What is Benson?
Stop Discount Extensions Stealing Your Margin
Benson shows online stores which coupon extensions and AI shopping agents are in their sessions and what they cost. It names the coupon and cashback extensions shoppers run, and measures what each one does to conversion, order value and discount depth. Merchants can then set rules per extension — hide pop-ups, cap code attempts, or put their own offer in front of shoppers — and test every change against a holdout, so the lift is measured rather than modelled. Benson also tracks attribution integrity, flagging when affiliate or click IDs change late in the funnel. Detection and agent analytics are free on every plan. It connects with one small script on any platform, and paid plans are fixed monthly prices with no commission.

Benson Key Features
Extension detection
Names the coupon and cashback extensions in real sessions and shows what each one costs in conversion, order value and discount depth.
Holdout experiments
Set rules per extension by page, country or device, and compare revenue per session against a holdout before committing.
Pop-up blocking
Hides the pop-ups your rules match before shoppers click, so private codes stay private and cashback pop-ups lose the last click.
Attribution integrity
Records the affiliate and click IDs shoppers arrive with and flags when they change, showing the whole trail to checkout.
Own discount widget
Replace an extension with your own discount widget, with targeting, triggers and unlocks.

Common questions
Benson FAQs
What counts as a session?
One visit to your store by one shopper. A session ends after 30 minutes without activity or after 24 hours, and plan quotas count sessions across all sites in a workspace.
What happens when I reach my session limit?
Nothing breaks on your store. Benson emails you as you approach the limit and again when you reach it, then keeps everything on for another 72 hours so you have time to upgrade.
How does the trial work?
Every new workspace gets 14 days of everything in the Own plan, with no card. When the trial ends you move to Free unless you pick a plan, and your data and settings stay.
Can I cancel or change plans?
Yes, any time from Settings and Billing. Upgrades apply straight away; cancelling or downgrading takes effect at the end of the period you have paid for.
What can Benson do at checkout?
On Shopify, no app can change what an extension shows inside checkout, so Benson hides pop-ups on storefront pages and protects checkout at code level with allowlisted codes.
