Scenario: You want to target an audience that visits popular marketing websites, such as Marketing Land and Ad Age. Which targeting strategy should you use?

Contextual targeting is the correct strategy because it allows you to display ads on websites or apps that are topically relevant to your product or service. In this scenario, you want to target users who visit marketing websites, so placing ads within that specific context ensures your message reaches an interested audience. Pixel-based retargeting targets users who have previously interacted with your website, which isn't applicable here as you're looking for new audiences on third-party sites. List-based retargeting uses customer email lists for targeting, which also doesn't fit the scenario of reaching visitors on popular marketing websites. Behavioral targeting focuses on users' past online behaviors across various sites, but contextual targeting is more precise for this specific goal of appearing on marketing websites.
