What is a primary concern when ads are difficult to close on a webpage?

When ads are difficult to close on a webpage, the primary concern is that they distract from the main content. This distraction can significantly disrupt the user experience, as users may find themselves frustrated trying to navigate the page or engage with the content they originally intended to view. Such a scenario can lead to a negative perception of the website and can cause users to leave the site rather than interact with it positively.

Ads that are overly intrusive or hard to dismiss can take focus away from the information or services that a user is seeking. This distraction not only impacts user satisfaction but can also diminish the overall effectiveness of the site’s content, as the intended message may be lost amid the intrusive advertising. Therefore, while other options might touch upon aspects of ad interactions, the core issue with difficult-to-close ads is their propensity to distract users from the primary content.
