Is Retargeting Dead? Cookieless Alternatives for Advertisers (2026)

Retargeting is not dead, but its dominance is over. Criteo's retargeting fell to ~40% of its business, and high-intent attention is moving into cookieless AI assistants where AI-referred shoppers convert ~50% higher. Here is why context-first advertising is the successor and how to run it.

Is Retargeting Dead? The Honest Answer

Retargeting, meaning showing someone ads for the product they browsed but did not buy, still works and still runs at scale. So no, it is not literally dead. But the honest answer is that its position as the default engine of “performance media” is finished. For over a decade, the cookie made it possible to follow a specific person across the web and re-serve them ads, and that capability defined how digital advertising was bought. That capability is eroding, its results are diluting, and better-performing alternatives have arrived. Retargeting is becoming one tactic among many rather than the foundation of the whole system.

The clearest evidence comes from Criteo, the company most synonymous with retargeting. By its own disclosure, retargeting fell from the majority of its business to roughly 40% as privacy changes compressed the addressable pool, and its full-year 2025 revenue slipped about 1% to $1.9 billion. When the pioneer of a category is actively diversifying away from it, the category’s peak is behind it. For the broader picture of what this means for the ad-tech middlemen, see why legacy ad buyers are becoming obsolete.

What Actually Eroded Retargeting’s Dominance

Three forces compressed retargeting. First, privacy: Apple’s App Tracking Transparency and Intelligent Tracking Prevention in Safari, then years of uncertainty over Chrome’s third-party cookies, shrank the pool of trackable users and made cross-site profiles less reliable. Second, performance without full tracking degrades sharply. Industry tests of the cookieless Privacy Sandbox found CPMs dropping about 33% and publishers projected to lose large shares of revenue, which tells you how much of retargeting’s value was tied to the identifier itself rather than to the creative or the offer. Third, and most fundamental, retargeting optimizes for the wrong thing: it reaches people based on past behavior, often in low-intent moments, long after the decision has moved on.

That last point is the real story. Retargeting was always a proxy: “this person looked at running shoes yesterday, so show them running shoes today.” But intent is perishable. The person may have already bought, lost interest, or moved to a different need. Chasing yesterday’s behavior is inherently less effective than meeting today’s intent, which is exactly what context-first advertising does. The frequency-capping horror stories (being followed by the same sneaker ad for three weeks after you already bought the sneakers) are not a bug in execution, they are the built-in failure mode of targeting the past.

In 2025, Google reversed course and decided to keep third-party cookies in Chrome, giving retargeting a reprieve. It would be a mistake to read that as a return to the old normal. The reprieve keeps a declining tactic on life support; it does not reverse the underlying shift in where high-intent attention lives. Consumers are moving their research and buying decisions into AI assistants, and those surfaces are cookieless by design. You cannot retarget a ChatGPT conversation. The medium capturing the most valuable moments simply does not run on the identifier retargeting depends on.

So even in the best case for retargeting, where cookies persist in one browser, the growth is happening somewhere retargeting cannot follow. Budgets follow attention, and attention is moving to first-party and context-matched advertising. The reprieve buys time; it does not change the destination. Smart teams are using the extra runway not to double down on cookies, but to build the two things that survive every privacy change: first-party relationships and conversation-matched creative.

Where the Money Is Actually Going: First-Party Data and Retail Media

The first big destination for post-cookie budgets is first-party data, and the clearest example is retail media. Retailers like Amazon and Walmart know, deterministically, what their logged-in customers actually bought, which means no cookie syncing and no probabilistic modeling. That data survives every privacy change because it is first-party, and it enables closed-loop measurement: a brand can see whether the person who saw the ad actually put the product in the cart, sometimes down to the SKU. That is why US retail media ad spending is forecast to reach roughly $71 billion in 2026, up about 17.8% year over year, growing faster than both search and social.

But first-party retail media has a ceiling that context-first advertising does not: concentration and reach. Amazon and Walmart are projected to capture about 89% of all incremental retail media spending in 2026, so most brands are competing for a thin slice on someone else’s platform, and retail media only reaches people who are already shopping on that specific retailer. AI assistants reach people earlier, at the moment they are deciding what to buy at all, and they do it without requiring the advertiser to own the customer relationship. The two are complementary: first-party data for the customers you already have, context-first AI advertising for the high-intent strangers deciding right now.

Context Is the New Performance Media

The replacement for cookie-based targeting is not a worse version of it, it is a better-performing model. In controlled tests, contextual ads delivered 29% higher ad recall and lifted brand awareness to 43% (versus 18% for cookie-based), and contextual commerce media drove 2x the incremental ROAS of behaviorally targeted programmatic. Contextual placements have been measured driving 2.1x more attention, and a Seedtag and Columbia neuroscience study found 3.5x higher neural engagement for neuro-contextual ads. The pattern is consistent: matching the ad to the moment beats matching it to a stored profile.

AI assistants take this to its logical extreme. The “context” is no longer a web page’s topic, it is a live, high-intent conversation in which a person is actively reasoning toward a purchase. That is why AI-referred shoppers convert at roughly 50% higher rates than organic search (Shopify Q1 2026; Adobe measured 54% in May 2026), carry higher order values, and start over half their sessions already on a product page. Context-first advertising is not a defensive move against privacy rules, it is where the best performance now lives.

