8、s are more privacy friendly?Theres evidence to suggest that,contrary to the assumption that hyper-targeting is the route to success,the technique can inhibit brand success,and that some leading post-cookie solutions are less secure than they may seem.In this Deep Dive,we will make the case for why o

14、ple.Right?The answer isnt no,but it isnt a resounding yes either.Stripping advertisers arsenals of third-party cookie-based solutions removes one intrusive targeting method.However,some of the cookieless solutions that have emerged or been heavily promoted in the run up to deprecation dont necessari

20、sociation withData clean rooms not quite a tidy solutionData clean rooms(DCRs)have been pitched as the go-to alternative to cookie-based targeting that allow companies to gain greater audience insight without compromising on privacy.While current data clean rooms differ in certain respects(something
21、 which the IAB are trying to change),all of them allow different sources of data to be aggregated and matched.Uploaded information is anonymised and kept within the confines of the clean room it is not shared with participating companies.At face value,using a DCR sounds like an effective way for adv
22、ertisers to reach more people in a way that protects consumer information.However,the claim that data clean rooms are inherently privacy-preserving requires a closer look.These platforms may not grant participants user-level data,but that doesnt mean that participants cant find ways to access it.At
23、present,there are no barriers to a publisher employing“ad observation”to link the personal data match keys of their own audiences segments to those stored in a data clean room,for example.The fact that such a practice is theoretically possible suggests that the privacy of DCRs may be overstated.Part
24、icipants should also take note of the lack of clarity regarding how clean rooms actually comply with privacy regulations,with approaches differing between providers:Snowflake place the onus of“applying the appropriate security and privacy rules,such as removing customers that havent consented to the
25、 use of their data”onto clean room participants;Habu,meanwhile,who say they“enforce the highest security and privacy standards”in their clean room,provide no clear information of whether and to what extent users are responsible for data security.52%45%41%39%DCR that we manageand controlDCR owned and

28、sguided,and companies could risk falling foul of regulation if they continue to perceive them as such.Until there is greater clarity around who is liable for what,participants should be wary about just how clean DCRs are.Scale is also a challenge.Match rates remain low,which is not a surprise when p
29、ublishers only have data on 3-10%of their visitors.The IAB State of Data 2023 report sums it up bluntly:“Sub-par match rates threaten the overall efficacy of DCRs.”Yet perhaps the central flaw of DCRs,and ID solutions generally,is that,at their core,they are still highly dependent on identity.This l

32、eWire Ltd.2023 |In association withHyper-targeting overhyped?The purpose of audience data,cookie-based or ID-based,is to enhance the capacity to target specific audiences.In digital,the goal has been to achieve what legacy media like TV could never realise:one-to-one communication.Digital audience d
33、ata has sought to be deterministic since the beginning the goal being what we will refer to as hyper-targeting.The notion that narrowing down targeting to segments of people who may be more interested in a particular product or service will achieve better results has captivated our industry for year
34、s,and been central to the development of much of our technology.However,it may not be true.From a strictly logical perspective,reaching out to a smaller pool of people involves avoiding a large portion,automatically restricting the number of potential conversions.Furthermore,the conventional belief
35、that targeting a smaller group is preferable because they possess qualities that make them more inclined to engage is not always accurate.This was the case for P&G,who found that sales of Febreeze air freshener stalled when they targeted Facebook ads exclusively to people with families and pets,but
36、improved after the campaign was opened up to anyone over the age of 18.This discovery led the consumer goods giant to conclude that they“targeted too much”and to roll back on hyper-targeting via Facebook.Assuming that a small portion of the population will drive the majority of a brands sales is mis
37、guided at best.How many times can you expect the same consumer to buy a certain product,especially big ticket items,like mattresses or cars?In the words of Byron Sharp,“Sales growth wont come from relentlessly targeting a particular segment of a brands buyers”.In the long term,limiting outreach to t
38、hose who are already familiar with a brand risks shutting it away from wider public consciousness,causing it to“lose its place in culture”.Hyper-targeting isnt as effective as many commonly believe,and a big reason for this is because personalisation is challenging.Effective personalisation depends
39、on having access to high quality data,something which has long been difficult and will continue to be impacted by new data laws.Moreover,the growing fragmentation of audience attention makes targeting more difficult and more expensive,and consumers increased awareness and concern over how companies
40、use their data has made some less receptive to targeted advertising.These factors the privacy issues posed by alternative IDs and clean rooms,and the limitations of hyper-targeting lead us to one simple conclusion:that probabilistic targeting is the way forward.The conventional belief that targeting

44、OT MEAN COMPROMISING PERFORMANCEWe believe that theres a case to be made for returning to mass reach,or one-to-many advertising based on probabilistic data.In our view,this is the only audience model that can be truly private,as it is the only model that avoids using personal data.Better still,there
45、s evidence that it can be more effective than hyper-targeted approaches.Probabilistic targeting makes“best-guess inferences using data that is not traditionally considered personally identifying,”for example,contextual or IP addresses mapped to neighbourhoods.This means that not only does probabilis
46、tic data afford more privacy to web users,but also that its future-proof:as weve seen from the flurry of new privacy laws being introduced across the world in recent years,and the increased scrutiny of Big Tech companies handling of user data by authorities like the European Union,regulation is only
47、 going to get tighter.Navigating new legislation will become trickier,and the penalties for failing to comply will be severe.Therefore,investing in probabilistic-based solutions now will prevent the need to give up deterministic ones to meet future regulatory changes.A probabilistic approach could e
48、ven address the privacy issues that currently impact data clean rooms.The challenge at the very core of the clean room model is that it is anchored by personally identifiable information.As Ampersand chief privacy officer and general counsel Noga Rosenthal notes,“How does this solve the identity iss

