Overview

A CRO toolkit you install, not a project you scope

Conversion Rate Optimizer gives you a library of ready-made storefront blocks, sections and embeds that you add and customize in the theme editor — no code or developer needed. Choose from upsells, countdown timers, live visitor counts, stock indicators, shipping bars, star ratings, testimonials, FAQ accordions, comparison tables and trust badges. A built-in analytics dashboard reports impressions, clicks and attributed revenue.

Most conversion rate optimization advice ends with "so build that." This app skips that step. Every tactic you'd normally brief to a developer — urgency, scarcity, social proof, risk reversal, order-value nudges — is already a block waiting in the theme editor sidebar. You drag it in, write your copy, pick your colors, and publish.

Because each block reports its own impressions, clicks and attributed revenue, you can run your storefront like a test program instead of a guess: keep what earns, remove what only adds noise. Our Shopify CRO guide walks through which leaks to plug first, and raising average order value covers the upsell side in more depth.

Raise order value on product, cart and checkout

Trust sections

Answer objections before they cost you the sale

Trust sections: testimonials, FAQ, comparison tables and logo sliders. Handle the “is this legit and is it right for me?” question on the page, while the shopper is still there to convince.

  • Testimonials and star ratings as full-width sections
  • FAQ accordions that answer without a page change
  • Comparison tables that position you against the alternative

Drop a block where you want it and edit copy, colors, timing and rules in the sidebar. Preview it before you publish.

No. Every block is a theme app block, section or embed. You add it in the Shopify theme editor, drag it where you want it, and customize the copy, colors and behavior in the sidebar. There's no Liquid to edit and no code to paste.

There are 20+ blocks covering upsells and cross-sells, countdown timers, live visitor counts, stock indicators, free-shipping progress bars, star ratings, testimonials, FAQ accordions, comparison tables, logo sliders and trust badges.

On product, cart and checkout pages — so you can raise average order value at each of the three points where a shopper is already committed to buying.
