A featured image is the primary image associated with a webpage or blog post, often displayed at the top of the content itself and also used automatically in social sharing previews and, in some cases, Google Discover feeds.
Choosing a high-quality, relevant, properly sized featured image matters both for on-page visual appeal and for how compelling a piece of content looks when it appears in feeds or search features that pull featured images automatically.
Featured images should include proper alt text and be optimized for file size, since they’re often among the largest individual assets loaded on a given page.
