A blog post featured image is an image that appears on the front page of a blog, or in the sidebar or footer, as a visual representation of the post. It’s usually an image that’s either representative of the content of the post, or that ties in well with the theme or tone of the post.
When picking a blog post featured image, be sure to consider both the visual appeal and the content of the post. If your blog is primarily about fashion, for example, don’t use an image of a houseplant as your featured image! Instead, try to pick an image that will represent your topic well and be visually appealing to your readers.
Finally, be sure to include a link to the original source for any blog post featured images you use. This will help readers learn more about the images and where they came from.
