However, you may sometimes forget to upload a featured image to your posts. If you have other authors posting on your site, then they may not realize the importance and skip over adding a featured image.
WordPress themes typically use featured images in multiple different areas. If you forget to add a featured image, then you may end up with lots of gaps in your website’s design including in important places like your blog archive or homepage.

People also find images more engaging than plain text. Posts that don’t have a featured image may get less traffic and lower conversion rates.
