Which of the following impacts the effectiveness of display ads?

The effectiveness of display ads is greatly influenced by the design, placement, and content of the ad. This is because these elements directly impact how well the ad captures attention and communicates the intended message to the audience.

A well-designed ad that aligns with the target audience's interests can significantly increase engagement rates. Additionally, the placement of the ad on a website is crucial; an ad that is positioned prominently might be seen more frequently and by more people than one that is hidden or poorly positioned. Furthermore, the content of the ad—including the images, text, and call-to-action—needs to resonate with viewers to encourage them to engage with it.

In contrast, while the color scheme of the website may play a role in the overall user experience, it is not solely responsible for the ad's effectiveness. Email marketing strategies and timing can also influence overall marketing campaigns but are not directly related to the display ads themselves. Therefore, the combination of design, placement, and content is fundamental to maximizing the impact of display ads.
