Key Takeaways

• There is no one universal ID yet, and there is none that would come into the future. UID2, RampID and ID5 may be meaningful but have limited adoption by buyers as a result, implementing any of them does not make participants addressable by all advertisers.
• Third-party cookies were not really removed from Chrome. Google has reversed its deprecation plans, yet in fact, they have already been blocked by both Safari and Firefox, and thus you’re likely to operate in a cookieless environment anyway.
• Authenticated users are at the core of every identification solution. The majority of alternative IDs utilize hashed emails and, consequently, can operate only with those visitors who have provided their email.
• Identified users cost substantially more than anonymous ones. Network information shows that publishers earn more than 50% from logged-in identified visitors compared to unidentified users on similar pages.
• Contextual signals provide traffic information unavailable to identity. A regular visitor will unlikely log in, and therefore the page-level context is what makes inventory saleable at good prices.
• Most of the technical effort should be carried out by your advertising partner and not you. Running multiple ID integrations requires a lot of work from advertising operations while the job of the publisher is to gather all the data necessary for such operations.

For years the industry told publishers to wait: a single replacement for the third-party cookie was coming, and once it arrived you would plug it in and carry on. That replacement never arrived. No universal ID reached the coverage third-party cookies once had, and in 2026 nobody credible expects one to.

What replaced the waiting is orchestration: running several identity signals at once, backed by your own first-party data, so that buyers can recognise your audience in whatever environment they are bidding from. Adapex’s 2026 outlook puts it plainly: the hope that a single identity solution would emerge has faded, and publishers who diversify their identity inputs are seeing more stable revenue as cookie-based demand declines. This guide translates that into something a smaller publisher can actually act on.

Publisher Identity Solutions in 2026: Why No Single ID Won

The universal ID market fragmented instead of consolidating. Unified ID 2.0, backed by The Trade Desk, and RampID from LiveRamp have the strongest demand-side adoption in the United States. ID5 carries a larger footprint in Europe. Prebid’s SharedID serves a different purpose, giving unauthenticated traffic a usable signal. Each has different levels of DSP support, which is the detail that matters most to publishers.

The practical consequence is that integrating a single identity solution does not make you addressable to every buyer. Getting reasonable coverage across your demand sources requires several integrations running in parallel, each with its own consent and data-sharing requirements. It is worth understanding what these IDs actually are before evaluating them: most, including Unified ID 2.0’s publisher implementation, are built on hashed email addresses. They identify a user only when that user has given you an email and consented to its use. No email, no ID.

The Cookie Situation Is More Confusing Than It Looks

A point of confusion worth clearing up: Google reversed its plan to remove third-party cookies from Chrome, so they still exist there. That reversal did not restore the wider picture. Safari and Firefox have blocked third-party cookies for years, app tracking limits continue to bite, and privacy regulation keeps tightening. A significant share of your traffic is already cookieless, which is why Safari inventory has historically monetised at a discount. Our explainer on how web cookies work for publishers covers the distinction between first-party and third-party cookies, which is the part most publishers conflate.

The Publisher Identity Solutions Checklist for 2026

Collect email addresses deliberately, not incidentally

Every hashed-email-based ID depends on having an email in the first place, which makes newsletter signups and account creation identity infrastructure rather than just audience-building. The revenue case is direct: network data reported by ppc.land shows publishers earning more than 50 percent additional revenue from logged-in, identified visitors compared with unidentified users on otherwise comparable traffic.

Get consent handling right before scaling collection

An email you cannot legally pass into an identity graph is worth nothing for monetisation. Your consent management platform needs to capture permission for the specific uses each ID requires, and that consent has to travel with the signal. This is the step small publishers most often skip, and it invalidates the work that follows.

Run multiple IDs rather than betting on one

Because buyer adoption differs by ID and by region, coverage comes from running several. In practice that means authenticated IDs for logged-in users plus a fallback signal for everyone else. This is ad operations work rather than editorial work, and it is the part a managed partner should be handling: Newor Media’s managed header bidding maintains these integrations across demand partners so publishers are not individually negotiating and maintaining each one.

