What could be a consequence of inadequate alt text for images?

Inadequate alt text for images leads to a significant reduction in accessibility for users relying on screen readers. Screen readers interpret alt text to describe images to users who are visually impaired. When alt text is missing, poorly written, or not descriptive enough, these users may miss essential information or context provided by the images. This can create barriers to understanding web content, resulting in a frustrating experience and an inability to fully engage with the site.

Other options do not directly relate to the issue at hand. For instance, while search engine rankings can indeed be impacted by various accessibility factors, the relationship with alt text specifically is not as straightforward and does not align as directly with the core issue of providing accessible content for those relying on assistive technologies. Similarly, navigation improvements and visual clarity are not relevant consequences of inadequate alt text, as they pertain to different aspects of web usability and accessibility.
