With all the different jurisdictions around the world and the ease with which visitors from those countries can visit a US-based eCommerce website, it's often difficult for online businesses to know what regulations to adhere to. Since GDPR started in the EU, eCommerce businesses have been adding cookie consent↗ to their websites to comply with the regulations. If your website is receiving visitors and processing orders for customers in cookie consent jurisdictions, you'll need to take a look at your compliance status.
Does My eCommerce Website Need Cookie Consent?
Yes. Even though US-based businesses don't need to implement cookie consent under US law in most states, the EU and some other jurisdictions require it from websites that are visited by their citizens. Implementing cookie consent is therefore encouraged for websites based in the US. Unless the website blocks access for customers from jurisdictions with cookie consent laws, they must be compliant.
Local US-Based Cookie Consent Laws for eCommerce Websites
There are some US jurisdictions that are updating their data privacy laws and starting to implement more rigorous requirements. One of these is the California Consumer Privacy Act (CCPA). While CCPA doesn't require informed cookie consent, it does require full disclosure and a method to opt-out of non-essential cookies. Virginia's VCDPA gives consumers the right to access and delete their personal information and requires explicit cookie consent like GDPR. Wisconsin is in the process of passing a data privacy bill. Colorado, Connecticut, and Utah have also had their own data privacy laws enacted recently. There are also provisions specifically for minors in many regulations, so be sure to research those to ensure complete compliance.
Conclusion
All of this may seem like a lot to keep in mind, but there are benefits to privacy laws↗ for both you and the customer, such as avoiding fines↗ and penalties and building customer trust.
How Cookie Consent Affects Your eCommerce Stack
Your eCommerce platform and marketing tools rely heavily on cookies. Shopify, BigCommerce, and most DTC platforms use cookies to track customer behavior, power analytics, and enable personalization. When you implement cookie consent, you're essentially creating rules about which cookies can fire and when.
Google Analytics, Meta Pixel, and other third-party tracking tools require consent before they can collect data in most jurisdictions. This means your conversion tracking, audience segmentation, and retargeting campaigns won't work the same way after implementing consent. You'll need to reconfigure these tools to respect user consent choices.
Your email platform (Klaviyo, Mailchimp, etc.) also depends on cookies for tracking email clicks and checkout behavior. Without proper consent implementation, you risk collecting data that users haven't agreed to share. This affects your ability to build accurate customer segments and measure campaign performance.
The practical step here: before deploying a cookie banner, audit all the tracking tools connected to your storefront. Categorize each one as essential (needed for checkout), functional (improves user experience), or marketing (used for advertising). This categorization will determine which cookies require explicit consent.
What Happens When Customers Reject Non-Essential Cookies
When a visitor to your store rejects non-essential cookies, you lose access to behavioral data that typically feeds your marketing and analytics engines. This is the reality your team needs to prepare for—and it's not as catastrophic as it sounds.
Essential cookies (session cookies, security cookies, checkout cookies) fire regardless of consent status. These keep your store functioning. But the moment someone opts out of marketing cookies, you won't see them in your Meta Pixel audience, your Google Analytics won't track their behavior, and they won't be added to your retargeting lists.
This creates a data gap. Some visitors to your store will have full tracking enabled; others won't. Your analytics reports will show incomplete funnels for opt-out users. Your marketing team won't be able to retarget everyone who visits your product pages.
The upside: the customers who do grant consent are often more valuable. They're explicitly agreeing to be tracked and marketed to, which typically means higher engagement and stronger ROI on your ad spend. You're optimizing for quality over quantity.
For your DTC brand, this means setting realistic expectations with stakeholders about how cookie consent impacts metrics like site traffic attribution, conversion tracking accuracy, and audience size for retargeting campaigns.
Data Subject Access Requests and Your Cookie Data
Once you're compliant with cookie consent laws, especially GDPR and similar regulations, customers gain the right to request what data you've collected about them. This is called a Data Subject Access Request (DSAR).
Your cookie tracking creates a data trail: which pages they visited, what products they viewed, which emails they opened, which ads they clicked. When a customer submits a DSAR, you need to retrieve all of this information and provide it to them within 30 days (under GDPR) or the timeframe specified by your state's law.
If you're using Shopify, you have some built-in DSAR tools, but they don't automatically gather third-party cookie data from Meta, Google, or your email platform. You'll need a process to export data from each tool and compile it into a single response. This sounds tedious, but it's a legal requirement.
The practical implication: start documenting now which cookies and tracking tools you're using, where the data lives, and how long you retain it. Create a DSAR workflow so your team knows who's responsible for gathering data from each source. Without this system in place, you risk missing deadlines and facing regulatory penalties.
Testing Your Cookie Banner Before Launch
A poorly implemented cookie banner creates more compliance problems than no banner at all. If your banner doesn't properly capture consent, doesn't offer a genuine way to reject cookies, or doesn't block non-essential tracking after rejection, regulators will treat it as non-compliant.
Before you deploy a cookie banner on your live store, test it thoroughly. Verify that when a visitor rejects non-essential cookies, Meta Pixel actually stops firing. Check that Google Analytics respects the consent choice. Make sure your email platform doesn't collect behavioral data from opted-out users.
Test across different browsers, devices, and scenarios. Visit your site from a new browser, reject cookies, then check your tracking logs to confirm pixels aren't firing. Do it again from a mobile device. Have team members test the banner's functionality from different countries if your brand ships internationally.
Also test the consent withdrawal flow. Users should be able to change their minds and update their preferences after their initial choice. Make sure this works smoothly and that their new preference is respected immediately.
A properly tested banner protects your brand from the compliance issues that create the most expensive headaches: regulators finding that tracking continues despite users opting out.
