The use of third-party cookies has been in place for quite some time, which has so far helped advertisers gain insight into the audience's online activities. But in the past few years, with so many changes happening in the digital world, there has been a swift decline in the use of these cookies. More than 50% of the audience is rejecting cookie tracking.
With the growing privacy concern and regulation and increasing rejection of cookie tracing, it has become quite challenging for advertisers to target the right audiences for their campaigns.
Why Third-Party Cookies Are Not Working?
With the use of third-party cookie insights, advertisers are able to track user activities across multiple channels and websites and analyse their online behaviour without any consent. This has raised many privacy concerns and has become quite an alarming issue for the online audiences.
To counteract the unethical user tracking and data misuse, the government has introduced strict regulations, GDPR, and CCPA. Primary sites like Safari and Firefox have also withdrawn their support for third-party cookies as online users are demanding more transparency and control over their unnecessary data tracking.
This has forced advertisers to look for other solutions to target their potential audiences. This has also allowed advertisers to rebuild trust and a strong relationship with their customers by maintaining transparency and abiding by all the privacy regulations.
What Can Replace Third-Party Cookies?
As the traditional way of targeting and retargeting audiences is disrupted, advertisers need to think out of the box, and there is no single solution or replacement for it. As advertisers can no longer rely on passive data collected through cross-site tracking, they need to shift from identity-based tracking to privacy-compliant signals and relationships.
Advertisers need to focus on groups rather than individuals, context, and data that users have given consent to be used.
There is no one rule to be followed; different businesses will have different solutions and strategies as per their business goal and audience requirements.
Here, we will discuss a few strategies advertisers can opt for if their business goal is to gain customers.
Contextual Advertising
This is best for raising brand awareness and reaching out to new customers. For this, marketers need to buy an audience segment or ad space from a publisher. This way, you can reach out to new customers and also retain existing ones.
This type of targeting might not be precise, as they are not concerned about user identity, but are totally privacy-safe. Contextual targeting, when powered with AI, has the ability to understand the relevance and meaning of the campaign to target the right audiences at the right time without cross-tracking users' online activities.
First-Party Data
It is the data collected with user consent. First-party data is the user-related information and insights that are gathered directly from the users with their full consent. It can be from your website, app, or CRM system, where you can ask for user data, and if the user is willing to share, he/she can share the details, which can be later used for targeting and retargeting.
This helps marketers to make personalised ad campaigns and proper customer segmentation by sending personalized messages, emails, and exclusive offers to their respective customers.

Consent-Based Identifiers
Consent-based identifiers are those that opt in either by signing up, logging in, or subscribing to a program. These users agree to the policies and then provide information that can be later used for marketing purposes, as per their consent.
Even though they don't reach as many users as third-party cookies did. They provide excellent targeting in trusted environments that have a high probability of sales.
Google Privacy Sandbox
This one is restricted to Chrome users only and is suitable for broad-reach campaigns within the Google ecosystem. Google launched the Privacy Sandbox, which consists of several new APIs and features added to the Chrome browser, to help advertisers target audiences correctly.
These APIs are made to enable targeting through on-device processing rather than sending raw user data to external ad platforms. They operate locally on the user's device, within the browser.
It's crucial to remember that, despite their privacy-preserving methodology, solutions linked to a user's browser often encounter difficulties for reach optimisation, frequency management, and cross-device attribution. Campaign efficiency is impacted by these browser-based models' inability to reliably differentiate between real users and devices.
Targeting Strategies For Cookieless Advertising
Follow these effective strategies to swiftly move towards cookieless advertising:
- Audit on how you are currently using third-party cookies. Track the usage of third-party cookies in all of your platforms, measurement systems, and advertising campaigns.
- Increase the amount of first-party data collected with consent. Employ value exchange strategies to gather first-party data in ways that are both user-friendly and compliant.
- You can improve your first-party data gathering by providing people with clear value, such as exclusive offers, early access to sales, discounts, and promotions.
- Map the dependencies between your audience targeting and measurement. Recognise which components of your marketing plan are completely dependent on data from third parties and those that can be replaced with other solutions.
- Use tools that enable you to activate and collaborate on first-party data. Use privacy-first solutions like data clean rooms to work together on your first-party data with publishers, merchants, or independent data partners.
- Build KPIs and get ready for new measurement methodologies. Recognise that outdated attribution models might no longer be effective. Start experimenting with clean room-based reporting, modelled conversions, or incrementality.
- Test and analyse performance. To monitor performance, make adjustments, and get better, run A/B tests on various targeting options.
Are You Ready For Cookieless Future Marketing?
Cookieless Advertising is not the end, but rather a much-needed shift towards a more intelligent and privacy-focused strategy. While third-party cookies are eliminated, performance, targeting, and personalisation are evolving in a much better way rather than going away.
If you become among the early adopters, it will be easier to obtain the trust of consumers and gain a long-term advantage. Although the shift may appear disruptive, it benefits marketers who prioritise long-term value, relevance, and transparency over quick, untrustworthy tracking tricks.
