When Google first announced the deprecation of third-party cookies in Chrome, it quickly became the talk of the town.<\/p>\n
The industry press coined a new, ominous word: \u201ccookiepocalypse\u201d. Every other webinar or conference was about this topic \u2013 even though, at that point, the consequences were unclear.<\/p>\n
Then, Google postponed these changes; not once, but twice. Partly due to feedback they received from the industry around their Privacy Sandbox solutions, partly due to the scrutiny from antitrust authorities (especially in Europe).<\/p>\n
Speculations started that Google would just keep on delaying the deprecation, and that the fearsome \u201ccookiepocalypse\u201d would, in fact, never materialize.<\/p>\n
Some marketers got complacent. Some were distracted by newer trends, such as Generative AI. Cookieless advertising was no longer considered a hot topic.<\/p>\n
Was this wishful thinking? Speaking at DMEXCO in October 2023<\/a>, Anthony Chavez (VP of Product Management, Privacy Sandbox at Google) gave a clear message: marketers need to get ready for this change, because it\u2019s happening \u2013 beginning in January 2024, when third-party cookies will be phased out for 1% of Chrome users<\/a>.<\/p>\n Yet, there is still a lot of confusion on how to prepare for cookieless advertising. Let\u2019s take a deeper look at how the most common use cases will be impacted.<\/p>\n Download our Free Resource \u2013 The Future of Digital Marketing trends report<\/strong><\/p>\n Download our future of digital marketing report to benchmark your marketing across the 7 pillars of digital marketing and 400+ marketers.<\/p>\n Access the The Future of Digital Marketing trends report<\/a><\/p>\n <\/div>\n <\/div><\/span><\/p>\n Retargeting means showing a customized ad to users who have visited a specific page or taken a certain action on your website. This is typically a high-performing advertising tactic.<\/p>\n With cookieless advertising, new privacy-friendly tracking techniques will be required to enable retargeting. The main difference is that you will need to implement different solutions for different media platforms \u2013 and their approach may vary significantly.<\/p>\n Targeting a lookalike audience means addressing a segment that displays similar interests and behaviours to those of your own website visitors or email subscribers (first-party data).<\/p>\n Like for retargeting, Meta will continue to allow targeting of your website visitors\u2019 lookalikes, providing you have implemented server-side tracking (Meta CAPI).<\/p>\n Everywhere else, lookalike audiences will increasingly rely on hashed email addresses, which makes it even more important to convince users to log-in on your website or subscribe to a newsletter.<\/p>\n Having said that, universal identifiers, such us UID 2.0, generally use a mixture of deterministic data (such as hashed email addresses) and probabilistic data (such as browser version, device type, time zone\u2026) to improve match rate.<\/p>\n If you use DV360 \u2013 Google\u2019s DSP \u2013 another tool available to you is Google PAIR (Publisher Advertiser Identity Reconciliation). Unlike universal identifiers, PAIR\u2019s encryption keys will be unique to each individual advertiser-publisher relationship. This means that data exchanged between a publisher and an advertiser is only used within that business arrangement.<\/p>\n Leveraging your own first-party data through retargeting and lookalike audiences is the best way to future-proof your advertising strategy in a cookieless world. However, for most advertisers, first-party data doesn\u2019t have sufficient scale to be the only targeting technique they rely upon.<\/p>\n Today, third-party data providers and data management platforms (DMPs) use cookies to track users across partnering websites. Advertisers use this data to create detailed user profiles, understanding their interests, behaviours, and demographics. Programmatic advertising platforms use these profiles to target specific audience segment.<\/p>\n These techniques are being disrupted by the demise of third-party cookies and will soon no longer be available. If you are still spending marketing budget on third-party audiences, it\u2019s time to test different cookieless alternatives from the list below and prepare to reinvest your advertising dollars.<\/p>\n This project was originally known as FLoC (Federated Learning of Cohorts) and had its fair share of controversy. With the Topics API, Google has moved away from the initial concept of clustering people with similar interests.<\/p>\n Instead, the Topics API labels each participating website with a topic from a pre-defined list (currently there are 469, which means they are fairly broad). Every week, it then assigns one new topic to each user, based on their most frequently browsed ones. Participating sites can then use three topics from users\u2019 recent browsing history to serve targeted ads.