Shopify Collection Optimization: A Practical Guide to +41% Conversion

The hidden “dead weight” in your collections
In most ecommerce stores, collections are the core of conversion. But after months or years of adding products, sales, and seasonal items, many end up as a dumping ground: out-of-stock items, low performers, or duplicates that dilute shopper focus.
This “dead weight” hurts conversion, slows down page load, and confuses users. Internal Skymetrics benchmarks show that strategic cleanup and reordering of collections can deliver up to +41% conversion lift and over $31K in additional monthly revenue.

Diagnosis: What to Measure Before You Optimize
Before touching product order or deleting anything, define which collections deserve attention. Start with three essential KPIs:
1. Conversion Rate (CVR)
Measures the ratio between sessions and orders per collection. Rule of thumb: if a collection has <0.6% CVR and high traffic, there’s friction in layout or product mix.
2. Revenue Share
Percentage of total revenue each collection contributes. Benchmark: your top 5 collections should represent 40–60% of total store revenue.
3. Traffic
Measure both volume and quality (sources, bounce rate, time on page). Combine Shopify and Google Analytics to identify whether visits are intent-driven or casual browsing.
💡 Use Product Analytics in Skymetrics to cross these KPIs in one dashboard and spot underperforming collections instantly.
Reordering and Cleanup Framework
Once you know which collections to prioritize, apply this practical framework to optimize without losing business context.
1. Remove the noise
Hide products out of stock or backordered >30 days.
Remove variants with CTR <1%.
Merge redundant collections (e.g. “Summer Sale” and “Summer Offers”).
2. Order by conversion, not recency
Instead of sorting by “date added,” prioritize products by conversion rate or revenue per session. Test different sorting rules using an A/B order test.
⚙️ In Skymetrics, you can automate conversion-based sorting and performance ranking without manual tags.
3. Improve visual curation
Feature 3–5 hero products at the top.
Keep visual consistency (backgrounds, lighting, tone).
Remove long or unclear titles.
Keep optimal density:
20–40 products per collection
.
4. Create dynamic rules
Set up automated filters:
Show only products with stock >10 units.
Prioritize items with gross margin >X%.
Exclude products with return rate >5%.
5. Iterate every two weeks
Assess the impact every 14 days and compare against your baseline. Continuous optimization saves 4–8 hours per week and keeps collections fresh.
📊 Collection Optimization in Skymetrics automates these review cycles with prebuilt performance and margin rules.
Where to Highlight Your Winning Collections
Once you’ve identified high-performing collections, the next step is to amplify their visibility.
1. Homepage
Add a “Top Collections” or “Most Bought” section. Use dynamic widgets that update based on the last 7 days of performance.
2. Navigation Menu
Feature your top 3 collections in the main or side menu. This increases CTR by up to +20%, according to our benchmarks.
3. Paid Campaigns
Redirect ads to your most profitable collections to boost ROAS by up to +28%. Align Google Ads, Meta Ads, and newsletters with top-performing collections.
4. Newsletter & Remarketing
Include your best-selling collection items in your monthly newsletter. Curated emails see 2.3× higher CTR compared to generic blasts.
Case Study: +41% Conversion After Cleanup
A women’s fashion store with 2,000+ SKUs implemented this framework in just 3 weeks:
Metric | Before | After |
Conversion rate | 1.4% | 1.98% (+41%) |
Monthly revenue | $76,000 | $107,000 (+$31,000) |
Weekly catalog time | 10 h | 2 h (-8 h) |
The improvement came purely from smart catalog curation and conversion-based reordering, not new campaigns.

Frequently Asked Questions
1. How often should I review my collections?
Ideally every two weeks. If your catalog changes quickly, consider weekly checkups using conversion and traffic KPIs.
2. Can I automate conversion-based sorting?
Yes. With tools like Skymetrics Collection Optimization, you can set dynamic sorting rules and run A/B order tests without coding.
3. What’s the difference between catalog curation and cleanup?
Cleanup removes obsolete or poor performers; curation selects the most consistent and representative products for a stronger user experience.
4. How do I measure the impact of reordering?
Compare before-and-after metrics: conversion rate, revenue share, and time on page. Ideally, run a sorting A/B test.