54、 outside of walled gardens are already hindering advertisers capacity to accurately target their campaigns,and will only cause hyper-targeting to become more expensive.Uniting probabilistic approaches and mass reach offers advertisers greater potential to get their message across to consumers.Return
55、ing to mass targeting(as traditionally seen in TV,radio,and print)will involve relinquishing the impulse to place identity at the centre of targeting.However,it is possible,and,if done effectively,can be very rewarding.Two such approaches that have already seen adoption are contextual targeting and
56、using offline demographic data.Contextual echoes the traditional model of mass media for instance,a furniture brand might bid for inventory within the ad break of a home renovation TV show,or an activewear brand might buy space within the sports pages of a newspaper.While contextual has previously b
57、een dismissed as primitive,new developments have made the approach more accurate,and it has been found to increase purchase intent by 63%.As it doesnt rely on user data,contextual advertising is now considered“a solid segmentation method thats inherently anonymous”.Evolutions in modelling and method
58、ology coupled with the strength of digital delivery mean that leveraging offline demographic data is more fruitful than during the heyday of broadcast TV:moving on from panel-based modelling,firms can now use aggregated location information such as or IP addresses matched to neighbourhoods to segmen
59、t the population and deliver more targeted ads.A perfect example is an anonymised household targeting campaign for BMW.This approach is intrinsically anonymous,and can combine reach and precision for more effective messaging.None of this is to suggest that returning to a mass-reach approach is easy,
60、but if the trade-off between reach and precision is right,the advertiser wins.Embracing probabilistic data and combining it with mass reach can help advertisers avoid mounting privacy concerns and achieve better results than they may have previously believed.DigisegContextual1P party data3P audience

65、ir thoughts with us.What have been the biggest challenges youve faced since the shift away from third-party cookies and identifiers?PZ Its been difficult to build towards a singular consumer view across all touchpoints to manage and enhance the consumer journey and accurately measure our impact acro
66、ss key media touchpoints.Measurement is always an issue and having the right tech solution in place hasnt been the easiest to resolve,but we are moving towards platforms that enable us to still be able to generate enough accurate insights from our key consumers in order to inform future planning.ST
67、Its been a long time,and we are still looking for a single/unified solution for post third-party cookie deprecation.Publishers,tech vendors,advertisers,and agencies have been evaluating and testing new IDs,but the most significant challenge is the disconnection between parties,and we are facing:scal
68、ing issues performance issues comparison issues;and after years,we can still say that the world of IDs is unknown.Also,commercialising essential targeting components is not ideal and indicates an extra fee in the chain.BK The transition away from third-party cookies and identifiers has exacerbated t

74、probabilistic targeting will play in the post-cookie world?PZ Deterministic is probably the better space to play in and as more brands and publishers focus on growing their first-party data,we will see the scale issues we currently have no longer be a significant problem.Plus,ad tech should essentia
75、lly be better at helping increase match rates in the future as the technology improves.Probabilistic still plays a part because it at least allows us to make assumptions based on various data points,in order to create persistent identifiers.ST ID graphs and the growing need for richer deterministic
76、data on a single user can bring a new way of digital targeting and personalisation,but in contrast,we will always have visitors without common data touch points and data sets for composing ID graphs.Therefore,we need to combine different tactics and strategies to push relevant ads or messages the co
77、nsumers way.On the other hand,using ID graphs and segments,marketers can use probabilistic approaches:such as behavioural data overlay to the seed audiences,and creating lookalike models or setting independent conditions in their DMPs or CDPs for users who dont have the crucial data for ID graphs.We
78、 are in the evolutionary phase of the next generation of digital advertisements.Most publishers(without login and subscription)rely heavily on probabilistic data and are trying to find their way towards ID graphs.However,we have more years ahead to create a solid structure across digital media globa

83、eting?PZ For broad marketing,I agree that contextual is and always has been a viable solution.Even when it comes to personalisation of messaging,you can still be relevant by diving into the assumed interests of the audience,utilising semantics aligning with the content on the page.This is not the on
84、ly solution however and there is a lot being done to grow our own first-party data,publisher cohorts based on logged in data and clean rooms where we can still gather insight with publishers and retailers,create audiences using partner data to activate against,or create lookalikes to drive better ef
85、fective marketing.ST Contextual targeting is just one of the forms of independent solutions from cookie and ID,but not the only one,and it has its limitations.We know many other targeting options:viewability,performance-based(ad unit level),postcode-level targeting,just to name a few.We have to use
86、and consider these technologies as complementary solutions and combine their capabilities to cover and maximise our reach with relevant information in a privacy-compliant and user-first way.Eventually,the control of the data will shift back to its owners,who are the end users and customers,and this
87、will be the right outcome.BK Contextual targeting has been used for some time and does have its advantages.However,third-party targeting was far more effective.Advertisers and publishers can still collect rich data from their audiences that goes beyond context,allowing for more targeted advertising
88、and better results.In cookie-and ID-free targeting,partnerships with publishers who understand their audience,creators who are honest and transparent about their audience,cross-functional marketing partner programs and affiliate partnerships with allowed cookies for business purposes(not ID Free)wil
