Filter, Sort & Search Tests on Collection Pages: 21 Examples, 4 Results

All 4 measured filter and category navigation tests on collection pages won. The most useful pattern: put ways to narrow the catalog right at the top of the grid and keep them in view.

Oliver Kenyon's Best Sellers and New Drops filter tags won +$82,542/month, and Dave Diederen's image-based category slider added $161K in revenue across 158,691 visitors.

There are no losing tests here, and four results is a small base. The 17 ideas below mostly suggest the same direction.

Why filters and search matter on the collection page

The collection page is where shoppers with a rough idea go to find a specific product. In a large catalog, a shopper who can't narrow the grid quickly tends to leave, so filters, category links and sort options do much of the selling here.

Measured results

Filter tags and filter bars

Oliver Kenyon ran two filter tests. Filter tags such as Best Sellers and New Drops won +$82,542/month. A floating filter bar that stays in view won +$68,584/month.

Image category navigation

Dave Diederen added an image-based category slider to a collection page. It produced +$161K in additional revenue over 1,612 orders and 158,691 visitors.

Filters inside a wider banner change

Dave also added a collection banner with social proof, an offer with a countdown, a description and category filters. It won up to +6% conversion rate and +6.4% revenue per visitor, but the filters' own share is unknown.

Losing or flat tests

None of the four lost. Two practitioners ran all of them and three report revenue rather than conversion rate, so this is a short list of things worth testing, not proof that filter changes usually win.

Untested ideas

Most of the 17 ideas come from Kasper Dolk and Dave Diederen, and they cluster around three themes:

  • Category navigation at the top: Instagram-story style category bubbles, horizontal collection tabs, and subcategory links above the grid for large catalogs.
  • Better filters: filters built on the criteria shoppers use for that product type (size, color, storage), topic filters such as sleep, focus and mood, filters that stay sticky on mobile, and applied filters shown with a way to remove them.
  • Easy switching: a collection switcher and a grid-size toggle so shoppers can see more or fewer products per row.

Placement and design patterns that won

  • Shortcut filters (Best Sellers, New Drops) at the top of the grid.
  • Filters that float or stay visible while scrolling.
  • Categories shown as images, not just text links.

All three patterns cut the work of finding the right subset of products, which is the common thread in the ideas too.

Related tests elsewhere on the store

The same idea won on the homepage: see homepage filter and category tests, where hiding a category slider lost. Also see search in navigation menus, the full filters and search collection and collection page product card tests.

Questions

Do collection page filters increase conversions?

All four measured tests here won. Oliver Kenyon's filter tags won +$82,542/month and a floating filter bar won +$68,584/month. With only four tests and no losses shared, treat filters as a strong test rather than a sure win.

Should filters be sticky on collection pages?

Oliver Kenyon's floating filter bar won +$68,584/month. Dave Diederen suggests sticky filters on mobile for big catalogs, though that idea has not been measured here.

Is an image category slider worth testing on a collection page?

Dave Diederen's image-based category slider produced +$161K in additional revenue over 158,691 visitors. On the homepage, Dave found hiding a similar slider cut conversion rate -2.9%.
