WordPress CMS has a built in feature to assign a featured image to each of your pages/posts. Or, in case you don’t select, it automatically selects the very first image on your post as the featured image.

It might look like a desirable feature. But, if we think about it, the auto-selected image might not reflect the idea of that web page or post. Also, the image might not even be attractive enough to encourage clicks. So, we recommend you to add a custom featured image on your blog posts and pages.

As a business owner, a writer, or a blogger, you might have more time scheduled for creating and putting out the content. And, the featured image could seem unimportant to you. But, give some time to create a relevant featured image for each of your posts or pages.

But, why do you need a featured image? Firstly, the featured images visually tell users about what the post or page is about. Also, a beautifully designed featured image (aka thumbnail) attracts users to click on your post.

When a post is shared on social media, the shared link could look gibberish to the users. And, the only thing that makes sense to the viewers is the thumbnail image. So, a well-designed featured image is not only understandable, but it could entice users to click. The better the image, the higher the chances to drive clicks to your content.

Moreover, consistently designed featured images with your brand’s colors, fonts, and elements make your archive pages look professional. Plus, it subtly informs users of your brand’s personality and tone. You might have noticed it too as most professional business websites do it.

3. Name your Featured Image File
