Political advertising has advanced significantly in recent decades. Historically, campaigns had limited options for where they could advertise, and those channels had limited inventory. Political campaigns primarily relied on radio, print, and linear TV to reach voters, using mass marketing strategies to appeal broadly to unspecified audiences. These mediums had limited targeting capabilities and provided few data insights. However, this has all changed thanks to the rise of technology and changing media consumption habits.
With the advent of the internet and the emergence of various digital channels, political campaigns now have more inventory and options for getting their message out there, including connected TV (CTV) —a subset of advanced TV that has become a predominant channel for digital ad spend. CTV is the fastest-growing medium for political ads, with the upcoming 2024 election expected to see $1.5 billion in CTV marketing ad spend (nearly half of all political digital advertising dollars!). CTV’s share of political ad spending is set to jump from 2.7% in 2020 to 12.8% this year. The Harris campaign is leading the charge, allocating $200 million for digital ads, much of which will go to streaming platforms.
CTV advertising promises to be an effective method for political campaigns trying to reach voters with personalized content in 2024. Let’s look at CTV political ads a little closer and overview the implications for your political campaign.
The growth of CTV in political advertising
CTV has become central to political ad strategies in helping campaigns gain exposure through targeted, personalized ad experiences to specific audience segments based on demographics, behaviors, and interests. With CTV advertising, political campaigns have become more adaptable to changing viewer preferences and can ensure their messages resonate with diverse audiences across digital platforms. This strategy represents a critical opportunity for political campaigns to tap into the growing viewership of streaming and adjust their marketing plans to meet voters where they spend their time.
Although traditional broadcast TV remains at the forefront of political advertising, recent increases in CTV political ad spending in 2024 reflect shifting media consumption preferences toward streaming services. Today, the average American adult spends almost 2 hours per day on CTV devices. It’s worth noting that CTV has the most significant audience share with Millennials, which makes CTV an especially worthy investment for targeting the younger generations whose voting habits aren’t as established yet.
2024 political ad spending
Compared to the previous U.S. presidential election year in 2020, campaigns and interest groups are expected to increase their political ad spending promoting causes and candidates by almost a third in 2024, totaling approximately $12.32 billion, according to Reuters. This is said to encompass all advertising for federal, state, and local politics, including lobbying and election activities.
While traditional media still dominates political ad spending, digital platforms are growing, with 45% of digital ad spending projected to be allocated to CTV for its refined targeting capabilities and increased inventory in this election cycle. For reference, only 19% of digital political ad spend went to CTV in 2020.
While the presidential election tends to garner the most attention among voters, it’s essential to note that political ad spending goes well beyond the big race; over 500 seats are up for election in 2024. Down-ballot races and issues in state and local elections will significantly impact where ad dollars are allocated.

This precise targeting ensures your political ads reach the most receptive audiences and maximizes the impact of your ad spend.
Third-party cookie deprecation and CTV
The phase-out of third-party cookies has created a challenge for political campaigns relying on digital advertising strategies. In the past, political advertisers have used cookies to track a user’s web activity to understand their browsing behaviors across sites and create detailed profiles for targeting purposes. However, due to recent changes in online privacy regulations, third-party cookies are going away.
Political advertisers have recognized the need for innovation and are exploring new avenues for effectively reaching target audiences without third-party cookies. CTV has arisen as a promising solution, as it doesn’t rely on these cookies to paint a picture of audiences and offers an alternative for precise, privacy-compliant targeting and ad spend optimization. CTV publishers tend to know quite a bit about audiences, including their viewing habits, location, preferred CTV devices, and more —and utilizing this information can give your campaign deeper, more accurate data without invading user privacy.
Benefits of CTV over traditional TV advertising for political campaigns
CTV political ads are a great way to familiarize a candidate’s core audiences with their message and engage them with the campaign. Here are some specific ways a political campaign can benefit from CTV in its advertising strategies.
Broadened access to data
Traditional broadcast and cable TV are a means of one-way communication. This means viewers consume broadcasted content without direct interaction or a feedback loop for tracking engagement and behavior data.
