Váš kolega chce skontrolovať štúdiu vplyvu na značku na zaručenej programovej dohode pre novú zvukovú reklamu svojho klienta. Keď v službe Display & Video 360 vygeneruje štúdiu vplyvu na značku, nezistí pri tejto dohode žiadne významné výsledky. Čo by mohla byť príčina?

The correct answer is that brand lift cannot be measured on guaranteed programmatic deals. Brand lift studies in Display & Video 360 are typically conducted on open auction or non-guaranteed programmatic inventory, where there's more flexibility in serving survey pixels to a randomized control group. Guaranteed programmatic deals often involve pre-negotiated terms and fixed inventory, which can limit the ability to implement the necessary survey methodology for a brand lift study. While brand lift can be measured for audio ads (eliminating the first incorrect option), and Display & Video 360 does support brand lift measurement generally (eliminating the third incorrect option), the specific constraint here is the deal type. The brand lift report can be viewed once data is collected, so the second incorrect option is also not the primary reason for a lack of results.
