Cookie Policies for Ecommerce: What You Need to Know

What Are Cookies and Why Does Your Store Use Them?

Cookies are small text files stored on a visitor's device when they browse your website. They serve several purposes on an ecommerce store: keeping items in a shopping cart, remembering login sessions, tracking site analytics, and powering ad retargeting.

If you run a Shopify, WooCommerce, or BigCommerce store, you are almost certainly using cookies. Even a basic store uses session cookies for the cart and checkout process. If you have Google Analytics, Facebook Pixel, or any marketing tools installed, you are using additional tracking cookies.

Do You Need a Cookie Policy?

If any of the following apply to you, the answer is yes:

• You have visitors from the EU (GDPR and ePrivacy Directive require cookie consent and disclosure)
• You have visitors from the UK (UK GDPR and PECR regulations)
• You use Google Analytics, Facebook Pixel, TikTok Pixel, or similar tracking tools
• You run retargeting ads
• You use Shopify, which sets its own cookies for cart functionality and analytics

In practice, nearly every ecommerce store needs a cookie policy. Even if your primary market is the U.S., you likely have some international visitors, and it is good practice to be transparent about your use of cookies.

Types of Cookies to Disclose

Essential Cookies

These are necessary for your site to function. Shopping cart cookies, login session cookies, and security cookies fall into this category. They do not require consent under most regulations because the site cannot work without them.

Performance and Analytics Cookies

These track how visitors use your site. Google Analytics is the most common example. They collect anonymized data about page views, time on site, bounce rate, and user flow. Under GDPR, these typically require consent.

Marketing and Advertising Cookies

These are used for retargeting and ad tracking. Facebook Pixel, Google Ads, TikTok Pixel, and similar tools place cookies to track conversions and serve targeted ads. These always require consent under GDPR.

Functionality Cookies

These remember user preferences like language, currency, or recently viewed products. They improve the user experience but are not strictly necessary for the site to function.

What to Include in Your Cookie Policy

• What cookies are. A brief, plain-language explanation for visitors who are not technical.
• What cookies your site uses. List each category (essential, analytics, marketing, functionality) with examples of specific cookies.
• Third-party cookies. Name the third-party services that set cookies on your site (Google Analytics, Facebook, Shopify, etc.).
• How to manage cookies. Explain how visitors can disable or delete cookies in their browser settings. Include instructions or links for Chrome, Firefox, Safari, and Edge.
• Consent. Explain how consent is obtained (cookie banner) and how visitors can withdraw consent.
• Updates. Note that the cookie policy may be updated as you add or remove tools.
• Contact information. Provide an email or link for cookie-related questions.

Cookie Consent Banners

A cookie policy alone is not enough if you serve EU visitors. You also need a cookie consent banner that appears when someone first visits your site. The banner should:

• Inform visitors that you use cookies
• Let them accept or reject non-essential cookies
• Link to your full cookie policy
• Not pre-check optional cookie categories

Several Shopify apps and third-party tools can handle cookie consent banners. The important thing is that your banner works correctly and actually blocks non-essential cookies until consent is given.
