What happens to your pipeline when the small bits of code that quietly follow your buyers around the web stop working the way they used to? It sounds dramatic, but that is exactly what is happening as browsers limit third-party cookies and privacy rules tighten. Chrome has already started restricting third-party cookies for a slice of users and keeps shifting how this will work at scale, which keeps marketers guessing.
At the same time, Google has stepped back from a full, hard deprecation of third-party cookies and is moving toward more user choice and privacy controls, not a clean cut. So you live in a strange in-between moment: not fully cookieless, not fully cookie-based either.
The real question is not only about technology. It is about you, your buyers, and whether your agency partners can still deliver personalized, relevant experiences using identity and consented data instead of old tracking tricks.
Yes, some B2B digital agencies are already adapting to the cookieless economy and identity-driven personalization
Many teams in a B2B Digital Marketing Agency world have stopped waiting for a final deadline. They are already acting as if third-party cookies will become weaker every quarter. In fact, a lot of marketing leaders now treat first-party and so-called zero-party data as the main fuel for targeting and personalization, not as a side project.
You can see the shift in three visible ways:
- Agencies push clients to collect more first-party data, like newsletter signups, event registrations, trial accounts, and gated content downloads. This data is captured directly on owned properties with consent.
- They experiment with identity-driven tools such as customer data platforms, hashed identifiers, and data clean rooms that let brands match audiences without exposing raw personal data. They redesign measurement so it does not depend only on last-click cookie trails but uses modeled attribution, uplift tests, and CRM-based revenue tracking.
On the surface, this might look like a downgrade compared to the old retargeting era. In practice, some agencies are already seeing the opposite: cleaner data, less noisy audiences, and more trust from buyers who know why they are being asked to share information.
Oddly, the cookieless push makes some decision cycles sharper, not weaker. When data comes straight from your own channels, you can tie it more clearly to opportunities, pipeline, and closed deals.
No, many B2B digital agencies are not fully ready for the cookieless economy and identity-driven personalization yet
Now the uncomfortable part. While the leaders are moving fast, a large group of agencies is still stuck halfway. Surveys of marketers show an interesting split: most feel confident about a cookieless future, yet only a minority have actually implemented proper solutions; a big share is still just researching or testing.
You may notice some warning signs:
- Your media plans still talk more about third-party audiences and retargeting lists than about first-party segments.
- Your reporting deck is packed with cookie-based metrics but thin on CRM, account, or identity-level insight.
- Privacy, consent, and data governance feel like “legal topics” rather than part of campaign design.
In those cases, personalization risks becoming weaker over time, even if impressions and clicks still look fine for a while. The data under your targeting is slowly eroding while dashboards pretend everything is normal.
So yes, some agencies are “doing cookieless” mainly in presentations, not yet in production.
Readiness for the cookieless economy and identity-driven personalization depends on each B2B digital agency and its clients
Here is the tricky part: it is both fair and unfair to say agencies are not ready. The truth sits in the messy middle.
If you work with an enterprise-focused agency that serves regulated industries, there is a good chance they already take identity and privacy seriously. These clients usually:
- Have stronger CRMs and marketing automation in place.
- Run account-based programs where known users and accounts matter more than anonymous reach.
- Care a lot about compliance with GDPR, CCPA, and sector rules, so they invest in consent and governance.
On the other side, if your business is smaller, or your main play is quick-turn performance campaigns, your agency might still rely heavily on cookie-based retargeting and lookalike audiences. It is not always laziness; sometimes you simply do not yet have enough first-party signals to build rich identity graphs.
So readiness is not a single yes or no. It depends on:
- Data maturity of your company.
- Tech stack on both your side and the agency side.
- Willingness to trade short-term convenience for long-term resilience.
You might even find that your agency is strong in one area and weak in another. For example, they may be advanced in consent management but still early in data clean room adoption. That contradiction is normal at this stage.
B2B digital agencies can become ready for the cookieless economy and identity-driven personalization by changing how they use data
If you are wondering what “good” looks like, think in terms of a new contract between you, your buyers, and your partners. Agencies that want to be truly ready usually follow a few practical moves.
First, they design for consented data. That means clearer forms, value-driven offers, and honest messaging about why you ask for data and how you use it. Done well, this does not just tick a legal box; it can improve lead quality because people who say yes usually care.
Second, they build identity-centric architectures:
- A customer data platform or similar hub to unify data from web, email, product, and CRM.
- Strong identity resolution rules to connect multiple signals to the same person or account.
- Safe collaboration options, like data clean rooms, so you can work with publishers or partners without exposing raw personal data.
Third, they retrain teams. Media planners, performance marketers, and content strategists are coached to think in terms of:
- “What do we know directly from our own touchpoints”
- “What has the user clearly agreed to share”
- “How do we personalize based on that, without feeling creepy”
Finally, they test relentlessly. In a space where Google’s plans and browser rules keep changing, nobody has a perfect playbook. What sets strong agencies apart is not certainty; it is the habit of running controlled tests, comparing identity-based flows with legacy ones, and moving budget toward what works.
If you are a client, you can push this forward by asking simple but sharp questions:
- Which parts of our current strategy would break if third-party cookies dropped to zero tomorrow
- How much of our targeting and measurement is already powered by first-party or consented data
- What is our plan for identity-driven personalization over the next 12 to 18 months
The answers will tell you more than any glossy pitch deck.
So, are B2B digital agencies really ready?
In short, some are ahead of the curve, some are behind, and many are learning in real time. The cookieless economy is not a distant future; it is slowly arriving in your dashboards, CPMs, and lead flows right now. Identity-driven personalization is not a buzzword either. It is the only way to keep relevance without breaking trust.
If your agency, and your own team, can treat this shift as an upgrade rather than a threat, you will likely come out stronger. If not, the market will eventually make that choice for you.
