of the hero image. The rest of the page stayed the same.
Why it likely won
Our reading of the result, not the practitioner's claim.
- the hero image is the first thing shoppers look at, so the badge is seen before price or reviews.
- "Best Seller" tells shoppers that others already chose this product, which makes it feel like a safe pick.
- a short, clean label on the image is less likely to be ignored than an app sticker near the price.
Caveats: Ranges crossed zero, so the lift is likely but not proven. Sample size and test length were not shared, and the product shown in the post is an illustration, not the tested store.

How to run this test on your store
- Hypothesis
- If we add a "Best Seller" badge to the main product image, then more visitors will buy because they see social proof in the first second.
- Primary metric
- Revenue per visitor
- Guardrails
- Average order value
- Conversion on non-badged products
- Return rate
- Who should test it
- Stores with products that genuinely are top sellers. Don't put it on everything; if every product is a best seller, the label means nothing.
Questions
Do best seller badges increase conversions?
In this test, a "Best Seller" badge on the hero image lifted conversion by 7.04% and revenue per visitor by 7.27%. The ranges crossed zero, so it's a likely win.
Where should a best seller badge go?
Dave Diederen put it directly on the main product image, in the top-left corner, rather than near the title or price.
Does a badge change order value?
Not here. Average order value stayed flat, so the gain came from more people buying.
