Organic product traffic

What's Included

Traffic without conversion is just expensive vanity. I treat your store as a system — every product page, collection, and checkout step optimized to turn browsers into buyers and one-time buyers into repeat revenue.

Product & Collection SEO

Optimized product schema, collection pages, and category architecture that rank and convert.

Conversion Rate Optimization

Data-driven testing of product pages, cart, and checkout to remove friction and lift AOV.

Merchandising Strategy

Smart upsells, bundles, and cross-sells that increase average order value without discounting.

Site Speed & UX

Lightning-fast storefronts — because every 100ms of delay costs conversions.

Lifecycle & Retention

Email/SMS flows and post-purchase journeys that turn first orders into lifetime value.

Analytics & Attribution

Clean tracking so you know which channels and pages actually drive profit.

What You Get

  • Store-wide CRO audit with prioritized test backlog
  • Product and collection SEO optimization
  • Merchandising and upsell strategy
  • Checkout and cart optimization
  • Lifecycle email/SMS flow setup

Frequently Asked Questions

Which platforms do you work with?

Shopify is my primary focus, but the growth principles apply to WooCommerce, BigCommerce, and custom Next.js commerce builds too.

Is this SEO or conversion?

Both — they compound. More qualified traffic plus a higher conversion rate multiplies revenue rather than just adding to it.

Can you help with abandoned carts?

Yes. Cart and checkout optimization plus automated recovery flows are part of the lifecycle work.