CTV solves the limitations of traditional TV by offering access to more data than linear TV using technology and internet connectivity to gather real-time insights. CTV data on audience interactions, preferences, demographics, behaviors, location, income, and more enable precise targeting and tailored messaging for more impactful campaigns. Furthermore, digital infrastructure enables CTV devices to track clicks, ad impressions, and conversions, which marketers can use to understand interests, viewing habits, and audience demographics more effectively. To sum it up, CTV broadens the scope of data available for political campaigns to refine their targeting.
Targeted, personalized ad experiences
With traditional TV advertising, marketers have historically had to rely on mass marketing strategies, broadcasting ads to a general audience and hoping to reach the right demographic segments. This imprecise approach limits a marketer’s control over who sees their ads and wastes time and money.
In contrast, CTV platforms can collect abundant data on viewer behavior, preferences, and demographics, helping advertisers precisely target audiences and reach groups most likely to benefit from the ads. With CTV, advertisers can segment audiences based on gender, age, interests, location, and past viewing behavior. This level of granularity enables them to customize their messages to resonate with specific people and increase the relevance and effectiveness of their political ad campaigns. By delivering ads to the right groups of people at the right time, CTV helps advertisers maximize campaign impact and drive better results.
It’s worth noting that streaming viewership is beginning to change. Although younger generations have engaged the most with CTV, there is research to show that older generations are starting to help fuel its continued growth. Gen X and Baby Boomers have begun to embrace streaming and seek out ad-supported services to ad-free alternatives. These gradual shifts in behavior highlight the importance of understanding streaming generations to reach target audiences effectively.
Real-time ad campaign optimization
While traditional TV relies on fixed ad placements, CTV offers programmatic buying, which refers to buying and selling ad placements on CTV through automated technology. Programmatic CTV advertising is highly data-driven, which gives advertisers flexibility in their messaging strategies, helps them refine their targeting, and deliver relevant ads to the right people at the right time. With real-time analytics, campaigns can monitor ad performance, adapt to changing circumstances, and make data-driven decisions to maximize advertising impact and budget efficiency leading up to the election.
Challenges and considerations for advertisers
Despite how widely beneficial CTV advertising can be for political campaigns, marketers also need to be aware of its limitations.
Navigating ad fraud
Ad fraud is a major problem for unsuspecting advertisers. CTV ad fraud involves fake CTV devices or bots mimicking viewership and cheating marketers into paying for unviewed or non-existent ad placements. According to DoubleVerify’s Global Insights, CTV bot fraud increased nearly 70% in 2022 compared to the previous year, with CTV fraud instances tripling since 2020. In 2023, digital ad fraud cost the marketing industry $84 billion. These ad fraud schemes are rising due to the high CPM of CTV ads, leading to a bigger payout for fraudsters who steal ad dollars.
One of the primary challenges is the need for better technological safeguards to detect and mitigate illegitimate traffic, such as bot activity. Political advertisers often rely on third-party ad fraud and verification technologies to avoid falling victim, but these solutions cannot guarantee complete protection. This usually leaves advertisers unaware of fraudulent activities until they’ve already incurred financial losses.
As political campaigns increasingly embrace CTV political ads, they become bigger targets for fraud and must make protection and measurement central to validating their campaign efficacy in conjunction with robust fraud detection measures. These efforts can help protect the integrity of political ad campaigns, mitigate fraud, and ensure messaging reaches genuine voters.
Ensuring ad effectiveness
Measurement and attribution of CTV political ads can be challenging. CTV offers better insights into audience preferences and behavior than linear TV, but despite the existing measurement tools, CTV is fragmented, involves many platforms, and lacks standardized metrics and attribution models tailored to political campaign goals. These problems make it hard to compare campaign performance, track CTV users across their viewing experience, and ensure ads appear in the right environments.
To fully understand your ad effectiveness, you should ensure accurate tracking mechanisms of audience behaviors with individual ads to assess the impact of CTV campaigns on voter engagement and turnout. This will help you better understand how to achieve campaign objectives, where to focus your efforts, and how to appeal to viewers in future campaigns.
