Where this started

After 8 years building Shopify features for fashion, wellness, and lifestyle brands doing serious volume, I noticed something consistent. The features that actually moved conversions weren't complicated — sticky add-to-cart buttons, smarter image galleries, well-timed upsell flows, cart drawers that didn't leak. Implemented cleanly and in the right place, they reliably improved add-to-cart rates and reduced abandonment. The difference was knowing which ones to prioritise, and how to build them properly.

Most store owners can see what top brands are doing but can't replicate it without hiring a developer or subscribing to yet another app. Collective Theme started as my answer to that — production-tested conversion snippets, stripped down and documented so any store owner could install them in minutes.


What Collective Theme is now

It's grown beyond snippets. Collective Theme is a suite of tools for Shopify store owners who want to understand their market, improve their store, and make smarter decisions — without needing an agency or a developer on call.

The snippet library is still at the core: every piece of code has been run on a live store, measured against a baseline, and packaged with a plain-English install guide. But alongside that, there are now free tools that give you the kind of market intelligence that used to require a paid analyst.


What's in the toolkit

Conversion Snippets
Paid

Drop-in Liquid + JS features for your Shopify theme — sticky add-to-cart, cart drawers, upsell flows, image galleries, and more. Every snippet is production-tested, owner-documented, and yours permanently once purchased.

Price Comparison Tool
Free

Search across 5.6M+ Shopify storefronts to see how your product prices compare to the market. Includes a price distribution chart, an anchor price feature, and a side-by-side comparison panel — useful before you set or adjust pricing.

Chrome Extension
Free

Inspect any Shopify store from your browser. Export product data as JSON or CSV, bulk-download images, and trigger price comparisons directly from a product page — no API key or account needed.

Shopify SEO Guides
Free

Practical long-form guides on Shopify SEO and organic search — written from eight years of working on stores with real traffic, not recycled generic advice. Topics range from technical foundations to AI Overviews and content strategy.

Free Store Audit
Free

Share your store URL and I'll look at your product pages, trust signals, and checkout flow, then tell you exactly where the conversion leaks are and which features would have the biggest impact. No strings attached.


What you can trust about this

Snippets are tested before they ship

Nothing goes into the library until it has been run on a live store and measured. If it didn't move a metric, it doesn't make the cut.

Guides are written for store owners, not developers

Install guides assume zero coding knowledge. Step-by-step, with screenshots where it matters — most installs take under 10 minutes.

You own the code outright

Once you purchase, the code lives in your theme, not on an app server. It keeps working whether or not Collective Theme exists.

Free tools have no catch

The comparison tool, the Chrome extension, and the SEO guides are genuinely free. No account required, no trial period, no upsell gate.

Support if something doesn't work

If a snippet has an issue in your specific theme, reach out. I'd rather fix it than leave you stuck.
