CTV advertising is not broken. The way most brands are buying, targeting, and measuring it is.
Retail brands are performance marketers at heart. Every dollar needs to work as hard as possible. That discipline is what makes great digital marketers great. But when applied directly to Connected TV, it creates a set of costly blind spots.
At this year's Modern Retail Marketing Summit, Marketing Architects Chief Media Officer Catherine Walstad laid out the three biggest illusions driving bad CTV decisions. And how to fix them.
CTV targeting looks precise. It feels precise. But CTV targets households, not individuals.
It runs on IP addresses, which are shared across devices and logins. To be useful, those IP addresses need to be mapped to a consumer profile using first and third-party data. That process is expensive and error prone. Dynamic IP assignment, shared WiFi networks, and inconsistent device-to-person mapping all introduce noise before a single impression is even served.
Truthset reports that the average accuracy rate for matching IP addresses to emails is just 16%. Obviously, advertisers would prefer that number to be north of 80%.
This gap represents a significant amount of wasted spend, and it is far from rare. Truthset says CTV advertisers are on track to waste $7 billion this year on bad identity data alone. For brands making targeting and budget decisions based on that data, the downstream effect results in audiences that look qualified on paper but are often far less defined in reality.
Narrowing your audience sounds like smart spending. In practice, it often limits growth.
When targeting gets too specific, brands miss the light buyers and category influencers who drive incremental results. Research consistently shows that light buyers, people who purchase infrequently or not at all yet, represent a large share of a brand's future growth potential. Broad reach is not waste. It is how brands grow.
The smaller the audience, the faster it gets exhausted. Frequency climbs, response drops, and the same households start seeing your ad every commercial break. That kind of overexposure actively erodes brand perception. Brands chasing tight targeting often pay full price for diminishing returns while leaving much of their addressable market untouched.
This is the most dangerous illusion because it creates false confidence.
Connected TV and linear TV are among the hardest channels to measure accurately. CTV was supposed to solve TV's measurement problems. Instead, it introduced new ones: weak control groups, overly long attribution windows, IP inaccuracies, and incrementality claims without proof to back them up. Four different measurement approaches for the same campaign can produce four wildly different results. Brands that anchor on just one set of data can easily be steered in the wrong direction.
Part of the problem is that CTV spills beyond CTV environments. Inventory bought programmatically can end up in gaming apps, lower-quality placements, and other non-premium contexts that inflate impression counts without delivering high-attention reach likely to drive qualified customers.
Ad fraud compounds the problem. Most CTV inventory is bought programmatically. Without protections in place, DoubleVerify finds that more than 1 in 4 CTV video impressions are lost to fraud.
Despite all of this, 83% of marketers are planning to maintain or grow their CTV investment over the next two to three years. The brands that win will not be the ones spending more. They will be the ones spending smarter.
CTV still represents one of the biggest opportunities in advertising right now. The brands that get ahead will be the ones that stop chasing the illusion of precision and start investing in the tools that give them clarity.
