One in six images still has no alt text — what the 2026 WebAIM Million says about your feed

In February 2026, WebAIM ran its eighth annual scan of the home pages of the top million web sites and counted 66.6 million images. Of those, 16.2% had no alternative text at all — roughly one in six, or about eleven undescribed images on a typical home page. Missing image descriptions turned up on 53.1% of the pages tested.

That number is actually moving the right way; the share of images missing alt text fell from 18.5% the year before. The problem is the figure sitting next to it in the same report: 10.8% of the images that did have alt text had questionable or repetitive text — "image," "graphic," a file name, or wording copied from the caption beside it. Put the two together and more than one in four images on the web's most-visited pages is either undescribed or described uselessly.

A filled field is not a finished job

The second number is the one worth sitting with, because it isn't a story about forgetting. Somebody was in that field. They typed something. They just didn't know what the field was asking for, so they described the file instead of the picture — which is a smaller problem to fix than apathy, and a much more common one. It's the gap that the case for alt text is meant to close: the description exists to replace the image, not to label it.

If your own archive is full of the first kind, the repair is mostly mechanical — you're not inventing meaning, you're transcribing what's already in the frame. Working through a set of side-by-side rewrites is usually enough to retrain the instinct in an afternoon.

When the picture is also the link

Here's the finding most summaries skip: 45% of the images missing alt text were linked images, and one out of every four linked images had no alt text. That failure costs a reader twice. W3C's guidance on images that act as buttons and links spells out what happens next — a screen reader will typically fall back to announcing the file name, the image URL, or the destination URL, none of which tell anyone where the link goes.

This is why the most-repeated image on your site is often the worst-described one. The header logo is a link home on nearly every page it appears, which makes alt text for logos a question about destination rather than design. The same logic applies to icon buttons, thumbnail grids, and any "read the story" image sitting above a headline. If you want to hear it the way a reader does, how screen readers announce images walks through the actual output.

What to do with this on Monday

One honest caveat before you act on it: WebAIM measured home pages, not social feeds. Nobody audits a million Instagram accounts. But the failure modes are the same ones you'd find in your own grid — the field left blank, the field filled with a file name, the linked graphic that announces nothing — and there's no reason to think a feed does better than a home page that someone was paid to build.

So start with the images you publish most and work backward. Decide deliberately which ones are decorative rather than leaving that to chance; W3C's alt decision tree settles most cases in about fifteen seconds. Then go back through the last quarter — auditing past posts for missing alt text is less work than it sounds, and it's the only way to find out which side of that one-in-six line your own account falls on.
