Iterative E-commerce Image Alt Text Optimization Using Semantic Vectors
dejanseo · x · 2026-08-30
Dejan.ai showcases an e-commerce image optimization method using Google's latest model to generate vector embeddings for semantic similarity scoring.
Workflow:
- Upload the product image, source URL, and original alt text.
- If no alt text exists, start the run with a blank value.
- The model scores generated descriptions based on semantic similarity and iteratively optimizes them.
Optimization Example (Fitbit wristbands):
- Initial match: 59%.
- Step 2 increased match to 82% (+19%).
- Subsequent attempts refined details (material, color), fluctuating between 79%-83% to find the best semantic fit.
