Does Benson load apps on checkout?

Never. Benson won't load an app on checkout, payment or password pages, or on any page with a card number field.

Will it slow my store down?

Apps load only on the pages and visits your rules choose, so the pages they don't help carry fewer scripts. Apps nobody needs straight away, like a chat button, can wait until the page has loaded.

What about cookie consent?

Each app waits for the consent it needs. Benson reads your banner, whether that's Shopify's, Google Consent Mode, an IAB TCF banner or the WP Consent API on WooCommerce, and loads the app once the shopper agrees.

Which apps can move into Benson?

Any app installed with a script tag, from any vendor. App blocks you add in Shopify's theme editor stay in your theme.

Can I load ad pixels and analytics through Benson?

Yes, by rules like any other app. Their value shows up in your ad platforms and analytics, so that's where you judge them.

Can I switch an app off quickly?

Yes. Switch it off in Benson and it stops loading within about a minute, with no theme edit.

Tools

Every app promises a lift. You can't tell which ones deliver.

Reviews, live chat, trust badges, discount checks, upsell pop-ups: each one arrived with a case study and a monthly bill. Benson loads every app only where it pays, and measures what it adds on your own shoppers.

A reviews app shows a lift in conversion. A chat widget shows bigger baskets. Each pitch was measured on someone else's store, and each one sounds worth a monthly fee.

What most teams try

You could take the vendor's word for it. Their report often counts the shoppers who used the app, not the sales it added.
You could switch an app off for a month. Promotions, seasons and ad spend change in the same month, so the difference isn't only the app's.

Or you could run every app through Benson.

Load each one only where it pays, hold it back from a random share of shoppers, and get one answer at a planned end, from your own orders.

Sound familiar?

Three ways your app stack costs you.

The problem
Every app loads everywhere.
The theme tag fires on every page, for every shopper, even where the app does nothing for the sale.
The fix
Run it only where it pays.
Paste the vendor's code into Benson and choose who gets it: paid traffic from Google, Meta, Microsoft or TikTok, affiliate clicks from Awin, Impact, CJ or ShareASale, a country, product pages, the evening.
Sample store
Where it loadsMatch all ofCountryUnited KingdomMatch any ofTrafficPaid · GoogleTrafficAffiliatePagesProduct pagesLoads forCountry is United Kingdom and (Traffic is paid from Google or Traffic is affiliate), on product pages
The problem
The vendor marks its own homework.
Their case study comes from other stores, and often compares shoppers who chose the widget with shoppers who didn't.
The fix
Hold it back, and check the claim.
A random share of shoppers goes without the app for a fixed length. At the planned end, Benson gives one verdict, checks the vendor's claim and puts a monthly figure on it.

The problem
Renewal day, and nothing to show.
The invoice lands, and nobody can say which orders the app was part of.
The fix
Your orders record the apps that were on.
In your Benson orders, on the Shopify order as a cart attribute, and in the dataLayer for your analytics. When the renewal lands, you have the orders.

How it works

Moving an app takes three steps.

Any app installed with a script tag, from any vendor. Benson loads only what you give it and never touches anything else on your store.

Step-by-step guide

Sample store

Paste your vendor's code

<script>
  window.reviewsConfig = { shop: "your-store" };
</script>
<script src="https://widget.reviews.example/loader.js" data-shop="your-store" async></script>
<div id="reviews-badge"></div>

Attributes Benson dropsNone

1
Copy the install code
From the vendor's install instructions, or your page source: the whole snippet, as they give it.
2
Paste it into Benson
Benson lists the domains and scripts it will load, and anything that stays in your theme.
3
Take it out of your theme
Switch the app on in Benson, then remove the theme's copy. Benson tells you if one is still loading.

Prove it

Peeking picks false winners. Benson decides once.

A random share of shoppers goes without the app for a fixed length. Both groups shop through the same weeks, so the difference comes down to the app.

How measuring works

Sample store

How many shoppers to hold back, and for how longAbout 1,643 shoppers a day match its rules. More held back, or longer, sees smaller changes.Hold back 10%14 days34.1%smallest change it can see28 days24.1%smallest change it can see56 days17.1%smallest change it can see120 days11.7%smallest change it can seeRecommendedHold back 50%14 days20.5%smallest change it can see28 days14.5%smallest change it can see56 days10.2%smallest change it can see120 days7.0%smallest change it can see

Know what your traffic can prove

Before you hold anyone back, the planner shows the smallest change each option can see on your store's last 28 days, so you never run a test that can't answer.

Decided once, no peeking
Check after every visitor and stop at the first good result, and a change that does nothing can win 26.1% of the time instead of 5%. Benson fixes the length up front.

The vendor's claim, checked
Add the lift the vendor quotes. Benson compares everyone it loaded the app for with everyone it held it back from, and tells you whether the claim holds up.
A breakage alarm
While a measurement runs, Benson watches for revenue per visitor falling with the app on, and emails you if it does.
Where it helps
Results split by traffic, device and time of day point to where an app earns its keep, one click from a new rule.

Questions

The planner shows what your traffic can prove before you hold anyone back, so you never run a test that can't answer. Hold back more shoppers, or for longer, and it sees smaller changes.
