What is seo product image alt filename?

Every image on a webpage has an "alt" attribute — a short text description that lives in the HTML code. When a product image is uploaded without a custom alt text, most platforms automatically fill it in with the image's filename (e.g., `IMG_4821.jpg` or `product-blue-v2_FINAL.png`). This filename tells search engines and visually-impaired shoppers absolutely nothing useful about what's actually in the photo. Descriptive alt text, by contrast, reads like a caption: "Blue cotton crew-neck sweater, front view."

Google explicitly uses alt text to understand and rank images in Google Images search, which drives meaningful, purchase-ready traffic to product pages. Filename-based alt text wastes this ranking signal entirely — a competitor with a well-written alt text will outrank you for visual searches on the same product. Beyond SEO, alt text is a legal accessibility requirement in many jurisdictions (ADA, EN 301 549, WCAG 2.1): missing or meaningless alt text can expose your store to accessibility complaints and lawsuits. Fixing it is one of the highest-ROI, lowest-effort on-page SEO tasks available to a store owner.
