Shopify app · collection sorting and merchandising

Collection sorting you can explain

Paceline puts every collection in a sensible order: in stock first, preorders where you decide, sale and best sellers up, sold out last. Every move has a reason you can see, every run can be undone. Scout suggests SEO-ready collection pages, and shoppers who opt in get a personal first page.

Merchandising rules instead of dragging products by hand

Stock, done right

Choose which locations count, where preorders go and how untracked items behave. A variant in stock is never hidden by negative stock elsewhere.

Rules per collection

Shop rules with per-collection overrides: best sellers for a period, brand balance, scheduled promotions, pinned products.

Preview and undo

See the new order with a reason next to each product before anything changes. Every run keeps a snapshot.

SEO-ready edits by Scout

Scout reads your catalog and suggests collection pages like “Women's gravel bikes” with clean URLs, titles and intros.

Personal first page

Shoppers who opt in see their kind of products first. Filters always win; pages after two stay the same for everyone.

Analytics and A/B tests

Views, clicks, adds to cart and revenue per edit, and A/B tests that show no winner until the data is enough.

Questions merchants ask

Does Paceline replace my collection page or filters?

No. Paceline writes the order to Shopify itself, so your theme, filters and pagination work exactly as before.

What happens to preorders and untracked products?

You decide: preorders right after in-stock products or at the end, untracked products counted as in stock or not.

Can I undo a change?

Yes. Every run keeps a snapshot of the previous order, and you can roll back in one click.

How does the personal first page work?

Only for signed-in shoppers who choose what they like. Their choice is saved in their customer record in your store. We keep no shopper data.

How often does it re-sort?

After product and stock changes (with a short pause so bursts are combined) and every night at 03:00 in your store's time zone.
