Category Page Design: Best Practices for E-commerce

Category pages are where shopping decisions begin. They’re the bridge between browsing and buying—and poorly designed category pages let potential customers slip away.

This guide covers the essential elements of category pages that convert browsers into buyers.

The Role of Category Pages

Category pages serve multiple critical functions:

Users landing on your site often start with category pages. They’re orienting themselves, understanding your offering, and deciding where to go next.

Product Discovery

For users who don’t know exactly what they want, category pages help them explore options and narrow down choices.

Comparison Facilitation

Many shoppers want to compare multiple products before clicking through. Category pages should make this easy.

SEO Gateway

Category pages often rank for broader keywords (“running shoes,” “coffee makers”) and serve as entry points for organic traffic.

Essential Category Page Elements

1. Clear Category Title and Description

Title:

Descriptive and specific
Matches navigation and user expectations
Keyword-optimized for SEO

Description:

Brief overview of the category
What products users will find
Why your selection is worth browsing
Keep it short—users want to see products

Example: “Women’s Running Shoes (128 products) High-performance running footwear for every distance, from daily trainers to race-day speedsters.”

2. Product Grid/List

Grid view:

Best for visual products (fashion, home goods)
Shows more products per screen
Image-focused comparison

List view:

Better for technical products (electronics, B2B)
Shows more details per product
Easier to scan specifications

Best practice: Default to what works best for your products, but offer users the option to switch.

3. Product Cards

Each product card should include:

Essential:

Product image (clear, consistent)
Product name
Price
Star rating and review count

Valuable additions:

Sale price/discount indication
Quick view button
Color variants preview
Stock status (“In stock” / “Only 3 left”)
“Add to cart” without clicking through

Considerations:

Consistent card dimensions
Hover states with additional info
Mobile-optimized layout

4. Filtering and Sorting

Filters (allow users to narrow by):

Price range
Size
Color
Brand
Rating
Availability
Product-specific attributes

Sorting options:

Best selling / Most popular
Newest
Price: Low to high
Price: High to low
Rating
Alphabetical

UX best practices:

Show applied filters clearly
Easy to remove individual filters
“Clear all filters” option
Show number of results
No page reload (AJAX filtering)

5. Pagination or Infinite Scroll

Pagination:

Clear page numbers
Previous/next navigation
Shows total pages
Better for users who want to track progress

Infinite scroll:

Seamless browsing experience
Higher engagement
Harder to reach footer
Can feel overwhelming with large catalogs

“Load more” button:

Hybrid approach
User-controlled expansion
Good middle ground

Recommendation: Pagination or “Load more” for most stores. Infinite scroll works well for discovery-focused browsing (fashion, inspiration).

6. Results Count

Always show: “Showing 48 of 128 products”

Users want to know:

How many options exist
How many they’re currently viewing
How filtering affects results

Navigation and Breadcrumbs

Show path from home: Home > Women’s > Shoes > Running Shoes

Benefits:

Helps users understand site structure
Easy navigation to parent categories
SEO value (internal links)
Reduces bounce rate

If category has sub-categories, display them prominently:

Running Shoes ├── Road Running ├── Trail Running ├── Track & Field ├── Racing Flats └── View All

Place at top of page or in sidebar.

Back to Top

For long category pages:

Sticky “Back to top” button
Or sticky header with key actions

Mobile Category Pages

More than half of e-commerce traffic is mobile. Mobile category pages need special attention:

Grid Considerations

2 columns is typical for mobile
Larger images for easier visual identification
Card content must be readable

Filter Experience

Full-screen filter modal (not cramped sidebar)
Large touch targets
Clear “Apply” and “Reset” buttons
Show result count before applying

Infinite Scroll Caution

On mobile, infinite scroll can make it impossible to reach footer navigation. Consider “Load more” or pagination.

Sticky Elements

Sticky filter bar at top
Floating “Back to top” button
Easy access to sort options

Performance Optimization

Page Speed

Category pages often have many images, impacting load time:

Lazy load images below the fold
Use optimized image sizes (not full-res)
Limit initial products shown (24-48)
Compress images properly
Use CDN for assets

Skeleton Loading

While content loads, show placeholder skeleton UI. Feels faster than blank screen or spinner.

Caching

Cache category pages for returning visitors
Cache filter combinations if possible
CDN caching for static elements

SEO Considerations

Unique Content

Avoid duplicate content across similar categories:

Unique descriptions per category
Unique title tags and meta descriptions
Canonical tags where appropriate

Internal Linking

Category pages should link to:

Sub-categories
Featured products
Related categories
Buying guides/content

URL Structure

Clean, descriptive URLs:

✅ /womens/shoes/running-shoes
❌ /category.php?id=1234

Conversion Optimization Elements

Show category-level social proof:

“5,000 reviews across this collection”
“Bestseller” badges on top products
“Trending” or “Popular this week” sections

Promotional Messaging

If running promotions:

Banner at top of category
Sale badges on product cards
Clear discount communication

Comparison Features

Help users compare products:

Quick-compare functionality
Hover to see key specs
Side-by-side comparison tool

Common Category Page Mistakes

Too Many Products Per Page

Loading 200 products slows page speed and overwhelms users. 24-48 is typically optimal.

Filters That Don’t Work

Broken filters, slow AJAX, filters that return zero results—all frustrate users. Test thoroughly.

Inconsistent Product Cards

Different image sizes, missing information, varied styling across products looks unprofessional and makes comparison difficult.

No Empty State Handling

When filters return zero results:

Clear message explaining no results
Suggestions to broaden search
Link to related categories
Don’t just show a blank page

Ignoring Mobile

Desktop-focused designs that don’t adapt to mobile lose more than half your potential customers.

Poor Product Titles

Product names that require clicking through to understand aren’t scannable. “SKU-7892” tells users nothing.

Testing Category Page Changes

What to Test

Products per page (24 vs. 48 vs. infinite)
Default sort order
Filter placement (sidebar vs. top)
Product card content (add review count, add quick view)
Grid columns (3 vs. 4 on desktop)
Featured sections placement

Metrics to Track

Primary:

Product page click-through rate
Conversion rate (from category page visitors)

Secondary:

Time on page
Filter usage
Scroll depth
Bounce rate
