What Benson does

See every extension

Benson names the coupon and cashback extensions in your sessions and shows what each one costs.

Test before you block

Set a rule for each extension and compare revenue per session against a holdout.

Keep your margin

Hide the pop-ups you don't want, so your codes stay yours and the last click stays honest.

Measure first, then decide what to stop

Measure every extension

Benson spots every coupon and cashback extension in real sessions, on the pages where they act. See what each one does to conversion, order value and discount depth, and who took the credit.

  • Every extension, by name
  • Conversion and order value
  • Discount depth
  • Affiliate credit

Experiment with rules

Some extensions bring you sales. Others take commission on orders you already had. Set rules for each one by page, country or device, and test them against a holdout before you commit.

  • Rules per extension
  • Observe before you block
  • A holdout behind every switch

Block the pop-ups

Benson hides the pop-ups your rules match before shoppers click, so your private codes stay private and cashback pop-ups don't get the last click.

  • Pop-ups hidden by rule
  • A cap on code guessing

Follow the money. See who takes the credit before checkout.

  • Hijack detection

    Benson records the affiliate and click ids every shopper arrives with, and flags when they change.

  • The whole trail

    Where the shopper came from, what touched the cart, and where the credit went after it.

  • Every session, mapped

    Red means the credit changed with an extension in the session.

  • Code attempts

    See how many codes AI agents and automation try, and cap them per visit.

  • Commission moved

Connect your store in two minutes, with one snippet. A day to know.

The script is about 2.5KB and loads after your page. Your first extension sightings stream in as shoppers browse.
  1. Connect your store

    One snippet in your store's head, on any platform. The Shopify app is coming soon.

  2. Watch it go live

    The install checks itself in real time, and sightings start streaming in.

  3. See, stop or own

    Keep watching, hide the pop-ups you don't want, or put your own offer up.

  4. Keep score

    Each switch can run against a holdout, so the lift is measured, not modelled.

The lift you see is real. Holdouts show the difference Benson makes.

  • Holdouts, one switch away

    A slice of extension traffic runs without Benson, so every lift is measured against shoppers it left alone.

  • Revenue per session, not vanity counts

    Pop-ups hidden is a count. Revenue per extension session, protected versus control, is the result.

  • Ranges, not flattering numbers

    Every holdout result comes with a confidence interval, so a small store sees an honest range and a big one sees how tight it is.

  • Take it to your network

    Hand the attribution report to your affiliate network, or export the numbers for your finance team.

Your other apps say they lift sales too. Check them the same way.

Move reviews, chat or trust badges into Benson, load each one only where it pays, and hold it back from some shoppers to see what it adds.
  1. Paste the vendor's code

    Benson shows what it will load and what stays in your theme.

  2. Only where it pays

    Paid traffic, a country, product pages, the evening. Each rule reads back as a sentence.

  3. One verdict at the end

    A random share goes without it. Then Benson checks the vendor's claim against your orders.

Fair questions from merchants, answered

“We don't get extension traffic.”

Maybe. Benson will tell you in a day, from your own sessions.
