Product page

Popup upsell

Add-to-cart

The Popup Upsell fires immediately after a customer adds a product to their cart from the product detail page. It catches them at peak buying intent — a few seconds before they move on — and offers a relevant follow-up purchase as a focused overlay.

Three layouts cover the three psychological angles: a single hero recommendation (Cross-sell), a curated mini-bundle (FBT), or a multi-select add-on list (Add-ons). Each fires from the same Add-to-Cart event but targets a different shopper mindset.

Layouts

Cross-sell Popup

Single product

Opens after Add-to-Cart with one recommended product and a clear Add button. Designed for low-friction acceptance — one decision, one click.

Captures attention at peak buying intent — the moment after a successful Add-to-Cart.
Picks one product at a time — minimal decision fatigue.
Customer can dismiss without losing the cart.
Configurable position: center, corners, full-screen.

Expected AOV impact: 5–12% AOV lift on add-to-cart events, with acceptance rates around 8–18% on relevant pairings. The single-product format converts highest of the three popup layouts.

Best for: Stores with a clear hero accessory or premium variant that pairs with most products (case for phones, premium edition for vinyl, gift box for jewelry).

FBT Popup

Bundle

Popup version of FBT — trigger product and recommended items shown together with checkboxes, a live total, and a single Add button.

Bundle psychology in a focused overlay — no PDP layout changes needed.
Live total updates as customer ticks boxes, with discount preview.
Optional automatic bundle discount applied through Shopify Functions.
Works without modifying the product page layout.

Expected AOV impact: 8–15% AOV lift on add-to-cart events. The bundle savings narrative paired with Add-to-Cart timing pulls higher per-event revenue than a single cross-sell.

Best for: Categories with strong complementary pairings (skincare routines, camera + lens + bag, kitchen appliances + accessories).

Add-ons Popup

Multi-select

Checkbox list of add-on products shown after Add-to-Cart — typically warranty, gift wrap, samples, expedited shipping. Multi-select with one click.

Perfect for accessories, protection plans, and small-ticket extras.
Multi-select via checkboxes — adds 2-3 items in a single click.
High AOV lift on hard goods and apparel where extras get forgotten.
Customer adds extras without leaving the page or revisiting the PDP.

Expected AOV impact: 6–14% AOV lift on add-to-cart events. Lower per-event acceptance than cross-sell, but high attach rate and incremental margin (warranty / gift wrap have very high markup).

Best for: Hard goods, apparel, electronics — anywhere small extras (gift wrap, warranty, expedited shipping, samples) are commonly forgotten.

How it differs from Cart Popup

The Popup Upsell fires from the Add-to-Cart event on a product page. The Cart Popup fires from the Checkout click on the cart page or drawer. Both share the same three layout patterns but target different moments in the funnel.

Position & frequency

9 positions: center, top-left/center/right, middle-left/right, bottom-left/center/right.
Show-once-per-session by default — returning customers see a fresh trigger after their session expires.

How to install

Create a Popup campaign and pick the layout (Cross-sell, FBT, or Add-ons).
Set the trigger products / collections that should fire the popup on Add-to-Cart.
Add the Summer: Popup Upsell block to the product template.
