It's live in about a minute.
Pick a search query or a category and the real product grid loads — photos, titles, prices, sold-out and discount badges, exactly as shoppers see it. Drag products into position, hide the ones you don't want, restore them later from a tray. No product IDs, no code, no developer.

Search and category pages
Covers both surfaces. For fashion retailers, the category page is where merchandisers spend their time arranging seasonal grids.
Saving is publishing
No separate publish step — changes reach the storefront in about a minute.
The preview is the live result
Admin and storefront build their query through one shared module, enforced by an automated test, so what you arrange is what shoppers get.
Pin without breaking filters
Pinned products hold their position while everything else keeps ranking normally — pinning decides order, not membership, so a pinned product still respects the category's own filters.

Shopify collection strategies
Give your best products the right position.
Rank your collections with sales, stock and engagement. Mix 18 signals with campaign pins, new arrivals and availability rules — then compare photos and titles before publishing the order directly to Shopify.
Start with a draft. Enable each collection when you’re ready, keep its order updated automatically, and restore the original order when needed.

Indexa Intelligence
Your store’s signals. A considered order.
Add an optional learning layer to your collection strategies. Intelligence uses mapped catalog features, Shopify sales history and Indexa events to train a model for your store, with versioned checkpoints you can review and roll back.
Your rules build the candidate order. Intelligence compares a bounded set of leading products while preserving pins and commercial constraints. See what moved, inspect the comparisons and inputs, and decide when to publish.