Treat contextual signals as the majority case

Realistically, most of your visitors will never log in or hand over an email. For that traffic, page-level context is the signal that keeps it sellable: topic, content category, sentiment, and placement quality. Clean site structure, accurate categorisation, and consistent metadata do real monetisation work here, and they cost nothing beyond editorial discipline.

Build audience segments from behaviour you already have

You do not need individual-level tracking to create value. Behavioural grouping, segmenting readers by the content categories they consume, recency, and engagement depth, produces sellable audience signals without exposing unique user IDs. Our comparison of zero-party versus first-party data covers which categories of data are worth collecting and how they differ in value to buyers.

What This Looks Like If You Have No Ad Ops Team

Split the work honestly. The publisher’s half is collecting emails, handling consent properly, keeping content categorisation clean, and growing the share of visitors who are identified. The technical half, maintaining ID integrations, passing signals correctly into the bidstream, and keeping up as buyer adoption shifts, belongs with your monetisation partner or the SSPs in your stack. If you are unsure which half your current setup covers, that is a reasonable question to put to your ad network directly: ask which identity solutions your inventory currently passes and what share of your traffic carries an ID at all.

Frequently Asked Questions

What is identity orchestration for publishers?

Identity orchestration is the practice of utilizing various identity signals simultaneously instead of putting faith on a single signal. Essentially, this concept involves the usage of authenticated IDs based on hashed email addresses, an alternate identity signal for visitors without authentication, customized first-party audience segments, and contextual signals regarding traffic with no identification. The approach emerged because no single universal ID provided the coverage achieved by third-party cookies at the time of their existence, which makes it necessary to rely on a combination of solutions.

• Each identity approach can be supported by different DSPs meaning that a number of integrations can achieve the desired coverage.
• Contextual signals are used for most of the users, since the majority of users do not login ever or provide their email address.

Are third-party cookies actually gone in 2026?

This is not related to Chrome. Google reversed its decision about not using third-party cookies, hence they are still operational there. Meanwhile, the decline has proceeded: Safari and Firefox have blocked cookies long ago, mobile apps have limited tracking and there are more and more laws protecting privacy. Consequently, a considerable portion of traffic is now already cookieless, although there was no formal stopping of their usage, and that is why publisher inventory in Safari has monetized worse than in Chrome.

• Make a comparison between RPMs in Chrome and Safari so that you’ll find out how much has your cookieless traffic already cost you.
• First-party cookies that are created on your domain are not influenced by any of these transitions.

Which universal ID should a small publisher implement?

The framing seems to be off slightly because the answer is hardly ever one. UID2 and RampID have the highest buyer adoption in the USA, while ID5 has a more significant footprint in Europe, and there is a backup identifier for unverified visitors. For a smaller publisher, the more relevant question is what IDs are being utilized and supported by your advertising partners since implementing and maintaining any identity solution is essentially ad operations and not something that needs to be managed internally on a case-by-case basis.

• Find out from your network which identity solutions are being passed in the bidstream with regards to your inventory.
• Also, try and get an idea about the share of your traffic that has any identification since that is the figure that counts here.

Do I need logged-in users to benefit from identity solutions?

For authenticated layers, the answer is a yes, as most alternative IDs rely on hashed emails and cannot track a user without one. Because of this, newsletters and accounts are more of an identification system that generates revenues instead of merely attracting audiences. The gap in revenue is huge as the network data indicates that the amount of revenue generated by identified users is 50% more in comparison with unidentified ones.

• Even small identified audience percentages significantly increase the average RPM.
• Anonymous traffic can still be monetized via contextual signals and fallback identifiers.

Is contextual targeting a real alternative or a fallback?

Regardless of whether or not customers authenticate, contextual signals help to sell this inventory. The general idea is that contextual signals become the principal source of selling inventory, rather than being something to fall back on. Elements such as subject matter, content category and sentiment become very relevant for companies willing to buy inventory, especially for companies that prefer peace of mind over risk when considering their campaigns. Clean categorization and reliable metadata can be used here.

• Correct categorization is not expensive, apart from the use of the right editorial technique.
• Contextual and identity-based systems are used in combination rather than competing for the same impressions.
