What Is a Featured Image? How to Set It Up for SEO

Besides optimizing the title and meta description, the Featured Image is also an important part of drawing viewers' attention so they click into the post. So what is Featured Image, and how do you set up an SEO-friendly Featured Image ? That is a question many people ask. In the article below, MONA Media will share a detailed, up-to-date guide on how to set it up.
What is Featured Image?
Featured Image is the image that represents a blog post, a website article or a custom post type. Among them, Post Thumbnail is the most common kind. It is an important concept because it catches the attention of visitors right away, before they read the post content.
When you click a representative image in a post (Thumbnail) the featured image also appears in the most prominent position, usually at the top of the content. Besides representing the content clearly, a featured image is closely tied to the whole theme and supported by it. However, each theme displays it differently and uses different sizes.
