A featured image is the image or visual that represents the content of a web page or a post. It generally appears on top of your page, designed to grab the attention of your readers.

Also, the featured image in WordPress automatically becomes the default thumbnail. So, when displayed in archive pages, content layout pages, the displayed image there is your featured image.

Moreover, when a web page or blog is shared, the featured image is what people see on chats and social media channels.

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.


Before creating your featured image, the first thing you should know is the appropriate size and dimension. This brings us to –

Why do you need a Featured Image?

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.

This is an example of a featured image appearing on the blog archive page of our site Marketing With WP. Here, we’ve used descriptive text and visual illustration to inform users about the content of the 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.

Here’s what our blog archive looks like:

Images search in Google and other search engines are also a good source for website traffic. A well-optimized featured image has a high likelihood of appearing in Google’s Image Search.

Here are some tips for optimizing your Featured Images to appear in searches.

1. Use alt tags

We’ve already mentioned that the featured image lets you enter alt tags. They describe search engines about the image so they can appear in relevant search terms. So, make proper use of image alt tags to optimize your featured image.

2. Use Custom Images

With an eye-catching design, it’s liable to get attention, clicks, and thus traffic for your website. Thus, we recommend using custom images rather than just using a plain image. Throw in some graphics, descriptive texts, your brand logo, and so on.

People are not much concerned about featured images. So, you can take it to your advantage. On Google searches, your custom-designed featured image can stand out among your competitors. Thus, you steal the traffic.

3. Name your Featured Image File

The image title has no effect on SEO as search engine bots only crawl the image alt text. However, it’s a good practice to give appropriate and descriptive titles to your featured images. It would be understandable for the users nonetheless.
