The image file is called IMG_0482.jpg; its alternative text is “premium handmade luxury product UAE.” Neither tells a buyer what the image shows. Start with the question the image answers: is it the product's front view, a close view of a fastening, a scale reference, or the selected color?
Google's Image SEO guidance says it uses page content, captions, image titles, alt text, and visual analysis to understand images. It recommends placing images near relevant text, using short descriptive filenames where practical, and writing useful, contextual alt text without keyword stuffing. Google describes filenames as a light clue, so a renaming project should not displace better product information and accessible descriptions.
Give each image a role
Consider a chair sold in two finishes. A main variant image might need “Oak dining chair in natural finish, front three-quarter view” so a person who cannot see it knows which finish is selected. A second image might say “Close view of the chair's woven seat and oak frame.” The product name, dimensions, stock, material specification, and care instructions belong in visible page text where everyone can inspect them. Repeating a long specification in every alt attribute makes the page harder to use.
For a purely decorative texture that adds no information, use empty alternative text. For an image that acts as a control, describe its action or destination, such as selecting the natural finish; do not leave a color swatch as an unlabeled image link. The W3C WAI image decision tree distinguishes informative, decorative, and functional images. It is a prompt for judgment, not an algorithm that can infer the image's purpose from pixels alone.
The surrounding copy matters too. Put the image close to the product detail it supports. A caption can state a visible detail that helps both sighted and non-sighted buyers; the alt text should provide the replacement information needed when the image is unavailable. If the same photo serves a different purpose on a campaign page, its alternative text may reasonably differ with that context.
A six-image review is more useful than a bulk rewrite
Take the hero image, two variant images, one close-up, one lifestyle image, and one decorative image. Open the page with images turned off or use a screen reader. Can you still identify the chosen variant and the distinguishing features? Then read the page normally: do captions and nearby text answer material, scale, and use questions without relying on the image alone? Check that a direct variant link preserves the selected image; the variant URL audit covers that path.
This is distinct from checking whether a mobile crop hides the selling detail. A sharp crop can still have poor context, and excellent alt text cannot restore a hidden visual feature. Both deserve review. For a scoped ARCHV commerce or portfolio project, we can define the image roles and content requirements before upload; a large catalog migration needs a separate asset and platform review. Better text helps understanding and access, but it does not promise an image-search position.
