Cookie Consent for E-Commerce: A Guide for Shopify, WooCommerce & Magento

E-Commerce Has More Cookies Than You Think

The typical e-commerce website runs 30 to 60 cookies and tracking scripts. Payment processors, abandoned cart recovery, product recommendations, retargeting pixels, affiliate tracking, live chat, reviews widgets — each adds cookies and data collection that require consent.

E-commerce sites face higher scrutiny because they process sensitive data: purchase history, payment details, and browsing behaviour that reveals personal interests and financial capacity.

Platform-Specific Challenges

Shopify

Shopify's ecosystem includes hundreds of apps, each potentially adding cookies. Common tracking on Shopify stores:

• Shopify Analytics (built-in)
• Facebook/Meta Pixel and Conversions API
• Google Analytics 4 and Google Ads conversion tracking
• Klaviyo, Mailchimp, or Omnisend for email marketing
• Product review apps (Judge.me, Loox, Yotpo)
• Upsell and recommendation apps

The challenge: Many Shopify apps inject scripts that you can't easily control. Theme code often loads scripts in ways that are hard to conditionally block.

LegalBanner solution: Our script works at the browser level, intercepting and blocking scripts regardless of how they're loaded. Add one script tag to your theme.liquid and all third-party scripts are governed by consent.

WooCommerce (WordPress)

WooCommerce sites inherit WordPress's plugin ecosystem. Each plugin can add its own cookies:

• WooCommerce session and cart cookies
• Payment gateway cookies (Stripe, PayPal)
• SEO plugins (Yoast) may add analytics
• Marketing plugins (WooCommerce Google Ads, Facebook for WooCommerce)
• Caching plugins that set their own cookies

LegalBanner solution: Add the script tag to your header.php or use the "Insert Headers and Footers" plugin. LegalBanner scans and detects all plugin-added cookies automatically.

Magento

Magento (Adobe Commerce) is typically used by larger stores with more complex tracking setups. Key considerations:

• Magento's own customer tracking cookies
• Adobe Analytics integration
• Complex tag management with Google Tag Manager
• Third-party extensions for marketing automation

Essential vs Non-Essential: E-Commerce Edge Cases

E-commerce creates some classification questions:

• Shopping cart cookies — Necessary (the store can't function without them)
• Payment processor cookies — Necessary (required to complete a purchase)
• Abandoned cart recovery — Marketing (tracks user behaviour for remarketing purposes)
• Product recommendation engine — Functional or Marketing, depending on whether it uses personal data
• Conversion tracking pixels — Marketing (sent to third-party ad platforms)
• Customer review solicitation — Marketing (involves sending user data to a third-party review platform)

Impact on Conversion Rates

E-commerce store owners worry that cookie consent will hurt conversions. The data shows otherwise:

• Well-designed consent banners have 70–85% acceptance rates
• Google Consent Mode v2 provides modelled conversions for non-consenting users
• Trust signals (visible privacy controls) actually increase purchase confidence
• Non-compliance risks are far more costly than any conversion dip

LegalBanner is designed to maximise consent rates through clean design and clear language, while never using dark patterns or manipulative UI.
