Semantic Image Optimizer An e-commerce image optimization method using Google's AI models and vector embeddings iteratively generated and scored product alt text, improving semantic similarity from 59% to 83% over ten attempts. The best caption, 'Four colorful fabric wristbands: red, blue, gray, and light green, are arranged diagonally on a light background,' was achieved for a Google Fitbit Air product image. The approach is part of the AI Influence app Auxy. An overview of an e-commerce image optimization method using Google's AI models and vector embeddings to iteratively generate and score product alt text. I saw a really cool post written by Gianluca Fiorelli shared on LinkedIn today https://www.linkedin.com/feed/update/urn:li:activity:7498709392712790016/ and I'd love to share how we approach image optimization for e-commerce and multi-modal AI search. The above image is located on the official Google Fitbit Air https://store.google.com/au/product/google fitbit air page. We upload the image alongside the source URL and the original alt text.
