Unlock more conversions with Extended ID and Shopify Pixel Sync

Nearly 98% of a brand’s website traffic is anonymous. And for marketers, it’s getting harder to identify and engage these anonymous visitors. Browsers like Safari are tightening cookie restrictions, limiting the time you can track user data to as little as 7 days.

What does this mean for you? Missed opportunities. Without knowing what products people are browsing, what they’ve added to their cart or what they abandoned, you can’t engage them effectively. You lose out on the chance to nudge them towards conversion, leaving revenue on the table.

Various mechanisms have emerged to help brands work around these restrictions. Unfortunately, many of these approaches violate data privacy principles by tracking users without their knowledge or consent. For example, cross-site tracking monitors users across different domains without their explicit consent. Another practice is to use third-party identity graphs to resolve device data like IP addresses, browser, and OS version into “highly deliverable email addresses”. These methods are problematic because they rely on data collected without user permission, undermining trust and privacy.

A better way to capture data

Klaviyo offers a smarter and more ethical approach with Extended ID and Shopify pixel sync. These tools are designed to help brands track and identify shoppers in a way that respects user privacy and builds trust. By focusing on first-party data and consent-based tracking, Klaviyo empowers marketers to engage shoppers using previously lost data from anonymous browsing, all while maintaining trust and integrity.

With Extended ID and Shopify pixel sync, brands see on average a 5-10% increase in captured events, turning more anonymous activity into actionable insights. This additional data powers high-performing flows such as abandoned cart flows, which drive the highest revenue per recipient (RPR) and deliver exceptional conversion rates. By accurately identifying users and triggering more of these high-performing flows, brands convert a higher percentage of site visitors, recovering previously lost revenue and improving overall marketing efficiency.

Turn anonymous visits into revenue with Extended ID

Klaviyo Extended ID, now generally available, changes the way you can engage with anonymous shoppers by extending cookie tracking from 7 days to a full year. This longer tracking window helps you identify returning users, making it possible to trigger Klaviyo flows and send personalized messages based on the products they’ve viewed or added to their cart.

Previously, if a shopper visited your site and you captured their email or phone number, once their cookie expired, on a return visit you still couldn’t identify who they were. As a result, if they abandoned their cart, you had no way to re-engage or follow up effectively.

Now when a shopper returns to your site, even if their Klaviyo cookie has expired, Extended ID checks for first-party cookies and does a lookup in our first-party identity graph. If there’s a match, Klaviyo will refresh the Klaviyo cookie, associating their activity against their existing profile. This seamless process ensures that the shopper’s behavior is continuously linked to their identity, so you don’t lose valuable data and can trigger relevant automations based on their actions.

Klaviyo Extended ID works by leveraging a first-party identity graph to map unique, long-lasting identifiers to your Klaviyo profiles. Out-of-the-box, Extended ID supports Shopify’s shopify_y cookie, so if you already use Shopify with Klaviyo, enabling Extended ID is as simple as a few clicks. For added flexibility, you can integrate custom first-party identifiers– or even supply your own tracking or analytics cookie to the identity graph.

This first-party approach is future-proofed in that it is resilient to changes in third-party cookie policies. Klaviyo is working hard to expand out-of-the-box support for additional identifiers, so you can get started quickly with ease.

Capture checkout data with enhanced Shopify pixel sync

While Klaviyo Extended ID focuses on extending cookie lifetime for identifying anonymous users, pixel tracking offers another powerful approach. Pixels are small, invisible images embedded into your website that track user behavior.

Shopify uses pixels to track shopper activity, including anonymous user behavior. When Klaviyo onsite tracking for Shopify and anonymous backfill is enabled, once a user identifies themselves such as through a form fill, Klaviyo creates a user profile and connects all past actions to their Klaviyo profile, allowing you to re-engage them with personalized messages based on their browsing behavior.

We’re introducing enhancements to Shopify pixel sync, starting with the updated Added to Cart event, now available. In the near future, we also plan to add support for the Checkout Contact Info Submitted and Checkout Completed events. These new checkout events will enable you to trigger flows immediately after a customer enters their contact details on the checkout page, even if they bounce before completing a multi-step checkout. In addition to supporting Shopify pixel, we also have plans to enhance our integrations with other commerce platforms with similar functionality in the future.
