How do I set up Best Seller recommendations?
The Best Seller strategy recommends your store’s top-selling products, computed from your real sales data — a self-updating “what everyone’s buying” block you can place on any surface.

Before you start
Sledge Core must be enabled on your theme. Sledge Core is the app embed that loads Sledge on your storefront — without it, nothing you configure here reaches your customers. You enable it during onboarding (Enable in theme), or any time via Online Store → Themes → Customize → App embeds → Sledge Core. Which pages actually show this feature is controlled by its own Surfaces section, explained below.
Open the campaign
Go to Sledge → Tools → Product Recommendation and click Add, then pick the Best Seller strategy — or open an existing campaign of this strategy from the list. All recommendation strategies share the same campaign form; the sections below walk through it with this strategy’s specifics.
Campaign name and Discount
Campaign name is internal — customers never see it. The Discount card can attach an offer to the recommended products: pick the discount type and value, and optionally show the compare-at price so the saving is visible on the card.
Strategy Structure

- Select display — Single shows one recommendation block; Multiple lets you stack several strategies in one placement.
- Strategy — set to Best Seller; this is the logic that picks the products.
- Title — the heading customers see above the block (“Best Seller”). The </> toggle accepts dynamic values, and Add description puts an optional line under it.
- Suggestion source — Display best selling product based on your store data keeps the list automatic, or Add products manually pins your own selection.
Layout

How the block renders on your storefront: Slider (a horizontal carousel) or Grid. Total products caps how many products the block shows in total, and Products per slide sets how many are visible at once in the slider.
Surfaces

Each surface has its own switch: Homepage, 404 / Not Found Page, Collection Page, Product Page, Search Page, Instant Search, Cart Page, and Cart Drawer. Surfaces with placement options expand when enabled — Collection and Search pages let you choose At top or At bottom, Collection Page adds collection targeting, and Search Page can be limited to specific keywords.
Design, Status, and Preview

Design styles the block heading — font size, alignment, transform, and colours for title and description. Status (Enable/Disable) controls whether the campaign is live, and the Preview panel renders the block with your real store data. Click Save in the save bar to apply.
Result
Everywhere the campaign is enabled, customers see a “Best Seller” block filled with your genuine top sellers — the preview below is the live render with this store’s data:

Not showing up? Give the change a minute to sync, then reload the page. Also confirm the campaign’s Status is Enable, the surface you expect is switched on in Surfaces, and Sledge Core is enabled as described above.
