Search Engine Optimization

Image SEO

SEO involves a wide range of different aspects, so it can be easy for businesses to overlook some of the smaller steps to practice good on-site SEO. However, anything you can do to reinforce the SEO of your website makes a real difference – especially if it’s something other sites might overlook.

It is a simple and important step to make your website more competitive in search engines by taking time to optimize your images for SEO.

It’s kind of a little thing that many businesses let the cracks slip through, but makes it so much more worthwhile to do.

Looking to enhance the Image SEO on your website? The image search can bring many new visitors to your website when optimized correctly.

To benefit from the image SEO, search engines need to help find your images and index them for the right keywords.

We’ll show you in this guide how to optimize the SEO image by following top best practices.

Use relevant, high-quality images

This is important for the SEO side of user experience. An image that is unrelated to the page’s content will be confusing to the user and one that’s blurry or badly cropped will just make your page look bad and unprofessional. If you run an online shop, optimizing the image is an art you’d have to learn. Image optimization is a vital aspect of creating a good eCommerce website – from attracting buyers, perusing Google photos towards-site load times. Make sure that every image you use is clearly related to what is on the page, and looks good.

You must be careful not to use any images you don’t have the right to, but you can find lots of online resources that can be used by businesses providing free images. Commit some time to find at least one good picture to include for each page you create and blog post; bonus points if you can find a few.

Optimize the Alt Tag

Alt attributes are an alternative text to images when a browser fails to render them appropriately. Even if the image is rendered, you will see the text of the alt attribute (depending on your web browser) if you hover over it. This is another aspect of the website that most users won’t see, but crawlers do.

The alt attribute provides SEO value for your website as well. Adding correct alt attributes to the images on your website which should include relevant keywords and will help you rank better in the search engines. As a matter of fact, using alt attributes is possibly the best way to show up in Google image and web search for your eCommerce goods.

Always update your images with Alt Text. Include your primary page keyword and something descriptive of the picture itself. If you are using WordPress, you can fill in an alt text field to do so.

Optimizing the size matters

Speed plays a major role in both SEO and user experience. Search engines typically rate higher fast websites. It is valid for the search of images, too.

When a customer arrives on your site, loading everything can take a while, depending on how big your files are. The larger the file sizes, the longer it takes to load a website. If you can decrease the image file size on your website and increase page load speed, fewer people visiting your website will click away.

You can make your site faster by resizing your image files when you upload them to your website even while displaying images at a high resolution. This is also simple to do with applications that are standard on most machines, such as the Mac Preview or Microsoft Paint. And if you have Adobe Photoshop, you can use the “Save for Web” option to help you seek the minimum file size that still gives an excellent resolution.

Disable Attachment Pages in WordPress

For all images that you upload to your posts and pages, WordPress creates a web page called the attachment page. This page shows just a larger version of the image, and nothing else.

This can impact your search rankings negatively on the SEO. Search engines consider the low quality or ‘thin content’ of pages with little to no text.

This is why we recommend that users disable the pages attached to your website.

This can be done by any image optimization plugin like Yoast etc. Another way to solve this issue is by using a redirecting plugin and redirecting the visitors of the attachment page to an actual content page. By doing so, you can also extra traffic to your website.

This can also be done manually, by adding the following code to the functions.php file of your theme

function wpb_redirect_attachment_to_post() {

if ( is_attachment() ) {

global $post;

if( empty( $post ) ) $post = get_queried_object();

if ($post->post_parent)  {

    $link = get_permalink( $post->post_parent );

    wp_redirect( $link, ‘301’ );



else      {

    // What to do, if parent post is not available

    wp_redirect( home_url(), ‘301’ );



add_action( ‘template_redirect’, ‘wpb_redirect_attachment_to_post’ );

Selecting the correct format

You may have noticed three main types of image files, but you may not really understand the difference between them. Understanding the different types of files can help you select the best one for your needs:

The next-gen formats

Apart from the standard formats, the so-called next-gen image formats such as WebP, JPEG 2000, and JPEG XR can also be accessed.

They are even suggested in Google PageSpeed Insights as Go-to formats: WebP, in particular, is one to pay close attention to, as Google developed it to serve high-quality images in smaller sizes.

Google studies have shown that WebP images can save more space and resources for websites than their traditional counterparts in JPEG and PNG.

The only major issue is that the WebP and other next-gen formats do not yet have 100% browser support.

Image SEO Wrapping Up

Image SEO is the easiest one while comparing with other SEO factors. You can give your pages an extra edge in the search engines by committing a little extra time to find the right images and optimizing them for search engines – each time you add a page to your website.
