Where collection pages leak revenue

Most Shopify collection pages bury the right products. Shoppers land, scan, and bounce before they ever reach a product page.

Shoppers can't narrow the range

No useful filters, or filters that reload the whole page and lose scroll position, so people give up instead of drilling in.

Best-sellers sit below the fold

Default sort buries proven products behind slow movers and sold-out lines, so your strongest sellers never get seen.

Deep catalogues, flat hierarchy

Hundreds of SKUs in one endless grid, with no sub-collections or landing structure to guide intent.

Thin, unlinked collections

Collections that don't link to related ranges, so shoppers hit a dead end and search engines can't crawl the depth.

Slow, janky grids on mobile

Heavy images and layout shift on the grid where most traffic lands, costing you the add-to-cart before it happens.

No merchandising control

You can't pin, boost or hide products by collection, so seasonal and margin priorities never surface.

Scope: included vs your side

Where our work stops and yours starts, agreed at discovery.

We handle	Your side	Out of scope
Merchandising	Sort logic, pin/boost/hide rules, card layout	Choosing priority and seasonal products	New product photography
Filtering & search	Facet build, config and scroll behaviour	Confirming the filter taxonomy	Replatforming search to a new engine
Hierarchy & linking	Sub-collections, internal links, indexable URLs	Approving the collection structure	Full information-architecture redesign
Measurement	GA4 events and before/after reporting	Analytics access and goals	Multi-touch attribution modelling

Is this the right fit?

A fit if

You run a Shopify or Shopify Plus store with 100+ SKUs across multiple collections.
Traffic reaches your collection pages but add-to-cart from them is flat.
You want merchandising and filtering your team can control without a developer.
You've got GA4 or similar in place to measure the lift.

Not a fit if

You have a handful of products and no real collection structure to optimise.
You're pre-launch with no traffic or sales data yet, start with a build.
You're on another platform. We're Shopify-only.
You want a guaranteed percentage lift with no discovery or testing.

How a collection page engagement runs

Discovery & audit, week 1

We review analytics, session recordings and your top collections to find where visitors drop off.

Merchandising & filter plan, week 1–2

We agree the sort logic, filter taxonomy, hierarchy and internal-linking map with your team.

Build & configure, week 2–4

We build filtering, merchandising rules, card design and a responsive grid on your theme.

QA & accessibility, week 4

Cross-device, cross-browser and WCAG 2.1 AA checks on the grid, filters and pagination.

Launch & instrument, week 5

We ship, wire GA4 events on filter, sort and add-to-cart, and baseline the numbers.

Measure & iterate, week 5–6+

We read the data, refine merchandising and hand over a report with prioritised next steps.

Quality controls on every launch

The checks we run before anything goes live.

WCAG 2.1 AA on grid, filters and pagination

Collection page optimisation FAQs

You do. All theme code, merchandising rules and configuration live in your Shopify store and are yours to keep.

A focused tune-up runs 3–4 weeks; a full collection optimisation across the catalogue is typically 5–6 weeks after discovery.

Yes. We work with your current stack. If a filtering or search app is already in place, we configure it rather than rip it out unless there's a clear reason to change.

Whichever fits. Shopify's Search & Discovery covers many stores; for complex facets we use a vetted app. We recommend based on your catalogue, not a kickback.

No, it helps. We keep collection URLs indexable, handle pagination and canonicals correctly, and add internal links that let search engines reach deeper ranges.

We baseline before launch, then track add-to-cart, revenue per session and collection bounce via GA4 events on filter, sort and add-to-cart.

You get a report, the event tracking and a prioritised next-steps list. Many clients move to an ongoing merchandising retainer to keep iterating.

Yes. We set up rules and metafields so your team can pin, boost, hide and re-sort products by collection without a developer.

No. This works on your existing Shopify theme. If the theme is holding you back we'll say so, but most gains come from merchandising, filtering and structure.
