Are you harnessing the full power of images on your website? If not, you're leaving potential customers and clients on the table! It’s time to unlock the secret to drawing more eyes to your content through image search optimization. Keep reading to learn how image optimization for SEO works, including best practices to ensure you’re making the most of your website photos.


What Is Image SEO?

Image SEO is the process of optimizing images on your website to make them more discoverable by search engines. This involves using relevant file names, adding descriptive alt text, and making images the correct size for quick loading. Making the right changes for faster page load times enhances the user experience and improves your website's visibility in search engine results, particularly in image searches.


What Is Google Image Search?

Google Images is a powerful search engine provided by Google that allows users to search the web for images related to specific keywords or phrases. It indexes millions of pictures from websites across the internet, making them easily discoverable through search queries. Users can refine their searches with various filters such as size, color, type, and more to find the exact images they're looking for. While it’s great for individuals searching for images, it’s also relevant to businesses looking to improve their content’s visibility through image search optimization. 


Image Search Optimization Best Practices To Make Your Photos SEO-Friendly

The photos you use on your website, blog, and product pages aren’t just filler content. When incorporated strategically, they can have a great effect on your user engagement, improve SEO rankings, and contribute to your brand's overall storytelling. High-quality, relevant images capture attention, convey emotions, and can lead to higher conversion rates by providing visual context that complements your textual content. 


When optimized correctly, they also add another opportunity for your content to rank higher in search results. Here are six best practices for image optimization for SEO.


1. Use Descriptive File Names

Descriptive file names help search engines understand the content of your images. Instead of default names like "IMG_001.jpg," use clear, descriptive titles that reflect the image content. For example, if you have a picture of a chocolate cake to put in a recipe blog, instead of naming it "photo1.jpg," name it "chocolate-cake-recipe.jpg."


Improve Image Search SEO With These Steps:


  1. Identify the main subject of your image.

  2. Use simple, descriptive language to name your file, including relevant keywords.

  3. Replace spaces with hyphens to improve readability for search engines.


2. Add Alt Text to Images

Alt text (alternative text) describes an image's appearance and function on a webpage. It's crucial for web accessibility and helps search engines index an image properly. For example, an appropriate alt text for an image of a yoga class could be "yoga-instructor-leading-class-outdoors." Keep in mind that the alt text is a great place to incorporate keywords, but it should still describe the image (don’t “keyword stuff”).


Improve Image Search SEO With These Steps:


  1. Click on your image settings in your website's CMS.

  2. Select the option to edit the image properties.

  3. Enter a concise description in the alt text field, using keywords appropriately. 


3. Optimize Image Size and Format

Optimizing image size and format ensures faster page loading times, improving user experience and SEO rankings. Large images slow down your site, negatively affecting performance. The best file type for SEO is JPEG for high-quality photos and PNG for graphics with transparent backgrounds.


Improve Image Search SEO With These Steps:


  1. Before uploading, resize your images to the exact dimensions needed on your page.

  2. Compress images using tools like Adobe Photoshop or online compressors.

  3. Choose the right format for the image's purpose.


4. Use Responsive Images

Responsive images adjust to fit the screen size they're displayed on — making them a great choice for elevating user experience across all devices. You can use HTML code to specify different image files to be displayed on different screen sizes using the "srcset" attribute.


Improve Image Search SEO With These Steps:


  1. Prepare multiple versions of your image in different sizes.

  2. In your HTML, use the <img> tag with the "srcset" attribute to define alternative images.

  3. Test on various devices to ensure the correct image loads.


5. Leverage Image Sitemaps

An image sitemap helps search engines find images hosted on your site, improving the chances they’ll be indexed and displayed on the Google Images search engine. You can include image information in your existing sitemap or create a separate one just for images.


Improve Image Search SEO With These Steps:


  1. Create a sitemap file in XML format for your images or add image information to your current sitemap.

  2. Include the image location, title, caption, and license information.

  3. Submit your sitemap to Google Search Console.


6. Implement Structured Data

Structured data helps search engines understand the content of your images and how they relate to your site's content. Mark up product images with structured data to better the visibility in search and organic Google Shopping listings


Improve Image Search SEO With These Steps:


  1. Use schema.org to find the appropriate markup for your image type.

  2. Add the structured data to your page’s HTML.

  3. Test the implementation with Google's Schema Markup Testing Tool.


Following these image search optimization best practices will make your images more SEO-friendly, cranking up your visibility in image search results and boosting your site's overall performance.
