How to Optimize Your Images for SEO
Creating SEO friendly images is simple to do, yet many website owners neglect this valuable source of search engine traffic. To make it even more simple, WordPress has some great tools built in to help you optimize your images, and you use the All-in-One SEO Pack to maximize your optimization.
The most important thing to know is that while people can see your images, search engines cannot “read” them. They can only read the words in the tags and titles you give your images. Therefore, these are the areas you want to attend to when adding images to your WordPress site.

Run an image audit: Use tools like WebSite Auditor to identify image-related SEO issues and prioritize optimization tasks.
Unique images improve SEO: Using original, high-quality images helps your website rank better in search results.
Image formats: Preferred formats for images are AVIF, JPEG 2000, JPEG XR, and WebP, with WebP being the most universal and lighter than PNG and JPEG.
Compress images: Compression can reduce image size by 60%-90%, improving page load time and SEO.
Clarify image dimensions: Specify width and height to avoid layout shifts and improve user experience.
Lazy load images: Load images only when they are visible on the user’s screen to improve page speed and user experience.
Add image alt text: Alt text describes the image to search engines and improves SEO, but avoid keyword stuffing.
Use Schema markup: Structured data helps Google understand your images and can lead to rich snippets in search results.
Protect images from theft: Add attributes like author, copyrightNotice, and source to protect your images from being stolen and to maintain SEO preference.
Two points to keep in mind:
• All images should have ALT and TITLE attributes defined. This is the image equivalent of the doc title or meta-description for the page.
• Image filenames should have a relevant name, ideally with a keyword in it. For example, an image file of “logo.jpg” might make sense to you, the website owner, but it won’t mean anything at all to a search engine. “SemperPluginsWordPressPlugins.png” is a much more descriptive, and relevant, filename.

Next time you add an image to a WordPress page or post, remember to give the image file a relevant name and fill in the spaces provided for ALT and TITLE tags. Depending on how many images you have on your site, you may want to go back and at least complete the ALT and TITLE tags.