It may also be helpful to understand some of the metrics advertisers currently employ for CTV measurement, including completion rate and return on ad spend (ROAS). Because CTV ads often can’t be skipped, this advertising strategy has a high completion rate, sometimes nearing 90%. ROAS is more focused on what you get in return for your ads, allowing you to track profits per dollar spent on ads. Political marketers can also use metrics like campaign impressions, total reach, view-through rate, and cost per completed view to understand how their ads are performing.
Ethical considerations related to transparency and misinformation
Political advertisers are responsible for upholding transparency and accuracy in their messaging to build trust with voters. Given how polarized the current political climate is, misinformation could make or break a political campaign. Whether intentional or unintentional, spreading misinformation through CTV can undermine the democratic process and erode public confidence in political institutions. Political marketers must do their best to prioritize ethical conduct, adhere to regulatory guidelines, and ensure their ads convey truthful information to voters.
Looking ahead: CTV in the 2024 elections
The current election cycle promises record-breaking political ad spending in 2024 and will underscore CTV’s role in shaping the future of political communication and engagement. With shifting viewer preferences and the ongoing evolution of digital media consumption habits, political campaigns need to look at CTV as a critical platform for voter engagement so they can allocate resources and shift their strategy to harness its full potential.
Using the targeted capabilities and expansive reach CTV advertising offers, political entities can optimize ad creative for the streaming environment, implement data-driven targeting strategies, and effectively connect with voters across diverse demographics and geographic regions.

Note: While third-party cookies are no longer being phased out, this webinar was recorded in 2023 when cookie deprecation was still a key industry focus. The strategies discussed reflect that time frame and remain relevant for addressing broader signal loss challenges. With major browsers discontinuing support for third-party cookies, marketers must rethink how to identify and engage their audiences. Contextual advertising offers a privacy-safe solution by combining contextual signals with machine learning to deliver highly targeted campaigns. In a Q&A with our experts with eMarketer, Jason Andersen, Senior Director of Strategic Initiatives and Partner Solutions at Experian, and Alex Johnston, Principal Product Manager at Yieldmo, we discuss how contextual advertising addresses signal loss, improves addressability, and delivers better outcomes for marketers. The macro trends impacting marketers How important is it for digital marketers to stay informed about the changes coming to third-party cookies, and what challenges do you see signal loss creating? Jason (Experian): Third-party cookies have already been eliminated from Firefox, Safari, and other browsers, while Chrome has held out. It’s just a matter of time before Chrome eliminates them too. Being proactive now by predicting potential impacts will be essential for maintaining growth when the third-party cookie finally disappears. Alex (Yieldmo): Third-party cookie loss is already a reality. As regulations like the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA) take effect, more than 50% of exchange traffic lacks associated identifiers. This means that marketers have to think differently about how they reach their audiences in an environment with fewer data points available for targeting purposes. It’s no longer something to consider at some point down the line – it’s here now! Also, as third-party cookies become more limited, reaching users online is becoming increasingly complex and competitive. Without access to as much data, the CPMs (cost per thousand impressions) that advertisers must pay are skyrocketing because everyone is trying to bid on those same valuable consumers. It’s essential for businesses desiring success in digital advertising now more than ever before. Solving signal loss with contextual advertising How does contextual advertising help marketers engage audiences with new strategies like machine learning and artificial intelligence (AI)? Jason (Experian): Contextual advertising helps marketers engage audiences by combining advanced machine learning with privacy-safe strategies. We focus on using AI and machine learning to better understand behavior, respect privacy, and deliver insights. As third-party cookies go away, alternative identifiers are coming to market, like Unified I.D. 2.0 (UID2). These are going to be particularly important for marketers to be able to utilize them. As cookie syncing becomes outdated, marketers will have to look for