The digital world is in constant evolution, and the recent wave of cookie deprecation policies from tech giants has sent ripples through the marketing world. The Privacy Sandbox initiative, led by Google, is committed to phasing out support for third-party cookies on Chrome by Q3 2024. 

These policies signify a seismic shift in the way brands must now collect and leverage user data, posing both challenges and opportunities for marketers, product owners, and businesses who want to deliver tailored experiences even for anonymous visitors. Looking forward, marketers need to prioritize cookieless personalization

In this blog, we take a look inside the cookieless era to provide marketers with insights and actionable strategies to succeed moving forward when personalization via cookies is no longer an option.

3 steps to prepare for the cookie phase-out

To prepare for a future without cross-site user tracking, it is crucial for brands to adopt a proactive approach. We’ve broken this down into three key steps and strategies that marketers and product owners should start prioritizing to craft a marketing strategy that is aligned with the latest privacy regulations while preserving the essence of personalized marketing.

1. Audit your third-party cookie usage

Begin by identifying the third-party cookies your website relies on to kickstart conversations with your developers. Inspect your website code in incognito mode to spot instances of cookies being set and sent on requests. For an in-depth look at cookie-related issues, head to the DevTools Issues Tab in the Chrome DevTools application panel. Under the Storage section, check out the ‘Cookies’ section to browse through the ones stored for your site and accessed during the page load. You can also preview which ones will be potentially affected after the phase-out with a definitive prompt, “Cookie sent in cross-site context will be blocked in future Chrome versions.”

This audit will serve as a foundation to build your data-led marketing strategy for the privacy-centric future. Marketers as well as product owners should use this as a baseline to start aligning with technical teams.

2. Future-proof your road to personalization with zero-party data

Zero-party data has been called ‘the new oil’ by Forbes because of its huge potential for new kinds of cookieless personalization. The stringent new regulations and announcements don’t apply to zero-party data, making it a promising data-driven route marketers can take to shape their personalization strategy

But how do you go about collecting and using zero-party data?

3. Turn to the right signals that fuel cookieless personalization

Pivot your strategy to leverage meaningful and contextual data points that do not rely on cookies to understand behavior and intent. 

Define condition groups that do not rely on third-party data to trigger campaigns, for example:

  • Rely on your website architecture to drive personalization. For example, you can trigger campaigns based on Page Type or URL.
  • Bank on your product catalog details like Product Name, Category, or Price to deliver offers, announcements, and messages on your website.
  • Leverage cookieless data points like Device Type, Browser, or Operator information to tailor experiences for your website visitors.
  • Make the most of in-session information to trigger experiences in real-time for your users. Deliver experiences based on the Number of Items in the Cart or upon Exit Intent.

Innovative personalization: Embracing change for a privacy-first internet

Despite the sunsetting of third-party cookies, one thing remains unchanged: Customer expectations for personalized experiences. The demand for tailored interactions persists, which means personalization is here to stay. 

However, without traditional tracking methods, it’s essential for brands to explore cookieless personalization solutions that resonate throughout the customer lifecycle, ensuring maximum lifetime value