How Advertising Works Without Cookies Inside AI

Inside ChatGPT and the other assistants, there is no cookie and no cross-site profile. Instead, you provide context hints, which are structured descriptions of the topics, intents, and moments where your ad belongs, and the platform’s language model matches your ad to conversations that fit. Targeting becomes semantic rather than identity-based: you are describing the situation you want to be relevant in, and the model places you when a real conversation matches. OpenAI has been explicit that ads are matched to the conversation context, kept clearly labeled as sponsored, and that user conversations stay private from advertisers, which is the privacy story retargeting could never tell.

This flips the workflow. Instead of building audiences from tracking data, you build precise context hints and, critically, creative that matches each conversation. Because the auction is relevance-weighted, the advertiser with tightly matched creative for each intent wins the placement, which means the bottleneck moves from data to creative. The businesses that thrive in cookieless advertising are the ones that can produce many on-brand, conversation-specific ads quickly. See targeting without keywords for the mechanics.

The Cookieless Playbook: What to Do Now

You do not have to wait for the cookie question to fully settle to future-proof your acquisition. This is the practical sequence most teams should run:

  1. Stop treating cookies as the foundation. Keep retargeting as a small retention tactic, not the core of your performance plan. Rebalance budget toward first-party and context-first channels.
  2. Build first-party relationships. Grow owned data (email, loyalty, logged-in accounts) and use retail media where your customers already shop, so you have deterministic signal that survives privacy changes.
  3. Claim the high-intent moment. Stand up context-first campaigns inside AI assistants, where buyers are actively deciding, using precise context hints per intent cluster.
  4. Move your investment from data to creative. In a cookieless, relevance-weighted world, conversation-matched creative is the lever. Generate many on-brand variants, one per intent.
  5. Measure with first-party signals. Use platform conversions APIs and your own analytics rather than third-party tracking to close the loop.

Frequently Asked Questions

Is retargeting dead in 2026?
Not literally, since cookie-based retargeting still works and runs at scale, but its era of dominance is over. At Criteo, the company that pioneered retargeting, it fell from the majority of the business to about 40% as privacy changes shrank the addressable pool, and full-year 2025 revenue slipped about 1%. Retargeting is becoming one tactic among many rather than the foundation of performance media, because better-performing, privacy-safe alternatives (first-party retail media and context-first AI advertising) have arrived, and the highest-intent moments are moving into cookieless AI assistants.
If Google kept third-party cookies, why is retargeting still declining?
Google keeping cookies in Chrome is a reprieve, not a reversal. It keeps a declining tactic on life support but does not change where high-intent attention is moving. Consumers are shifting research and buying into AI assistants, which are cookieless by design, so you cannot retarget a ChatGPT conversation. Budgets follow attention, and attention is moving to first-party and context-matched advertising. Smart teams use the extra runway to build first-party relationships and conversation-matched creative rather than doubling down on cookies.
What is replacing retargeting after the cookie?
Two cookieless successors are absorbing the budget. The first is first-party data environments like retail media, where US spend is forecast to reach roughly $71 billion in 2026, growing faster than search and social, because retailers have deterministic purchase data and closed-loop measurement. The second, and higher-intent, is context-first advertising inside AI assistants, which reaches people earlier, at the moment they are deciding what to buy, without requiring the advertiser to own the customer relationship. They are complementary: first-party data for existing customers, context-first AI for high-intent strangers.
What is context-first advertising and why does it perform better?
Context-first advertising matches ads to the moment and meaning of what someone is doing right now, rather than to a stored profile of past behavior. It performs better because intent beats identity: contextual ads delivered 29% higher ad recall and 2x the incremental ROAS of behavioral programmatic in controlled tests, and contextual placements drove 2.1x more attention. Inside AI assistants the context is a live, high-intent conversation, which is why AI-referred shoppers convert roughly 50% higher than organic search.
How does advertising work without cookies inside ChatGPT?
There is no cookie or cross-site profile inside AI assistants. Instead you provide context hints, which are structured descriptions of the topics, intents, and moments where your ad belongs, and the platform’s language model matches your ad to conversations that fit. Targeting becomes semantic rather than identity-based, and OpenAI keeps conversations private from advertisers. The workflow shifts from building audiences out of tracking data to building precise context hints plus creative that matches each conversation, and because the auction is relevance-weighted, the advertiser with tightly matched creative wins.
Is retail media the same as context-first AI advertising?
No. Retail media runs on a retailer’s first-party purchase data and reaches people already shopping on that retailer, with excellent closed-loop measurement but concentrated reach, since Amazon and Walmart are projected to capture about 89% of incremental retail media spend in 2026. Context-first AI advertising reaches people earlier, in the moment they are deciding what to buy at all, across any category, and does not require the advertiser to own the customer relationship. Most brands should run both.
What should performance marketers do about the cookie transition now?
Run a five-step playbook: stop treating cookies as the foundation and keep retargeting as a small retention tactic; build first-party relationships through owned data and retail media; claim the high-intent moment with context-first campaigns inside AI assistants; move investment from audience data to conversation-matched creative; and measure with first-party signals and conversions APIs rather than third-party tracking.