alternative methods to reach their target audiences. It’s essential to look beyond cookie-reliant solutions and use other options available regarding advertising. Alex (Yieldmo): There’s been a renaissance in contextual advertising over the last couple of years. Three key drivers are shaping this shift: The loss of identity signals is forcing marketers to rethink how they reach audiences. Advances in machine learning allow us to analyze more granular contextual signals, identifying patterns that are most valuable to advertisers. Tailored models now use these signals to deliver more effective campaigns. This transformation is occurring because of our ability to capture and operate on richer, more detailed data. Reach consumers with advanced addressability How does advanced contextual advertising help marketers reach non-addressable audiences? Jason (Experian): Advanced contextual advertising helps marketers reach non-addressable audiences by taking a set of known data (identity) and drawing inferences from it with all the other signals we see across the bidstream. It’s about using a small seed set of customers, those who have transacted with you before or match your target audience, and training contextual models to make the unknown known. Now we can go out and find users surfing on any of the other sites that traditionally don’t have that identifier for that user or don’t at that moment in time and start to be able to advertise to them based on the contextually indexed data. Alex (Yieldmo): I think the exciting opportunity for many people in the industry is figuring out how to reach your known audience in a non-addressable space, that is based on environmental and non-identity based signals, that helps your campaign perform. Machine learning advancements allow you to take your small sample audience and uncover those patterns in the non-addressable space. High-quality, privacy-resilient data sets are critical for building these campaigns. Companies like Experian, with deep, rich training data, are well positioned to support advertisers in building extension audiences. Creative strategies that improve ad performance Why does creative strategy remain essential for digital advertising success? Jason (Experian): Creative strategy remains essential because it provides valuable signals for targeting and engages audiences effectively. In this advanced contextual world, good creative in the proper ad format that you can test and learn from is paramount. It comes back to that feedback loop. We can use that as another signal in this equation to develop and refine the right set of audiences for your targeting needs. Alex (Yieldmo): Creative and ad formats are powerful signals for understanding audience engagement. At Yieldmo, we collect interaction data every 200 milliseconds, such as scrolling behavior or time spent on an ad. This data fills the gap between clicks and video completions, helping us build models that predict downstream actions. Tailoring creative to specific audience groups has always been one of the best ways to improve performance, and it remains essential in this new era of contextual advertising. Throughout my career, I learned that designing or tailoring your creative to different audience groups is one of the best ways to improve performance. We ran many lift studies with analysis to understand how you can tailor creative customized for individual audiences. That capability and the ability to do that on an identity basis is. Our recommendations for actionable marketing strategies Do you have recommendations for marketers building out their yearly strategies or a campaign strategy? Jason (Experian): My recommendation for marketers building out their yearly strategies is to be proactive and start testing and learning these new solutions now. I mentioned addressability and being in the right place at the right time. That’s easier in today’s third-party cookie world. But as traditional identity is further constricted, you will have these first-party solutions that will not be at scale, so you’re less likely to find your user at the scale you want. It would be best if you thought about how to reach that user at the right place at the right time. They may not be seen from an identity basis. They might not be at the right place at the right time when you were delivering or trying to deliver an ad. But you increase your chance of reaching them by building these advanced contextual targeting audiences using this privacy-safe seed ‘opted-in’ user set; this is a way to cast that wider net and achieve targeted scale. Alex (Yieldmo): Build your seed lists, test your formats with different audiences, and understand what’s resonating with whom. Take advantage of some of the pretty remarkable advances in machine learning that are allowing us, really, for the first time to fully uncork the potential and the opportunity with contextual in a way that we’ve never done before.

