SEO for images — also called SEO image optimization, image optimization SEO, or simply images SEO — is the practice of optimizing your website’s images so they rank higher in Google Images, appear in AI-generated answers, and improve your overall search visibility. A good SEO image workflow includes writing descriptive alt text, using keyword-rich filenames, compressing images for speed, and adding structured data.
AI assistants like ChatGPT, Claude, and Perplexity pull answers from well-optimized content — including image metadata. Google’s AI Overviews frequently feature images with strong alt text. Without proper SEO image optimization, your visual content is invisible to both traditional search engines and the new wave of AI-powered discovery. A complete images SEO workflow is no longer optional.
ImageSEO uses AI to automatically generate descriptive alt text, rename image files with semantic keywords, and create Open Graph social cards — all in bulk. It works directly inside WordPress, processing thousands of images in minutes instead of hours of manual work.
Yes. ImageSEO is compatible with WooCommerce, Elementor, Divi, WPBakery, Gutenberg, and every major WordPress theme. Product images, gallery images, and featured images are all optimized automatically.
The WordPress plugin is free to install and includes 10 free image optimizations per month. Paid plans start at €4.99/month and raise the monthly limit (100 to 2,500 images depending on plan), with bulk optimization and social media card generation.
We started ImageSEO in 2019 because nobody on our team could stomach writing alt text for 2,000 product images by hand. What was supposed to be a weekend script turned into 6 years of data on how Google and AI assistants actually read images.
Three findings that surprised us:
alt="" tells Google and screen readers “this is decorative”. No alt attribute tells them nothing — and it’s a crawl error.The patterns on this site came from watching real sites climb rankings. Nothing here is theoretical. Every rule was extracted from plugin telemetry after we’d already shipped a bad version and seen the data come back.
