Why image alt text is worth getting right
Alt text is the written stand-in for an image. Screen readers speak it aloud, so it's essential for shoppers who can't see the picture; browsers display it when an image fails to load; and search engines rely on it to understand what an image shows. For an online store, that's accessibility, resilience and SEO from one short attribute.
Good alt text is specific and natural. Describe what's actually in the frame, the product, its colour, the material, the setting, in a short phrase a person would say out loud. Skip 'image of' or 'photo of' (screen readers already announce it) and don't cram in keywords, which makes the experience worse for the people the attribute exists to help.
For products, alt text also opens a real traffic channel: Google Images and the Shopping tab both lean on it, and a well-described product image can surface for searches your page title never would. Keep each one under about 125 characters so screen readers don't truncate it.
Writing alt text for one image is trivial. Writing it for every image on every product, accurately, and in each language you sell in, is exactly the kind of repetitive, high-volume work that gets skipped. WISEPIM generates it from your real product data across the whole catalog, so accessibility and image SEO stop being an afterthought.
That's alt text for one image.
A product catalog has thousands of images, and most are missing alt text. WISEPIM generates accurate, descriptive alt text from your product data across every image, in every language, automatically.

Frequently asked questions
What is image alt text?
Alt text is a short written description of an image, added via the alt attribute. Screen readers read it aloud for visually impaired users, browsers show it when an image fails to load, and search engines use it to understand and rank the image.
How long should alt text be?
Keep it concise, under about 125 characters, since some screen readers cut off there. Describe what's actually in the image specifically and naturally; don't stuff keywords or start with 'image of', which screen readers already announce.
Why does product image alt text matter for e-commerce?
Good alt text makes your catalog accessible (often a legal requirement), helps products appear in Google Images and Shopping, and improves on-page SEO. With many product images per page, it's also one of the most commonly missing pieces of product data.
Can I generate alt text for my whole catalog?
Yes, WISEPIM generates descriptive, accurate alt text from your product data across every image in your catalog, in every language, and keeps it consistent as products and images change. This free tool drafts options for a single image.
What's the difference between alt text and the file name?
Both help search engines understand an image, but they do different jobs. A descriptive file name like blue-running-shoe.jpg gives a hint before the page loads, while alt text is the accessible description read by screen readers and shown if the image fails. Use clear, keyword-relevant names and write proper alt text; don't rely on the file name alone.
Do decorative images need alt text?
No. Purely decorative images, such as background flourishes or spacers, should have an empty alt attribute (alt="") so screen readers skip them. Reserve descriptive alt text for images that carry meaning, like product photos, diagrams and infographics.