In 2022, Google began changing the availability of the information available in User-Agent strings across their Chromium browsers. The change is to use the set of HTTP request header fields called Client Hints. Through this process, a server can request, and if approved by the client, receive information that would have been previously freely available in the User-Agent string. This change is likely to have an impact on publishers across the open web that may use User-Agent information today. To explain what this change means, how it will impact the AdTech industry, and what you can do to prepare, we spoke with Nate West, our Director of Product. What is the difference between User-Agents and Client Hints? A User-Agent (UA) is a string, or line of text, that identifies information about a web server’s browser and operating system. For example, it can indicate if a device is on Safari on a Mac or Chrome on Windows. Here is an example UA string from a Mac laptop running Chrome: To limit the passive fingerprinting of users, Google is reducing components of the UA strings in their Chromium browsers and introducing Client Hints. When there is a trusted relationship between first-party domain owners and third-party servers, Client Hints can be used to share the same data. This transition began in early 2022 with bigger expected changes beginning in February 2023. You can see in the above example, Chrome/109.0.0.0, where browser version information is already no longer available from the UA string on this desktop Chrome browser. How can you use User-Agent device attributes today? UA string information can be used for a variety of reasons. It is a component in web servers that has been available for decades. In the AdTech space, it can be used in various ad targeting use cases. It can be used by publishers to better understand their audience. The shift to limit access and information shared is to prevent nefarious usage of the data. What are the benefits of Client Hints? By using Client Hints, a domain owner, or publisher, can manage access to data activity that occurs on their web properties. Having that control may be advantageous. The format of the information shared is also cleaner than parsing a string from User-Agents. Although, given that Client Hints are not the norm across all browsers, a long-term solution may be needed to manage UA strings and Client Hints. An advantage of capturing and sharing Client Hint information is to be prepared and understand if there is any impact to your systems and processes. This will help with the currently planned transition by Google, but also should the full UA string become further restricted. Who will be impacted by this change? Publishers across the open web should lean in to understand this change and any potential impact to them. The programmatic ecosystem supporting real-time bidding (RTB) needs to continue pushing for adoption of OpenRTB 2.6, which supports the passing of client hint information in place of data from UA strings. What is Google’s timeline for implementing Client Hints? Source: Google Do businesses have to implement Client Hints? What happens if they don’t? Not capturing and sharing with trusted partners can impact capabilities in place today. Given Chromium browsers account for a sizable portion of web traffic, the impact will vary for each publisher and tech company in the ecosystem. I would assess how UA strings are in use today, where you may have security concerns or not, and look to get more information on how to maintain data sharing with trusted partners. We can help you adopt Client Hints Reach out to our Customer Success team at tapadcustomersuccess@experian.com to explore the best options to handle the User-Agent changes and implement Client Hints.

Up next in our Ask the Expert series, Ben Rothke, Senior Information Security Manager, reviews two certifications that should be part of your information security strategy: Service Organization Control (SOC) 2 Type 2 and International Organization for Standardization (ISO) 27001. Tapad, a part of Experian, is 27001 and SOC 2 Type 2 compliant. Two information security certifications you can trust Seals from Good Housekeeping and Underwriters Laboratories give consumers confidence that they can trust the product that they’re buying. For IT solutions or service providers, what, or who can you turn to for that seal of approval? There are many equivalent third-party attestations you can use. But which should you trust? The International Organization for Standardization (ISO) 27001 The American Institute of Certified Public Accountants (AICPA) System and Organization Controls (SOC) International Organization for Standardization (ISO) 27001 is an international standard for information security from the ISO. ISO 27001 is globally acknowledged and sets requirements for controls, maintenance, and certification of an information security management system (ISMS). This international standard provides organizations with a framework to identify, manage and reduce risks related to the security of information System and Organization Controls (SOC) The SOC, as defined by the AICPA, is a set of audit reports. SOC reports, like 27001 certificates, are used by service organizations to give their customers the confidence they have adequate information security controls in place to protect the data that they handle. SOC 2 is an assessment of controls at a service organization regarding security, availability, processing integrity, confidentiality, and privacy. The purpose of the report is to provide extensive information and assurance to a broad range of users about the controls at a service organization that are relevant to the security, availability, and processing integrity of the systems that process user data, as well as the confidentiality and privacy of the information processed by these systems. Why ISO 27001 and SOC 2 are important The value of these third-party attestations is two-fold: Organizations can show they have passed an independent external audit Third-party attestations save organizations the time of having to do their own audits In addition to 27001 and SOC 2 Type 2 compliance, we are also certified with ISO 27017 and 27018, which are add-ons to 27001 that are specific to cloud computing. We take the security and privacy of our customers’ data as seriously as they do. Every cloud service provider (CSP) has a responsibility matrix that details what security and privacy tasks they are responsible for and which ones the customer is responsible for. Any cloud customer that needs to be made aware of what their security tasks are is putting themselves at risk. So, when you want to engage a CSP, ask them for their attestations. They worked hard for them and will be proud to share their compliance. We’re powered by decades of setting standards in marketing services At Experian, we’re a privacy-first business. We’re highly focused on respecting people, their data, and their privacy. We continue to show our dedication to information security by completing these security audits every year. The constant changes to data compliance regulations can be challenging to navigate, but you don’t have to do it alone. Contact us today.
