Cookieless MarketingLess tracking, better marketing

What 'cookieless' actually means#

The phrase is slightly misleading. Websites still use cookies. What is changing is the reliability of third-party cookies: those set by a domain other than the one you are visiting, typically by ad tech companies, which allowed a person to be recognised as they moved across many sites. They powered much of retargeting, cross-site audience building, frequency capping and view-through attribution.

First-party cookies, set by the site you are on, remain widely used for logins, carts and on-site analytics, though browsers increasingly limit their lifespan in some situations. So 'cookieless' really means 'without dependable cross-site tracking'. That is a meaningful change, and it is already the reality for a large share of web traffic.

Why it is happening#

Three forces are at work. Browsers: Safari and Firefox block third-party cookies by default, and Apple's mobile platform requires apps to ask permission before tracking users across other companies' apps. Chrome's plans have changed more than once, so check the current position rather than relying on any article, this one included. Regulation: laws such as the EU's GDPR and India's DPDP Act put consent and purpose at the centre of processing personal data. Expectations: people increasingly notice, and dislike, being followed around the web.

Whatever any single browser decides, the direction is clear. Planning marketing on the assumption that you can track individuals across the open web is planning on a shrinking foundation.

Do not plan for the return of tracking. Plan for marketing that does not need it.

What breaks, and what does not#

Large platforms with logged-in users (search engines, social networks, marketplaces, streaming services) are less affected inside their own environments, because they recognise users through accounts rather than third-party cookies. This concentrates targeting power in those walled gardens, which is worth remembering when weighing their claims about their own effectiveness.

Expect reported numbers to fall even when real results do not.

The strategy: five shifts#

1. 01Build first-party relationships. Give people reasons to sign up, log in, join a loyalty programme or opt in to WhatsApp updates. See our guide to first-party data.
2. 02Use context and intent. Place ads next to relevant content and against relevant searches. Context was the original targeting method and remains effective.
3. 03Feed platforms better first-party signals. Send consented conversion data from your systems through platform conversion APIs and offline conversion tracking, so their algorithms optimise on real outcomes.
4. 04Measure without individuals. Use incrementality testing and marketing mix modelling, which work on aggregates and controlled comparisons.
5. 05Invest in brand. When precise targeting is harder, being known and remembered does more of the work. Brand search and direct traffic become more valuable signals.

Contextual targeting, done properly#

Contextual targeting is sometimes dismissed as a step backwards. It is better seen as a return to first principles: reach people when the subject is on their mind. A home-loan provider advertising beside property articles, or a running shoe brand beside marathon training content, needs no profile of the reader to be relevant.

Modern contextual tools classify pages by meaning rather than keywords, which reduces crude mismatches, and they allow brand-safety rules to be applied at the same time. The craft lies in mapping the moments that precede purchase in your category, then finding the content and search queries where those moments happen. Creative matters more too: an ad that fits its context earns attention that a generic one does not.

A note for mobile-first markets#

In markets such as India, where much of the journey happens on mobile apps, messaging and marketplaces rather than the open web, the cookie debate is partly beside the point. Many consumers move from a social app to WhatsApp to a marketplace or a UPI payment without ever passing through a cookie-tracked browser journey. Measurement here has always relied on first-party data, platform-native signals and asking customers directly. The lessons travel well: own the relationship, capture source at the point of conversation, and test what your channels add.

Measurement without cross-site tracking#

The loss of individual paths hurts multi-touch attribution most. Teams that relied on it should not try to rebuild it with fingerprinting or other workarounds, which carry legal and reputational risk and are actively countered by browsers. Instead, accept a layered approach.

A low-tech technique deserves more use than it gets: asking. A single 'How did you hear about us?' question at checkout or enquiry, with sensible options, captures channels no tracker can see, including podcasts, word of mouth and offline media. It is imperfect, because memory is imperfect, but it is a useful counterweight to click-based data.

Alternative identifiers and privacy technologies#

Various industry identifiers based on hashed emails or other signals, data clean rooms that let two parties match data without sharing raw records, and browser-proposed privacy APIs have all been offered as replacements for third-party cookies. Some have real uses, particularly clean rooms for large advertisers and publishers. Their availability and adoption change, sometimes abruptly, so evaluate each against current documentation and legal advice rather than building a strategy around any one of them.

Where to start#

The organisations that adapt best treat the change as a prompt to do marketing well: earn relationships, say relevant things in relevant places, build a brand people seek out, and measure with methods that respect privacy. Those were good ideas before cookies were restricted. They are necessary now.
