Quick answer: Amazon conversion (Unit Session Percentage) typically runs higher than general ecommerce — often cited around 10–15% overall — but the honest range is 5% to 30%+ depending on category. Consumables convert high, considered purchases convert low. The only benchmark that matters is your own trailing rate for each category you sell in.
"Is my conversion rate good?" is one of the most-asked and least-answerable questions in Amazon selling, because the number that counts as good depends almost entirely on what you sell.
How Amazon defines the number
Amazon's conversion metric is Unit Session Percentage: units ordered divided by sessions. Two things to keep straight:
- It's units, not orders. A shopper who buys three of an item in one session contributes three to the numerator. In multi-pack or low-cost repeat-buy categories, this alone inflates the rate relative to an orders-based conversion figure.
- It's session-based, not page-view-based, so it isn't distorted by variation click-throughs.
You'll find it per ASIN in the Sales and Traffic report, with a separate B2B column — the report guide covers where.
Why Amazon runs hotter than other channels
A typical ecommerce site converts somewhere around 2–3%. Amazon routinely runs several times that, and the reasons are structural: shoppers on Amazon are usually in buying mode rather than browsing, Prime removes shipping-cost and delivery-time friction at checkout, payment details are already stored, and reviews do the trust work that a standalone store has to earn. So a rate that would be exceptional on a Shopify store can be mediocre on Amazon.
The category spread
Rough, directional ranges people report — treat these as orientation, not targets:
| Category type | Rough conversion band | Why |
|---|---|---|
| Consumables, groceries, replenishables | 20–35% | Habitual repurchase, low deliberation, multi-unit orders |
| Health, beauty, household basics | 12–25% | Frequent need, moderate deliberation |
| Toys, books, small home goods | 10–20% | Impulse-friendly, low price risk |
| Apparel, shoes | 8–15% | Size uncertainty, high return intent suppresses purchase |
| Electronics, appliances | 5–10% | High price, heavy research, cross-shopping |
| Furniture, large/considered goods | 3–8% | Big commitment, long consideration cycle |
A 9% rate is a warning sign for a supplement and a strong result for a standing desk. Benchmarking against a blended "Amazon average" tells you almost nothing if your catalog skews to one end.
Set your own benchmark
The workable approach:
- Group your ASINs by category type, not by your internal product lines.
- Pull 90 days of Unit Session Percentage per ASIN from the Sales and Traffic report.
- Take the session-weighted average within each group — weight by sessions so a 40-session ASIN doesn't swing the benchmark the way a plain average would. This is the same weighting logic that keeps a blended Buy Box percentage honest.
- That group average is your benchmark. An ASIN sitting well below its group's rate is the one to investigate.
Now the number is actionable: not "is 11% good" but "this ASIN converts at 7% while its category group averages 14%, so something specific is wrong with this listing."
What pulls a rate below its category
When an ASIN underperforms its group, the usual causes, roughly in order of how often they're the problem:
- Losing the Buy Box — shoppers who can't click the main "Add to Cart" convert far worse. Check the Buy Box diagnostic.
- Price above the field — even a small premium against near-identical offers drags conversion.
- Weak main image or title — the two things a shopper judges before clicking.
- Traffic quality — broad or mistargeted ad terms bring browsers, not buyers; watch page views per session for the tell.
- Review deficit — fewer or lower-rated reviews than the competitors on the same search results page.
- Out of stock recently — conversion takes time to recover after a lapse.
One seller spent a month rewriting bullet points on a listing converting at 6% before checking that it had quietly fallen to a 40% Buy Box share. The copy was never the issue. Rank the likely causes before you act on any of them.
The B2B check
If a business might buy your product, read the Unit Session Percentage – B2B column separately. B2B traffic often converts at a different rate, and a healthy blended number can hide a B2B conversion gap — or a B2B segment worth pricing for. Business Reports vs Brand Analytics covers where the B2B view fits.
EcomSanity tracks conversion per ASIN in session-weighted terms, so you can compare each listing against its real peer group instead of a meaningless site-wide average. See tracking conversion rate by ASIN for the method, and what's a normal Amazon review rate? for the same benchmarking approach applied to reviews.
Frequently asked questions
What's a good conversion rate on Amazon?
There's no single number. Amazon overall converts much higher than most ecommerce because shoppers arrive with intent, and figures in the 10-15% range get cited as typical. But consumable and replenishment categories can run 25%+ while considered purchases like furniture or electronics sit closer to 5-8%. Your benchmark is your own trailing rate, by category.
Why is my Amazon conversion rate lower than the numbers I see quoted?
Usually category mix, traffic quality, or price competitiveness. Broad ad terms, a weak main image, losing the Buy Box, or being priced above the field will all pull the rate down regardless of category.
How is Amazon conversion rate calculated?
Amazon reports it as Unit Session Percentage: units ordered divided by sessions. Note it's units per session, not orders per session, so multi-unit orders can push it above what an order-based rate would show.
