Implementation Paths

Shopify Development Shopify Design Shopify CRO

1) Low-Contrast or Hidden Mobile CTAs

Add-to-Cart buttons that blend into page backgrounds or require extensive scrolling on mobile devices destroy conversions.

Use high-contrast primary CTA colors and sticky bottom bars.

2) Uncompressed Studio Images Destroying Speed

Uploading 5MB raw PNG images slows down mobile rendering.

Compress image files to WebP or AVIF format under 150KB per file.

3) Hiding Shipping & Delivery Timeframes

Shoppers want to know when their order will arrive.

Display estimated delivery dates directly near the buy button.

5) Missing Customer Photo & Video Reviews

Static text-only reviews lack authenticity.

Integrate photo and video UGC reviews using apps like Judge.me or Okendo.

Actionable Insights

Replace tiny text links with high-contrast Add-to-Cart buttons.
Add explicit size charts and fit indicators for fashion products.
Compress all store imagery to next-gen WebP formats.