<\/p>\n All the data will live on the user\u2019s browser, to maximize privacy and data security. Sites can opt out of being assigned to a topic, and users will be able to review which topics are assigned to them \u2013 or opt out of Topics completely. Sensitive topics around race, sexual orientation, religion, etc. will not be included in the list.<\/p>\n This refers to two companies sharing their first-party data with each other, through a partnership or collaboration.\u00a0<\/span><\/p>\n An example of this could be a Grocery e-commerce website partnering with a fitness app, cross-referencing their shoppers\u2019 database with the app\u2019s active users. This may allow the retailer to advertise targeted offers to a new audience segment of Fitness Enthusiasts, based on app users\u2019 shopping behaviours.<\/span><\/p>\n Social media platforms and retailers have a wealth of first-party data that they can leverage to segment and target users. This will make their ecosystems even more attractive in a world of cookieless advertising.<\/p>\n Retail media is already seeing explosive growth; however, many advertisers see it mainly as a bottom-funnel media channel. If that\u2019s the case in your company, it may be time to also test top-of-funnel campaigns.<\/p>\n For many years, programmatic advertising promised advertisers to find their target audience anywhere, using behavioural targeting. With the impending deprecation of third-party cookies, displaying ads next to related content is having a major resurgence.<\/p>\n There are many benefits. Firstly, the context where your ads appear is proven to have an impact on their effectiveness. Secondly, contextual advertising feels a lot less creepy to privacy-conscious users.<\/p>\n Download our Free Resource \u2013 The Future of Digital Marketing trends report<\/strong><\/p>\n Download our future of digital marketing report to benchmark your marketing across the 7 pillars of digital marketing and 400+ marketers.<\/p>\n Access the The Future of Digital Marketing trends report<\/a><\/p>\n <\/div>\n <\/div><\/span><\/p>\n Controlling the number of times each user sees an ad is key to limit media wastage. At this stage, cross-site frequency capping is probably the topic related to cookieless advertising with fewer clear answers.<\/p>\n Universal identifiers, like those mentioned earlier, may provide cross-site frequency capping. This will likely be limited to logged-in users \u2013 and scale will depend on publisher adoption.<\/p>\n There are a couple of emerging tech solutions that is worth keeping an eye on:<\/p>\n The deprecation of third-party cookies will deal another blow to multi-touch attribution models (MTA), already impacted by previous privacy updates, like iOS 14. Cookies are also one of the reasons why web analytics have changed. Whilst the topic is too broad to cover in a comprehensive manner in this article, here are a few concepts you need to be aware of.<\/p>\n Google Analytics 4 has been designed to adapt to a future without third-party cookies. Several metrics that were available in previous versions are no longer included, while others require additional configuration. It also includes machine-learning modelling to help fill some of the data gaps.<\/p>\n Google DDA is a machine-learning model that takes into consideration a wide range of data points to determine which touchpoints are most likely to drive conversions. It then attributes conversion credit based on all these factors, offering an alternative to last-click. The big watch-out: it only analyzes interactions with Google touchpoints (Search, YouTube, Display, Discovery etc).<\/p>\n Many advertisers have already turned to Marketing Mix Modelling (MMM), or econometrics. These are statistical models that don\u2019t rely on any tracking or personal data.<\/p>\n MMM is not new \u2013 Consumer Goods giants who rely heavily on TV and other \u201ctraditional media\u201d have been using these for ages \u2013 however a broader interest in this technique has led to an increase in the number of vendors. Some of these have developed sophisticated tech solutions, which make MMM more affordable and almost real-time.<\/p>\n The answer will vary depending on your business model, first and second-party data availability, and current media mix.<\/p>\n However, there are a few steps that can be recommended to almost every advertiser who hasn\u2019t already taken them.<\/p>\n Download our Free Resource \u2013 The Future of Digital Marketing trends report<\/strong><\/p>\n Download our future of digital marketing report to benchmark your marketing across the 7 pillars of digital marketing and 400+ marketers.<\/p>\n Access the The Future of Digital Marketing trends report<\/a><\/p>\n <\/div>\n <\/div><\/span><\/p>\n![\"Cookieless](\"https:\/\/www.smartinsights.com\/wp-content\/uploads\/2024\/01\/Cookieless-Advertising-third-party-cookies-deprecation-timeline.png\")
